What is the difference between chronic venous insufficiency and peripheral vascular disease?

Artery and vein: Venous insufficiency is a disease of the vein which drains blood out of the legs. Periferal vascular disease is a disease of the artery which delivers blood to the legs.

PAD VS. CVI: Peripheral vascular disease, more recently referred to as peripheral arterial disease (pad) , includes diseases that affect the delivery of blood to the extremities. Veins return blood to the heart and lungs. Chronic venous insufficiency when valves within the veins fail, allowing blood to pool in the legs.

Different vessels : Pad involves disease of arteries. Venous insufficiency is problem of veins with leaky valves.

BIg difference: Both involve vessels that carry blood. Chronic venous insufficiency (cvi) affects veins, peripheral vascular (arterial) disease (pad) affects arteries. Both mean that blood isn't getting through the vessels properly. With cvi, the problem is that the inside of the veins carrying the blood becomes too large. With pad, the problem is the inside of the arteries carrying the blood becomes too small.

Vein vs Artery: Chronic venous insufficiency is disease of the veins. The veins bring blood back to the heart. Peripheral vascular disease is also known as peripheral arterial disease. The arteries are vessels that take blood away from the heart. Typically a person only suffers from one of these problems! the patients that suffer from both are more difficult to treat.
