What is the maximum diameter of GSV that EVLT can successfully treat?

With generous tumescent anesthesia and proper position of the patient, probably up to 1.5 centimeters or 15 mm Greater Saphenous Vein can be successfully closed with an EVLT. However, the larger the Saphenous vein, after you get above 1 cm or 10 mm the chance of success goes down a little. The reflux in the Femoral Vein is a separate problem, and it does not make the treatment of the Saphenous Vein less successful. Any surgical procedure has a chance of a blood clot. A blood clot complication occurs which is rare, less than 1,000 can occur. If a blood clot complication occurred, there is a chance it could\ make deep vein function worse.
