Why is an abdominal aortic aneurysm (AAA) repair performed?

Open repair of an abdominal aortic aneurysm (AAA) -- a bulging, weakened area in the wall of the aorta (the largest artery in the body) -- involves an incision of the abdomen to directly visualize the aortic aneurysm. Reasons an abdominal aortic aneurysm (AAA) repair may be performed include, but are not limited to, the following:
  • To prevent the risk of rupture
  • To relieve symptoms
  • To restore a good blood flow
  • Size of aneurysm greater than 5 centimeters in diameter (about two inches)
  • Growth rate of aneurysm of more than 0.5 centimeter (about 0.2 inch) over one year
  • When risk of rupture outweighs the risk of surgery
  • Emergency life-threatening hemorrhage (uncontrolled bleeding)
There may be other reasons for your physician to recommend an abdominal aortic aneurysm repair.
