Between January 1979 and December 1989, eighty five operations were performed to treat aortic dissection, including fifty in the acute phase, and thirty five in a chronic phase. The Hospital mortality was 21.1% (eighteen patients) and low cardiac output was the major cause of death. The mortality was higher in the group of patients operated upon in the acute phase. Four patients were operated upon for redissection or dissection in other localization of the aorta, and all of them died. One patient developed paraplegy in the postoperative period. The late follow-up showed good evolution in the survivors group.
