Active clinical trials for "Venous Thrombosis"

The Registry involves the collection of information for research and educational purposes only on the use of AngioJet in the peripheral vascular system.

This registry collects observational data about how mid-length AngioJet catheters (ie XPEEDIOR and DVX models) are used in routine clinical practice.

The aim of this study is to determine the prevalence of asymptomatic lower extremity DVT detected by Doppler ultrasound in a selected group of patients suffering from gynecological malignancies.

The aim of this study is to determine the prevalence of asymptomatic lower extremity DVT detected by US-Doppler and procoagulant microparticles in a selected group of cancer patients suffering from an advanced stage of the disease. An attempt will be made to determine whether there is a correlation between this prevalence and various clinical and laboratory parameters.

There are few published data on the patterns of parenchymal imaging abnormalities in a context of cerebral venous thrombosis (CVT). The objectives of the present study were to describe the patterns of parenchymal lesions associated with CVT and to determine the lesion sites.

Venous thromboembolism (VTE - blood clots that form in deep veins or in the lungs) has been identified as a leading cause of death in economically developed countries for pregnant and recently-pregnant women. There is evidence that clotting parameters can take up to 6 weeks to return to normal for women who have had term deliveries, however there is an absence of information on time taken for clotting parameters to normalise following abortion. As such, existing guidelines are based solely on expert opinion and recommend durations of VTE prevention from as short as 7 days, up to 6 weeks following abortion. All women are assessed for risk of VTE, but data are needed to inform an evidence-based approach to prevention of VTE in these women. The findings from this pilot study have the potential to inform clinical guidance and possibly a larger study subsequently.

The purpose of this study is to investigate the prevalence of venous thromboembolism in a regional health care system (Region Östergötland, Sweden) before and during the SARS-COV-2 pandemic. In a retrospective observational study, we will review patient data, diagnostic data and treatment data over a three-month period since the onset of the SARS-COV-2 pandemic. This data will be compared with data from the corresponding time frame during the years 2015 to 2019.

This study aims to describe the incidence of catheter-related and non-catheter-related thrombosis in a population of adults in ICU and to assess its correlation with alteration of coagulation parameters.

Venous thrombosis of the upper limb is one of the manifestations of venous thromboembolic disease. The epidemiology and management of upper limb venous thrombosis is much less well documented than that of lower limb venous thrombosis. The investigators wished to provide epidemiological data concerning upper limb venous thrombosis in the hospital setting. The researchers would like to know the prevalence of this pathology among patients hospitalized in a university hospital center. In order to obtain this prevalence, the investigators wish to carry out a monocentric cross-sectional descriptive study.

The frequency of violence against women, or intimate partner violence (IPV) is more and more underlined and recognized as a cofactor favoring certain somatic and psychic pathologies. However, its incidence in patients with venous thromboembolism (VTE) is unknown and its status as a risk factor is still elusive and ambiguous. Investigators therefore conducted a matched case-control study consisting of women taking combined oral contraceptives (COC) who were investigated and followed up between 2010 and 2020. The cases are the patients investigated for their first venous thromboembolic event, The controls were women free of thrombosis who had regular gynecological checkups. Case-control pairs were matched on region of residence, age (+/- 2 years), duration of COC intake (+/- 4 months), COC type (2nd, 3rd or 4th generation).
