The large part of the aneurysm is close to the aorta descending. Review of the literature indicated that direct aortic replacement in the setting of acute descending aortic dissection continues to carry a very high mortality 28-65 and paraplegia rate 30-35 leaving room for consideration of alternative procedures. Aneurysms that involve the aorta as it flows thru both the abdomen and chest are called thoracoabdominal aortic aneurysms.
The aorta is the largest blood vessel in the body and it delivers blood from the heart to the rest of the body. Aneurysms involving the descending and abdominal aorta are classified as thoracoabdominal aortic aneurysms.
