Who Should Be Operated When Presenting with a Ruptured Abdominal Aortic Aneurysm? A Monocentric Study in a Tertiary Hospital

Mortality with ruptured abdominal aortic aneurysms (rAAAs) is 80% overall, 50% when operated, and 100% when not operated. Distinguishing in emergency patients who should be operated versus being offered palliative treatment is difficult. We sought to identify key factors to consider in this decision-making. Between 2001 and 2014, we selected all consecutive patients with rAAA treated by open or endovascular procedures in a tertiary hospital for inclusion in this retrospective, single-center study. Symptomatic aneurysms and isolated ruptured iliac aneurysms were excluded. The primary outcome was in-hospital mortality, and secondary outcomes were institutionalization rate and long-term mortality. Associations between predictive factors and in-hospital mortality were evaluated using univariate logistic regression. The local ethics committee approved this study. The mean age (±standard deviation) of the 72 included patients was 73 years (±9.0) and 88% were men. Among the 65 open (90%) and 7 endovascular procedures (10%), overall in-hospital mortality was 21%, 1- and 2-year mortalities were both 26%, and the institutionalization rate was 5%. Mean follow-up was 43 months (Kaplan-Meier estimate). Univariate analysis identified age as associated with a 20% per year increased risk of in-hospital mortality (correlation, P
