The risks and benefits of surgery for abdominal aortic aneurysms differ from those for thoracic aortic aneurysms.

Abdominal aortic aneurysms are unlikely to rupture if they develop slowly, are less than 4 or 5 centimeters (about 2 inches) in diameter, and cause no symptoms. In these cases, the risk of rupture within a five-year period is low and observation with periodic rechecks of the aneurysm is often advised. The risks from surgery outweigh the risk of the aneurysm rupturing.

If surgery is required, the weakened aorta is replaced with a polyester tube and sutured in place. The polyester graft is permanent and will last for many years. This proven method has been used at Mayo Clinic for many years.

Repair of these aneurysms can usually be accomplished with traditional abdominal surgery or with newer endovascular surgical techniques.
