Between January 1994 and October 2004, 87 patients underwent emergency thoracic aortic surgery. Of these, 11 patients were more than 80 years old (O-group) and 76 were less than 80 years old (Y-group). A total of 58 patients (6 in O-group and 52 in Y-group) were treated for acute type-A aortic dissection, 5 (0 in O-group and 5 in Y-group) for acute type-B aortic dissection and 21 (4 in O-group and 17 in Y-group) for the involved rupture of a thoracic aortic aneurysm. The operative procedures consisted of the replacement of either the ascending, or the ascending and transverse aorta in 71 patients (8 in O-group and 63 in Y-group), and the replacement of the distal descending aorta in 15 patients (3 in O-group and 12 in Y-group). The operative mortality rates were 27.2% (3 patients) and 19.7% (15 patients) in the O- and Y-groups, respectively, with no significant difference between the groups. The rate of early complications, including circulatory failure, respiratory failure and cerebral infarction, did not statistically differ between the 2 groups. The overall 2-year survival rates of the patients who survived the operation were 83.3% in the O-group and 95.1% in the Y-group. Moreorer, 75% of the patients (6 of 8) who survived the surgery regained normal activities of daily life after the surgery, at a level similar to before the surgery. The present data indicates that emergency thoracic aortic surgery can be justified in selected in octogenarian patients.
