Active clinical trials for "Thrombosis"

The aim of this study is to compare the accuracy and clinical predictive value of the Michigan Risk Score, Caprini Risk Assessment Model , and Maneval Scale （Chinese version）in predicting PICC-related thrombosis.

The purpose of this study is to create a state-wide biorepository and resource center for cerebrovascular diseases in Florida, which will include collecting medical history information and blood from families affected by cerebrovascular disease. The information and blood samples collected may be used in future research for the study of cerebrovascular disease and to learn about, prevent or treat other health problems.

The anatomical characteristics of veins and venous sinus result in great differences between cerebral venous system diseases and cerebral artery diseases in etiology, pathophysiology and clinical features.Therefore, understanding the anatomy and variation of normal venous sinuses is essential to identify the intracranial venous lesions.

Background: Deep venous thrombosis (DVT) is a common and important vascular disease due to its morbidity and mortality. Its incidence remains high throughout the world and constitutes serious problems for national and international public health. Several inherited and/or acquired risk factors may be responsible for thrombus formation. Few epidemiological data regarding real world panorama of this disease in South America and Brazil is available in the literature. Objective: Evaluate demographic data, diagnostic methods and treatment of deep vein thrombosis in the real world in public university hospitals in Brazil. Methods: Five-year prospective records of deep venous thrombosis have been collected by the RHEUNI group of five public schools in the State of São Paulo. Demographic data of patients will be evaluated along with the main risk factors, clinical picture, diagnostic methods, use of different drugs to treat the disease and its complications. Digital platform has been used in data collection. Is a multicenter study and analysis will be performed using Microsoft Excel and Epi-Info. Key words: deep vein thrombosis, assessment, risk factors, demographic data.

The purpose of this prospective cohort study is to investigate whether antithrombotic therapy in the secondary prevention of ischemic stroke increases the risk of the emerging CMBs and whether the change is associated with an increased risk of intracranial hemorrhage, providing an imaging evidence for individualized antithrombotic therapy in such patients.

Ongoing registration of patients with venous thromboembolism treated by means of antithrombotic therapy, thrombolisys, open surgery, endovenous desobstruction and stenting.

The purpose of this study is to identify risk factors of cancer-associated venous thrombosis and develop a prediction model to assist clinicians in tailoring anticoagulant therapy.

This is a pragmatic, multi-center, prospective, observational, non-interventional study and standing database of patients hospitalized for transient ischemic attack (TIA) or stroke in the 11 accredited adult neurology training institutions in the Philippines. Data will be collected from each patient while admitted in the hospital and until hospital discharge. Data collection for this study will span 3 years from study initiation, after which the utility of an extension or a re-implementation of the study will be assessed.

This research is based on clinic treatment of intravenous thrombolysis for patients with acute ischemic stroke.By building up a database of these patients, the investigators aim to find some significance between groups by analyzing population information, clinical status and such for better evaluation and optimal treatment decision.

This is a single-center prospective cohort study of predictive factors related to prognosis of ischemic stroke due to large-artery atherosclerosis. From March 1, 2021 to December 31, 2026, 1000 patients with ischemic stroke due to large-artery atherosclerosis who are admitted to the Department of Neurology or Neurosurgery, Tongji Hospital are going to be recruited. Detailed clinical data in emergency room and in-hospital will be obtained from the medical record reviews, and the National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin Scale (mRS) score will be done by certified neurologists to assess the severity of the disease in acute stage and treatment outcome during the follow-up. All cases will undergo routine blood tests, brain magnetic resonance imaging (MRI) and cerebral vascular examination, such as TCD, CTA, HRMR or DSA. The investigators will analyze the in-hospital factors that could predict the outcome to provide more evidence-based suggestions in the treatment and prognosis of atherosclerotic ischemic cerebrovascular disease.
