Filter by:Researchers are looking for a better way to treat people who have deep vein thrombosis (DVT). DVT is a condition that occurs when a blood clot forms in a deep vein in the leg. DVT is called 'proximal' when the clot is formed in the veins of the hip, thigh, and knee. DVT can cause serious health problems. The blood clots in the veins can break loose and can then travel through the bloodstream and get stuck in the lungs, blocking blood flow to the lungs. Symptoms of DVT include swelling, pain, and tenderness in the affected leg, as well as redness and warmth in the area. Currently, DVT is usually treated using blood thinners to prevent the clot from getting bigger or breaking off and traveling to the lungs. However, blood thinners may not be able to remove a blood clot quickly and may not be suitable for everyone who has DVT. BAY3018250 is a drug that works by dissolving blood clots. In this study, researchers will compare BAY3018250 with placebo to learn how well it works and how safe it is in participants with proximal DVT. A placebo looks like the study drug but does not have any medicine in it. Using a placebo helps researchers to confirm that the results observed during the study were caused by the study drug and not by other factors. The main purposes of this study are to learn: - How well BAY3018250 works in dissolving blood clots in participants with proximal DVT and - How safe is BAY3018250 as a treatment for participants with proximal DVT? For this, the researchers will use ultrasound tests to measure blood clots in participants before and at various times after study treatment. They call these measurements a clot burden score. They will compare the clot burden score before and after treatment and will calculate a complex measure called AUC. This tells researchers how the clots have changed over time. And researchers will collect the number of bleeding events that require medical attention. The study participants will be randomly (by chance) assigned to one of 3 treatment groups. Dependent on the group, they will receive a single dose of high dose or low dose of BAY3018250 or placebo. Researchers will closely monitor participants for 90 days after receiving the study treatment. During the study, the doctors and their study team will: - take blood samples - do physical examinations - examine heart health using electrocardiogram (ECG) - check vital signs such as blood pressure, heart rate - undergo ultrasound tests to measure the blood clots - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatments.
The study aims to compare the modified approach through ipsilateral deep calf venous access of contralateral femoral venous access with the traditional approach through ipsilateral popliteal venous access for mixed type deep venous thrombosis (DVT), and determine whether it can achieve similar therapeutic effects as central type DVT.
Portal vein thrombosis (PVT) can lead to a further increase in portal venous pressure and increase the risk of rebleeding. Whether patients with acute esophagogastric variceal bleeding with occlusive PVT benefit from preemptive TIPS is still controversial. The present study is directed at comparing the outcome of patients with acute variceal bleeding with occlusive PVT treated by standard therapy (vasoactive drugs + endoscopic variceal ligation) with or without preemptive TIPS (performed during the first 1-3 days after endoscopic procedure). The primary outcome is survival free of variceal rebleeding at 6 weeks from inclusion.
The aim of study is to evaluate different etiological and risk factors that lead to chronic portal vein thrombosis and to delineate a management plan for chronic portal vein thrombosis in children.
To study thrombin generation parameters in critically ill patients with and without central line related thrombosis (CRT).
The goal of this clinical trial is to evaluate tailored duration of long-term anticoagulant treatment after a first venous thromboembolism based on individualized risk assessments of recurrent VTE and major bleeding risks. Participants will be asked to fill in a questionnaire and take a buccal swab, which are used for an individual estimation of the risks of recurrent VTE and bleeding. Based on these risks a treatment advise will be made, or randomised in a subgroup of patients.
This study will conduct a prospective single blind controlled study on the clinical efficacy and safety indicators of 50 cancer patients with acute lower limb deep vein thrombosis (DVT). The patients were randomly divided into an experimental group (improved mechanical thrombectomy (PMT) group) and a control group (traditional simple anticoagulation group) using the "envelope method", with 25 cases each. After the end of treatment, clinical prognosis evaluations were conducted on the patient's vital signs, symptoms and signs, lower limb Doppler ultrasound examination, patient PTS score (Villalta score), quality of life score (QOL), etc. at 3, 6, and 12 months. Adverse events, the presence or absence of thrombus recurrence, and re surgical intervention were recorded. This study is expected to propose a new strategy for the treatment of acute DVT in cancer patients, thereby improving the overall level of VTE prevention and treatment.
Venous thromboembolism is prevalent, associated with a high degree of morbidity and mortality, and largely preventable. External mechanical compression is a standard of care for prevention, but compliance with traditional external mechanical compression devices is low due to patient reported issues with comfort, mobility, usability, noise, and sleep disturbances. The purpose of this study was to compare user-rated comfort, mobility, usability, noise, perceived sleep disturbance, and objective sleep disturbance for a novel external lower limb mechanical compression device as compared to a standard sequential compression device. Using a 2-day counterbalanced, within-subject repeated-measures design, 16 participants wore two mechanical compression devices, the commonly-used Kendall sequential compression device Express 9525 and the novel Recovery Force Movement and Compressions Device for 1 night each in their home while sleep was recorded with polysomnography. For each device, participants also completed questionnaires to assess usability, mobility, perceived noise disturbance, and perceived sleep disturbance.
Compression ultrasonography (CUS), which is the gold-standard for the diagnosis of deep vein thrombosis, cannot provide adequate information on the timing of the onset of thrombosis. Shear-Wave elastography, a technique used to assess tissue elasticity and widely used in hepatology, could play a crucial role in distinguishing between acute and chronic deep vein thrombosis. This study aims at evaluating the efficacy and diagnostic and prognostic accuracy of Shear-Wave elastography in distinguishing between acute and chronic deep vein thrombosis.
Based on data on a cohort of 2,141 patients undergoing elective colonic cancer resection in an ERAS program, the incidence of postoperative thromboembolic events is estimated in patients no receiving prolonged thromboembolic prophylaxis.
