Dr. Gary Jones, surgeon at Louisiana Cardiovascular & Thoracic Institute discusses AAA -- Abdominal Aortic Aneurysm. An aortic aneurysm is a bulge in part of the aorta the body's main artery. When this bulge is in the belly (abdomen), it's called an abdominal aortic aneurysm. It's often called "triple A" for short. These aneurysms happen in about 1 out of 100 men ages 45 to 54. But they occur more often as people get older: up to 12 out of 100 men ages 75 to 84 get them.1 Women are 2 to 5 times less likely than men to have an AAA.These bulges are most common in men older than age 65, people with high blood pressure, and people who smoke. AAAs sometimes run in families. Most aortic aneurysms never cause problems, especially if they're small and don't grow fast. But if the bulge gets too big, it can burst, or rupture, which is often deadly.
