Veins are vessels, as well as arteries and lymph vessels; belonging to a circulation system. Veins bring used blood back to the heart. When veins do not function properly, condition known as “venous insufficiency” may develop.

This disease most commonly affects lower extremities.  Under normal circumstances, blood in our legs is moving upstream toward the heart. Since the blood flow is directed against the forces of gravity, presence and appropriate function of venous valves are essential for the normal circulation.
