Active clinical trials for "Venous Thromboembolism"

The purpose of this study is to demonstrate the ability of STA® Liatest® D-Di combined with a clinical pretest probability (PTP) to safely exclude pulmonary embolism (PE) or Deep Venous Thrombosis (DVT) in a 3 month follow-up.

The purpose of this prospective multicenter cohort study is to examine long-term medical outcomes, quality of life, and medical resource utilization in elderly patients (>= 65 years) with acute venous thromboembolism (i.e., acute pulmonary embolism and/or deep vein thrombosis)

The purpose of this study is to describe the incidence of thromboembolic events in relation to pregnancy and when in pregnancy and the puerperal period.

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. .

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.

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.

The aim of this study is to evaluate the frequencey and the determinants of postpartum major complications (hemorrhage and thrombosis) up to 3 months after delivery in the maternity hospitals of Finistère (Bretagne - France)

Occurrence of venous thromboembolism during in Vitro Fertilization (IVF) pregnancies has been reported in numerous case reports and in two small consecutive series. The incidence of venous thromboembolism (VTE) after IVF has been claimed to be comparable to the incidence of VTE during normal pregnancy. No information exists concerning pulmonary embolism (PE). The aim is to estimate and compare the risk of both PE and VTE during the the different phases of pregnancy after IVF to that in age and period matched control women. The investigators will use the Swedish National Health Registers to estimate the risk.

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.

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.
