Ruptured Abdominal Aortic Aneurysm: Endovascular Repair Does Not Confer Any Long-term Survival Advantage Over Open Repair

Abstract

Recent studies have suggested that endovascular aneurysm repair (EVAR) may reduce the perioperative mortality of ruptured abdominal aortic aneurysm (AAA). Whether EVAR confers any long-term survival advantage over published results for open repair of ruptured AAA has not been established. We conducted a single-center retrospective study over a 10-year period (1994–2004) examining the long-term outcome of patients who have undergone endovascular repair of ruptured AAA. Fifty-four patients underwent endovascular repair of a ruptured AAA. The median age was 75 years (interquartile range 69.5–79.5 years); 42 (78%) patients were male. The perioperative mortality rate was 37%. During a median follow-up of 32 months (range 14–48 months), there were 5 aneurysm-related and 13 non-aneurysm-related deaths. Overall, the 3- and 5-year survival rates were 36% and 26%, respectively. EVAR does not appear to confer any overall survival advantage in the mid- to long term compared with the published results for open repair. The reasons for this remain unclear. Further, larger studies are required to confirm these results.
