Venous insufficiency is a condition that occurs when blood moving up the legs and back toward the heart escapes back down the veins and increases the blood congestion already in the legs. Venous insufficiency is caused by malfunctioning valves in the high-pressure deep veins, low pressure superficial veins, or both.
Symptoms of Venous insufficiency include pain, swelling, skin changes, and even tissue breakdown. With no valves to prevent backflow of blood, Venous Insufficiency can cause dramatically increased venous pressure in the lower extremities.
