OBJECTIVE: Assessment of mortality and long-term relative survival following repair of asymptomatic abdominal aortic aneurysms. DESIGN: Retrospective review. SETTING: University Hospital. MATERIALS: Three hundred and twenty seven patients with a median age of 68 years and male to female proportion of 10:1. CHIEF OUTCOME MEASURES: Operative mortality and long-term mortality obtained from Norwegian Registrar's Office. Demographically matched expected survival calculated from death rate tables published by the Norwegian Central Bureau of Statistics. MAIN RESULTS: The overall operative mortality was 5.2%. Ten-year survival rate for all the patients was 38% compared to the expected of 52%. The standard mortality rate was 1.30, indicating a 30% higher mortality compared to a demographically matched population. Older patients and patients with known cardiac disease had significantly increased operative mortality. These patients also had the lowest long-term survival. Patients with cardiac disease suffered a postoperative mortality more than two times expected. CONCLUSIONS: Further studies are needed to define subgroups unsuitable for elective surgery.
