Active clinical trials for "Thrombosis"

By using the ultrasound power delivered by fragmatome, the hard, organized blood clot could be removed easily.

Examination of the prevalence of thrombosis in COVID-patients, especially in an out-patient setting. Assessment by duplex sonography. If thrombosis is detected, we will correlate it with immunity status. Assessment of health issues and cognitive function as late complication after infection.

This study aims to investigate the incidence of venous thromboembolism in people who are diagnosed with atopic dermatitis.

Little is known about the current management status of venous thromboembolism (VTE) in Southwestern China. We aimed to investigate the status of anticoagulant administration in VTE in Southwestern China and assess the potential predictors of deep vein thrombosis (DVT) complicated pulmonary embolism (PE). We extracted data from YiduCloud database from December 2006 to November 2018 and performed a cross-sectional survey of VTE. The demographics, laboratory tests, and anticoagulants were collected and analyzed in the logistic regression model, classification tree and Random Forest model.

The primary objective of this study is to evaluate the practice patterns of rivaroxaban usage invenous-thromboembolism (VTE) and non-valvular atrial fibrillation (NVAF) in cancer patients. The secondary objectives are to evaluate outcomes such as recurrent VTE, stroke and bleeding for cancer patients on rivaroxaban.

The purpose of the study is to evaluate the performances of Soluble Fibrin assay for exclusion of Pulmonary Embolism and Deep Venous Thrombosis. Secondary objectives are to determine the threshold value from the ROC curves, the possible interest in the positive diagnosis of Venous Thromboembolism (VTE), and to verify the absence of influence of age on the SF results.

The etiologies of varicose veins and the progression to more serious forms of chronic venous disease and identification of appropriate diagnostic tests to better aid patient management by identifying individuals who may benefit from more aggressive treatment and/ or prophylactic measures.

This is a prospective study consisting in testing whether systematic use of aspirin is beneficial for primary prevention of vascular access for hemodialysis attested by doppler ultrasound exam. The investigators will study aspirin resistance in the population of patients undergoing hemodialysis. The investigators will test sensibility of resistant patients to aspirin dose escalation. PFA-100 is the biologic test used in this study to define aspirin resistance.

Lybrel® is an oral contraceptive that delivers low doses of levonorgestrel and ethinyl estradiol (90 μg/20 μg). Lybrel is taken on a continuous basis without a placebo or pill-free interval to inhibit menstrual cycle bleeding by delivering a steady level of the 2 hormones for as long as the drug is used. Lybrel was marketed in the US in July of 2007. The objective of this database case-control study is to estimate the risk of idiopathic VTE (deep vein thrombosis and pulmonary embolism) in current users of Lybrel (ethinyl estradiol 20ug/levonorgestrel 90ug) compared to current users of other oral contraceptives containing 20μg of ethinyl estradiol.

The investigators aim to determine the complications and risk factors related with peripherally inserted central catheters (PICCs) and central venous catheters (CVCs) in cancer patients.
