Perforator veins serve as connections between the two networks of veins in the extremities, the superficial venous system and the deep venous system. Perforators connect the two parallel systems, somewhat like the rungs of a ladder connect the side rails, and normally drain blood from the superficial veins to the deep veins as part of the process of returning oxygen-depleted blood to the heart.
Perforator veins have one-way valves designed to prevent backflow of blood towards the superficial veins. When those valves no longer function properly , reflux occurs, and can enlarge the perforators and the superficial veins they lead to.
Perforator veins in the lower leg and ankle are particularly vulnerable to distention and incompetence, and the resultant circulatory problems create an increased likelihood of edema, skin discoloration, dermatitis and skin ulcers in the immediate area.
Like primary superficial veins that become incompetent, perforator veins can be treated by the doctors of Vegas Valley Vein Institute. Abnormal perforator veins will be diagnosed by ultrasound in the office.
