The VNUS Closure procedurehas become a usefulalternative method for the treatment of varicose veins. Vein Closure can usually be used to treat those patients who would have previously been treated by vein stripping. Closure of the greater saphenous vein is the minimally invasive alternative to vein stripping. Instead of stripping the vein, the Closure device seals the vein shut.

Vein Closure is not a procedure for every varicose vein or every patient with varicose veins. Phlebologists use the Closure procedure most often to close suitable great saphenous veins. The use of the Closure process has now been extended to treat several other veins such as anatomically suitable short (lesser) saphenous veins, anterior accessory saphenous veins, and some perforator veins. Usually the GSV cannot be seen with the naked eye by simply looking at the leg of a patient with varicose veins. Often it is the source of many of the varicosities in the affected leg. Its location and the role it plays in varicose vein formation can be shown with ultrasound examinations. The greater saphenous vein is located on the inside of the thigh. The vein starts at the groin and goes down the inside of the thigh and leg to the ankle.
