The aorta is the largest artery in the body. The abdominal portion of the aorta carries blood to the abdomen, pelvis, and legs. Sometimes the walls of the aorta weaken and bulge in one area. This is called an abdominal aortic aneurysm (AAA). AAAs are most often caused by
atherosclerosis, also known as hardening of arteries, and
high blood pressure.

Reasons for Procedure
Surgery to repair an AAA is often done when the aneurysm:
- Causes physical symptoms such as abdominal pain
- Reaches a size of five centimeters (2 inches) across or has been growing rapidly. Smaller aneurysms are watched closely. They are rarely repaired with surgery.
- Has burst—Surgery must be done right away.
Preventive AAA surgery generally has a good outcome for people who are relatively healthy. Emergency surgery to fix an AAA rupture has a much lower survival rate, due to the rapid loss of blood.
Your doctor will review a list of possible complications, which may include:
- Problems from
general anesthesia, including lightheadedness, low blood pressure, and wheezing
- Damage to organs
Some factors that may increase the risk of complications include:
What to Expect
The procedure varies. It can be done before a rupture as a preventive measure or after a rupture on an emergency basis. The preventive procedure is outlined here.
Your doctor may need detailed pictures of your abdomen, heart, and lungs. These can be made with:
Your doctor may also need a record of your heart activity. This can be made with an
Your doctor may ask you to see a cardiologist—a doctor who specializes in heart conditions. The cardiologist will check your heart before surgery.
Before the procedure:
You may need to stop taking certain medicines one week before surgery. Talk to your doctor about your regular medicine, especially:
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Blood-thinning drugs
- Anti-platelet drugs
On the day of the procedure, you will be given an antibiotic by IV. You may also be given a laxative or enema to clear out your bowels.
will be used. It will block any pain and keep you asleep through the surgery. It is given through an IV.
In most cases, an incision is made from the breastbone to below the belly button. The doctor clamps the aorta slightly above and below the aneurysm. Any blood clot on the inside of 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.

Anesthesia prevents pain during the procedure. Most people will be sore after the procedure and will be given pain medicines.
The length of your hospital stay depends on your overall condition. Ask your doctor how long you should plan to stay.
While you are recovering at the hospital, you may receive the following care:
- You will be sent to the intensive care unit for monitoring.
You will have tubes in place, which may include the following:
- IV—provides medications and fluids
- Urinary catheter—monitors urine output
- Arterial catheter—monitors blood pressure
- Central venous catheter—monitors pressure in the heart
- Epidural catheter—provides pain medicine
- Nasogastric tube—inserted through the nose and into the stomach to remove secretions and provide nutrition until your intestines regain normal function
When you return home, do the following to help ensure a smooth recovery:
to care for the wound.
- Gradually return to your normal activities.
- To help prevent further problems, you and your doctor will need to work to increase your overall health. Atherosclerosis and high blood pressure should be managed carefully. This can be done with medicines and a healthy lifestyle. If you are a smoker, you should talk to your doctor about quitting.
Also, ask your doctor about when it is safe to shower, bathe, or soak in water.
Call Your Doctor

- Redness, swelling, increasing pain, excessive bleeding, or discharge at the incision site
- Signs of infection, including fever and chills
