Florida Cerebrovascular Disease Biorepository and Genomics Center

Cerebrovascular DiseaseIschemic Stroke17 more

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.

Real World Study of Deep Venous Thrombosis. Analysis of Prospective Cases in University Hospitals...

Registry

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.

Deep Venous Thrombus Characteristics and Venous Dynamics With Subsequent Thrombus Resolution and...

Deep Vein Thrombosis

The goal of this study is to examine in vivo thrombosis characteristics with ultrasound shear wave elastography (SWE) and determine the relationship with thrombus resolution and postthrombotic syndrome (PTS) in patients with acute proximal Deep Vein Thrombosis (DVT).

Philippine Neurological Association One Database - Stroke

Transient Ischemic AttackIschemic Stroke3 more

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.

Apixaban in Preventing Secondary Cancer Related Venous Thrombosis in Cancer Patients Who Have Completed...

Cerebral Vein ThrombosisDeep Vein Thrombosis5 more

This randomized phase III trial studies the best dose of apixaban and how well it works in preventing secondary cancer related venous thrombosis in cancer patients who have completed anticoagulation therapy. Apixaban may help in prevention by blocking some of the enzymes needed for venous thrombosis.

Risk of Recurrent Venous Thromboembolism After Provoked Venous Thromboembolism

Recurrent Venous Thrombosis

Venous thromboembolism (VTE) is a common disease with an incidence of 1-2/1000 persons per year. VTE is a chronic disease with a considerable risk of recurrence. Patients with unprovoked VTE, i.e. VTE in the absence of a temporary risk factor including surgery, cancer or immobilisation, have a high recurrence risk and indefinite anticoagulation is generally recommended. The recurrence risk of patients with VTE provoked by a transient risk factor is regarded as low. Discontinuation of anticoagulation after three months is recommended because the benefit of reducing the recurrence risk further by prolonged anticoagulation is outweighed by the bleeding risk. However, the newer direct oral anticoagulants are potentially associated with a lower bleeding risk than vitamin K antagonists. Because they are also meanwhile widely available and are convenient there is a trend towards prolonging anticoagulation also in patients with a VTE after a transient provoking factor. However, the definition of transient provoking factors is imprecise and a distinct categorization according to the risk of recurrence is lacking. Preliminary evidence suggests that the recurrence risk varies considerably between the different transient provoking factors. In a prospective cohort study, the investigators will include patients with a deep vein thrombosis or pulmonary embolism provoked by a transient risk factor defined according to Guidance of the Scientific and Standardization Committee of the International Society on Thrombosis and Haemostasis (Kearon et al., J Thromb Haemost 2016; 14: 1480-3) after discontinuation of anticoagulation. The study endpoint is recurrent symptomatic VTE.

The Norwegian Cerebral Venous Thrombosis Study

Cerebral Vein ThrombosisCerebral Venous Sinus Thrombosis

The NoCVT study will investigate CVT (2010-2019) in a large Norwegian population (> 3 millions) using several approaches combining existing health registries, clinical databases and new prospectively collected clinical data to explore epidemiology, risk factors, diagnostics, treatment, and the long-term prognosis of CVT.

EXERT: Exercise Physiology After Thrombosis

Venous Thrombosis Deep (Limbs)Post Thrombotic Syndrome

Deep vein thrombosis (DVT) can cause long-term scarring and narrowing of veins. When there is extensive damage to the veins in the legs, groin or abdomen it can affect the way that blood is able to flow back up to the heart. Some patients are left with severe symptoms such as pain, leg swelling and ulcers, and have surgical treatment with nitinol stents to re-open the veins and relieve symptoms. The primary aim of this study is to investigate venous blood flow to the heart during exercise in patients with extensive damage to the veins in the groin and abdomen after DVT, and changes that happen after stenting.
