DEEP VEIN THROMBOSIS

This study is for cancer patients who have both a blood clot and low platelet counts. Researchers want to see if a specially adjusted dose of the blood thinner apixaban can safely treat the clot while causing fewer bleeding problems. About 30 participants will take the adjusted d…

This study tests whether giving blood thinners based on each person's risk level after hip or knee replacement works better than the standard one-size-fits-all approach. About 10,000 adults having elective hip or knee replacement will be assigned to either standard treatment or a…

This study compares three different ways to remove blood clots from deep leg veins. About 210 adults with recent deep vein thrombosis (DVT) will be assigned to one of three access points for the procedure. The goal is to see which method works best and reduces the chance of long-…

This study follows 82 people who receive a vena cava filter to catch blood clots and prevent them from reaching the lungs. Researchers will check for complications like filter movement or breakage over 5 years. The goal is to confirm the device works safely for long-term use.

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 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 looks at 200 people with high-blood-pressure-related brain bleeding to find the best time to start blood thinners (heparin) to prevent dangerous clots in the legs or lungs. Participants get heparin either within 2 days (but not before 12 hours) or starting on day 3 aft…

This study tests whether using ultrasound to check for deep-vein thrombosis (DVT) in critically ill patients can help prevent pulmonary embolism (a dangerous clot in the lungs) and reduce deaths within 90 days. About 1,800 adult ICU patients expected to stay more than 2 days will…

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…
