Chronic venous insufficiency


Venous insufficiency involves one or more veins. Valves in the veins usually push the flow of blood toward the heart. When these valves are damaged, the blood leaks and pools in the legs and feet. The condition may also be caused by a blockage in a vein from a clot (deep vein thrombosis).

Chronic venous insufficiency is a long-term condition. It occurs because of partial vein blockage or blood leakage around the valves of the veins.
