Filter by:The aim of this study is to report the clinical presentation, Microbiological, laboratory and imaging evaluation, prothrombotic factors analysis, medical and surgical management and outcomes in children with Otogenic Cerebral Sinus Vein Thrombosis (CSVT).
There are few published data on the patterns of parenchymal imaging abnormalities in a context of cerebral venous thrombosis (CVT). The objectives of the present study were to describe the patterns of parenchymal lesions associated with CVT and to determine the lesion sites.
This is a single institutional registry database for the patients with stroke and cerebrovascular diseases. Stroke is the fifth leading cause of death in the United States. Despite extensive research, most of the patients die or suffer from varying degree of post-stroke disabilities due to neurologic deficits. This registry aims to understand the disease and examine the disease dynamics in the local community.
This is a single-center, retrospective, open-label study. This study is planned to investigate the accuracy of mRS and NIHSS, comparing with the accuracy of CSF pressure and papilledema grade in assessing cerebral venous sinus thrombosis.
This is a multi-center, prospective, international, randomized (1:1), open-label study with two parallel groups. This phase III study is planned to investigate the efficacy and safety of dabigatran etexilate versus dose-adjusted warfarin on a net clinical benefit endpoint of major bleeding (ISTH criteria) and new venous thrombotic event (VTE) (primary endpoint) with blinded endpoint adjudication.
Lybrel® is an oral contraceptive that delivers low doses of levonorgestrel and ethinyl estradiol (90 μg/20 μg). Lybrel is taken on a continuous basis without a placebo or pill-free interval to inhibit menstrual cycle bleeding by delivering a steady level of the 2 hormones for as long as the drug is used. Lybrel was marketed in the US in July of 2007. The objective of this database case-control study is to estimate the risk of idiopathic VTE (deep vein thrombosis and pulmonary embolism) in current users of Lybrel (ethinyl estradiol 20ug/levonorgestrel 90ug) compared to current users of other oral contraceptives containing 20μg of ethinyl estradiol.
Background: Endovascular thrombolysis, with or without mechanical clot removal (ET), may be beneficial for a subgroup of patients with cerebral venous sinus thrombosis (CVT), who have a poor prognosis despite treatment with heparin. Published experience with ET is promising, but only based on case series and not on controlled trials. Objective: The main objective of the TO-ACT trial is to determine if ET improves the functional outcome of patients with a severe form of CVT Study design: The TO-ACT trial will be designed as a multi-centre, prospective, randomized, open-label, blinded endpoint (PROBE) trial. Study population: Patients are eligible if they have a radiologically proven CVT, a high probability of poor outcome (defined by presence of one or more of the following risk factors: mental status disorder, coma, intracranial hemorrhagic lesion or thrombosis of the deep cerebral venous system) and the responsible physician is uncertain if ET or standard anti-coagulant treatment is better. Intervention: Patients will be randomized to receive either ET or standard therapy (therapeutic doses of heparin). ET consists of local application of alteplase or urokinase within the thrombosed sinuses, and/or mechanical thrombectomy. Glasgow coma score, NIH stroke scale and relevant laboratory parameters will be assessed at baseline. Endpoints: The primary endpoint is the modified Rankin scale (mRS) at 12 months. The most important secondary outcomes are the mRS, mortality and recanalization rate at 6 months. Major intra- and extracranial hemorrhagic complications within one week following the intervention are the principal safety outcome. Results will be analyzed according to the "intention-to-treat" principle. Assessment of study endpoints will be carried out according to standardized questionnaires by a blinded neurologist or research nurse who is not involved in the treatment of the patient. Study size: To detect a 50% relative reduction in mRS≥2 (from 40 to 20%), 164 patients (82 in each treatment arm) have to be included (two-sided alpha, 80% power). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Included patients may benefit directly from ET. Complications of ET, most notably intracranial hemorrhages, constitute the most important risk of the study.
