Aortoiliac occlusive disease is a type of vein condition in the legs. It occurs when the iliac artery that brings blood to your legs becomes narrow or blocked by plaque. Symptoms can include pain, numbness, or cramping in the lower limbs, gangrene in the feet, and erectile dysfunction (ED) in men. Common treatments for aortoiliac occlusive disease include drugs, exercise, and surgery.

It happens when your aorta and iliac arteries become narrow or blocked by:
As plaque builds up, it causes the arteries to narrow and harden, slowing — and even stopping — blood flow.
Atherosclerosis — or hardening of the arteries — is a leading cause of aortoiliac occlusive disease.
Some risk factors for atherosclerosis include:
Another cause can include radiation to the pelvis. This may lead to inflammation in the arteries and progression of PAD.
Aortoiliac occlusive disease develops over a lifetime with varying symptoms.
