Résumé
Since arteriosclerosis is a general progressive disease, an aneurysm of the thoracic aorta is not infrequently complicated by ischemic heart disease. Therefore, assessment of indications of surgical treatment and selection of the surgical procedure and auxiliary procedures on the basis of accurate preoperative evaluation of ischemic heart disease are considered to be very important for improving the results of operations for thoracic aortic aneurysm. Recently. we successfully operated on a 64-year-old patient with a left ventricular aneurysm and a descending aortic aneurysm. One-stage operation was performed by a left thoracotomy approach and partial left heart bypass by draining the pulmonary artery into the femoral artery with mild hypothermia. The approach and the auxiliary procedures employed in this patient are considered to be a useful combination applicable also to one-stage operation for descending aortic aneurysm and coronary artery bypass grafting.
