Arteries such as the aorta can become blocked by fat and cholesterol plaque deposits. These deposits thin the walls of the artery and slow the flow of blood, explains WebMD.com.

This loss of circulation, if not treated in time, can lead to the loss of the limb.

A blockage in the abdominal aorta can also lead to an aneurysm. If an aneurysm, which is a bulge or inflation of the wall of an artery, is not treated in time, it can expand, notes WebMD.com. Artery walls are thin and fragile. If this happens, they can burst, leading to a rupture in the aneurysm. A rupture or leak in an abdominal aorta aneurysm can be a life-threatening condition as it involves internal bleeding.
