A thoracic aortic aneurysm repair is a surgery to fix a problem in the aorta. The aorta is the largest blood vessel in the body. It starts at the heart and passes down through the chest and abdomen. The thoracic aorta is the part of the aorta in the chest. The aorta carries blood from the heart to blood vessels that supply the lower body.

This is a major surgery.

Reasons for Procedure

An aneurysm is a weakened area of the blood vessel wall. If the aneurysm is large or continues to grow it can make the blood vessel break open. In large blood vessels, this can lead to severe bleeding. A thoracic aneurysm is a weakening of a large blood vessel in the chest called the aorta. Blood passes from the heart to the rest of the body through the aorta. A break in this blood vessel is often fatal.

Surgery may be done if there is a thoracic aortic aneurysm that is large or increasing in size.

Possible Complications

Your doctor will review potential problems, like:

  • Adverse reaction to anesthesia, such as lightheadedness, low blood pressure, and wheezing
  • Soreness in throat
  • Nausea and vomiting
  • Infection
  • Excess bleeding
  • Irregular heart rhythm
  • Kidney damage if blood flow is blocked
  • Heart attack
  • Stroke
  • Paralysis if the spinal cord is damaged

Smoking and heavy alcohol use may increase the risk of problems.

Talk to your doctor about these risks before the procedure.

What to Expect

Prior to Procedure

Before surgery you will be examined and you may also have:

  • Tests of your lung function

Your may also be asked to:

  • Stop eating or drinking anything after midnight the night before your surgery.
  • Stop taking some medications up to 1 week before the procedure.

Let your doctor know about any medications or supplements you may be taking.


General anesthesia will be used. It will block pain and keep you asleep during the surgery.

Description of the Procedure

This may be done as an open surgery or using an endovascular approach.

For the endovascular repair, a small incision will be made in your leg. A sleeve will be inserted in this incision and into the aorta. It will be advanced to the aneurysm. The sleeve will take pressure off the wall and prevent it from expanding or leaking. If you need additional heart surgery, it may be done at this time. The incision will then be closed.

In some cases, open surgery may be needed. An incision will be made in the chest. The ribs will be spread. The weakened area of the aorta will be replaced with a graft. The graft will be sewn into place. Blood will be able to flow through the graft. If you need additional heart surgery, it may be done at this time. The chest incision will then be closed with stitches or staples.

Immediately After Procedure

After the operation, you will be taken to the recovery room. Your heart, blood pressure and other vital signs will be monitored.
