A nonsense mutation from C to T on locus 6431 in exon 3B of the antithrombin gene was observed, leading to an arginine (CGA) to stop codon (TGA) change in the protein. This is the first report of this mutation in China. Ineffective heparin therapy in the propositus patient is associated with a lack of heparin binding sites after antithrombin gene mutation. Characteristic low intracranial pressure in the acute phase might be specific to this patient with cerebral venous sinus thrombosis.展开更多

The establishment of an animal model that imitates the clinical pathophysiological processes is crucial to better study this disease during a certain time window. OBJECTIVE: To establish a new animal model of dural venous sinus embolism that is simple, has a high success rate, and emulates the pathophysiological course of clinical disease. DESIGN, TIME AND SETTING: A randomized block design trial was performed at the Department of Anatomy, Ningxia Medical College between March and December 2007. MATERIALS: Fifty-eight healthy, adult, Sprague Dawley rats were used in the present study. Plastic emboli, with a total length of 0.4 cm, were self-made. Each plastic embolus had a conical anterior segment; the largest diameter being 0.12 cm. The posterior segment became gradually thin and flat, with a width of 0.2 cm and length of 0.1 cm. METHODS: The fifty-eight rats were randomly divided into three groups: control (n = 6), embolism (n = 26), and sham-embolism (n = 26) groups. In the embolism group, a solid embolus was slowly inserted and fixed into the posterior part of the superior sagittal sinus against the flow of blood. The posterior segment was detained outside the superior sagittal sinus for fixing. In the sham-embolism group, rats were subjected only to sinus sagittalis superior exposure. In the control group, rats received no treatments. In both the embolism and the sham-embolism groups, the rat brains were resected at 6 hours, 1, 3, and 5 days post-surgery. MAIN OUTCOME MEASURES: (1) Brain surface appearance in the embolism and sham-embolism groups. (2) Thrombosis in the embolism group. (3) Cerebrospinal fluid content in the above-mentioned two groups. RESULTS: In the embolism group, the model success rate was 92% (24/26). There was visible thrombosis in the superior sagittal sinus. Cerebral edema was noticeable under a microscope. These changes were visible at 6 hours after embolism and were most obvious at 1 day after surgery. In the embolism group, cerebrospinal fluid content reached a peak level at 6 hours post-surgery and was significantly increased compared with the sham-embolism and the control groups (P 〈 0.05). At 1 day post-surgery, the amount of cerebrospinal fluid was still greater in the embolism group compared to the control group (P 〈 0.05) CONCLUSION: The method of inserting a solid embolus has many benefits, such as being able to directly observe, short cycle time, and minimal wound. The detained posterior segment prevents movement and perfusion of embolus, which results in a high success rate.展开更多

The diagnosis of cerebral venous sinus thrombosis is challenged due to nonspecific clinical symptomatology. Patients may present at an emergency room with a variety of neurological conditions such as severe headache, weakness, seizure, etc. Neuroimaging, particularly noncontrast cranial computed tomography (NCCT), is an investigation of choice in differentiation and triage the patients for further treatment. CT is sensitive in the detection of acute thrombosis or blood clots in all regions of the body. We hypothesize that NCCT might be sensitive to diagnose cerebral venous thrombosis immediately. <strong>Materials and Methods:</strong> Retrospectively review the electronic database of our patients, there are 27 patients with cerebral sinus venous thrombosis (SVT) and 4 patients with cerebral deep venous thrombosis (DVT). Other 79 patients present with clinically diagnosed cerebral venous thrombosis but the final result can exclude cerebral venous thrombosis. We use MR imaging and CT venography as the gold standard. Independently reviewed by two neuroradiologists for CT direct sign and CT indirect signs that suggest SVT or DVT. CT direct signs for SVT and DVT are the presence of hyperdensity in the sinus venous or deep venous system (cord sign, attenuated vein sign) and CT indirect signs are the changes in brain parenchyma (brain edema, hemorrhagic infarction). <strong>Results:</strong> Sensitivity and specificity of NCCT in detection attenuated vein sign and diagnosis DVT are 75% and 100% whereas the sensitivity and specificity of NCCT in detection cord sign and diagnosis SVT are 43.8% and 99.7% as respectively. <strong>Conclusions:</strong> NCCT might not sensitive in detection of SVT without CT direct sign which needs further investigation. However, NCCT might beneficial for emergency conditions such as DVT patients, cortical vein thrombosis and also in SVT patients with the positive CT direct sign.展开更多

CVST although being a Rare disorder but may be more common in children than adults with greater risk in neonatal period i.e. first 28 days of life. Here we are discussing a case of Pediatric CVST in a 7-month-old baby boy who presented to Emergency Room (ER) with recurrent discrete episodes of vomiting, fever, seizures, drowsiness and respiratory distress. The fatal outcome in our child was attributed to delayed presentation in a tertiary care center, hence missed early diagnosis and treatment. In this child the CVST could be result of amalgamation of complex underlying ongoing multiple pathological processes: an acute systemic illness like sepsis, severe dehydration, undiagnosed and untreated complex congenital heart disease, tetralogy of fallot with osteum secondum atrial septal defect, worsening the coagulopathy. It takes this case even more unique. This discussion is to bring focus on the importance of knowledge about CVST amongst emergency physicians and primary care physicians, specially managing this rare disorder with flummox presentation mimicking other more common disorders, especially in pediatric and neonatal population where definitive history and chief complaints are often vague and difficult to obtain, making it more difficult to diagnose. We the authors hence reporting this case with intent to spread awareness of CVST, how to doubt it, detect it and then manage it, especially in places like Chhattisgarh, India, where CVST is not so uncommon. We believe early diagnosis, early presentation to tertiary care center with aggressive early treatment can significantly reduce the mortality. Should the parents brought the baby early to any tertiary care center owing to his complex deteriorating symptoms like high grade fever progressed to drowsiness and seizure episodes, could there be a different outcome for this child as well as his parents.展开更多

In our case report, we discussed a rare presentation of CVST, a 16-year-old young boy who presented in emergency with history recurrent fall, weakness, tingling numbness. What makes it challenging to diagnose in his unusual presentation without common symptoms and on examination no positive neurological finding. This case brings focus on the importance of knowledge about CVST among emergency physicians. CSVT is considered more commonly as a differential diagnosis of stroke in young age group owning to genetic predisposition, hot humid climate of the state leading to severe dehydration, dietary factors leading to vitamin B12 deficiency & hyper-homocysteinemia etc. Moreover, present COVID-19, inducing a hypercoagulable state among affected individuals gave CVST a new momentous among emergency physicians. An early diagnosis can be very fruitful as it might prevent long term disability and reduce mortality significantly.展开更多

OBJECTIVE: To observe the distribution of intracranial arachnoid granulations in rats. DESIGN, TIME AND SETTING: The observational experiment was performed in the Academy of Life Sciences of Shandong Taishan Medical College from May to August 2004. MATERIALS: Thirty healthy adult Wistar rats (3-4 months old) of SPF grade, equal numbers of each sex, were selected for this study. Methylene blue parenteral solution was provided by Jiangsu Jichuan Pharmaceutical Company (China), and an optical microscope (Type: CH20; Olympus Co. Ltd., Japan) was used for observation of the histomorphology of the arachnoid granulations. METHOD: Injection of methylene blue parenteral solution into the cerebellomedullary cistern of rats. MAIN OUTCOME MEASURE: The blue stained parts of the lateral sinus were sectioned, stained by hematoxylin and eosin, and then observed under the microscope. RESULTS: The cavitas subarachnoidealis had extensive blue staining after methylene blue injection, while the arachnoid and dura were without dye accumulation. The blue dye indicated the location of the arachnoid granulations. The location of these granulations was fixed, mainly in the lateral sinus at both sides of confluence within 4 mm of the internal jugular vein. CONCLUSION: The arachnoid granulations of the rat were located mainly in the lateral sinuses of the dura mater.展开更多

We report two cases of ...Dural enhancement detected by magnetic resonance imaging is a common finding in patients with cerebral venous sinus thrombosis (CVST) and is usually interpreted as a change secondary to CVST. We report two cases of CVST with intense and diffuse dural enhancement that resulted from pachymeningitis in one patient and spontaneous intracranial hypotension in another. Pachymeningitis and spontaneous intracranial hypotension were also determined to be the underlying causes of CVST. The clinical data of these two patients are described. In patients with CVST, dural enhancement is not always a secondary change to CVST. It can be a manifestation of the underlying causes of CVST. When diffuse and intense dural enhancement is revealed, sufficient ancillary tests are warranted to rule out other potential patholooical chanoes of the dura mater those can result in CVST.展开更多

We aimed to prospectively investigate the diagnostic accuracy of magnetic resonance venography (MRV) in the evaluation of the recanalization of CVST. Methods This study prospectively evaluated the diagnostic performance of 2-dimensional time-of-flight (2D-TOF) MRV in thirty-two consecutive patients during a threeto six-month follow-up for CVST. Both 2D-TOF MRV and digital substraction angiography (DSA) were undertaken. Diagnostic accuracy of 2D-TOF MRV in the detection of recanalized thrombus was evaluated using DSA as the reference standard. Results MRV and DSA were completed without complications in all 32 patients. The sensitivity, specificity, positive predictive value, and negative predictive value of 2D-TOF MRV for the detection of recanalization on a segmental basis were 91% (62/68), 93% (37/40), 95% (62/65), and 86% (37/43) respectively. Conclusion 2D-TOF MRV provides high sensitivity and specificity for the diagnosis of recanalized CVST segments.展开更多

Antiphospholipid syndrome (APS) is an autoimmune disease characterised by recurrent arterial or venous thrombosis, pregnancy morbidity and the persistence of positive antiphospholipid antibodies (aPL), including anticardiolipin antibody (ACL) and lupus anticoagulant (LA). 1 The most prevalent neurologic manifestation of APS is cerebrovascular ischemic events due to arterial thromboses. The deep veins of lower extremities are commonly involved in venous thrombosis of APS, but cerebral venous sinus thrombosis is rare with only several cases reported.2-11 AA together with APS is extremely rare.12 Here we report a case of cerebral venous sinus thrombosis in an AA patient with APS.展开更多

文摘This study sought to elucidate the genetic correlation of cerebral venous sinus thrombosis caused by a hereditary antithrombin deficiency in a Chinese family, at the genetic and protein levels. A nonsense mutation from C to T on locus 6431 in exon 3B of the antithrombin gene was observed, leading to an arginine (CGA) to stop codon (TGA) change in the protein. This is the first report of this mutation in China. Ineffective heparin therapy in the propositus patient is associated with a lack of heparin binding sites after antithrombin gene mutation. Characteristic low intracranial pressure in the acute phase might be specific to this patient with cerebral venous sinus thrombosis.

文摘BACKGROUND: The pathological mechanism of secondary brain lesion following an embolism remains unclear. The establishment of an animal model that imitates the clinical pathophysiological processes is crucial to better study this disease during a certain time window. OBJECTIVE: To establish a new animal model of dural venous sinus embolism that is simple, has a high success rate, and emulates the pathophysiological course of clinical disease. DESIGN, TIME AND SETTING: A randomized block design trial was performed at the Department of Anatomy, Ningxia Medical College between March and December 2007. MATERIALS: Fifty-eight healthy, adult, Sprague Dawley rats were used in the present study. Plastic emboli, with a total length of 0.4 cm, were self-made. Each plastic embolus had a conical anterior segment; the largest diameter being 0.12 cm. The posterior segment became gradually thin and flat, with a width of 0.2 cm and length of 0.1 cm. METHODS: The fifty-eight rats were randomly divided into three groups: control (n = 6), embolism (n = 26), and sham-embolism (n = 26) groups. In the embolism group, a solid embolus was slowly inserted and fixed into the posterior part of the superior sagittal sinus against the flow of blood. The posterior segment was detained outside the superior sagittal sinus for fixing. In the sham-embolism group, rats were subjected only to sinus sagittalis superior exposure. In the control group, rats received no treatments. In both the embolism and the sham-embolism groups, the rat brains were resected at 6 hours, 1, 3, and 5 days post-surgery. MAIN OUTCOME MEASURES: (1) Brain surface appearance in the embolism and sham-embolism groups. (2) Thrombosis in the embolism group. (3) Cerebrospinal fluid content in the above-mentioned two groups. RESULTS: In the embolism group, the model success rate was 92% (24/26). There was visible thrombosis in the superior sagittal sinus. Cerebral edema was noticeable under a microscope. These changes were visible at 6 hours after embolism and were most obvious at 1 day after surgery. In the embolism group, cerebrospinal fluid content reached a peak level at 6 hours post-surgery and was significantly increased compared with the sham-embolism and the control groups (P 〈 0.05). At 1 day post-surgery, the amount of cerebrospinal fluid was still greater in the embolism group compared to the control group (P 〈 0.05) CONCLUSION: The method of inserting a solid embolus has many benefits, such as being able to directly observe, short cycle time, and minimal wound. The detained posterior segment prevents movement and perfusion of embolus, which results in a high success rate.

文摘BACKGROUND Hypereosinophilia(HE)is defined as a peripheral blood eosinophil count of>1.5×109/L and may be associated with tissue damage.The clinical presentations of HE vary;however,myocardial fibrosis and thrombosis can threaten the lives of patients with sustained eosinophilia.Cerebral venous sinus thrombosis(CVST)in the setting of eosinophil-related diseases has seldom been reported.Here,we review the literature on HE with CVST to increase knowledge and encourage early diagnosis.CASE SUMMARY A previously healthy 41-year-old man was admitted to hospital with diarrhea and abdominal pain.He was treated with antibiotics for suspected acute colitis.Three days later,he experienced headache and vomiting.Brain computed tomography(CT)revealed thrombosis of the left jugular vein to the left transverse sinus vein.Platelet(PLT)count decreased to 60×1012/L,and absolute eosinophil count(AEC)increased to 2.41×109/L.He was treated with low-molecular-weight heparin.PLT count progressively decreased to 14×109/L,and we terminated anticoagulation and performed PLT transfusion.Six days after admission,he complained of a worsening headache.Brain CT revealed right temporal lobe and left centrum semiovale intracerebral hemorrhage,and AEC increased to 7.65×109/L.We used prednisolone for HE.The level of consciousness decreased,so emergency hematoma removal and decompressive craniectomy for right cerebral hemorrhage were performed.The patient was alert 2 d after surgery.He was treated with anticoagulation again 2 wk after surgery.Corticosteroids were gradually tapered without any symptomatic recurrence or abnormal laboratory findings.CONCLUSION HE can induce CVST,and we need to focus on eosinophil counts in patients with CVST.

文摘BACKGROUND The hereditary antithrombin(AT)deficiency caused by SERPINC1 gene mutation is an autosomal dominant thrombotic disorder.An increasing number of studies have shown that mutations in the SERPINC1 rs2227589 polymorphic site are correlated with a risk of venous thromboembolism(VTE)at common sites,such as lower extremity deep venous thrombosis and pulmonary thromboembolism.Currently,there are no reports of cerebral venous sinus thrombosis(CVST),a VTE site with a low incidence rate and rs2227589 polymorphism.CASE SUMMARY Here,we report a Chinese CVST case with a mutation of the SERPINC1 rs2227589 polymorphic site,which did not cause significant AT deficiency.In a 50-year-old male patient presenting with multiple cerebral venous sinus thromboses no predisposing factors were detected,although a relative had a history of lower extremity deep venous thrombosis.We performed sequencing of the SERPINC1 gene for the patient and his daughter,which revealed the same heterozygous mutation at the rs2227589 polymorphic site:c.41+141G>A.CONCLUSION The results showed that more studies should be conducted to assess the correlation between rs2227589 polymorphism and CVST.
文摘<strong>Background and Purpose</strong>: Increasing concern of cerebral venous thrombosis due to treatable and curable causes of stroke. The diagnosis of cerebral venous sinus thrombosis is challenged due to nonspecific clinical symptomatology. Patients may present at an emergency room with a variety of neurological conditions such as severe headache, weakness, seizure, etc. Neuroimaging, particularly noncontrast cranial computed tomography (NCCT), is an investigation of choice in differentiation and triage the patients for further treatment. CT is sensitive in the detection of acute thrombosis or blood clots in all regions of the body. We hypothesize that NCCT might be sensitive to diagnose cerebral venous thrombosis immediately. <strong>Materials and Methods:</strong> Retrospectively review the electronic database of our patients, there are 27 patients with cerebral sinus venous thrombosis (SVT) and 4 patients with cerebral deep venous thrombosis (DVT). Other 79 patients present with clinically diagnosed cerebral venous thrombosis but the final result can exclude cerebral venous thrombosis. We use MR imaging and CT venography as the gold standard. Independently reviewed by two neuroradiologists for CT direct sign and CT indirect signs that suggest SVT or DVT. CT direct signs for SVT and DVT are the presence of hyperdensity in the sinus venous or deep venous system (cord sign, attenuated vein sign) and CT indirect signs are the changes in brain parenchyma (brain edema, hemorrhagic infarction). <strong>Results:</strong> Sensitivity and specificity of NCCT in detection attenuated vein sign and diagnosis DVT are 75% and 100% whereas the sensitivity and specificity of NCCT in detection cord sign and diagnosis SVT are 43.8% and 99.7% as respectively. <strong>Conclusions:</strong> NCCT might not sensitive in detection of SVT without CT direct sign which needs further investigation. However, NCCT might beneficial for emergency conditions such as DVT patients, cortical vein thrombosis and also in SVT patients with the positive CT direct sign.
文摘Background:Cerebrospinal fluid(CSF)-diversion procedures have traditionally been the standard of treatment for patients with medically refractive idiopathic intracranial hypertension(IIH).However,dural venous sinus stent(VSS)placement has been described as a safe and effective procedure for the management of medically refractive IIH.We performed a meta-analysis comparing outcomes and complications of CSF-diversion procedures,VSS and optic nerve sheath fenestration(ONSF)for the treatment of medically refractive IIH.Methods:Electronic searches were performed using six databases from 1988 to January 2017.Data was extracted and meta-analysed from the identified studies.Results:From 55 pooled studies,there were 538 CSF-diversion cases,224 dural venous stent placements,and 872 ONSF procedures.Similar improvements were found in terms of postoperative headaches(CSF vs.VSS vs.ONSF:84%vs.78%vs.62%,P=0.223),papilledema(CSF vs.VSS vs.ONSF:71%vs.86%vs.77%,P=0.192),whilst visual acuity changes favored venous stenting(CSF vs.VSS vs.ONSF:55%vs.69%vs.44%,P=0.037).There was a significantly lower rate of subsequent procedures with venous stent placement(CSF vs.VSS vs.ONSF:37%vs.13%vs.18%,P<0.001),but other complication rates were similar(CSF vs.VSS vs.ONSF:13%vs.8%vs.14%,P=0.28).Subgroup analysis of lumbar-peritoneal vs.ventriculoperitoneal shunts found no differences in symptom improvements,complications and subsequent procedure rates.Conclusions:Our findings suggest that dural venous sinus stenting may be a viable alternative to traditional surgical interventions in patients who are refractory to medical treatment.
文摘Cerebral Venous Sinus Thrombosis (CVST/CSVT) is occlusion of cerebral veins and venous sinuses of brain secondary to blood clot formation resulting in hindrance in the blood drainage system in brain, leading to disturbances the internal homeostasis of brain, raised intracranial pressure, cerebral edema, and 50% of cases will have venous infarction or venous hemorrhage (stroke). CVST although being a Rare disorder but may be more common in children than adults with greater risk in neonatal period i.e. first 28 days of life. Here we are discussing a case of Pediatric CVST in a 7-month-old baby boy who presented to Emergency Room (ER) with recurrent discrete episodes of vomiting, fever, seizures, drowsiness and respiratory distress. The fatal outcome in our child was attributed to delayed presentation in a tertiary care center, hence missed early diagnosis and treatment. In this child the CVST could be result of amalgamation of complex underlying ongoing multiple pathological processes: an acute systemic illness like sepsis, severe dehydration, undiagnosed and untreated complex congenital heart disease, tetralogy of fallot with osteum secondum atrial septal defect, worsening the coagulopathy. It takes this case even more unique. This discussion is to bring focus on the importance of knowledge about CVST amongst emergency physicians and primary care physicians, specially managing this rare disorder with flummox presentation mimicking other more common disorders, especially in pediatric and neonatal population where definitive history and chief complaints are often vague and difficult to obtain, making it more difficult to diagnose. We the authors hence reporting this case with intent to spread awareness of CVST, how to doubt it, detect it and then manage it, especially in places like Chhattisgarh, India, where CVST is not so uncommon. We believe early diagnosis, early presentation to tertiary care center with aggressive early treatment can significantly reduce the mortality. Should the parents brought the baby early to any tertiary care center owing to his complex deteriorating symptoms like high grade fever progressed to drowsiness and seizure episodes, could there be a different outcome for this child as well as his parents.
文摘Cerebral Venous Sinus Thrombosis (CVST) is blood clot in draining veins and venous sinuses of brain, causing hindrance in the blood drainage system in brain, disturbing the internal homeostasis of brain, resulting in local oedema, ischemia, venous haemorrhage, damage to brain parenchyma and blood brain barrier. In our case report, we discussed a rare presentation of CVST, a 16-year-old young boy who presented in emergency with history recurrent fall, weakness, tingling numbness. What makes it challenging to diagnose in his unusual presentation without common symptoms and on examination no positive neurological finding. This case brings focus on the importance of knowledge about CVST among emergency physicians. CSVT is considered more commonly as a differential diagnosis of stroke in young age group owning to genetic predisposition, hot humid climate of the state leading to severe dehydration, dietary factors leading to vitamin B12 deficiency & hyper-homocysteinemia etc. Moreover, present COVID-19, inducing a hypercoagulable state among affected individuals gave CVST a new momentous among emergency physicians. An early diagnosis can be very fruitful as it might prevent long term disability and reduce mortality significantly.
文摘BACKGROUND: This paper describes histomorphologic studies on arachnoid granulations in rats, which have not been investigated in China to our knowledge. OBJECTIVE: To observe the distribution of intracranial arachnoid granulations in rats. DESIGN, TIME AND SETTING: The observational experiment was performed in the Academy of Life Sciences of Shandong Taishan Medical College from May to August 2004. MATERIALS: Thirty healthy adult Wistar rats (3-4 months old) of SPF grade, equal numbers of each sex, were selected for this study. Methylene blue parenteral solution was provided by Jiangsu Jichuan Pharmaceutical Company (China), and an optical microscope (Type: CH20; Olympus Co. Ltd., Japan) was used for observation of the histomorphology of the arachnoid granulations. METHOD: Injection of methylene blue parenteral solution into the cerebellomedullary cistern of rats. MAIN OUTCOME MEASURE: The blue stained parts of the lateral sinus were sectioned, stained by hematoxylin and eosin, and then observed under the microscope. RESULTS: The cavitas subarachnoidealis had extensive blue staining after methylene blue injection, while the arachnoid and dura were without dye accumulation. The blue dye indicated the location of the arachnoid granulations. The location of these granulations was fixed, mainly in the lateral sinus at both sides of confluence within 4 mm of the internal jugular vein. CONCLUSION: The arachnoid granulations of the rat were located mainly in the lateral sinuses of the dura mater.

文摘Cerebral venous sinus thrombosis(CVST)is a type of stroke associated with COVID-19 vaccine-induced immune thrombotic thrombocytopenia.The precise etiology of CVST often remains elusive due to the highly heterogeneous nature of its governing mechanisms,specifically,Virchow’s triad that involves altered blood flow,endothelial dysfunction,and hypercoagulability,which varies substantially amongst individuals.Existing diagnostic and monitoring approaches lack the capability to reflect the combination of these patient-specific thrombotic determinants.In response to this challenge,we introduce a Vein-Chip platform that recapitulates the CVST vascular anatomy from magnetic resonance venography and the associated hemodynamic flow profile using the“Chinese Movable Type-like”soft stereolithography technique.The resultant full-lumen personalized Vein-Chips,functionalized with endothelial cells,enable in-vitro thrombosis assays that can elucidate distinct thrombogenic scenarios between normal vascular conditions and those of endothelial dysfunction.The former displayed minimal platelet aggregation and negligible fibrin deposition,while the latter presented significant fibrin extrusion from platelet aggregations.The low-cost movable typing technique further enhances the potential for commercialization and broader utilization of personalized Vein-Chips in surgical labs and at-home monitoring.Future research and development in this direction will pave the way for improved management and prevention of CVST,ultimately benefiting both patients and healthcare systems.
文摘Dural enhancement detected by magnetic resonance imaging is a common finding in patients with cerebral venous sinus thrombosis (CVST) and is usually interpreted as a change secondary to CVST. We report two cases of CVST with intense and diffuse dural enhancement that resulted from pachymeningitis in one patient and spontaneous intracranial hypotension in another. Pachymeningitis and spontaneous intracranial hypotension were also determined to be the underlying causes of CVST. The clinical data of these two patients are described. In patients with CVST, dural enhancement is not always a secondary change to CVST. It can be a manifestation of the underlying causes of CVST. When diffuse and intense dural enhancement is revealed, sufficient ancillary tests are warranted to rule out other potential patholooical chanoes of the dura mater those can result in CVST.
文摘Background In the chronic stage of cerebral venous sinus thrombosis (CVST), recanalization can result in disparate MR appearances. We aimed to prospectively investigate the diagnostic accuracy of magnetic resonance venography (MRV) in the evaluation of the recanalization of CVST. Methods This study prospectively evaluated the diagnostic performance of 2-dimensional time-of-flight (2D-TOF) MRV in thirty-two consecutive patients during a threeto six-month follow-up for CVST. Both 2D-TOF MRV and digital substraction angiography (DSA) were undertaken. Diagnostic accuracy of 2D-TOF MRV in the detection of recanalized thrombus was evaluated using DSA as the reference standard. Results MRV and DSA were completed without complications in all 32 patients. The sensitivity, specificity, positive predictive value, and negative predictive value of 2D-TOF MRV for the detection of recanalization on a segmental basis were 91% (62/68), 93% (37/40), 95% (62/65), and 86% (37/43) respectively. Conclusion 2D-TOF MRV provides high sensitivity and specificity for the diagnosis of recanalized CVST segments.
文摘Aplastic anemia (AA) is an acquired disorder in which .bone marrow fails to produce or release sufficient amounts of blood cell. Antiphospholipid syndrome (APS) is an autoimmune disease characterised by recurrent arterial or venous thrombosis, pregnancy morbidity and the persistence of positive antiphospholipid antibodies (aPL), including anticardiolipin antibody (ACL) and lupus anticoagulant (LA). 1 The most prevalent neurologic manifestation of APS is cerebrovascular ischemic events due to arterial thromboses. The deep veins of lower extremities are commonly involved in venous thrombosis of APS, but cerebral venous sinus thrombosis is rare with only several cases reported.2-11 AA together with APS is extremely rare.12 Here we report a case of cerebral venous sinus thrombosis in an AA patient with APS.
文摘To describe the etiologies, clinical features and diagnosis of cerebral venous sinus thrombosis Methods We reviewed the records of 23 patients admitted with a documented diagnosis of cerebral venous sinus thrombosis from 1991 through 1999 in the Beijing Tiantan Hospital Results Infection was the major condition associated with cerebral venous sinus thrombosis Pseudotumor cerebri syndrome was the most common manifestation, while hemiplegia, seizure and unconsciousness may occur alone or in association The diagnostic sensitivity of computed tomography (CT), magnetic resonance imaging (MRI) and digital subtract angiography (DSA) were 59%, 86% and 100%, respectively The sensitivity of MRI with magnetic resonance angiography (MRA) reached 96% Conclusion As the clinical findings were found to be nonspecific, CT combined with DSA, or MRI with MRA turns out to be valuable for the early diagnosis of cerebral venous sinus thrombosis

文摘Inflammatory bowel disease(IBD)is known to increase the risk of venous thromboembolism.Cerebral venous sinus thrombosis(CVST)is a rare but important complication of IBD.Timely diagnosis,particularly in younger patients,requires a high level of suspicion in order to prevent potentially devastating complications such as hemorrhage or venous infarction.The paper presents a 44-year-old Caucasian woman with a previous history of Crohn’s disease and deep venous thrombosis.Magnetic resonance imaging confirmed the diagnosis of CVST.Achieving therapeutic anticoagulation with warfarin was difficult,due to presumed pharmacological interaction between warfarin and 6-mercaptopurine.Clinicians should have a high index of suspicion for CVST when a patient with Crohn’s disease presents with acute headache,and be aware of challenges related to medical management.
