Endovenous Laser Ablation Treatment Endovenous Laser Ablation Treatment (EVLA) uses laser light to seal the diseased vein shut. Using a small needle, a laser fiber is inserted directly into a varicose vein and is carefully positioned using the assistance of ultrasound. Precise, rapid pulses of laser light heat up the inside of the vein causing it to close off.
EVLA is done in the clinic under local anesthesia and physical activity is encouraged after the procedure. In fact, many patients will drive to work and finish their shifts after EVLA without the help of pain medication!
