Active clinical trials for "Thromboembolism"

In France, venous thromboembolic (VTE) disease is usually managed by vascular medicine physicians (VMP). The national OPTIMEV study, conducted more than 12 years ago among VMP practicing in hospital and in the community described the management of VTE in routine clinical practice. Since then a large number of practice changing studies have been published. This includes trials that have validated the use of direct oral anticoagulants (DOAC), the new standard of care of VTE, as per new national and international guidelines. Management of VTE in 2019 appears to be significantly different from the one that prevailed more than 10 years ago when the last national survey was conducted. It is therefore important to have an update on the routine clinical practice management of VTE by VMP. In this perspective the investigators aim to conduct a national survey among VMP practicing in France

The aims of the study are to to associate anticoagulation (AC) regime with outcome in critically ill patients with Covid-19. This will be done by describe baseline characteristics and comorbidities before hospital admission, level of organ support and dose of AC treatment and associate this with 28 days survival, survival outside ICU, thromboembolic event and bleeding complications.

Pelvic fracture are very often treated by surgery ; however there are a high level of thrombotic risk during the surgery (venous thrombo embolic events represent about 10% to 50%. The aim of our study is to report the number of these events and identify the risk factor associated to these events regarding Greenfield Risk Assessment Profile .

The purpose of this study is to determine how frequently children undergoing elective neurosurgical procedures develop blood clots in the deep veins of the legs while hospitalized. The information gained from this study will help us determine when children children need to receive therapy to help prevent this type of blood clot from forming.

The main objective of this study is to evaluate, for 15 healthy volunteers and for 15 patients with a history of venous thromboembolism (VTE), the monthly variation (over 6 months) of plasma nucleosome and free DNA concentrations.

Venous thromboembolism(VTE) is the third most common cardiovascular complication among hospitalized patients, and can even cause death. VTE often occurs in intensive care patients and there had been many efforts to prevent such complication. The American College of Chest Physicians (ACCP) had published evidence-based clinical practice guideline for VTE prophylaxis. This study focuses on how VTE prophylaxis is being performed in both medical and surgical ICUs in a single University hospital, and sees the differences in such prophylactic patterns.

The objective of this observational study is to characterize long-term (5 years post event) clinical outcomes in patients who experienced a thromboembolic event (TEE) during participation in the GSK ENABLE clinical trials. Patients eligible for the study are patient who experienced a TEE during participation in the ENABLE trials. Each included patient will be followed for a period of 5 years from the date of their first TEE. Demographic and clinical characteristics will be collected for the index date (time of TEE) and every sixth month during the follow-up period, information will be collected for the outcomes of interests: mortality, new TEE, hepatic decompensation, evaluation for liver transplant and result of evaluation, and liver transplantation. All information will collected by medical record review.

Can thrombin generation measurement predict the risk of venous thromboembolism in acute ill patients Traditional coagulation tests do not assess the whole coagulation system. Thrombin generation assays measure the ability of plasma sample to generate thrombin following in vitro activation of coagulation. In contrast to the classical clotting assays, thrombin generation reflects and integrates all pro and anticoagulant reactions that regulate the formation and inhibition of thrombin. The aim of our study is to investigate whether thrombin generation would be able to predict a hypercoagulable state in acute ill patients admitted in the internal medical departments and how it correlates with the Padua prediction score, a score that could assists the risk for venous thromboembolism in hospitalized medical patients. In total 300 patients are planned for inclusion in this trial. After signing an informed consent a blood sample will be obtained from each participant. We will measure the thrombin generation over time in plasma assessed by the calibrated automated thrombogram (CAT).

The study purpose is to document the prescription and the use of Low Molecular Weight Heparin in usual medical practice in patients with cancer and established Venous Thromboembolism. This study also aims at gathering epidemiological data on the Low Molecular Weight Heparin therapy of Venous Thromboembolism in patients with cancer.

Because of a high recurrence risk after unprovoked venous thromboembolism (VTE) indefinite anticoagulation is recommended, but confers a considerable bleeding risk. It is important to identify patients, in whom the recurrence risk is lower than the expected bleeding risk, and who will not benefit from long term anticoagulation. By use of a scoring model (Vienna Prediction Model), patients can be stratified according to their recurrence risk based on their sex, location of VTE and D-Dimer. Before implementation in routine care, an independent validation is required. Patients with unprovoked VTE will stop anticoagulation after 3-7 months and the recurrence risk will be estimated by use of the Vienna Prediction Model. Low risk patients with a score of <180 will be included and will be left untreated. Patients with a high score will not be included and their management will follow current guidelines. Follow-up will be two years and the endpoint will be recurrent symptomatic VTE.
