Thoracic Aortic Aneurysm Open Repair

The type of surgical repair of a thoracic aortic aneurysm will depend on several factors: the location of the aneurysm, the type of aneurysm, and the patient's tolerance for the procedure. For an ascending or aortic arch aneurysm, a large incision may be made through the breastbone (median sternotomy). If an ascending aneurysm involves damage to the aortic valve of the heart, the valve may be repaired or replaced during the procedure. For a descending aneurysm, a large incision may extend from the back under the shoulder blade around the side of the rib cage to just under the breast (thoracotomy). These approaches allow the surgeon to visualize the aorta directly to repair the aneurysm.
