Veins do not grow back after treatment. At PRK Hospitals, we have two common ways to treat varicose veins. The first is a minimally invasive laser treatment where we treat the vein through just a needle and a catheter. The second treatment option is open surgery where we make small cuts in the leg to physically remove the veins. Both of these procedures are very effective. More often than not, if veins do come back, they typically present years later and these are new varicose veins from alternate pathways since the initial vein was removed.
