Outcome and Survival of Patients Aged 65 Years and Younger after Abdominal Aortic Aneurysm Rupture

Advanced age (> 80 years) confers a survival disadvantage after operative repair of a ruptured abdominal aortic aneurysm (AAA). This study aimed to determine if young age (≤65 years) confers a survival benefit. Consecutive patients undergoing attempted repair of a ruptured AAA between 1995 and 2001 were included in the study. Demographic, clinical, and operative factors were analyzed together with in-hospital mortality, duration of postoperative hospital stay, and long-term survival. Of 378 patients admitted with a ruptured AAA, 52 (14%) were ≤ 65 years of age and 326 (86%) were > 65 years. There were 4 (8%) women in the younger cohort compared to 74 (23%) women in the older group (p = 0.015). Four (8%) patients in the younger group were thought to be unsuitable for surgical repair compared to 77 (24%) patients in the older cohort (p = 0.009). Of the 48 younger patients who underwent attempted operative repair, 22 (46%) died in hospital, compared to 108 (43%) of 249 patients > 65 years (p = 0.753). The median (range) postoperative hospital stay of survivors was 11 days (6–59 days) in the younger cohort and 15 days (6–121 days) in the older group (p = 0.005). Patients ≤ 65 years of age undergoing operative repair of ruptured AAA have no survival advantage over older patients. These data support AAA screening for the “at risk” and age-defined population.
