 | | Surgical treatment of ascending aortic aneurysms depends on the extent of the aneurysm both proximally, ie, involvement of the aortic valve, annulus, sinuses of Valsalva, or sinotubular junction, and distally, ie, involvement to the level of the innominate artery. |
 | | Surgically, descending thoracic aneurysms may be repaired with or without the use of a bypass circuit from the left atrium to the femoral artery or a full cardiopulmonary bypass, depending on the length of the anticipated ischemic cross-clamping and the experience of the surgeon. |
 | | Thoracoabdominal aneurysms, comprising approximately 10% of thoracic aneurysms, may be repaired with the use of a partial bypass of the left atrial artery to the femoral artery. |
