Project description:Purpose of reviewCerebral venous thrombosis (CVT) is a rare cause of stroke that most commonly affects younger women. Here, we review new literature relevant to the management and prognosis of individuals with CVT and ongoing areas of uncertainty.Recent findingsDirect-acting oral anticoagulants (DOACs) are being increasingly integrated into routine care but are not yet recommended by guidelines. Recent randomized clinical trials and available case series offer reassuring safety data. Routine use of endovascular therapy is not associated with improved outcomes. The relationship between recanalization and prognosis is uncertain. The evidence base for management of CVT continues to improve. Ongoing areas of uncertainty include duration of therapy and whether certain subgroups of patients may benefit from neurointervention or personalized approaches to antithrombotic strategy. The state of knowledge will continue to benefit from large collaborative international efforts, and integration of patient partnerships to identify research priorities.

Project description:Spontaneous intracranial hypotension (SIH) is a well-known cause of orthostatic headache. Although subdural fluid collection is a usual complication of SIH, SIH as a risk factor for cerebral venous thrombosis (CVT) is not well-known. There are several mechanisms that could contribute to the development of CVT in SIH. Herein, we report a case of a 33-year-old woman with SIH complicated by CVT. She was treated with anticoagulation but did not receive a blood patch for the SIH, because there was resolution of orthostatic headache with bed rest and sufficient hydration. Follow-up magnetic resonance imaging showed resolution of the findings of SIH and CVT. Patients with SIH should be closely observed for any change in the headache pattern, which might suggest the development of CVT.

Project description:Background and purposeCerebral vein thrombosis (CVT) is a type of venous thromboembolism. Whether the risk of pulmonary embolism (PE) after CVT is similar to the risk after deep venous thrombosis (DVT) is unknown.MethodsWe performed a retrospective cohort study using administrative data from all emergency department visits and hospitalizations in California, New York, and Florida from 2005 to 2013. We identified patients with CVT or DVT and the outcome of PE using previously validated International Classification of Diseases, Ninth Revision, Clinical Modification codes. Kaplan-Meier survival statistics and Cox proportional hazards models were used to compare the risk of PE after CVT versus PE after DVT.ResultsWe identified 4754 patients with CVT and 241 276 with DVT. During a mean follow-up of 3.4 (±2.4) years, 138 patients with CVT and 23 063 with DVT developed PE. CVT patients were younger, more often female, and had fewer risk factors for thromboembolism than patients with DVT. During the index hospitalization, the rate of PE was 1.4% (95% confidence interval [CI], 1.1%-1.8%) in patients with CVT and 6.6% (95% CI, 6.5%-6.7%) in patients with DVT. By 5 years, the cumulative rate of PE after CVT was 3.4% (95% CI, 2.9%-4.0%) compared with 10.9% (95% CI, 10.8%-11.0%; P<0.001) after DVT. CVT was associated with a lower adjusted hazard of PE than DVT (hazard ratio, 0.26; 95% CI, 0.22-0.31).ConclusionThe risk of PE after CVT was significantly lower than the risk after DVT. Among patients with CVT, the greatest risk for PE was during the index hospitalization.

Project description:Background and purposeCerebral venous thrombosis (CVT) is a rare but life-threatening disease. Timely and proper treatments are the keys in saving patients' life and preventing from permanent neurological deficits. We performed this network meta-analysis to evaluate the role of anticoagulation in CVT, especially for the patients accompanied with hemorrhagic stroke.MethodsPubMed, Embase, Web of Science, Cochrane Database, and Chinese Biomedical (CBM) databases were searched comprehensively to select eligible articles (up to 30 June 2017). Network meta-analysis was performed based on classical frequency statistics.ResultsAround 14 studies comprising 1135 cases were included. Overall analysis showed that low-molecular weight heparin (LMWH) and unfractionated heparin (UFH) were more effective (LMWH vs placebo: OR 4.76, 95%CI: 2.56-8.33; UFH vs placebo: OR 4.12, 95%CI: 2.17-8.33), and safe (LMWH vs placebo: OR 0.22, 95%CI: 0.069-0.65; UFH vs placebo: OR 0.28, 95%CI: 0.058-0.99) than placebo in the management of CVT. Besides, LMWH showed more advantages than UFH; As for the patients accompanied with hemorrhagic stroke, LMWH and UFH were also better than placebo (efficacy: LMWH vs placebo: OR 20, 95%CI: 5.56-100; UFH vs placebo: OR 12.5, 95%CI: 3.7-33.3; safety: LMWH vs placebo: OR 0.18, 95%CI: 0.04-0.77; UFH vs placebo: OR 0.16, 95%CI: 0.04-0.6) in the management of CVT. In addition, LMWH was more effective than UFH for the patients accompanied with hemorrhagic stroke.ConclusionAnticoagulant treatment with heparin is safe and beneficial for patients with CVT, even for those accompanied with hemorrhagic stroke. Besides, LMWH is better than UFH in the management of CVT.

Project description:ObjectiveWe aimed to estimate the incidence of cerebral sinus and venous thrombosis (CVT) within 1 month from first dose administration and the frequency of vaccine-induced immune thrombotic thrombocytopenia (VITT) as the underlying mechanism after vaccination with BNT162b2, ChAdOx1, and mRNA-1273, in Germany.MethodsA web-based questionnaire was e-mailed to all departments of neurology. We requested a report of cases of CVT occurring within 1 month of a COVID-19 vaccination. Other cerebral events could also be reported. Incidence rates of CVT were calculated by using official statistics of 9 German states.ResultsA total of 45 CVT cases were reported. In addition, 9 primary ischemic strokes, 4 primary intracerebral hemorrhages, and 4 other neurological events were recorded. Of the CVT patients, 35 (77.8%) were female, and 36 (80.0%) were younger than 60 years. Fifty-three events were observed after vaccination with ChAdOx1 (85.5%), 9 after BNT162b2 (14.5%) vaccination, and none after mRNA-1273 vaccination. After 7,126,434 first vaccine doses, the incidence rate of CVT within 1 month from first dose administration was 0.55 (95% confidence interval [CI] = 0.38-0.78) per 100,000 person-months (which corresponds to a risk of CVT within the first 31 days of 0.55 per 100,000 individuals) for all vaccines and 1.52 (95% CI = 1.00-2.21) for ChAdOx1 (after 2,320,535 ChAdOx1 first doses). The adjusted incidence rate ratio was 9.68 (95% CI = 3.46-34.98) for ChAdOx1 compared to mRNA-based vaccines and 3.14 (95% CI = 1.22-10.65) for females compared to non-females. In 26 of 45 patients with CVT (57.8%), VITT was graded highly probable.InterpretationGiven an incidence of 0.02 to 0.15 per 100,000 person-months for CVT in the general population, these findings point toward a higher risk for CVT after ChAdOx1 vaccination, especially for women.

Project description:Endovascular therapy of cerebral venous thrombosis using modern approaches to intracranial recanalization, such as stent retrievers and aspiration thrombectomy, is not well described. We performed a retrospective review of data for consecutive patients with venous sinus thrombosis who underwent endovascular treatment between 1 January 2010 and 31 December 2013 at participating institutions. We identified a total of 13 patients with a diagnosis of cerebral venous thrombosis. The most frequently utilized type of endovascular intervention was the Penumbra aspiration system (Penumbra Inc., Alameda, California, USA) (nine cases), followed by local infusion of tissue plasminogen activator (bolus and/or drip in six cases) and stent retrievers (Solitaire FR (Covidien, Irvine, California, USA) in three cases and Trevo (Stryker, Kalamazoo, Michigan, USA) in one case). Overall, multimodality treatment (two or more different types of devices or approaches) was performed in 62% of cases. Follow-up data were available for 11 patients; of those, five had a favorable clinical outcome (defined as modified Rankin Scale score of 0-2) and three patients died. Various endovascular approaches are utilized in current clinical practice. A multimodal approach to endovascular therapy for the treatment of cerebral venous thrombosis resulted in partial or complete restoration of flow in all cases, yet the mortality rate of 27% indicates the need for improvement in recanalization strategies for this disorder.

Project description:PurposeWe report a case of neurosarcoidosis that presented simultaneously with oculomotor nerve palsy, contralateral abducens nerve palsy, and paresthesia of both lower limbs.ObservationsA 69-year-old Japanese woman who suffered from repeated diplopia and lower-limb paresthesia was referred to our hospital. Ophthalmic findings included oculomotor nerve and contralateral abducens nerve palsies. No remarkable abnormalities were detected via enhanced brain magnetic resonance imaging (MRI), chest X-ray, and cerebrospinal fluid analysis. Chest computed tomography (CT) was performed to exclude neoplastic lesions; this revealed right hilar lymphadenopathy, and positron emission tomography MRI showed strong 18-F fluorodeoxyglucose uptake in the hilar lymph node. Biopsy of the lymph node showed non-caseating epithelioid granulomatous tissue, leading to a diagnosis of probable neurosarcoidosis. After the initiation of oral prednisolone treatment, the patient experienced complete remission without any recurrence.Conclusions and importanceWhen examining a patient presenting with multiple cranial neuropathies of unknown cause, neurosarcoidosis should be considered as a differential diagnosis and chest CT should be performed even when the chest X-ray and angiotensin-converting enzyme appears normal.

Project description:The prognosis of cerebral venous sinus thrombosis (CVST) is variable, and outcome may range from complete recovery to death. Prognostic factors to predict outcome in the acute phase of CVST have not been analysed in a prospective study. Prognostic factors in patients enrolled in a clinical treatment trial were prospectively investigated. Poor outcome after 12 weeks, defined as death or dependency (Oxford handicap score > or =3), was used as the principle outcome measure. Univariate relations between possible prognostic factors and outcome at 12 weeks were analyzed with chi(2) tests. Treatment and all factors associated with prognosis (p< or = 0.25) were forced into a logistic regression model with a forward selection procedure. Fifty nine patients (50 women, nine men) were studied, with a mean age of 37 years (range 18 to 80 years). After 12 weeks 10 patients (17%) had a poor outcome. The univariate identified factors related to poor outcome were papilloedema, altered consciousness, coma, age older than 33 years, diagnostic delay < or =10 days, intracerebral haemorrhage, and involvement of the straight sinus. Isolated intracranial hypertension and a delta sign on CT were associated with good outcome. In the multivariate analysis coma and cerebral haemorrhage were significantly associated with a poor outcome, with odds ratios of 8.2 (95% confidence interval (95% CI) 1. 3-50.1) and 20.7 (95% CI 1.6-264.3) respectively. Involvement of the straight sinus was also weakly, but not significantly, associated with poor outcome. In conclusion, coma and intracerebral haemorrhage are independent predictors for poor outcome of CVST.

Project description:BackgroundNeutrophil extracellular traps (NETs) contribute to the creation of a coagulation state in various diseases. Currently, it is not clear whether NETs are present in the thrombi and plasma of patients with cerebral venous sinus thrombosis (CVST). This study aimed to investigate the presence of NETs in thrombi and blood samples from CVST patients and the procoagulant activity (PCA) of NETs during the progression of CVST.ResultsThrombi obtained from CVST patients undergoing thrombectomy were examined by immunochemistry using neutrophil elastase (NE), CD66b and citrullinated histone H3(citH3). The presence of NET markers in samples from 37 CVST patients and 32 healthy people was evaluated by ELISA. NET-producing neutrophils and neutrophil-platelet (PLT) aggregates were examined in samples obtained from CVST patients and healthy people by flow cytometry. The TAT complex in plasma sample from each group was detected by ELISA to evaluate the procoagulant activity of NETs in CVST patients. Neutrophils from healthy subjects were treated with PLT-rich plasma in the presence of anti-PF4 antibodies or an autophagy inhibitor and analyzed by flow cytometry and confocal microscopy. After treatment with NETs, the expression of von Willebrand factor (VWF), tissue factor (TF) and CD31 in human brain microvascular endothelial cells (HBMECs) was measured by confocal microscopy and western blotting. Our results showed that NETs were abundant in the plasma and thrombi from CVST patients. Platelet factor 4 (PF4) from CVST PLTs induced NET generation through autophagy. NETs could induce PCA by modulating TF and phosphatidylserine (PS) in CVST. NETs also disrupted the endothelial barrier and transformed ECs into a procoagulant phenotype to exacerbate thrombogenicity.ConclusionsNET generation was mediated by PF4 from PLTs through autophagy and contribute to thrombosis in CVST patients.
