Among 212 patients undergoing operation for aortic aneurysm and aortic dissection between January 1979 and January 1992, 97 were operated on for aneurysms. The aneurysms were localized in: ascending aorta in 46 patients, transverse aortic arch in 8, descending aorta in 8, thoracoabdominal aorta in 8, abdominal (infrarenal) aorta in 21, descending and abdominal aorta in 2, ascending and thoracoabdominal aorta in 2, ascending and descending in 1, ascending, transverse arch and descending aorta in 1. Hospital mortality was 14,4% being 27,7% (5/18) among patients over 70 years old an 11,3% (9/79) among patients under 70 years of age. Our experience suggests that: secondary and tertiary operations, advanced age, associated diseases, respiratory infection and acute renal failure increase early mortality.
