I have varicose veins and my doctor says I should undergo endovenous laser treatment? Can you explain to me what this involves?

EVLT is a relatively new method developed to treat varicose veins. The procedure is done by inserting a thin laser fiber into the vein around the thigh. The laser fiber is then inserted all the way up the groin and turned on. The heat generated then destroys the vein. The laser fiber is gently pulled as it is pulled out and the entire thigh vein is destroyed.
