Abdominal Aortic Aneurysm Repair in Octogenarians: Outcomes and Predictors

ObjectivesThis study was undertaken to evaluate predictors and outcomes of octogenarians who underwent abdominal aortic aneurysm repair.DesignA prospective observational study.Materials and methodsBetween January 1st, 1997 and April 15th, 2005, 31 octogenarians were admitted to our Department with the diagnosis of abdominal aortic aneurysm. Mean follow-up time was 53.7±27.2 months. All patients were in good clinical condition and represented a selected healthy group of octogenarians.ResultsThe overall perioperative (30-days) mortality rate was 3.1%. The total in-hospital morbidity rate was 22.6%. Overall survival estimates at 48 and 96 months were 81±8% and 46±21%, respectively. The actuarial freedom from aneurysm-related death at 48 and 96 months was 96±4% and 96±4%, respectively. The actuarial freedom from aneurysm-unrelated death at 48 and 96 months was 84±7% and 48±21%. Only coronary artery disease was a significant predictor of survival using multivariate stepwise logistic regression analysis.ConclusionsIn this series, AAA surgery was carried out in selected octogenarians without affecting long-term survival.
