[A clinical investigation of Bentall's operation for annuloaortic ectasia in the elderly].

Although Bentall's operation has become a routine procedure for annuloaortic ectasia (AAE), few reports on its effects on operative mortality in elderly patients have been published. The results of Bentall's operation for AAE on 4 elderly patients were reviewed. There were two males and two females in the series. The ages ranged 71 to 77 years with an average of 73. The etiology of aneurysms was syphilitic in three and arteriosclerotic in one patients. All patients had AAE, aortic regurgitation and ascending aortic aneurysms. Of all these patients, 1 had a subacute Type A dissecting aneurysm, 1 had a proximal arch aneurysm and 1 had an aortic arch aneurysm plus a sacciform descending aortic aneurysm. All patients had composite graft replacement with coronary reimplantation. Three patients received the concomitant operative procedures including aortic arch replacement and CABG to right coronary artery with saphenous vein graft. All patients survived operation. Postoperative CTR and NYHA classification showed remarkable improvement and serious complications were not found in spite of old age. In the late postoperative period, all patients were alive and well from 4 to 6 years after operation. Bentall's operation can be performed in elderly patients with AAE.
