Endovenous laser treatment can treat larger varicose veins in the legs. A laser fiber is passed through a thin tube (catheter) into the vein. While doing this, the doctor watches the vein on a duplex ultrasound screen. Laser is less painful than vein ligation and stripping, and it has a shorter recovery time.
