Epidemiology of Venous Thromboembolism

Venous ThromboembolismPulmonary Embolism3 more

More than 5 years ago the DVT FREE Registry was conceived. Its database consists of 5,451 ultrasound-confirmed DVT patients from 183 institutions. This database is rich in information of critical importance to health care providers. The information contained within the database will be revisited to provide more detailed analyses which will be used for risk factor assessment and for decision-making regarding the implementation of VTE Prophylaxis.

Prediction of the Risk of Placental Vascular Pathology and Venous Thromboembolic Disease

Placental Vascular PathologiesVenous Thromboembolism Diseases

Venous thromboembolic (VTE) disease is the first cause of maternal mortality in the world. Some other pregnancy pathologies called Placental Vascular Pathologies (PVP) are linked to VTE by biological thrombophilia and are the principal cause of perinatal mortality. the identification of predictive factors of risk of occurrence or recurrence of two pathologies could enable us to propose an appropriate monitoring of patients at risk.

Evaluation of an Antithrombotic Therapeutic Strategy in Pregnant Women

Placental Vascular PathologiesVenous Thromboembolism Diseases

The venous thromboembolism is one of the first causes of maternal mortality. Until 2003, only a few recommendations were available on the optimal use of antithrombotic therapy as a preventive measure against thromboembolism in pregnant women. In this study, we propose : To gather the experts who took part in the French consensus conference and the local experts to create a score in accordance with the national and international consensus and to give some precise therapeutic strategies. To evaluate the discriminant, feasible and useful character of this new score by a prospective multicentric study including 2000 pregnant women with a risk of thromboembolism or placental vascular pathology who will benefit from therapeutic strategies defined by the new score. .

An Observational Study on Incidence, Natural History and Treatment Patterns of Venous Thromboembolism...

Venous Thromboembolism

The research question addressed by this study is primarily on the clinical epidemiology of VTE in Taiwan. The study aims to estimate the incidence of VTE and describe natural history of VTE, including long term clinical outcomes in adult Taiwanese population, utilizing population-based electronic health data in Taiwan.

Distribution of Risk Factors for Venous Thromboembolism in Blood Donors

Venous ThromboembolismRisk Factor2 more

Venous thromboembolism occurs with an incidence of about 1 per 1000 per year in adults . The main consequences are death, recurrence, post-thrombotic syndrome and major bleeding due to anticoagulation. Mortality rates are lower among patients with idiopathic venous thrombosis and higher among those in whom thrombosis occurs in the presence of cancer. The risk increases with the age for unclear reasons. There are also differences in the incidence according to ethnicity; however, data in subjects of European ancestry are scarce. Several studies have documented an association between thrombosis and ABO group. Specifically, non-O blood groups have a higher risk of myocardial infarction, angina, peripheral vascular disease, cerebral ischemia and venous thromboembolism than O. While there are numerous studies carried out in patients who have already shown thromboembolic events, data on the incidence of risk factors in the healthy population are completely inadequate. Understanding the risk factors for venous thrombosis is necessary to maximize the prevention of this disease in individuals and groups of high-risk patients . For this purpose a self-administered questionnaire will be used. Data obtained by blood donors on exposure to risk factors will be used to set up a clinical score to validate in future studies to carry out in patients with VTE.

Incidence of Venous Thromboembolism and Professional Practices in Brest Area

Venous Thromboembolism

The aim of this study estimate VTE incidence. Investigators prospectively record all cases of symptomatic pulmonary embolism (PE) and deep vein thrombosis (DVT) of the lower limbs diagnosed between March 1, 2013 and February 28, 2014 in hospitals and in the community.
