Abdominal Aortic Aneurysm Repair
by Amy Scholten, MPH
Abdominal aortic aneurysm (AAA) repair is surgery to fix a bulge in the lower aorta. The bulge is called an aneurysm. The aorta is the largest artery in the body. The abdominal part of the aorta carries blood to the abdomen, pelvis, and legs.
Reasons for Procedure
AAA repair is often done when the aneurysm:
Problems are rare, but all procedures have some risk. The doctor will go over some problems that could happen, such as:
AAA surgery for prevention tends to have better outcomes. Emergency AAA surgery has a lower survival rate. This is due to quick blood loss.
Things that may raise the risk of problems are:
What to Expect
The procedure varies. It can be done before a burst—to prevent problems. It can also be done after a burst—as emergency treatment. The preventive procedure is outlined here.
Prior to Procedure
The surgical team may meet with you to talk about
The doctor will give you general anesthesia. You will be asleep.
Description of Procedure
The surgery may be done one of two ways:
An incision is made from the breastbone to below the belly button. The aorta is clamped slightly above and below the aneurysm. Any blood clot inside the aorta is removed. An artificial wall is used to strengthen the area. This is called a graft. The graft will be stitched to the normal aorta on either side. Then, the clamps are removed. The wound is closed with stitches. A bandage will be placed over the site.
A small incision is made in the leg. A stent will be inserted in this incision and into the aorta. It will be moved to the aneurysm. The stent will take pressure off the aorta wall. This will prevent it from bulging or leaking. The incision will then be closed. A bandage will be placed over the site.
How Long Will It Take?
About 4 to 6 hours
Will It Hurt?
Soreness is common after the procedure. Medicine and home care help.
Average Hospital Stay
The length of the stay varies. It depends on a person's overall health.
At the Hospital
