Any impairment of blood flow back to the heart is referred to as venous reflux or venous insufficiency. Occasionally blockage of leg veins, due to blood clots or scarring, may alter normal blood flow. Reflux of the superficial veins is the most common form of venous disease. In superficial venous insufficiency, the deep veins are usually normal. Blood from the deep veins may escape through refluxing perforator veins into the dilated superficial veins causing increased venous pressure in the superficial veins.
