Endolaser Vein Therapy is an office-based procedure designed to replace the old-fashioned vein stripping. With ELVeS, a thin laser fiber, guided by ultrasound, is inserted into the GSV or SSV. After local (tumescent) anesthesia, laser energy is delivered to the diseased vein. This causes the truncal vein to close and eliminates the reflux. Subsequently, the branching varicose veins on the surface of the skin collapse. Those veins that do not collapse completely may be treated with sclerotherapy or ambulatory phlebectomy. Graduated compression is needed post-treatment. There is no "down time" as patients are up and on their feet immediately and instructed to ambulate on a daily basis.
