Abdominal Aortic Aneurysm
What Is It?
An abdominal aortic aneurysm is an abnormal swelling in the aorta. Smaller aneurysms rarely cause a problem. But over time, they can enlarge, which increases the risk of rupture. This can be fatal.
The aorta is the body's largest artery. It carries oxygen-rich blood from the heart to smaller arteries in the body.
