Active clinical trials for "Venous Thromboembolism"

Venous Thrombo-Embolic Disease (VTED) is a serious and common ailment, defined by the growth of a clot - or thrombus - in a vein, and/or as the migration of this thrombus to a pulmonary artery. It represents the third cause of death after cardio-vascular disease and cancer, and encompass superficial, muscular and Deep Venous Thrombosis (DVT), and Pulmonary Embolisms (PE), which can be isolated or associated. Ultrasound is today the most frequently used exam to diagnose DVT. However, it's unable to provide information on thrombus age or cause. Elastography is an imaging technic which aims to analyse elastic properties of a tissue, by applying a mechanical impulse on it, and could be an interesting tool in thrombus exploration, and provide additional information.

The purpose of this study is to demonstrate the ability of new D-Dimer assay 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 investigators aimed to test the reliability and validity of the Chinese version of patient-completed CRS in hospitalized patients and to evaluate whether this form can be widely used in clinical practice instead of only health care workers' evaluation.

Objectives of the study are: To estimate the incidence of venous thromboembolism (VTE) in a cohort of women with suspected ovarian cancer and evaluate changes in the coagulation system in case of benign or malignant disease. The impact of changes in the coagulation system on disease prognosis will be evaluated.

The purpose of this study is to develop a way to predict which patients diagnosed with idiopathic blood clots can safely stop warfarin therapy after six months. We will use patient characteristics, blood test results and imaging test results to identify those patients who have the lowest risk of developing a new blood clot after warfarin is stopped.
