Venous Stasis Underlying Cause
Veins are thin-walled vessels that permit the flow of blood in one direction: back to the heart. Tiny valves inside the veins prevent blood flow from reversing direction. Working muscles help pump blood through the veins and back to the heart.
Venous insufficiency is caused by failure of the valves in the veins, which causes blood to go the wrong direction and increases pressure in the lower leg veins. This causes the veins to bulge and prevents more valves from working normally.
Causes of abnormal valves include:
