LASER TREATMENT FOR VARICOSE VEINS has helped thousands of people to overcome their varicose veins pain! Using ultrasound guidance, a tiny fiber-optic probe is inserted into the varicose vein through the catheter. This probe transmits laser energy to the affected vein. The heat from the laser kills the tissue in the varicose vein, causing the vein to close and eventually be reabsorbed by the body.
