Radiofrequency Ablation

How does radiofrequency ablation (VNUS Closure) work?

Recently, radiofrequency ablation (also called VNUS Closure or VNUS Fast), has been used to treat leaking saphenous veins (which feed the visible varicose veins) by delivering microwave energy through a small puncture in the leg to close the diseased vein. This technique avoids surgical removal of the vein and an incision in the groin or behind the knee is not required. It avoids some of the bruising inherent in conventional surgery and the recovery is usually a little quicker The procedure may be undertaken using local or general anaesthetic, depending on how extensive your varicose veins are. It is not suitable for all patients with varicose veins.

A thin specialy designed electrode is inserted into the great or small saphenous vein along your leg. Microwave energy is then delivered through the fibre and into the vein, causing the vein to close. The procedure takes about 30 minutes although treatment to visible varicose veins may lengthen the procedure.
