With this type of microsurgery, a special light source marks the location of the vein. Tiny 1 - 2 mm cuts are made in the skin, and surgical hooks pull the vein out of the leg. This surgery requires local or regional anesthesia. The vein usually is removed in one treatment. Very large varicose veins can be removed with this treatment while leaving almost no scars. Patients can return to normal activity the day after treatment.
