Comparing two catheters for treating varicose veins with radiofrequency
Part of Heart & circulation clinical trials.
This trial compares two types of catheters (Xianrui Da and Medtronic) used in a minimally invasive procedure called radiofrequency ablation to treat varicose veins. The study looks at how well each works, how safe they are, and which is more cost-effective for patients with moderate to advanced varicose veins.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You have been diagnosed with varicose veins in one leg, and the veins are at a stage C2 to C5 (visible veins with or without skin changes, but no open ulcers).
- An ultrasound shows that the main vein in your thigh (great saphenous vein) has blood flowing backward for more than one second.
- The same ultrasound shows that the diameter of that vein is between 3 and 12 millimeters when you lie down.
- You are not pregnant or breastfeeding, have no blood clots in your legs or history of blood clots, and have not had previous varicose vein treatment on that leg.
- You are able to provide informed consent and attend follow-up visits.

This study compares two minimally invasive treatments (radiofrequency ablation and microwave ablation) for varicose veins in the small saphenous vein. If your varicose veins cause symptoms like pain, swelling, or heaviness, this trial may help determine which treatment works better.
This study looks at how much pain people feel during a microwave treatment for varicose veins in the leg. It aims to understand what factors affect pain, so the treatment can be more comfortable for future patients.
This study tests whether treating nearby varicose veins at the same time as the main vein is as safe and effective as treating them in a separate procedure later. It aims to reduce the number of treatments you might need.
This study looks at whether treating varicose veins in the legs can help reduce knee pain in people 80 years and older. If you have varicose veins and knee pain, this could show if vein treatment is a good option for you.
This study looks at whether treating varicose veins in the legs can help relieve knee pain. If you have varicose veins and have had knee pain for at least 4 weeks, you may be able to join.
This study tests whether a procedure called radiofrequency ablation (using heat to close faulty veins) is safe and effective for people aged 80+ with chronic venous insufficiency. It aims to relieve symptoms like leg swelling, skin changes, or ulcers.
