OVERVIEW

Varicose veins are abnormally enlarged superficial veins usually seen in the thigh and leg. In many patients they are a sign of a more serious underlying problem of the venous system. These veins often are branches of the superficial set of veins (long and short saphenous veins), which have leaking valves. As many as 30 million adults in the USA are affected by significant superficial venous insufficiency (saphenous vein and branches) and may have an easily treatable problem.
