What is an aortic aneurysm?
The aorta is the largest artery in the body which carries oxygenated blood from the heart to the body. The portion of artery which lies deep inside the abdomen is called the abdominal aorta. An aneurysm is a weakened, bulging area in the wall of aorta.
The aorta is under constant pressure as blood is expelled from the heart. With each heartbeat, the walls of the aorta expand and then spring back, exerting pressure on the vessel wall. Over time the wall of the artery may become weak and the pressure from the blood pumping through causes the wall to bulge out, usually at a weak spot in the wall of the blood vessel.
The weakening and the bulging of the abdominal wall artery is called Abdominal Aortic Aneurysm (AAA or “triple A”).
