Perforator veins are so called because they perforate the deep fascia of muscles, to connect the superficial veins to the deep veins where they drain.[1][2]
Perforator veins play an essential role in maintaining normal blood draining. They have valves which prevent blood flowing back (regurgitation) from deep to superficial veins in muscular systole[3] or contraction.
