N2 - BACKGROUND: In the endovascular era, elderly patients are offered repair of their aortoiliac aneurysms (AAA) more frequently than in the past. Our objective is to compare age groups and draw inferences for AAA repair outcomes.STUDY DESIGN: We identified 20,095 patients who underwent AAA repair between 2005 and 2010 using the American College of Surgeons NSQIP national database. Preoperative characteristics and outcomes were compared among age groups (group A: 0 to 64 years; B: 65 to 79 years; C: 80 to 89 years; and D: 90 years and older).RESULTS: The age distribution of the cohort was A: 17.1%, B: 57.2%, C: 24%, and D: 1.7%. Nonagenarians presented significantly more often as emergencies in comparison with groups A to C (A: 13.8%, B: 10.8%, C: 12.9%, D: 22.1%; p < 0.001). Endovascular aneurysm repair was performed more frequently in older patients (A: 55.2%, B: 63.7%, C: 74.6%, D: 77.9%; p < 0.001). Risk of any complication was significantly different among groups, becoming more prevalent with advanced age (A: 22.8%, B: 23.4%, C: 24.7%, D: 27.8%; p = 0.041). Nonsurgical complications (A: 14.7%, B: 16.4%, C: 18%, D: 19.8%; p < 0.001) and cardiovascular complications (A: 3.9%, B: 4.5%, C: 5.5%, D: 5.2%; p = 0.003) were also higher with advanced age. Overall mortality was 3.1%, 4.9%,7.2%, and 13.2% for groups A to D, respectively (p < 0.001). Mortality after elective AAA repair was significantly higher for open surgery compared with endovascular aneurysm repair in all age groups (open surgery vs endovascular aneurysm repair, A:1.9% vs 0.5%; p = 0.001; B: 3.9% vs 1.2%; p < 0.001; C: 7.4% vs 2%; p < 0.001; D: 18.8% vs 3.8%; p = 0.004). After adjusting for confounders in the entire cohort, advanced age persisted as an independent factor for postoperative mortality with a higher risk of death of 1.8 (95% CI, 1.3-2.5), 2.7 (95% CI, 1.9-3.8), and 3.3 (95% CI, 1.8-6.1) times for groups B, C, and D, respectively (group A reference).CONCLUSIONS: Advanced age is independently associated with higher risk of death after AAA repair and indication for surgery should be adjusted for different age groups accordingly. Endovascular aneurysm repair should be preferred for octogenarians and nonagenarians with indication to undergo repair of their AAA.
