Listeria infection is usually found in immunocompromised patients, including elderly people, pregnant women, and newborns, whereas it is rare in healthy people. L.monocytogenes may cause meningitis, meningoencephalitis, and some very rare and severe complications, such as hydrocephalus and intracranial hemorrhage,which cause high mortality and morbidity worldwide. Up to now, reports on hydrocephalus and intracranial hemorrhage due to L. monocytogenes are few.CASE SUMMARY We herein report a case of rhombencephalitis caused by L. monocytogenes in a 29-year-old man. He was admitted to the hospital with a 2-d history of headache and fever. He consumed unpasteurized cooked beef two days before appearance.His medical history included type 2 diabetes mellitus, and contaminated beef intake 2 d before onset. Cerebrospinal fluid analysis revealed Gram-positive rod infection, and blood culture was positive for L. monocytogenes. Magnetic resonance imaging findings suggested rhombencephalitis and hydrocephalus.Treatment was started empirically and then modified according to the blood culture results. Repeated CT images were suggestive of intracranial hemorrhage.Although the patient underwent aggressive external ventricular drainage, he died of a continuing deterioration of intracranial conditions.CONCLUSION Hydrocephalus, intracranial hemorrhage, and inappropriate antimicrobial treatment are the determinations of unfavorable outcomes.展开更多

During the follow-up period,only one case had slight activity limitation on one side of the limb,but steadily recovered.Besides the decreased concentration of FⅧ,trauma is the most common risk factor of ICH in children with hemophilia A.The active treatment can improve the prognosis of ICH in children with hemophilia A.展开更多

Radiotherapy is an important part of treatment for NPC patients, especially those with stage Ⅲ/Ⅳ disease. Subdural empyema is a rare but life-threatening complication in postradiotherapy NPC patients which should be paid more attention. Here, we present the case of a 64-year-old female postradiotherapy NPC patient with subdural empyema complicated with intracranial hemorrhage. She was treated by burr-hole surgery but unfortunately died because of recurrent intracranial hemorrhage. The mechanisms potentially underlying the formation of subdural empyema in postradiotherapy NPC patients and the surgical strategies that can be used in these patients are discussed in this report.展开更多

Minimally invasive intracranial hematoma drainage was performed on the minimally invasive group. Bone flap decompression or small bone window craniotomy were used in the routine group. Tumor necrosis factorα (TNF-α), interleukin-6 (IL-6), high sensitive C reactive protein (hs-CRP) and serum protein (SF), serum substance P (SP) in the 2 groups were detected before treatment and 2 weeks after treatment.Results: The comparison of TNF-α, IL-6, hs-CRP, SP, and SF in the two groups before treatment was not statistically significant (P>0.05). TNF-α, IL-6, hs-CRP and SF in both groups after treatment significantly decreased, compared with that before treatment (P<0.01,P<0.05). TNF-α, IL-6, and SF in minimally invasive group decreased more significantly than that in routine group (P<0.01);The comparison of SP in the two groups after treatment significantly increased compared with that before treatment (P<0.01,P<0.05). SP in minimally invasive group increased more significantly than that in routine group (P<0.05).Conclusions:Compared with bone flap decompression or small bone window craniotomy, minimally invasive intracranial hematoma drainage can inhibit inflammatory reaction, reduce the degree of nerve damage and alleviate clinical symptoms more effectively.展开更多

OBJECTIVE: To explore the rules about the changes of intracranial pressure in brainstem hemorrhage and internal capsule hemorrhage, and analyze the role of intracranial hypertension in the changes of nerve function caused by cerebral hemorrhage. DESIGN: A self-controlled trial. SETTING: Department of Physiology, Tianjin Medical University. MATERIALS: Sixty-five healthy male Japanese white rabbits with long ears (1.5-1.8 kg) were supplied and fed by the Department of Animal Experiment of Tianjin Medical University. The RM6240B biological signal collecting and processing system was used. METHODS: The experiments were conducted in the Department of Physiology, Tianjin Medical University from August 2001 to May 2006. ① The rabbits were anesthetized, then fixed onto the brain stereotaxic apparatus, and afterwards fenestration on skull and intubation to lateral ventricle were performed.The dynamic changes of intracranial pressure were monitored continuously. Rabbits were infused with autologous arterial blood (0.3 mL) into midbrain corpora quadrigemina inferior colliculus to induce model of acute brainstem hemorrhage; models of internal capsule hemorrhage were established by infusing autologous arterial blood into internal capsule. ② The dynamic intracranial pressures under the above conditions were recorded continuously with the RM6240B biological signal collecting and processing system. ③ An animal model of persistent intracranial hypertension was established by infusion of physiologic saline into lateral ventricle. ④ The changes of the intensity of autonomic nerve discharge were analyzed, using the biological signal collecting and processing system before and after hemorrhage and under persistent intracranial hypertension.⑤ Ten animal models of internal capsule hemorrhage and 10 of bminstem hemorrhage were selected respectively, then gross pathological samples were cut open, and the accuracy of hemorrhage models was affirmed. Histological sections in hemorrhage point and around this point were prepared for with hernatoxylin and eosin staining, and the pathological changes were observed under light microscope. MAIN OUTCOME MEASURES: ① Changes of intracranial pressures before and after internal capsule hemorrhage and brainstem hemorrhage; ②Changes of the discharge intensity of cervical vagus nerve trunk in animal models of internal capsule hemorrhage, brainstem hemorrhage and persistent intracranial hypertension without hemorrhage; ③ Accuracy of location of internal capsule hemorrhage and brainstem hemorrhage confirmed by gross pathological samples and sections. RESULTS: Totally 65 rabbits were involved in the analysis of results. ① Dynamic state of intracranial pressure: Intracranial pressure increased obviously at 45 minutes after internal capsule hemorrhage and brainstem hemorrhage, the intracranial pressures were (1.31 ±0.30), (1.82±0.45) kPa, which were obviously higher than those before hemorrhage [(1,04±0.18), (1.05±0.19) kPa, P 〈 0.01]. ② Discharge of vagus nerve: Under intracranial hypertension, the discharge of cervical vagus nerve trunk was enhanced, and the discharge intensity of vagus nerve trunk was significantly different before and after persistent intracranial hypertension [(364.28±78.55), (1252.19±151.75)μ V·s, P 〈 0.01]. The discharges of cervical vagus nerve trunk were significantly enhanced after internal capsule hemorrhage and brainstem hemorrhage (P 〈 0.01). ③ Validation of hemorrhage sites: The hemorrhage sites were internal capsule and brainstem on histopathological sections. CONCLUSION: Intracranial pressure may play an important role in the pathophysiological process of vagus nerve imbalance caused by cerebral hemorrhage.展开更多

Imaging study is important for the correct diagnosis at birth and documentation of one of the diagnosis criteria (absence of radius) in prenatal care. The main hematologic symptoms and the most feared of them, intracranial bleeding, occurs when platelets levels are below 10,000/mm<sup>3</sup>, which is more common during the first months. Therefore, imaging study is crucial to quickly identify complications and correctly manage the case. In this case report, the patient had upper limps alterations at birth and at first week presented seizures, with transfontanellar ultrasound and head computed tomography without contrast demonstrating intracranial hemorrhage. Laboratory results and imaging review were able to diagnose TAR syndrome. The patient was treated with platelets transfusion and thrombocytopenia was solved. She is currently under specialized medical care, with no neurological deficits and showing satisfactory development.展开更多

Therefore, diagnosis and treatment of intracranial hemorrhage in time become a key factor for improving healing rate and reducing fatality rate and incidence of sequela. OBJECTIVE: To investigate the clinical situation, experimental characteristics, CT examination and terminative characteristics of infants with intracranial hemorrhage induced by delayed vitamin K deficiency. DESIGN: Case analysis. SETTING: Department of Pediatrics, Zhongshan Hospital Affiliated to Xiamen University. PARTICIPANTS: A total of 17 infants with intracranial hemorrhage induced by delayed vitamin K deficiency aged 1-3 months including 11 boys and 6 girls were selected from Department of Pediatrics, Zhongshan Hospital Affiliated to Xiamen University from January 1994 to December 2005. All infants had drowsiness, rejective milk, spiting milk, gaze of both eyes, tic, coma, full anterior fontanelle, high muscular tension and cerebral hernia, etc. Experimental examination demonstrated that infants had anemia at various degrees; prothrombin time and partial thromboplastin time were prolonged; platelet count was normal. CT examination indicated that screenages of subarachnoid hemorrhage, subdural hematoma, cerebral parenchyma hemorrhage and intraventricular hemorrage were changed. Hemorrhage was stopped by the application of vitamin K. All patients provided informed consent. METHODS: ① Clinical situation and physical sign of infants were observed after hospitalization and scanned with rapid spiral CT scanning system. The thickness and average space of layers were 8-10 mm and the scanning time was 5 s with window width of 30-80 Hu and window position of 28-35 Hu. ② After hospitalization, four items of blood coagulation was measured with Futura meter and biochemical indexes of blood, such as serum calcium, serum alkaline phosphatase, total bilirubin, direct bilirubin and indirect bilirubin, were detected with Roche Modular PPI automatic biochemistry analyzer. ③ After hospitalization, infants were given 5-10 mg vitamin K1 for 3-5 days, and then, they were transfused with 10-15 mL/kg fresh plasma or whole blood for 1-3 times and received other relative therapies. Therapeutic effects were evaluated based on clinical diagnosis and criteria. MAIN OUTCOME MEASURES: ① Clinical situation, physical sign and CT examination; ② results of experimental examination; ③ treatment and termination. RESULTS: A total of 17 infants with intracranial hemorrhage were involved in the final analysis. ① Clinical situation, physical sign and CT examination: All infants had pale facial expression and full or bossing anterior fontanelle. Among them, 13 infants had drowsiness or dysphoria, 12 rejective milk or emesis, 11 tic, 13 injection site hemorrhage, 2 gastrointestinal hemorrhage, 3 cerebral hernia, 11 high muscular tension and 6 cervical rigidity. CT examination demonstrated that most infants (88%, 15/17) had subarachnoid hemorrhage; 10 (59%, 10/17) had subdural hematoma; 8 (47%, 8/17) had cerebral parenchyma hemorrhage; few had intraventricular hemorrhage. In addition, results of CT examination also indicated that 17 infants had intracranial hemorrhage. Hemorrhage sites of 12 infants were equal to or more than 2, which was accounted for 70% (12/17); meanwhile, partial cases accompanied with a large area of focus of cerebral infarction or cerebral hypoxia-ischemia lesion. ② Results of experimental examination: There were 6 infants with elongation of prothrombin time, 5 with partial elongation of prothrombin time, 4 with decrease of serum calcium (1.69-2.25 mmol/L), 3 with increase of serum alkaline phosphatase, 3 with increase of total bilirubin, 3 with increase of direct bilirubin, and 3 with increase of indirect bilirubin. ③ Treatment and termination: After treatment, 12 infants were cured well, 3 improved, 1 given up and 1 died. Later, ten infants received CT re-examination at 3 months after treatment. The results indicated that 3 infants had simple subarachnoid hemorrhage and 4 had subarachnoid hemorrhage accompanying with subdural hematoma. Their focuses were absorbed well and not show as obvious sequela. One infant had subdural hematoma accompanying with subarachnoid hemorrhage, cerebral parenchyma hemorrhage, intraventricular hemorrage and cerebral hypoxia ischemia, and then, after hematom absorption, obvious cerebral malacia focus, hydrocephalus, brain atrophy and inferior accumulating fluid of dura mater were observed; 2 had subdural hematoma accompanying with subarachnoid hemorrhage and cerebral hypoxia ischemia, and then, after bleeding absorption, brain atrophy was changed remarkably; changes of hydrocephalus were observed in one infant. CONCLUSION: ① Symptoms of pale facial expression, full or bossing anterior fontanelle, drowsiness and dysphoria are observed in infants with delayed vitamin K deficiency . ② Experimental indexes demonstrate that prothrombin time and partial prothrombin time are prolonged, and numbers of infants having decrease of serum calcium are in the third place. ③ Poly-intracranial hemorrhage is a notable characteristic of CT examination. Partial infants who have poly-intracranial hemorrhage always accompany with cerebral hypoxia-ischemia lesion or cerebral infarction. Clinical situation and prognosis of infants who have a large area of intracranial hemorrhage and cerebral hypoxia-ischemia changes are poor; however, those of infants who have simple subarachnoid hemorrhage or combination of subarachnoid hemorrhage with subdural hematoma are well. ④ Effect of vitamin K on this kind of disease is well.展开更多

Methods: The patients who were hospitalized for hypertensive cerebral hemorrhage between August 2014 and February 2017 were selected as the cerebral hemorrhage group and healthy subjects who received physical examination during the same period were selected as the control group;TCD was used to determine the PI of affected-side and unaffected-side middle cerebral artery in cerebral hemorrhage group and lumbar puncture was done to measure intracranial pressure. The serum was collected from the two groups to detect the levels of inflammatory cytokines and nerve injury markers. Results: PI level in affected-side middle cerebral artery of cerebral hemorrhage group was significantly higher than that in the unaffected-side and positively correlated with intracranial pressure level;serum IL-1β, TNF-α, ICAM-1, MMP9, YKL-40, Asp, Glu, NPY, NSE and GFAP levels of cerebral hemorrhage group were significantly higher than those of control group, and serum IL-1β, TNF-α, ICAM-1, MMP9, YKL-40, Asp, Glu, NPY, NSE and GFAP levels of cerebral hemorrhage group of patients with high PI level were significantly higher than those of cerebral hemorrhage group of patients with low PI level. Conclusion: TCD parameters can evaluate the degree of intracranial pressure increase and nerve injury in patients with hypertensive cerebral hemorrhage.展开更多

The patients in the two groups were given drug conservative treatments. On this basis, the patients in the minimally invasive group were given urokinase in combined with minimally invasive hematoma puncture with YL-1 type needle. TCD was performed before treatment, 1 d, 5 d, 10 d, and 21 d after treatment. The hematoma and edema volume was calculated. NIHSS was used to evaluate the neurological function recovery.Results: Vs, Vd, and Vm after treatment in the minimally invasive group were significantly elevated, while PI was significantly reduced. Vs, Vd, and Vm after treatment in the conservative group were reduced first and elevated later, while PI was elevated first and reduced later, and reached the lowest/peak 10d after treatment. Vs, Vd, and Vm 5 d, 10 d, and 21 d after treatment in the minimally invasive group were significantly higher than those in the conservative group, while PI was significantly lower than that in the conservative group. The hematoma and edema volume after treatment in the two groups was significantly reduced. The hematoma and edema volume at each timing point was significantly lower than that in the conservative group. NIHSS score after treatment in the minimally invasive group was significantly reduced. NIHSS score in the conservative group was elevated first and reduced later, reached the peak 10d after treatment, and at each timing point was higher than that in the minimally invasive group.Conclusions:The early minimally invasive operation can significantly improve the hematoma adjacent blood flow volume in patients with hypertensive cerebral hemorrhage, and contribute to the neurological function recovery.

文摘In this editorial we comment on the article published by Zhang et al in the recent issue of World Journal of Clinical Cases.We evaluate their claims on the benefit of use of Aspirin in the early management of patients with ischemic stroke.We also comment on their contention of using aspirin in the early management of patients with intracranial hemorrhage,a practice not seen in modern medicine.Large clinical trials such as the International Stroke Trial and the Chinese Acute Stroke Trial have shown the benefit of Aspirin use within 48 h of patients with Acute Ischemic Stroke.The findings were corroborated in the open-label trial performed by Zhang et al in a smaller sample group of 25 patients where they showed improvement in functional scores at 90 days without an increase in adverse events.As such,this intervention is also recommended by the American Heart Association stroke guidelines from 2021.With regard to Intracranial hemorrhage,traditional practice has been to discontinue or avoid antiplatelet therapy in these patient groups.However,no studies have been done to evaluate this management strategy that is more borne out of the mechanism behind Aspirin’s effect on the coagulation pathway.Zhang et al evaluate the benefits of Aspirin on patients with low-volume intracranial hemorrhage,i.e.,less than 30 mL on computed tomo-graphy imaging,and show no increase in mortality.The caveat of this finding is that all outcomes were pooled into one group for results,and the number of patients was low.While more studies with larger patient groups are required,the data from Zhang et al suggests that patients with small-volume intracranial hemorrhages may benefit from Aspirin administration in the acute phase of management.

文摘Intracranial hemorrhage(ICH)causes numerous neurological deficits and deaths worldwide each year,leaving a significant health burden on the public.The pathophysiology of ICH is complicated and involves both primary and secondary injuries.Hematoma,as the primary pathology of ICH,undergoes metabolism and triggers biochemical and biomechanical alterations in the brain,leading to the secondary injury.Past endeavors mainly aimed at biochemical-initiated mechanisms for causing secondary injury,which have made limited progress in recent years,although ICH itself is also highly biomechanics-related.The discovery of the mechanically-activated cation channel Piezo1 provides a new avenue to further explore the mechanisms underlying the secondary injury.The current article reviews the structure and gating mechanisms of Piezo1,its roles in the physiology/pathophysiology of neurons,astrocytes,microglia,and bone-marrow-derived macrophages,and especially its roles in erythrocytic turnover and iron metabolism,revealing a potential interplay between the biomechanics and biochemistry of hematoma in ICH.Collectively,these advances provide deeper insights into the secondary injury of ICH and lay the foundations for future research.

文摘BACKGROUND Intracranial hemorrhage after spinal surgery is a rare and devastating complication.AIM To investigate the economic burden,clinical characteristics,risk factors,and mechanisms of intracranial hemorrhage after spinal surgery.METHODS A retrospective cohort study was conducted from January 1,2015,to December 31,2022.Patients aged≥18 years,who had undergone spinal surgery were included.Intracranial hemorrhage patients were selected after spinal surgery during hospitalization.Based on the type of spinal surgery,patients with intracranial hemorrhage were randomly matched in a 1:5 ratio with control patients without intracranial hemorrhage.The patients'pre-,intra-,and post-operative data and clinical manifestations were recorded.RESULTS A total of 24472 patients underwent spinal surgery.Six patients(3 males and 3 females,average age 71.3 years)developed intracranial hemorrhage after posterior spinal fusion procedures,with an incidence of 0.025%(6/24472).The prevailing type of intracranial hemorrhage was cerebellar hemorrhage.Two patients had a poor clinical outcome.Based on the type of surgery,30 control patients were randomly matched in 1:5 ratio.The intracranial hemorrhage group showed significant differences compared with the control group with regard to age(71.33±7.45 years vs 58.39±8.07 years,P=0.001),previous history of cerebrovascular disease(50%vs 6.7%,P=0.024),spinal dura mater injury(50%vs 3.3%,P=0.010),hospital expenses(RMB 242119.1±87610.0 vs RMB 96290.7±32029.9,P=0.009),and discharge activity daily living score(40.00±25.88 vs 75.40±18.29,P=0.019).CONCLUSION The incidence of intracranial hemorrhage after spinal surgery was extremely low,with poor clinical outcomes.Patient age,previous stroke history,and dura mater damage were possible risk factors.It is suggested that spinal dura mater injury should be avoided during surgery in high-risk patients.
文摘BACKGROUND Subarachnoid hemorrhage is a severe neurological condition that requires prompt and appropriate treatment to prevent complications.Aneurysms are the most common cause of spontaneous subarachnoid hemorrhage.Conversely,basilar artery perforator aneurysms(BAPAs)are a rare etiology.There is no consensus on the optimal management of ruptured BAPAs in the acute setting.CASE SUMMARY We present a case series of 3 patients with ruptured BAPAs who were treated at our institution.Two patients had a modified Fisher grade of I,and one had a grade of IV on initial presentation.The aneurysms were detected by computed tomography angiography in two cases and conventional angiography in one case.The 3 patients underwent endovascular treatment with Guglielmi detachable coils.Post-treatment,the patients had good clinical outcomes,and follow-up brain computed tomography scans showed reduced subarachnoid hemorrhage without any new hemorrhage.However,one patient experienced a cerebral infarction 2 months later and eventually succumbed to the condition.The other 2 patients showed progressive recovery,and no aneurysm recurrence was observed at the 2-year follow-up.CONCLUSION Endovascular treatment may be a preferable approach for managing ruptured BAPAs compared with surgical intervention or conservative management.Early detection and prompt treatment is important to achieve favorable patient outcomes.
文摘BACKGROUND:The incidence of hypertensive intracerebral hemorrhage(HICH)has been increasing during the recent years in low-and middle-income countries.With high mortality and morbidity rates,it brings huge burden to the families.It lacks evidence regarding the application of intracranial pressure(ICP)monitoring in HICH.In the current study,the authors aimed to evaluate whether ICP monitoring could make any difference on the prognosis of HICH patients after minimally invasive surgery.METHODS:A retrospective review of 116 HICH patients admitted to the Second Affiliated Hospital of Zhejiang University School of Medicine,between 2014 and 2016,was performed.The effects of ICP monitoring on 6-month mortality and favorable outcomes were evaluated by univariate and logistic regression analysis.RESULTS:ICP monitors were inserted into 50 patients.Patients with ICP monitoring had a significantly better outcome(P<0.05).The average in-hospital duration in patients with ICP monitoring was shorter than that in the patients without ICP monitoring(16.68 days vs.20.47 days,P<0.05).Mortality rates between ICP monitoring and no ICP monitoring did not differ significantly(16.0%vs.15.1%,P=0.901).On univariate analysis,age,Glasgow Coma Scale(GCS)on admission and presence of ICP monitor were independent predictors of 6-month favorable outcomes.CONCLUSION:ICP monitoring is associated with a better 6-month functional outcome compared with no ICP monitoring.Future study is still needed to confirm our results and elucidate which subgroup of HICH patients will benefit most from the minimally invasive surgical intervention and ICP monitoring.

文摘BACKGROUND Listeria monocytogenes(L. monocytogenes), a Gram-positive facultatively intracellular bacterium, is the causative agent of human listeriosis. Listeria infection is usually found in immunocompromised patients, including elderly people, pregnant women, and newborns, whereas it is rare in healthy people. L.monocytogenes may cause meningitis, meningoencephalitis, and some very rare and severe complications, such as hydrocephalus and intracranial hemorrhage,which cause high mortality and morbidity worldwide. Up to now, reports on hydrocephalus and intracranial hemorrhage due to L. monocytogenes are few.CASE SUMMARY We herein report a case of rhombencephalitis caused by L. monocytogenes in a 29-year-old man. He was admitted to the hospital with a 2-d history of headache and fever. He consumed unpasteurized cooked beef two days before appearance.His medical history included type 2 diabetes mellitus, and contaminated beef intake 2 d before onset. Cerebrospinal fluid analysis revealed Gram-positive rod infection, and blood culture was positive for L. monocytogenes. Magnetic resonance imaging findings suggested rhombencephalitis and hydrocephalus.Treatment was started empirically and then modified according to the blood culture results. Repeated CT images were suggestive of intracranial hemorrhage.Although the patient underwent aggressive external ventricular drainage, he died of a continuing deterioration of intracranial conditions.CONCLUSION Hydrocephalus, intracranial hemorrhage, and inappropriate antimicrobial treatment are the determinations of unfavorable outcomes.
文摘To investigate the incidence,risk factors,clinical manifestations and prognosis of intracranial hemorrhage (ICH)in children with hemophilia A in a center of China, we conducted a retrospective analysis of 126 children with hemophilia A at our hospital in recent 4 years.Thirty-six children with hemophilia A (including 19 severe cases,and 17 moderate cases complicated with joint diseases)received low dose factor Ⅷ (FⅧ) prophylaxis,and none of them had ICH.However,13 cases of hemophilia A not given prophylaxis were complicated with ICH (12 severe cases,and 1 moderate case)and demonstrated an incidence of 10.3%(13/126)in all patients,and 28.6%(12/42)in severe cases.Of the 13 cases,9 severe ICH cases had a definite history of head injury,accounting for 69.2%.Headache was common in children >3 years,but somnolence,irritability, gaze or convulsions in children <3 years.The most common findings of cranial CT scan included intracranial hematoma (9/13),and less commonly observed were subependymal hemorrhage and intraventricular hemorrhage.After administration of FⅧ,all patients survived.Hematoma of 6 cases was observed during CT reexamination after 1-3 months. During the follow-up period,only one case had slight activity limitation on one side of the limb,but steadily recovered.Besides the decreased concentration of FⅧ,trauma is the most common risk factor of ICH in children with hemophilia A.The active treatment can improve the prognosis of ICH in children with hemophilia A.

文摘BACKGROUND High-grade aneurysmal subarachnoid hemorrhage is a devastating disease with a low favorable outcome.Elevated intracranial pressure is a substantial feature of high-grade aneurysmal subarachnoid hemorrhage that can result to secondary brain injury.Early control of intracranial pressure including decompressive craniectomy and external ventricular drainage had been reported to be associated with improved outcomes.But in recent years,little is known whether external ventricular drainage and intracranial pressure monitoring after coiling could improve outcomes in high-grade aneurysmal subarachnoid hemorrhage.AIM To investigate the outcomes of high-grade aneurysmal subarachnoid hemorrhage patients with coiling and ventricular intracranial pressure monitoring.METHODS A retrospective analysis of a consecutive series of high-grade patients treated between Jan 2016 and Jun 2017 was performed.In our center,followed by continuous intracranial pressure monitoring,the use of ventricular pressure probe for endovascular coiling and invasive intracranial pressure monitoring in the acute phase is considered to be the first choice for the treatment of high-grade patients.We retrospectively analyzed patient characteristics,radiological features,intracranial pressure monitoring parameters,complications,mortality and outcome.RESULTS A total of 36 patients were included,and 32(88.89%)survived.The overall mortality rate was 11.11%.No patient suffered from aneurysm re-rupture.The intracranial pressure in 33 patients(91.67%)was maintained within the normal range by ventricular drainage during the treatment.A favorable outcome was achieved in 18 patients(50%)with 6 mo follow-up.Delayed cerebral ischemia and Glasgow coma scale were considered as significant predictors of outcome(2.066 and-0.296,respectively,P<0.05).CONCLUSION Ventricular intracranial pressure monitoring may effectively maintain the intracranial pressure within the normal range.Despite the small number of cases in the current work,high-grade patients may benefit from a combination therapy of early coiling and subsequent ventricular intracranial pressure monitoring.
文摘The prevalence of nasopharyngeal carcinoma(NPC) is higher in southern China, Hong Kong, and Taiwan than in other areas in the world. Radiotherapy is an important part of treatment for NPC patients, especially those with stage Ⅲ/Ⅳ disease. Subdural empyema is a rare but life-threatening complication in postradiotherapy NPC patients which should be paid more attention. Here, we present the case of a 64-year-old female postradiotherapy NPC patient with subdural empyema complicated with intracranial hemorrhage. She was treated by burr-hole surgery but unfortunately died because of recurrent intracranial hemorrhage. The mechanisms potentially underlying the formation of subdural empyema in postradiotherapy NPC patients and the surgical strategies that can be used in these patients are discussed in this report.

文摘BACKGROUND Synovial sarcoma(SS)is a highly malignant tumor of unknown histological origin.This tumor can occur in various parts of the body,including those without synovial structures,but mainly in and around the joints,mostly in the lower extremities.Primary intracranial SSs are remarkably rare.This paper aims to report a case of primary intracranial SS with hemorrhage.CASE SUMMARY A 35-year-old male patient suffered a headache and slurred speech during manual labor and was sent to the emergency department.Through imaging examination,the patient was considered to have high-grade glioma complicated with hemorrhage and was treated with craniotomy.Postoperative pathology revealed SS.positron emission tomography/computed tomography was performed,which ruled out the possibility of metastasis to the intracranial from other parts of the body.Postoperative radiotherapy was given to the patient,during which radiation necrosis occurred.Sixteen months after craniotomy,cranial magnetic resonance imaging revealed recurrence of the tumor.CONCLUSION Primary intracranial SS is a rare malignant tumor.Primary intracranial SS with hemorrhage and radiation necrosis should be carefully monitored during postoperative radiotherapy.Surgical resection of the tumor combined with postoperative radiotherapy and chemotherapy is currently used,but the prognosis is poor.
文摘Objective:To study the effect of minimally invasive intracranial hematoma drainage on inflammatory factors, serum ferritin and serum P substance in patients with hypertensive cerebral hemorrhage.Methods:92 cases of hypertensive cerebral hemorrhage patients in our hospital were selected and randomly divided into 2 groups: minimally invasive group (51 cases) and routine group (41 cases). Minimally invasive intracranial hematoma drainage was performed on the minimally invasive group. Bone flap decompression or small bone window craniotomy were used in the routine group. Tumor necrosis factorα (TNF-α), interleukin-6 (IL-6), high sensitive C reactive protein (hs-CRP) and serum protein (SF), serum substance P (SP) in the 2 groups were detected before treatment and 2 weeks after treatment.Results: The comparison of TNF-α, IL-6, hs-CRP, SP, and SF in the two groups before treatment was not statistically significant (P>0.05). TNF-α, IL-6, hs-CRP and SF in both groups after treatment significantly decreased, compared with that before treatment (P<0.01,P<0.05). TNF-α, IL-6, and SF in minimally invasive group decreased more significantly than that in routine group (P<0.01);The comparison of SP in the two groups after treatment significantly increased compared with that before treatment (P<0.01,P<0.05). SP in minimally invasive group increased more significantly than that in routine group (P<0.05).Conclusions:Compared with bone flap decompression or small bone window craniotomy, minimally invasive intracranial hematoma drainage can inhibit inflammatory reaction, reduce the degree of nerve damage and alleviate clinical symptoms more effectively.

文摘BACKGROUND: Cerebral hemorrhage can cause the imbalance of nerve function, whereas its mechanism and main impact factors are still not quite clear. OBJECTIVE: To explore the rules about the changes of intracranial pressure in brainstem hemorrhage and internal capsule hemorrhage, and analyze the role of intracranial hypertension in the changes of nerve function caused by cerebral hemorrhage. DESIGN: A self-controlled trial. SETTING: Department of Physiology, Tianjin Medical University. MATERIALS: Sixty-five healthy male Japanese white rabbits with long ears (1.5-1.8 kg) were supplied and fed by the Department of Animal Experiment of Tianjin Medical University. The RM6240B biological signal collecting and processing system was used. METHODS: The experiments were conducted in the Department of Physiology, Tianjin Medical University from August 2001 to May 2006. ① The rabbits were anesthetized, then fixed onto the brain stereotaxic apparatus, and afterwards fenestration on skull and intubation to lateral ventricle were performed.The dynamic changes of intracranial pressure were monitored continuously. Rabbits were infused with autologous arterial blood (0.3 mL) into midbrain corpora quadrigemina inferior colliculus to induce model of acute brainstem hemorrhage; models of internal capsule hemorrhage were established by infusing autologous arterial blood into internal capsule. ② The dynamic intracranial pressures under the above conditions were recorded continuously with the RM6240B biological signal collecting and processing system. ③ An animal model of persistent intracranial hypertension was established by infusion of physiologic saline into lateral ventricle. ④ The changes of the intensity of autonomic nerve discharge were analyzed, using the biological signal collecting and processing system before and after hemorrhage and under persistent intracranial hypertension.⑤ Ten animal models of internal capsule hemorrhage and 10 of bminstem hemorrhage were selected respectively, then gross pathological samples were cut open, and the accuracy of hemorrhage models was affirmed. Histological sections in hemorrhage point and around this point were prepared for with hernatoxylin and eosin staining, and the pathological changes were observed under light microscope. MAIN OUTCOME MEASURES: ① Changes of intracranial pressures before and after internal capsule hemorrhage and brainstem hemorrhage; ②Changes of the discharge intensity of cervical vagus nerve trunk in animal models of internal capsule hemorrhage, brainstem hemorrhage and persistent intracranial hypertension without hemorrhage; ③ Accuracy of location of internal capsule hemorrhage and brainstem hemorrhage confirmed by gross pathological samples and sections. RESULTS: Totally 65 rabbits were involved in the analysis of results. ① Dynamic state of intracranial pressure: Intracranial pressure increased obviously at 45 minutes after internal capsule hemorrhage and brainstem hemorrhage, the intracranial pressures were (1.31 ±0.30), (1.82±0.45) kPa, which were obviously higher than those before hemorrhage [(1,04±0.18), (1.05±0.19) kPa, P 〈 0.01]. ② Discharge of vagus nerve: Under intracranial hypertension, the discharge of cervical vagus nerve trunk was enhanced, and the discharge intensity of vagus nerve trunk was significantly different before and after persistent intracranial hypertension [(364.28±78.55), (1252.19±151.75)μ V·s, P 〈 0.01]. The discharges of cervical vagus nerve trunk were significantly enhanced after internal capsule hemorrhage and brainstem hemorrhage (P 〈 0.01). ③ Validation of hemorrhage sites: The hemorrhage sites were internal capsule and brainstem on histopathological sections. CONCLUSION: Intracranial pressure may play an important role in the pathophysiological process of vagus nerve imbalance caused by cerebral hemorrhage.
文摘Treatment with bevacizumab,an antiangiogenic agent,in patients with metastatic or unresectable colorectal cancer was approved less than 4 years ago in Japan.Bevacizumab improves the survival of patients with metastatic colorectal cancer;however,it may lead to complications such as bleeding,which are sometimes fatal.Bevacizumab should be administered only after careful consideration because the potential risks of therapy outweigh its benefits.Therefore,pharma-ceutical companies do not recommend bevacizumab therapy for patients with brain metastases.While some reports support the cautious use of bevacizumab,others report that it is not always necessary to prohibit its use in patients with metastases to the central nervous system(CNS),including the brain.Thus,bevacizumab therapy in colorectal cancer patients with brain metastases is controversial,and it is unclear whether brainmetastases are a risk factor for intracranial hemor-rhage during anti-vascular endothelial growth factor(VEGF)therapy.We report a 64-year-old man and a 65-year-old man with recurrent colorectal cancer with-out brain metastases;these patients developed multifocal and solitary intracranial hemorrhage,respectively,after the administration of bevacizumab.Our findings suggest that intracranial hemorrhage can occur even if the patient does not have brain metastases prior to bevacizumab treatment and also suggest that brain metastases are not a risk factor for intracranial hemor-rhage with bevacizumab treatment.These findings also question the necessity of excluding patients with brain metastases from clinical trials on anti-VEGF therapy.

文摘BACKGROUND Delayed intracranial hemorrhage(DICH),a potential complication of ventriculoperitoneal(VP)shunts,has been associated with high mortality,but its risk factors are still unclear.AIM To investigate the risk factors of DICH after VP shunts.METHODS We compared the demographic and clinical characteristics of DICH and non-DICH adult patients with VP shunts between January 2016 and December 2020.RESULTS The 159 adult VP shunt patients were divided into 2 groups according to the development of DICH:the DICH group(n=26)and the non-DICH group(n=133).No statistically significant difference was found in age,sex,laboratory examination characteristics or preoperative modified Rankin Scale(mRS)score between the DICH and non-DICH groups(P>0.05);however,a history of an external ventricular drain(EVD)[P=0.045;odds ratio(OR):2.814;95%CI:1.024-7.730]and postoperative brain edema around the catheter(P<0.01;OR:8.397;95%CI:3.043-23.171)were associated with a high risk of DICH.A comparison of preoperative mRS scores between the DICH group and the non-DICH group showed no significant difference(P=0.553),while a significant difference was found in the postoperative mRS scores at the 3-mo follow-up visit(P=0.024).CONCLUSION A history of EVD and postoperative brain edema around the catheter are independent risk factors for DICH in VP shunt patients.DICH patients with a high mRS score are vulnerable to poor clinical outcomes.
文摘The thrombocytopenia-absent radius (TAR) syndrome is an autosomal recessive disease characterized by bilateral absence of radius with the presence of both thumbs and thrombocytopenia, many times associated with cardiac anomalies, intolerance or allergy to cow’s milk and phocomelia. Imaging study is important for the correct diagnosis at birth and documentation of one of the diagnosis criteria (absence of radius) in prenatal care. The main hematologic symptoms and the most feared of them, intracranial bleeding, occurs when platelets levels are below 10,000/mm<sup>3</sup>, which is more common during the first months. Therefore, imaging study is crucial to quickly identify complications and correctly manage the case. In this case report, the patient had upper limps alterations at birth and at first week presented seizures, with transfontanellar ultrasound and head computed tomography without contrast demonstrating intracranial hemorrhage. Laboratory results and imaging review were able to diagnose TAR syndrome. The patient was treated with platelets transfusion and thrombocytopenia was solved. She is currently under specialized medical care, with no neurological deficits and showing satisfactory development.
文摘BACKGROUND: Delayed vitamin K deficiency is characterized by acute onset, severe illness and high fatality rate. 33%-50% survivors accompany with other various nervous system sequelas. Therefore, diagnosis and treatment of intracranial hemorrhage in time become a key factor for improving healing rate and reducing fatality rate and incidence of sequela. OBJECTIVE: To investigate the clinical situation, experimental characteristics, CT examination and terminative characteristics of infants with intracranial hemorrhage induced by delayed vitamin K deficiency. DESIGN: Case analysis. SETTING: Department of Pediatrics, Zhongshan Hospital Affiliated to Xiamen University. PARTICIPANTS: A total of 17 infants with intracranial hemorrhage induced by delayed vitamin K deficiency aged 1-3 months including 11 boys and 6 girls were selected from Department of Pediatrics, Zhongshan Hospital Affiliated to Xiamen University from January 1994 to December 2005. All infants had drowsiness, rejective milk, spiting milk, gaze of both eyes, tic, coma, full anterior fontanelle, high muscular tension and cerebral hernia, etc. Experimental examination demonstrated that infants had anemia at various degrees; prothrombin time and partial thromboplastin time were prolonged; platelet count was normal. CT examination indicated that screenages of subarachnoid hemorrhage, subdural hematoma, cerebral parenchyma hemorrhage and intraventricular hemorrage were changed. Hemorrhage was stopped by the application of vitamin K. All patients provided informed consent. METHODS: ① Clinical situation and physical sign of infants were observed after hospitalization and scanned with rapid spiral CT scanning system. The thickness and average space of layers were 8-10 mm and the scanning time was 5 s with window width of 30-80 Hu and window position of 28-35 Hu. ② After hospitalization, four items of blood coagulation was measured with Futura meter and biochemical indexes of blood, such as serum calcium, serum alkaline phosphatase, total bilirubin, direct bilirubin and indirect bilirubin, were detected with Roche Modular PPI automatic biochemistry analyzer. ③ After hospitalization, infants were given 5-10 mg vitamin K1 for 3-5 days, and then, they were transfused with 10-15 mL/kg fresh plasma or whole blood for 1-3 times and received other relative therapies. Therapeutic effects were evaluated based on clinical diagnosis and criteria. MAIN OUTCOME MEASURES: ① Clinical situation, physical sign and CT examination; ② results of experimental examination; ③ treatment and termination. RESULTS: A total of 17 infants with intracranial hemorrhage were involved in the final analysis. ① Clinical situation, physical sign and CT examination: All infants had pale facial expression and full or bossing anterior fontanelle. Among them, 13 infants had drowsiness or dysphoria, 12 rejective milk or emesis, 11 tic, 13 injection site hemorrhage, 2 gastrointestinal hemorrhage, 3 cerebral hernia, 11 high muscular tension and 6 cervical rigidity. CT examination demonstrated that most infants (88%, 15/17) had subarachnoid hemorrhage; 10 (59%, 10/17) had subdural hematoma; 8 (47%, 8/17) had cerebral parenchyma hemorrhage; few had intraventricular hemorrhage. In addition, results of CT examination also indicated that 17 infants had intracranial hemorrhage. Hemorrhage sites of 12 infants were equal to or more than 2, which was accounted for 70% (12/17); meanwhile, partial cases accompanied with a large area of focus of cerebral infarction or cerebral hypoxia-ischemia lesion. ② Results of experimental examination: There were 6 infants with elongation of prothrombin time, 5 with partial elongation of prothrombin time, 4 with decrease of serum calcium (1.69-2.25 mmol/L), 3 with increase of serum alkaline phosphatase, 3 with increase of total bilirubin, 3 with increase of direct bilirubin, and 3 with increase of indirect bilirubin. ③ Treatment and termination: After treatment, 12 infants were cured well, 3 improved, 1 given up and 1 died. Later, ten infants received CT re-examination at 3 months after treatment. The results indicated that 3 infants had simple subarachnoid hemorrhage and 4 had subarachnoid hemorrhage accompanying with subdural hematoma. Their focuses were absorbed well and not show as obvious sequela. One infant had subdural hematoma accompanying with subarachnoid hemorrhage, cerebral parenchyma hemorrhage, intraventricular hemorrage and cerebral hypoxia ischemia, and then, after hematom absorption, obvious cerebral malacia focus, hydrocephalus, brain atrophy and inferior accumulating fluid of dura mater were observed; 2 had subdural hematoma accompanying with subarachnoid hemorrhage and cerebral hypoxia ischemia, and then, after bleeding absorption, brain atrophy was changed remarkably; changes of hydrocephalus were observed in one infant. CONCLUSION: ① Symptoms of pale facial expression, full or bossing anterior fontanelle, drowsiness and dysphoria are observed in infants with delayed vitamin K deficiency . ② Experimental indexes demonstrate that prothrombin time and partial prothrombin time are prolonged, and numbers of infants having decrease of serum calcium are in the third place. ③ Poly-intracranial hemorrhage is a notable characteristic of CT examination. Partial infants who have poly-intracranial hemorrhage always accompany with cerebral hypoxia-ischemia lesion or cerebral infarction. Clinical situation and prognosis of infants who have a large area of intracranial hemorrhage and cerebral hypoxia-ischemia changes are poor; however, those of infants who have simple subarachnoid hemorrhage or combination of subarachnoid hemorrhage with subdural hematoma are well. ④ Effect of vitamin K on this kind of disease is well.
文摘Objective: To evaluate the assessment of intracranial hypertension and nerve injury in patients with hypertensive cerebral hemorrhage by transcranial Doppler (TCD). Methods: The patients who were hospitalized for hypertensive cerebral hemorrhage between August 2014 and February 2017 were selected as the cerebral hemorrhage group and healthy subjects who received physical examination during the same period were selected as the control group;TCD was used to determine the PI of affected-side and unaffected-side middle cerebral artery in cerebral hemorrhage group and lumbar puncture was done to measure intracranial pressure. The serum was collected from the two groups to detect the levels of inflammatory cytokines and nerve injury markers. Results: PI level in affected-side middle cerebral artery of cerebral hemorrhage group was significantly higher than that in the unaffected-side and positively correlated with intracranial pressure level;serum IL-1β, TNF-α, ICAM-1, MMP9, YKL-40, Asp, Glu, NPY, NSE and GFAP levels of cerebral hemorrhage group were significantly higher than those of control group, and serum IL-1β, TNF-α, ICAM-1, MMP9, YKL-40, Asp, Glu, NPY, NSE and GFAP levels of cerebral hemorrhage group of patients with high PI level were significantly higher than those of cerebral hemorrhage group of patients with low PI level. Conclusion: TCD parameters can evaluate the degree of intracranial pressure increase and nerve injury in patients with hypertensive cerebral hemorrhage.
文摘Objective:To explore the therapeutic effect of minimally invasive intracranial hematoma evacuation in the treatment of hypertensive cerebral hemorrhage and the value of dynamic TCD monitoring in predicting the neurological function recovery.Methods: A total of 70 patients with hypertensive cerebral hemorrhage who were admitted in our hospital were included in the study and divided into the minimally invasive group and conservative group with 35 cases in each group according to different treatment protocols. The patients in the two groups were given drug conservative treatments. On this basis, the patients in the minimally invasive group were given urokinase in combined with minimally invasive hematoma puncture with YL-1 type needle. TCD was performed before treatment, 1 d, 5 d, 10 d, and 21 d after treatment. The hematoma and edema volume was calculated. NIHSS was used to evaluate the neurological function recovery.Results: Vs, Vd, and Vm after treatment in the minimally invasive group were significantly elevated, while PI was significantly reduced. Vs, Vd, and Vm after treatment in the conservative group were reduced first and elevated later, while PI was elevated first and reduced later, and reached the lowest/peak 10d after treatment. Vs, Vd, and Vm 5 d, 10 d, and 21 d after treatment in the minimally invasive group were significantly higher than those in the conservative group, while PI was significantly lower than that in the conservative group. The hematoma and edema volume after treatment in the two groups was significantly reduced. The hematoma and edema volume at each timing point was significantly lower than that in the conservative group. NIHSS score after treatment in the minimally invasive group was significantly reduced. NIHSS score in the conservative group was elevated first and reduced later, reached the peak 10d after treatment, and at each timing point was higher than that in the minimally invasive group.Conclusions:The early minimally invasive operation can significantly improve the hematoma adjacent blood flow volume in patients with hypertensive cerebral hemorrhage, and contribute to the neurological function recovery. TCD not only can be applied in the dynamic monitoring of cerebral blood flow volume in patients with hypertensive cerebral hemorrhage, but also has a certain value in evaluating the prognosis of neurological function.
