Abdominal aortic aneurysm repair in octogenarians: Outcomes and predictors

Objectives. This study was undertaken to evaluate predictors and outcomes of octogenarians who underwent abdominal aortic aneurysm repair. Design. A prospective observational study. Materials and methods. Between 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. Results. The 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 zoos 84 +/- 7% and 48 +/- 21%. Only coronary artery disease was a significant predictor Of survival using multivariate stepwise logistic regression analysis. Conclusions. In this series, AAA surgery was carried out in selected octogenarians without affecting long-term survival.
