Abdominal aortic aneurysm resection in patients more than 80 years old.
Improvement in anesthetic and surgical techniques has prompted a more aggressive approach to repair of abdominal aortic aneurysms in patients more than 80 years old. In order to determine if surgical treatment is justified, all of the patients who were more than 80 years old admitted to the hospital during the ten year period from 1974 to 1983 with the diagnosis of abdominal aortic aneurysm were reviewed. A total of 90 patients were available for analysis. The mortality of the 18 patients treated conservatively for ruptured aortic aneurysms was 100 per cent. Ten of the 27 patients operated upon for a ruptured aneurysm died yielding a mortality of 37 per cent. Eleven patients with symptomatic aneurysms had urgent repair with a mortality of 27 per cent. Only one of the 34 patients undergoing elective aneurysm repair died. There was no difference in the size of aneurysms among the groups. Although the ruptured aneurysms required more blood (10.2 +/- 3.7 units), there was no difference between the other two groups (symptomatic 4.5 +/- 3.1 units, elective 4.6 +/- 2.8 units). There was significantly fewer myocardial and renal complications in the elective group, although the sole death in this group was from myocardial infarction. Based upon these observations, we recommend aggressive elective therapy for selected patients who are more than 80 years of age with asymptomatic abdominal aortic aneurysms. Although the mortality is higher in those patients with symptomatic or ruptured aneurysms, it is not formidable, and therefore, repair should not be ruled out on the basis of age alone.
