RADIOFREQUENCY OCCLUSION (CLOSURE® PROCEDURE)

The Closure® procedure is a treatment alternative to surgical stripping of the greater saphenous vein. A small catheter is inserted, usually through a needle stick in the skin, into the damaged vein. The catheter delivers radiofrequency energy to the vein wall, causing it to heat. As the vein warms, it collapses and seals shut. The procedure is generally done in an outpatient or in-office setting. It may be done under local anesthesia. Following the procedure, the catheter is removed and a bandage or compression stocking is placed on the treated leg. The Closure® procedure is FDA approved for the treatment of the greater saphenous vein.
