VNUS Closure is a minimally invasive radiofrequency treatment for varicose veins caused by greater or lesser saphenous vein reflux. In many patients it is a desirable alternative to surgery. The procedure is performed in the office under local anesthetic. A small radiofrequency catheter is painlessly inserted into the vein under ultrasound guidance. The fiber is connected to the power source and the vein is then collapsed. A single steri-strip is placed over the catheter entrance site and compression stockings are then worn for one month after the procedure.

Patients may resume normal activity that day and generally return to work the following day. A small number of people may require a subsequent office procedure to obliterate residual varicose and spider veins.
