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

This surgery may be needed if you have an aneurysm of the aorta. An aneurysm is a weakened area of the blood vessel. It can cause the blood vessel to bulge out. A large aneurysm may burst and cause severe bleeding.

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, your doctor may ask for:

  • Detailed pictures of your heart and vessels with:     
  • X-rays
  • Echocardiography
  • MRI scan
  • CT scan
  • Angiography
  • Tests of your lung function
  • Your doctor may also ask you 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

    The surgeon will make an incision in your chest. Clamps will be placed on the aorta above and below the aneurysm. The damaged part of the aorta will be removed. A graft will replace the damaged part of the aorta. The graft is a type of man-made tube. It will be stitched into place. Blood will be able to flow through the graft. When the aorta is repaired, the clamps will be removed. Your doctor will look for any leaks.

    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.

    How Long Will It Take?

    2-4 hours

    How Much Will It Hurt?

    Anesthesia prevents pain during surgery. You will be given pain medication to help manage pain during recovery.

    Average Hospital Stay

    The usual length of stay is 7 days. If you have any problems, you may need to stay longer.
