Stepwise age-related outcomes of elective endovascular abdominal aortic aneurysm repair: 11-year institutional review.
OBJECTIVE
Endovascular repair of abdominal aortic aneurysms (EVAR) has largely supplanted open surgery over the past 2 decades. Faced with an aging population, the outcomes of EVAR among various age groups were examined.


METHODS
Retrospective review of elective EVAR cases was performed at a single institution from 1998 to 2009. Patients were separated into 4 age groups for easy comparison. Perioperative data were analyzed using Fisher's exact test.


RESULTS
Demographics were similar among the groups except for sex, BMI, and smoking status. The 30-day morbidity and mortality data were not statistically different among groups. From EVAR to end of the study, there was a 10.9% all-cause mortality rate (with no difference among groups) and an 8.0% reintervention rate (with the oldest age group having a lower reintervention rate; P < .03).


CONCLUSIONS
EVAR remains a good treatment option for elective aneurysm repair despite advanced age, which alone does not appear to be an independent predictor of outcome.
