Venous insufficiency

This study tests a special stent (a small mesh tube) placed in veins to treat blockages, narrowing, or leg ulcers caused by poor blood flow. About 150 adults will receive the stent and be followed to see if it keeps the vein open and safe. The goal is to improve blood flow and re…

This study tests whether shining a special low-level laser on chronic leg ulcers can help them heal faster. 96 adults with venous leg ulcers will receive either real laser treatment plus standard compression, or a sham laser plus compression, twice a week for 16 weeks. The goal i…

This phase 3 trial tests whether a daily tablet of CLR-07-23 (heparan sulfate) can reduce symptoms of chronic venous disease, such as leg pain, itching, swelling, and night cramps. The study includes adults aged 18 to 80 with mild to moderate vein disease. Participants take eithe…

This trial tests a new device called the enVVe system, a catheter-based artificial valve placed in leg veins to treat chronic venous insufficiency. The study will enroll 220 people with severe symptoms like skin changes or leg ulcers. Participants are randomly assigned to receive…

This study compares two treatments for acute deep vein thrombosis (DVT) in the leg. Half of the 104 participants will receive standard blood-thinning medication alone, while the other half will also undergo a procedure to suction out the clot, sometimes with balloon dilation or a…

This study tests whether special dressings made from donated human umbilical cord tissue, used along with standard wound care, can help close hard-to-heal leg ulcers faster than standard care alone. About 272 adults with venous leg ulcers that have not healed after 4 to 52 weeks …

This study tests whether adding colchicine, an anti-inflammatory pill, to standard blood thinners can prevent long-term vein damage after a deep vein thrombosis (DVT) in the leg. About 940 adults with a first acute DVT will receive either colchicine or a placebo for six months an…

This study will test a new way to treat varicose veins using a 1940nm laser, performed outside the operating room under local anesthesia. Researchers want to see how satisfied patients are with the procedure and check its safety and effectiveness. About 155 adults with saphenous …

This study tests whether taking calcium dobesilate before and after radiofrequency ablation for varicose veins can reduce pain and improve quality of life. 250 adults with symptomatic varicose veins will be randomly assigned to receive the drug or standard care. The main goal is …

This study looks at whether a common procedure for varicose veins—called endovenous ablation—can also reduce knee pain in people aged 80 and older. The researchers will follow 50 participants for one year after treatment, measuring pain and knee function. The goal is to see if im…

This observational study will track 87 people who are already scheduled to receive treatment with the Recana Thrombectomy Catheter System for blocked veins in their legs. The goal is to see how safe the device is and how well it works at clearing the blockages during the procedur…

This study tests whether releasing a blood pressure cuff (used as a tourniquet) early during blood collection reduces the rate of hemolysis — when red blood cells burst and ruin the sample. About 792 emergency department patients with non-critical conditions will be randomly assi…

This study will follow 100 people getting a total knee replacement to see if those with chronic venous insufficiency (poor blood flow in leg veins) have more wound healing problems. Participants will have an ultrasound before surgery to check their veins and then be monitored for…

This study will test a specially trained AI model (like ChatGPT) to see if it can help doctors correctly diagnose and recommend treatments for lymphedema, lipedema, and venous insufficiency. Researchers will compare the AI's suggestions to current medical guidelines. The goal is …

This study watches 300 ICU patients to see how often blood clots caused by catheters remain in the vein after the catheter is taken out. Researchers will track risk factors and whether these clots lead to serious issues like lung clots or long-term vein damage. No new treatments …

This study will follow 50 adults with varicose veins and chronic knee pain who are scheduled for standard vein treatment (laser or radiofrequency ablation). Researchers will measure changes in knee pain, stiffness, and function before and after the procedure. The goal is to see i…
