DEEP VEIN THROMBOSIS

This study tests whether a lower dose of the blood thinner apixaban can safely treat blood clots in cancer patients who also have low platelet counts. About 30 participants will receive the adjusted dose, and researchers will track how many complete the treatment and how many hav…

This study looks at whether using two types of blood thinners (anticoagulant plus antiplatelet) after a vein stent procedure helps keep the vein open longer and prevents blood clots from returning. About 172 people with deep vein thrombosis and a narrowed iliac vein will take par…

This study aims to see if giving blood thinners based on a person's individual risk—rather than a standard dose for everyone—can lower the chance of dangerous blood clots and bleeding after hip or knee replacement. About 10,000 adults scheduled for joint replacement will be assig…

This study compares two blood thinners—rivaroxaban (a pill) and low-molecular-weight heparin (a daily injection)—in people with leg injuries that require a cast or brace for at least two weeks. The goal is to see if the pill is as good as or better than the injection at preventin…

This study compares three methods of removing blood clots from deep leg veins in people with acute deep vein thrombosis (DVT). The goal is to see if newer approaches work as well as the standard method and reduce the risk of long-term complications like post-thrombotic syndrome. …

This study follows 82 people who receive a vena cava filter to prevent blood clots from reaching the lungs. The filter is placed in a large vein to catch clots. Researchers will check for complications like filter movement or breakage and how well the filter works over up to 5 ye…

This study is testing whether doing regular leg ultrasound scans on critically ill patients in intensive care can help detect dangerous blood clots (deep vein thrombosis) early. Finding clots early might prevent them from traveling to the lungs (pulmonary embolism) and potentiall…

This study looks at the best time to start blood thinners (heparin) in people who have had a brain bleed due to high blood pressure. The goal is to prevent dangerous blood clots in the legs or lungs without causing more bleeding in the brain. About 200 participants will be random…

This study tests a new, non-invasive way to measure blood flow in the legs using an air-filled bladder placed under a compression cuff. Researchers want to see if this method can help detect deep vein thrombosis (DVT) more easily. About 500 adults who recently had a leg ultrasoun…
