Endovenous Laser Varicose Vein Surgery - Hopkins Medicine
Varicose veins are swollen, bulging veins that often happen on the thighs or calves. A laser is a device that sends a thin beam of radiation in the form of light. Laser surgery closes and shrinks the varicose vein and causes scar tissue within the vessel. This seals off the vein. Blood then flows through other nearby veins instead.
