title: Extended and total aortic resection in the surgical treatment of acute type A aortic dissection: experience with 54 patients.
abstract: Fifty-four patients with acute type A aortic dissection were surgically treated with extended aortic resection. The age of the patients ranged from 22 to 75 years, and all of them were in very critical condition. In 50 patients, the resection extended from the aortic valve (included in 33) to the beginning of the descending thoracic aorta and in 4, from the valve (included in 3) to the aortic bifurcation. Deep hypothermia and circulatory arrest were employed during the aortic arch resection; inclusion of the graft at the end of procedure was done in 44 patients; in the others, the diseased aortic wall was excised. Early mortality was 20 +/- 6% (11/54). Nine deaths were due to persistence of the distal dissection. Acute type A aortic dissection with aortic valve insufficiency should be treated as an emergency with extended aortic resection. As far as control of bleeding and closure of distal dissection are concerned, the best results have been achieved when the diseased aortic wall has been completely excised.
