title: Operative mortality and long-term relative survival of patients operated on for asymptomatic abdominal aortic aneurysm.
abstract: OBJECTIVE
  Assessment of mortality and long-term relative survival following repair of asymptomatic abdominal aortic aneurysms.
  
  
  METHODS
  Retrospective review.
  
  
  METHODS
  University Hospital.
  
  
  METHODS
  Three hundred and twenty seven patients with a median age of 68 years and male to female proportion of 10:1.
  
  
  METHODS
  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.
  
  
  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.
