Definition Return to top
Endovascular abdominal aortic aneurysm repair is surgery to fix a widened part (or aneurysm) in your aorta, the large artery that carries blood to your belly, pelvis, and legs.
An aortic aneurysm is when a part of this artery becomes too large, or balloons outward, due to weakness in the wall of the artery.

You will lie down on a padded table in an operating room, in the radiology department of the hospital, or in a catheterization lab. You may receive general anesthesia (asleep and pain-free) or epidural or spinal anesthesia.

You may have an abdominal aortic aneurysm that is not causing any symptoms or problems. Your doctor may have found out about this problem from special tests called an ultrasound or CT scan. There is a risk that this aneurysm may open up (rupture) if you do not have surgery to repair it. However, surgery to repair the aneurysm may also be risky.
You and your doctor must decide whether the risk of having this surgery is smaller than the risk of bleeding if you do not have surgery to repair the problem. The doctor is more likely to recommend you have surgery if the aneurysm is:
