SURGICAL REPAIR FOR AORTIC ANEURYSMS IN AGED PATIENTS OVER 70 YEARS OF AGE

From 1960 through 1991, 556 consecutive patients with aortic aneurysms consisting of 173 with abdominal aortic aneurysms (AAA) and 383 with thoracic aortic aneurysms (TAA) were treated surgically. No significant differences were observed in the early mortality rate after AAA or TAA repair between the aged (41 TAA, 52 AAA) and non-aged groups. The 5-year survival rate of aged patients with TAA (47.3±8.5%) was significantly lower to that of non-aged patients (67.4±2.8%).
However, the 5-year survival rate of aged patients with AAA (63.9±12.1%) was not singificantly different from that of non-aged patients (75.9±4.3%).
The asymptomatic non-ruptured aneurysms in aged-patients present many problems such as the association between surgical intervention and life expectancy, selection of patients by accurate preoperative evaluation of risk factors, and determination of the timing of operation.
