Two ways to treat enlarged veins in your leg
Part of Heart & circulation clinical trials.
This study compares two minimally invasive procedures to treat enlarged great saphenous veins (a vein in your thigh that can cause swelling, pain, or skin changes). Both procedures seal off the problematic vein by either using heat and mechanical motion or injecting a foaming substance.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your vein problems must be visible (like swelling, discoloration, or skin changes) or cause symptoms—confirmed by ultrasound
- Your great saphenous vein must be enlarged but not too large: between 6–12 millimeters in diameter
- You cannot be allergic to sclerosing medications (drugs used to shrink veins)
- You have not had recent blood clots, strokes, or lung clots
- You are not pregnant and do not have a severe leg artery disease
- You cannot have an active infection or be on prolonged bed rest

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 compares two ways to treat varicose veins: doing a heat-based treatment (radiofrequency ablation) on the main thigh vein at the same time as treating the smaller branch veins, or treating the branch veins later. It aims to find which approach works better and is safer for people with mild to moderate varicose veins.
This study compares two different catheters used in a procedure called radiofrequency ablation to treat varicose veins. The goal is to see which catheter works better, is safer, and is more cost-effective.
This study compares two surgical approaches for treating advanced varicose veins, one using a small camera and the other using traditional open surgery. The goal is to see which method provides better results with fewer complications.
This study looks at whether treating varicose veins in the legs can also help reduce knee pain in older adults (80+). If you have both varicose veins and knee pain, this treatment may offer relief.
This study compares two treatments for small, visible leg veins (spider veins and slightly larger blue or green veins). It tests whether using a laser along with foam sclerotherapy (a medicine injected into the veins) works better than foam alone.
