Signs and symptoms that your aortic aneurysm has burst include: 1  Sudden, intense and persistent abdominal or back pain. Tobacco use is a strong risk factor for the development of an abdominal aortic aneurysm. 2  The longer you've smoked or chewed tobacco, the greater your risk. 3  Atherosclerosis. 4  Atherosclerosis, the buildup of fat and other substances that can damage the lining of a blood vessel, increases your risk of an aneurysm.
