 note = {An analysis was undertaken to clarify the significance of aodominal aortic aneurysmectomy in patients aged over 70 years. From July 1981 to December 1995, fourty-two patients aged over 70 years (mean age, 74 years) were admitted for surgery. The patients consisted of 36 males and 6 females. Aneurysmal diameter ranged from 4.5 cm to 10 cm (mean 7.0 cm). Five patients had a ruptured aneurysm. Preoperative complications such as hypertension, ischemic heart disease, cerebral infarction and respiratory dysfunction were observed in 29 (69 %), 11 (26 %), 7 (16 %) and 5 (11 %), respectively. Postoperative complication occurred in 9 (21 %) patients. Hospital death occurred in 2 (5 %) and late death in 13 (31 %) patients. Complete postoperative information was obtained in all patients. The 1, 5, and 10 year survival rates were 97 %, 68 %, and 42 %, respectively. The postoperative survival curve was similar to that of Japanese males aged of 75 years. In conclusion, good outcome would be expected in patients with abdominal aortic aneurysm when appropriate surgical management is carried out.},
