Filter by:The goal of this observational study is to assess the utilization of mechanical thrombectomy and catheter-directed thrombolysis in patients with deep vein thrombosis in tertiary care. The main questions it aims to answer are: 1. How many patients with deep vein thrombosis are potentially eligible for mechanical thrombectomy and catheter-directed thrombolysis in a tertiary hospital? 2. What is the actual number of patients undergoing endovascular interventions for deep vein thrombosis? Participants received endovascular treatment according to the clinical protocol of the treatment.
T-REX HMB is a pilot randomized controlled trial (RCT) designed to assess the feasibility of a full trial comparing tranexamic acid (TXA) to placebo in decreasing HMB in premenopausal individuals anticoagulated for VTE. Strong data supports TXA as an effective and safe agent at decreasing HMB in the general population, but its use in those with VTE has been limited by a lack of data for its efficacy in anticoagulated individuals and theoretical concerns of its prothrombotic effects.
The aim is to improve the diagnosis of chronic lower limb venous thrombosis before a lower limb venous recanalization procedure. Additionally, if the MRI scores are comparable to those of the CT, MRI would reduce radiation exposure and limit the need for foot vein punctures that accompany CT use.
While blood clots after major cancer surgery are common and harmful to patients, the medications to decrease blood clot risk are seldom used after patients leave the hospital despite the recommendation of multiple professional medical societies. The reason why these medications are seldom prescribed is not well understood. The main questions this study aims to answer are: - Does surgeon education paired with an electronic medical record based decision support tool improve the guideline concordant prescription of pharmacologic venous thromboembolism after abdominopelvic cancer surgery? - Does dedicated patient education regarding blood clots at the time of hospital discharge after abdominopelvic cancer surgery improve understanding of the risk of venous thromboembolism and adherence to pharmacologic prophylaxis? The investigators will study these questions using a stepped-wedge randomized trial where groups of surgeons will use a tool integrated to the electronic medical record to educate them on the individualized patient risks of blood clots after major cancer surgery and inform them regarding guidelines for preventative medicines. Utilization of the medications before and after using the tool will be compared. Patients will be administered a questionnaire assessing their awareness of blood clots as a risk after cancer surgery. For those prescribed medications to reduce blood clot risk after leaving the hospital, the questionnaire will evaluate whether they took the medications as prescribed. Survey results will be evaluated before and after implementation of education on blood clot risk at the time of hospital discharge.
Purpose of the pilot trial: To assess the feasibility of a full-scale, double-blind, placebo-controlled, randomized trial assessing whether low-dose colchicine (0.5 mg daily) reduces the risk of post-thrombotic syndrome (PTS) in patients with proximal lower extremity deep vein thrombosis (DVT).
Patients with colorectal cancer (CRC) have a higher risk of both venous thromboembolism (VTE) and major bleeding (MB). Patients with CRC are underrepresented in the major trials examining treatment of cancer-associated VTE with anticoagulant.
The aim of the study isto evaluate the inter-observer reliability of the assessment of venous thromboembolic risk using the TRiP(cast) score in patients presenting with trauma to a lower limb requiring immobilisation, and of the clinicians' assessment using the physician's implicit probability (gestalt) compared with the use of the TRiP(cast) score.
Intimate violence against individuals, which is particularly marked among women, is one of the most widespread human rights violations in the world. The Women Abuse Screening Tool (WAST) self-questionnaire is a screening tool validated in French. Our preliminary data describing the association between intimate violence against women and the first attack of unexplained venous thromboembolic disease, show a significant frequency of positive responses to the WAST among women attending a biological hematology consultation at the CHU de Nîmes, for reasons of hemostasis disorders (8% out of the first 200 cases). The study authors wish to establish the prevalence of this situation among patients presenting to the CHU de Nîmes for hematological exploration and management. They hypothesize that the prevalence of violence against individuals seen in Hematology consultations is higher among individuals with hemostasis pathologies (hemorrhagic and thrombotic pathologies) than those with cellular pathologies, and higher among women than men.
Venous thromboembolic disease (VTE) is a common (1/1000), potentially serious disease (10% mortality when the clinical presentation is that of pulmonary embolism (PE)). In cancer patients, the risk of developing VTE is high and constitutes a negative prognostic factor for cancer; the risk of bleeding is also increased. The study of VTE in the context of cancer is a major challenge, given the frequency of the association, the heterogeneity of the situations, the risk factors involved and the therapeutic issues in both curative and primary prevention; in this field, many uncertainties remain, justifying a study focused on the association of VTE and cancer.
The Rhea-study is a multicenter prospective diagnostic proof-of-concept study There is an unquestionable need for improved diagnostic approaches for (incidental) SVT. The researchers plan to evaluate the MRDTI technique, that has been shown to be accurate in other settings of difficult-to-diagnosis venous thrombosis, for the notoriously challenging diagnosis of incidental SVT. This study targets an important unmet need and will provide the basis for precision medicine for patients with SVT in the near future, i.e. the possibility of assessment of the age of the thrombus in patients with incidental SVT, which is of utmost importance for determination of the indication for anticoagulant therapy. If this hypothesis is proven true, i.e. sensitivity of MRDTI for SVT is indeed >90%, the investigators will proceed with performing a randomized controlled outcome study in which patients with possible/probable chronic SVT with normal MRDTI test results and no other indications for anticoagulant therapy. These patients will be randomized between active therapeutically dosed anticoagulation versus no anticoagulation, to compare clinical outcome with regard to the occurrence of venous thromboembolism and/or Progressive symptomatic SVT as well as major bleeding.
