Surgery using median sternotomy for diffuse aneurysmal disease of the thoracic aorta.

We present our experience using an anterior approach for the replacement of an extensive aneurysm of the thoracic aorta. In recent years we have performed surgery on 20 patients by means of a median sternotomy for aneurysms of the ascending aorta, aortic arch, or descending thoracic aorta. In all but 1 of the patients, a procedure in the ascending aorta was also performed. In some patients a small anterior left thoracotomy at the 4th intercostal space was required to allow the replacement of the aorta as for the diaphragm. Antegrade selective cerebral perfusion (ASCP) according to Kazui's technique was used as a brain protection method. All procedures were performed successfully and the aneurysm was completely resected. No neurologic complications or other major complications occurred. We believe that the anterior approach for extensive thoracic aorta replacement is feasible, allows the use of ASCP, and has shown encouraging results.
