[Total aortic arch graft replacement using a prosthetic graft with three branches for acute type A aortic dissection].

Between March 1991 and August 1991, six consecutive patients underwent the replacement of the both ascending aorta and total aortic arch using a prosthetic graft with three branches for acute type A aortic dissection involving the aortic arch. Preoperative complications included cardiac tamponade in 5 cases, aortic regurgitation in 2, and shock state in 3. All operations were performed with the aid of extracorporeal circulation, selective cerebral perfusion, and open aortic anastomosis within 3 days after the onset. One patient died of rupture of the aortic anastomosis secondary to mediastinitis two weeks after the operation. All patients gained their own consciousness after the operation without any serious cerebral complications. The present data suggest that acute type A aortic dissection involving the aortic arch could be treated by replacing both the ascending aorta and aortic arch using a prosthetic graft with three branches with an aid of the extracorporeal circulation, selective cerebral perfusion and open distal anastomosis.
