Between October 1990 and September 1994, 79 patients underwent aortic arch replacement for aneurysmal disease in our institution. Fifty-nine patients had a dissection. Type A (43 acute, 16 chronic), and 20 patients (6 acute, 14 chronic) had an aortic diameter of more than 6 cm. The patients age (53 male, 26 female) ranged between 16 and 81 years. Primary diagnosis was hypertension (n = 60), Marfan (n = 8), unknown (n = 10) and trauma (n = 1). Total cardiopulmonary bypass was established via femoral artery cannulation. Cortisone and thiopental were given for added cerebral protection. Deep hypothermia, confirmed by isoelectric-EEG, and circulatory arrest were induced in all patients. The aneurysm was opened longitudinally and a full thickness single patch or island of aortic wall, containing the origins of the three arch vessels, was constructed and anastomosed in a continuous fashion to an albumin pretreated graft.
