Vein closure is a modern procedure that is done to eliminate varicose veins. The doctor will put a catheter, which delivers radio frequency energy, inside the greater saphenous vein. This energy causes the vein wall to shrink and collapse, hence close the vein. When this vein closes, many nearby veins will also shrink. Vein closure can be done for cosmetic reasons or to relieve the pain caused by varicose veins. Watch this short video to get a good idea of how the vein closure procedure works.
