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.
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.
Your doctor will review potential problems, like:
Smoking and heavy alcohol use may increase the risk of problems.
Talk to your doctor about these risks before the procedure.
Before surgery you will be examined and you may also have:
Your may also be asked to:
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.
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.
After the operation, you will be taken to the recovery room. Your heart, blood pressure and other vital signs will be monitored.
Anesthesia prevents pain during surgery. You will be given pain medication to help manage pain during recovery.
The usual length of stay is 7 days. If you have any problems, you may need to stay longer.
