What are the perforator veins?
Perforator veins are blood vessels that connect the superficial venous system to the deep vein network. These veins allow blood to drain from the skin into the deep veins. The number of perforator veins in each leg is around 150, and their concentration is the highest in the lower part of the leg. When valves inside the perforator veins malfunction, blood is pushed back into the superficial veins causing varicose veins, thread veins, brown stains, and possibly leg ulcers.
