Radiofrequency Ablation (RFA), also known as VNUS or ClosureFAST, is a Medicare-approved, minimally invasive technique for eliminating unhealthy veins. RFA uses thermal (heat based) energy to damage the vein, causing it to seal closed. RFA is used to treat major varicose veins and is a safer and more effective alternative to surgery.

Varicose veins are swollen, enlarged veins. They happen most often in the legs. In Radiofrequency Ablation (RFA), the doctor inserts a small catheter into the diseased vein through a small incision, using ultrasound guidance for an accurate and live view. Consistent and uniform heat is delivered to contract the collagen in the vein walls, causing them to collapse and close.

2019-12-02 Radiofrequency ablation closes off varicose veins in about 88 out of 100 people. That means it doesn't work in about 12 out of 100 people. footnote 1. Pain after treatment is typically less after ablation than after vein surgery. Veins that do not close are treated again.

INTRODUCTION. Radiofrequency ablation (RFA) is a minimally invasive percutaneous technique using thermal energy to ablate incompetent veins. The device is used primarily to treat insufficiency of the axial veins (ie, great, small, accessory saphenous veins), but perforator veins can also be treated with a specialized radiofrequency stylet.

Mechanism • Using a bipolar RFA catheter-based approach, generator delivers radiofrequency (RF) energy to the vein … Radiofrequency Ablation (RFA) Treatment for Varicose Veins Getting ready for your treatment. Follow any instructions from your healthcare provider.
