Spontaneous coronary artery rupture after lung cancer surgery:A case report and review of literature

BACKGROUND Spontaneous coronary artery rupture(SCAR)is a rare and life-threatening complication after lung cancer surgery.We present a case of SCAR following left upper lobectomy,successfully managed through emergency thoracotomy and coronary artery ligation.CASE SUMMARY A 61-year-old male patient underwent left upper lobectomy and mediastinal lymph node dissection for lung cancer.The surgery was performed using singleport video-assisted thoracoscopic surgery,and there were no observed complications during the procedure.However,19 h after surgery,the patient experienced chest discomfort and subsequently developed severe symptoms,including nausea,vomiting,and a drop in blood pressure.Urgent measures were taken,leading to the diagnosis of SCAR.The patient underwent emergency thoracotomy and coronary artery ligation,successfully stopping the bleeding and stabilizing the condition.Despite postoperative complications,the patient made a successful recovery and was discharged from the hospital.CONCLUSION SCAR is a rare but life-threatening complication following lung cancer surgery.Immediate thoracotomy has been shown to be a life-saving measure,while stenting is not the preferred initial approach.

Multi-modal imaging for the diagnosis of spontaneous visceral artery dissection:A case report

BACKGROUND Spontaneous visceral artery dissection(SVAD)is a rare condition that affects the visceral arteries,such as the celiac,superior mesenteric,and inferior mesenteric arteries,without involving the aorta.Organ ischemia or hemorrhage from vessel rupture can occur in SVAD;therefore,prompt detection and management is essential.Contrast-enhanced computed tomography(CECT)has been used to diagnose most of the previous cases,but few studies have explored the potential of contrast-enhanced ultrasound(CEUS)for early detection of this disease.CASE SUMMARY A 53-year-old male presented with complaints of poor appetite and abnormal liver function for the past 6 months.He had previously undergone transabdominal splenectomy,esophagogastric devascularization,and cholecystectomy for gallstones and severe portal hypertension.Liver ultrasound was performed in our department to assess liver status.An abnormal hepatic artery spectrum was observed,and dissection involving both the celiac artery and the common hepatic artery was observed.A CEUS was then performed and clearly showed the entry site of the intimal tear and the false lumen,and dissection was subsequently confirmed by CECT.The patient was asymptomatic;therefore,treatment to control the blood pressure was provided,and follow-up was recommended.After 6 months of follow-up,the celiac artery was found to be dilated with an adherent thrombus visible in the wall,and the common hepatic artery was occluded with the presence of collateralization.Despite these findings,no significant changes in liver function were observed.CONCLUSION Multi-modal imaging is effective in diagnosing SVAD,and conservative treatment is a choice for asymptomatic patients.

Study on Early Warning Signals of Report on Adverse Reactions of Spontaneous Reporting System of Runzao Zhiyang Capsule

Spontaneous reporting system(SRS) is an important way to monitor the adverse drug reaction(ADR) and discover the ADR signal for marketed drugs. It can detect adverse reaction signals timely and effectively, and prevent the occurrence of drug damage. Runzao Zhiyang Capsule is mainly composed of Radix Polygoni Multiflor, Radix Polygoni Multiflori Preparata, Radix Rehmanniae Recens, Radix Sophorae Flavescentis, Folium Mori and Urtica dentata Hand.-Mazz. It has the functions of nourishing blood, nourishing yin, expelling wind to relieve itching and moistening the intestines to relieve constipation. It is mainly used for skin itching, acne, constipation and other diseases caused by blood deficiency and wind dryness. The large, national SRS database of ADRs needs effective evaluation methods. We reported on the use of Bayesian confidence propagation neural network method(BCPNN) and reporting rate ratio method(PRR) with propensity score to control confounding variables. The tendency score method was used to control the hybrid bias produced by SRS data analysis. After the calculation of PRR and BCPNN, the score of "diarrhea", "rash" and "gastric dysfunction" showed that there was an early warning before and after matching. To sum up, it indicated that diarrhea, rash and gastric dysfunction were early warning signs.

Rare spontaneous intrahepatic portosystemic shunt in hepatitis Binduced cirrhosis: A case report

BACKGROUND The portosystemic shunt is the pathway between the portal vein (PV) and systemic circulation.A spontaneous intrahepatic portosystemic shunt (SPISS) is a rare portosystemic shunt type.Here we report an extremely rare type of SPISS,a spontaneous intrahepatic PV-inferior vena cava shunt (SPIVCS).CASE SUMMARY A 66-year-old woman was admitted to our hospital with the complaint of abdominal distention and a decreased appetite for 1 mo.The patient had a 20- year history of hepatitis B surface antigen positivity and a 5-year history of cirrhosis.She had been treated with Chinese herbal medicine for a long time.Liver function tests showed: alanine aminotransferase,35 U/L;aspartate aminotransferase,42 U/L;serum albumin (ALB) 32.2 g/L;and serum ascites ALB gradient,25.2 g/L.Abdominal ultrasonography and enhanced computed tomography showed that the left branch of the PV was thin and occluded;the right branch of the PV was thick and showed a vermicular dilatation vein cluster in the upper pole of the right kidney that branched out and converged into the inferior vena cava from the bare area of the lower right posterior lobe of the liver.We diagnosed her with an extremely rare SPIVCS caused by portal hypertension and provided symptomatic treatment after admission.One week later,her symptoms disappeared and she was discharged.CONCLUSION SPIVCS is a rare portosystemic shunt with a clear history of cirrhosis and portal hypertension.Clarifying the type PV shunt has important clinical significance.

Patterns of adverse drug reaction reporting in Ethiopia:A database analysis of spontaneous reports from 2013 to 2018

Objective:To examine the frequency and profile of spontaneous reports of adverse drug reactions(ADRs)sent to Ethiopia's pharmacovigilance(PV)database system.Methods:The descriptive and retrospective study analysed spontaneous ADR complaints reported to the PV database by healthcare professionals between 2013 and 2018.Spontaneous ADR reports that reached the PV center and met the minimum reporting criteria were identified and assessed in terms of reporting rate,patient characteristics,type of ADRs,suspected drugs,report sources,and reporters’profession.Results:A total of 657 spontaneous ADR reports were filed to the PV center between 2013 and 2018.During the study period,the reporting pattern of ADRs changed dramatically.The number of reports increased from 2013(n=12)and peaked in 2015(n=205),and then declined from 2016 to 2018(n=144,142 and 65 in 2016,2017 and 2018,respectively).Females had a higher percentage of reported cases(56.3%)than males(43.7%).The highest number of ADRs was reported in the age categories of 15-64 years(475,72.3%),followed by 0-14 years(154,23.4%),and 65 years and above(21,3.2%).Pharmacists reported the majority of ADRs(81.7%),followed by health officers(7.2%),nurses(5.8%),and physicians(5.2%).Skin and subcutaneous tissue abnormalities were the most commonly reported ADRs.The anatomical therapeutic chemicals code class"anti-infective for systemic use"was the most usually suspected medication.Trimethoprim with sulfamethoxazole as a combination ADRs was the most commonly reported drug that cause ADRs(14.2%).Conclusions:The number of ADRs reported in Ethiopia was small and unpredictable compared to developed countries,indicating the performance of PV system and level of awareness of health care professionals towards ADR reporting was not satisfactory.In order to increase the frequency of spontaneous reports,more efficient PV methods and public policies must be implemented.

Simultaneous embolization of a spontaneous porto-systemic shunt and intrahepatic arterioportal fistula:A case report

BACKGROUND Hepatic encephalopathy(HE)is a frequent and debilitating complication of chronic liver disease.Recurrent HE is strongly linked with spontaneous portosystemic shunts(SPSSs).Intrahepatic arterioportal fistulas(IAPFs)occur rarely but pose a major clinical challenge and may lead to or worsen portal hypertension.Herein,we present a rare case of recurrent HE secondary to a SPSS combined with an IAPF.CASE SUMMARY A 63-year-old female with primary biliary cirrhosis presented with recurrent disturbance of consciousness for 4 mo.SPSS communicating the superior mesenteric vein with the inferior vena cava and IAPF linking the intrahepatic artery with the portal vein were found on contrast-enhanced abdominal computed tomography.The patient did not respond well to medical treatment.Therefore,simultaneous embolization of SPSS and IAPF was scheduled.After embolization,the symptoms of HE showed obvious resolution.CONCLUSION The presence of liver vascular disorders should not be neglected in patients with chronic liver disease,and interventional therapy is a reasonable choice in such patients.

Spontaneous fracture of a titanium mesh cranioplasty implant in a child: A case report

BACKGROUND Titanium mesh cranioplasty is often performed after decompressive craniectomy.Spontaneous fracture of the titanium prosthesis is an extremely rare postoperative complication.Here,we report a 10-year-old boy who presented with a spontaneous fracture of titanium mesh without antecedent head trauma.CASE SUMMARY A 10-year-old boy presented with a 1-wk history of a tender bulge over the left temporo-parieto-occipital scalp.He had undergone a temporo-parieto-occipital titanium mesh cranioplasty 26 mo previously.He denied antecedent head trauma.Computerized tomography disclosed a perpendicular fissure in the titanium mesh,suggesting a diagnosis of spontaneous titanium mesh fracture.He underwent a second temporo-parieto-occipital cranioplasty and made an uneventful recovery.Three-dimensional modeling and finite element analyses were used to explore potential risk factors of titanium mesh fracture.CONCLUSION We report a case of spontaneous fracture of a titanium mesh cranioplasty implant.The current case and literature review indicate that titanium mesh implants should be well-anchored to the base of bony defects to prevent fatigue-induced fractures.

Spontaneous gastric hematoma as a rare cause of acute abdomen:A case report

BACKGROUND Spontaneous gastric hematoma is an exceedingly rare condition characterized by the accumulation of blood within the gastric wall without any apparent iatrogenic or traumatic cause.Coagulopathies are the most frequent cause of gastric he-matomas.However,other causes include amyloidosis,pancreatitis,visceral vas-cular aneurysms,endoscopy complications and others.The pathophysiology of spontaneous gastric hematoma is not completely understood.However,it is postulated that it is caused by disruption of submucosal vessels that leads to dissection of the muscularis layer and formation of false lumen.The rarity of this condition increases the challenge of diagnosis,and there is no standard treatment protocol.CASE SUMMARY We present the case of a spontaneous gastric hematoma in a 22-year-old male.He presented to our emergency department complaining of pain in the left flank area lasting for 2 wk.There was no history of trauma,antico-agulant medications or endoscopy procedures.His hemoglobin and hematocrit levels were slightly lower than normal.Multi-slice computed tomography,ultrasound and endoscopy confirmed a gastric intramural hematoma.We recommended conservative treatment because there was no hemodynamic instability nor significant bleeding.The patient responded well,and there were no unexpected events.At the 3-mo follow-up,the ultrasound exa-mination revealed complete regression of the hematoma.CONCLUSION After reviewing the literature and our experience,we recommend that more of these cases should be treated conservatively.The tendency to treat these cases with potentially burdensome procedures such as total or subtotal gastrectomy should be significantly reduced.

Rare cause of cerebral venous sinus thrombosis:Spontaneous intracranial hypotension syndrome:A case report

BACKGROUND Spontaneous intracranial hypotension syndrome is a relatively uncommon neurological disorder of unknown etiology with a good prognosis.Cerebral venous sinus thrombosis is a specific type of cerebrovascular disease caused by multiple etiologies of cerebral venous sinus or vein thrombosis that obstructs cerebral venous return and is associated with impaired cerebrospinal fluid absorption;this entity is rarely seen clinically.Spontaneous intracranial hypotension syndrome is one of the causes of cerebral venous sinus thrombosis,and the probability of their combined occurrence is only 1%-2%.As such,it is easily overlooked clinically,thus increasing the difficulty of diagnosis and treatment.CASE SUMMARY A 29-year-old young woman presented with postural headache.Lumbar puncture suggested a pressure of 50 mmH2O(normal 80 mmH2O-180 mmH2O),and magnetic resonance imaging cerebral venography suggested thrombosis of the supratentorial sinus.These findings were considered indicative of cerebral venous sinus thrombosis due to spontaneous intracranial hypotension syndrome after ruling out immunological causes,tumor,infection,abnormal coagulation mechanism,and hypercoagulable state,etc.She was treated with rehydration and low-molecular heparin anticoagulation for 15 d,and follow-up magnetic resonance imaging cerebral venography suggested resolution of the thrombus.The patient had complete improvement of her headache symptoms.CONCLUSION Spontaneous intracranial hypotension syndrome is one of the rare causes of cerebral venous sinus thrombosis,which is frequently misdiagnosed or missed and deserves consideration by clinicians during differential diagnosis.Dehydration should be avoided in such patients,and early rehydration and anticoagulation therapy are effective treatment options.

Spontaneous Bilateral Pneumothorax in a Healthy Young Adult: A Comprehensive Case Report

Background: Spontaneous bilateral pneumothorax in healthy young adults is a rare and challenging condition that defies conventional diagnostic and etiological paradigms. This case report explores the presentation, diagnostic evaluation, management, and potential contributing factors in a 29-year-old male with no prior medical history who experienced bilateral spontaneous pneumothoraces. Aim: This case report aims to shed light on the complexities of managing spontaneous bilateral pneumothorax, particularly in the absence of common risk factors. It underscores the need for a thorough assessment and ongoing research to unravel the enigma surrounding this condition. Case Presentation: A healthy 29-year-old male presented with acute chest pain and shortness of breath, ultimately diagnosed with bilateral spontaneous pneumothoraces. Despite the absence of typical risk factors, advanced imaging techniques revealed valuable insights into the diagnosis and management of this unique presentation. Conclusion: Spontaneous bilateral pneumothorax in healthy individuals presents diagnostic challenges and raises questions about potential genetic predisposition, connective tissue disorders, and lifestyle-related triggers. While the acute phase was effectively managed, this case underscores the importance of interdisciplinary collaboration and ongoing research to comprehensively understand this condition.

Pancreatic cavernous hemangioma complicated with chronic intracapsular spontaneous hemorrhage:A case report and review of literature

BACKGROUND Pancreatic cavernous hemangioma(pCH)is a rare type of benign vascular tumor.Making the right diagnosis is challenging due to low clinical suspicion and the lack of existing cross-sectional imaging tools to distinguish it from other pancreatic lesions.CASE SUMMARY We describe a male patient,age 18,who presented with a pCH.Computed tomography,magnetic resonance imaging,and ultrasound showed cystic space in the tail of the pancreas.A dark spot sign on the T2 weighted image sequence was observed.Clinically,a mucinous cystic neoplasm with hemorrhage was suspected preoperatively by combining imaging,and the operative indication was clear.The patient underwent a distal pancreatic tumor resection under laparoscopic control.Immunohistochemical staining for CD31 and CD34 was positive;D2-40 was positive in interstitial lymphatic vessels and negative in vascular epithelial cells;and calcium-binding protein was negative.The results support the diagnosis of pCH combined with chronic intracapsular spontaneous hemorrhage.No complications or recurrences were observed during the follow-up period.CONCLUSION Chronic spontaneous hemorrhage may occur in pCH,which may greatly influence the accuracy of diagnosis using imaging modalities.Surgical resection for uncertain pCH seems reasonable with a good outcome.

433例非甾体抗炎药物不良反应报告分析

目的通过对非甾体抗炎药物(NSAIDs)致药品不良反应(ADRs)进行分析,了解NSAIDs致ADRs发生特点,为临床合理安全用药作参考。方法收集2022年10月1日至2023年9月30日,国家药品不良反应监测系统接收的济南市范围内的所有NSAIDs相关ADRs报告,共计535例;剔除药品等相关信息不详报告,最终433例纳入统计分析,对报告一般情况、性别和年龄、NSAIDs类别、ADR发生时间、给药途径以及ADRs累及系统/器官和临床表现等进行统计分析。结果NSAIDs所致ADRs患者中,一般报告379例;严重ADR报告54例,转归情况大部分为痊愈或好转;男女性别比为1∶1.23,多发生于≥60岁人群(66.7%);NSAIDs涉及乙酸类(24.2%)、丙酸类(22.2%)、甲酸类(21.5%)等十大类别:ADRs发生时间≤1天(264例,61.0%);给药途径以口服(256例,59.1%)和静脉(133例,30.7%)为主。433例ADRs报告中累及多个系统/器官,共计551例次,其中排名前3位分别为胃肠系统(310,56.3%)、皮肤及其附件(122,22.1%)和视觉障碍(25,8.7%);54例严重报告累及多个系统/器官共计76例次,主要累及皮肤及其附件系统(40,52.6%)、胃肠系统(14,18.4%)和泌尿系统(4,5.3%),临床表现主要以皮疹、瘙痒、呕吐等为主。结论NSAIDs在临床上使用广泛,会导致不同程度ADRs,临床中应合理用药,确保用药安全。

Vomiting-induced pharyngeal perforation during bowel preparation for colonoscopy:A case report

BACKGROUND Effective bowel cleansing is essential for a successful colonoscopy.Laxatives,such as polyethylene glycol,are commonly used for bowel preparation.Vomiting is a frequent complication during bowel preparation,and forceful vomiting can potentially lead to esophageal perforation,as reported in several previous cases.However,pharyngeal perforation during bowel preparation has not been previously documented.Here,we present a case of pharyngeal perforation induced by forceful vomiting during bowel preparation.CASE SUMMARY A 38-year-old man with a history of hypertension,dyslipidemia,diabetes mellitus,and end-stage renal disease on hemodialysis was admitted for evaluation of recurrent abdominal pain.The patient complained of sudden pain in the neck,throat,and anterior chest following forceful vomiting during bowel preparation.Physical examination revealed crepitus under the skin of the neck and anterior chest on palpation,and upper gastrointestinal endoscopy revealed pharyngeal perforation.The perforation site was located above the upper esophageal sphincter,which distinguished it from Boerhaave’s syndrome.Conservative medical management was chosen after consultation with a thoracic surgeon and an otolaryngologist,considering the patient's mild symptoms,stable vital signs,and the small size of the lesion;the perforation resolved without endoscopic or surgical intervention.The patient was discharged from hospital two weeks after the perforation.CONCLUSION Despite its rarity,pharyngeal perforation should be considered a potential complication of bowel preparation for colonoscopy.

Subarachnoid hemorrhage misdiagnosed as acute coronary syndrome leading to catastrophic neurologic injury: A case report

BACKGROUND Elevated levels of cardiac troponin and abnormal electrocardiogram changes are the primary basis for clinical diagnosis of acute coronary syndrome(ACS).Troponin levels in ACS patients can often be more than 50 times the upper reference limit.Some patients with subarachnoid hemorrhage(SAH)also show electrocardiogram abnormalities,myocardial damage,and elevated cardiac biomarkers.Unlike ACS patients,patients with SAH only have a slight increase in troponin,and the use of anticoagulants or antiplatelet drugs is prohibited.Because of the opposite treatment modalities,it is essential for clinicians to distinguish between SAH and ACS.CASE SUMMARY A 56-year-old female patient was admitted to the emergency department at night with a sudden onset of severe back pain.The final diagnosis was intraspinal hematoma in the thoracic spine.We performed an emergency thoracic spinal canal hematoma evacuation procedure with the assistance of a microscope.Intraoperatively,diffuse hematoma formation was found in the T7-T10 spinal canal,and no obvious spinal vascular malformation changes were observed.Postoperative head and spinal magnetic resonance imaging(MRI)showed a small amount of SAH in the skull,no obvious abnormalities in the cervical and thoracic spinal canals,and no abnormal signals in the lumbar spinal canal.Thoracoab-dominal aorta computed tomography angiography showed no vascular malfor-mation.Postoperative motor system examination showed Medical Research Council Scale grade 1/5 strength in both lower extremities,and the patient experienced decreased sensation below the T12 rib margin and reported a Visual Analog Scale score of 3.CONCLUSION Extremely elevated troponin levels(more than 50 times the normal range)are not unique to coronary artery disease.SAH can also result in extremely high troponin levels,and antiplatelet drugs are contraindicated in such cases.Emergency MRI can help in the early differential diagnosis,as a misdiagnosis of ACS can lead to catastrophic neurological damage in patients with spontaneous spinal SAH.

Acquired factor XIII deficiency presenting with multiple intracranial hemorrhages and right hip hematoma:A case report

BACKGROUND Factor XIII(FXIII)deficiency is a rare yet profound coagulopathy.FXIII plays a pivotal role in hemostasis,and deficiencies in this factor can precipitate unchecked or spontaneous hemorrhaging.Immunological assays for detecting FXIII inhibitors are indispensable for diagnosing acquired FXIII deficiency;however,the availability of suitable testing facilities is limited,resulting in prolonged turnaround times for these assays.CASE SUMMARY In this case study,a 53-year-old male devoid of significant medical history presented with recurrent intracranial hemorrhages and a hematoma in the right hip.Subsequent genetic analysis revealed a homozygous mutation in the ACE gene,confirming the diagnosis of acquired FXIII deficiency.CONCLUSION This case underscores the significance of considering acquired deficiencies in clotting factors when evaluating patients with unexplained bleeding episodes.

Giant cavernous aneurysms occluded by aneurysmal thrombosis,calcification,parent artery occlusion:A case report and review of literature

BACKGROUND Patients with giant intracranial aneurysms(GIAs)are at a high risk of rupture,morbidity,and mortality even after surgical or endovascular treatment.We described a case of a spontaneously occluded GIA secondary to gradual growth of the GIA,continuously progressed aneurysmal thrombosis,complete aneurysmal calcification and complete occlusion of the parent artery-the right internal carotid artery(RICA).CASE SUMMARY A 72-year-old female patient complained of sudden pain in her right eye upon admission to our hospital.She had been diagnosed with a GIA[30 mm(axial)×38 mm(coronal)×28 mm(sagittal)]containing an aneurysmal thrombus located in the cavernous sinus segment of RICA diagnosed by magnetic resonance imaging(MRI),enhanced MRI,and magnetic resonance angiography more than 14 years ago.Later,with slow growth of the cavernous carotid GIA,aneurysmal thrombosis progressed continuously,spontaneous occlusion of the RICA,complete aneurysmal calcification,and occlusion of the GIA occurred gradually.She had no history of subarachnoid hemorrhage but missed the chance for endovascular therapy at an early stage.As a result,she was left with severe permanent sequelae from the injuries to the right cranial nerves Ⅱ,Ⅲ,Ⅳ,V1/V2,and Ⅴ.CONCLUSION The risk of rupture of the cavernous carotid GIAs was relatively low and possibly further be reduced by the stasis flow and spontaneous occlusion of the parent artery internal carotid artery(ICA)induced by the mass effect of the cavernous carotid GIAs and the extremely rare aneurysmal calcification.However,nowadays,it is advisable to recommend early endovascular treatment for the cavernous carotid GIAs to prevent injuries to the surrounding intracranial nerves and occlusion of the ICA,mainly caused by the mass effect of the cavernous carotid GIAs.

Klebsiella pneumoniae infection secondary to spontaneous renal rupture that presents only as fever:A case report

BACKGROUND Spontaneous renal rupture is a rare disease in the clinic.The causes of spontaneous renal rupture include extrarenal factors,intrarenal factors,and idiopathic factors.Reports on infection secondary to spontaneous renal rupture and the complications of spontaneous renal rupture are scarce.Furthermore,there are few patients with spontaneous renal rupture who present only with fever.CASE SUMMARY We present the case of a 52-year-old female patient who was admitted to our hospital.She presented only with fever,and the cause of the disease was unclear.She underwent a contrast-enhanced computed tomography(CT)scan,which showed that the left renal capsule had a crescent-shaped,low-density shadow;the perirenal fat was blurred,and exudation was visible with no sign of calculi,malignancies,instrumentation,or trauma.Under ultrasound guidance,a pigtail catheter was inserted into the hematoma,and fluid was drained and used for the bacterial test,which proved the presence of Klebsiella pneumoniae.Two months later,abdominal CT showed that the hematoma was absorbed,so the drainage tube was removed.The abdominal CT was normal after 4 mo.CONCLUSION Spontaneous renal rupture due to intrarenal factors causes a higher proportion of shock and is more likely to cause anemia.

Spontaneous superior mesenteric artery dissection following upper gastrointestinal panendoscopy: A case report and literature review

BACKGROUND Complications associated with upper gastrointestinal(UGI)endoscopy are uncommon,and rarely involve those of cardiovascular nature.We report herein a unique case of spontaneous superior mesenteric artery dissection(SMAD)after UGI pandenoscopy.CASE SUMMARY A 45-year-old man who had previously undergone UGI panendoscopy and colonoscopy during a voluntary health check-up at our facility was admitted to the emergency room(ER)at the same facility due to persistent epigastric pain with radiation to the back.At the ER,the patient did not present notable abnormalities upon physical,conscious,or laboratory examinations apart from mild tenderness in the epigastric abdomen.Acute abdominal aortic dissection was suspected,and abdominal contrast-enhanced computed tomography confirmed SMAD.He was then transferred to the cardiovascular ward and treated conservatively with fasting,prostaglandin E1,and aspirin.The patient recovered and returned home soon after,and was symptom-free 6 months after discharge from the facility.CONCLUSION SMAD after UGI panendoscopic procedure is a previously unreported complication.Awareness of this complication and associated sequela is warranted.

Rapid spontaneous resolution of lumbar ganglion cysts: A case report

BACKGROUND To discuss the rare event of spontaneous resolution of a lumbar ganglion cyst,a personal case report and 25 cases culled from the literature were described in detail.We focused on demographic,classification,clinical and radiological findings,treatment,outcome and radiological resolution.CASE SUMMARY A 51-year-old man presented to our observation with complaints of low back and right leg pain.Lumbar magnetic resonance imaging(MRI).showed a L4-L5 ganglion cyst.The patient was referred to medical therapy and bracing.After 4 wk,he showed a complete resolution of pain.The complete spontaneous resolution of the cyst was demonstrated by the followed-up MRI.CONCLUSION Spontaneous resolution of lumbar ganglion is very rare and only 26 cases,including ours,were reported in literature.Different degrees of biomechanical impairment seem to play a fundamental role in the pathogenesis.Related symptoms are essentially represented by low back and/or radicular pain,without significant neurological disorders.Anti-inflammatory drugs,light unloading exercises and brace could be recommended to administrated pain and decrease facet loads.Mean time for clinical improvement was 7 mo,while MRI disappearance occurred in an average time of 11 mo.Therefore,surgery should be applied when conservative treatment,prolonged at least 6 mo,fails.
