One of the most common causes of arterial insufficiency is atherosclerotic disease.


Arterial insufficiency can affect many different parts of the body. The specific symptoms may indicate which artery is involved.

If heart arteries are involved, it can cause symptoms of heart attack.

If brain arteries are involved, it can cause symptoms of stroke.

If the arteries of the lower abdomen or legs are involved, you might have repeated episodes of leg cramping when you walk.

Arterial insufficiency also can affect the arteries in the abdomen, causing pain after you eat meals.
