Chronic venous insufficiency

This study tests a new medical device called the GORE VIAFORT stent, which is a small mesh tube placed inside a blocked or narrowed vein in the leg or pelvis to keep it open. The goal is to improve blood flow and reduce symptoms like pain, swelling, and leg ulcers. About 165 adul…

This early study tests a new device called the Cook® Venous Valve System in just 4 people with chronic venous insufficiency (leg veins that don't pump blood back to the heart properly). The valve is implanted through a small tube into a deep leg vein to help blood flow one way. T…

This trial is testing a new stent (a small mesh tube) to treat blockages in the large vein in the abdomen (inferior vena cava) and nearby leg veins. The study involves 136 adults with symptoms like leg ulcers, pain, or swelling. Doctors will place the stent to keep the vein open …

This study tests a device that uses radiofrequency energy to close off damaged veins in the legs, helping blood flow better and easing symptoms like pain and swelling. About 200 adults with chronic venous insufficiency are taking part. The main goals are to see if the treated vei…

This study tests whether a device called Sonablate can safely use high-intensity focused ultrasound (HIFU) to treat vein problems like varicose veins, leg ulcers, and certain birth defects. About 30 adults with these conditions will receive the treatment, which does not involve c…

This study tests a special dressing called EDX110 on 43 people with hard-to-heal wounds from diabetes or poor leg circulation. The dressing creates a gas called nitric oxide to help clean and heal the wound. Researchers will measure how much the wound shrinks over 12 weeks and ho…

This study tests whether kinesio taping (a special elastic tape) and interval exercise (short bursts of activity) can help people with mild chronic venous insufficiency feel better and improve their quality of life. About 33 adults aged 18 to 65 will be split into three groups: o…

This study tests whether wearing a virtual reality headset during laser treatment for varicose veins can lower anxiety and pain. About 100 adults will use VR during the procedure, and researchers will measure their heart rate, blood pressure, and comfort levels. The goal is to se…

This study looks at whether adding pelvic floor exercises to a regular exercise program and compression stockings can improve symptoms, blood flow, and quality of life in people with chronic venous insufficiency (a condition where leg veins have trouble sending blood back to the …

This study looks at whether wearing compression stockings for a longer time after foam sclerotherapy (a treatment for varicose veins) can reduce skin darkening (hyperpigmentation) above the treated veins. About 140 adults with varicose veins will be followed for 28 days after the…

This study follows 100 people with and without varicose veins to see how often the condition appears and how it changes over time. Participants get yearly checkups including ultrasound exams. The goal is to learn what factors make vein disease worse and how it naturally progresse…

This study looks at whether a pneumatic compression device can improve lymphatic function in people with leg swelling from chronic venous disease. 34 participants will be split into two groups: one gets standard compression bandages, the other adds daily pneumatic compression at …
