Abstract

Objectives: Advanced age is a significant risk factor that has traditionally steered patients away from open aneurysm repair and toward expectant management. Today, however, the reduced morbidity and mortality of aortic stent grafting has created a new opportunity for aneurysm repair in patients previously considered too high a risk for open surgery. Here we report our experience with endovascular aneurysm repair (EVAR) in nonagenarians. Methods: Retrospective chart review identified all patients >90-years-old undergoing EVAR over a 9-year period at our institution. Collected data included preoperative comorbidities, perioperative complications, endoleaks, reinterventions, and long-term survival. Results: 24 patients underwent EVAR. The mean age was 91.5 years (range 90-94) among 15 (63%) males and 9 (37%) females. Mean abdominal aortic aneurysm diameter was 6.3 ± 1.1 cm. Eight patients (33%) were symptomatic (pain or tenderness). There were no ruptures. Fourteen patients (58%) had general anesthesia while 10 (42%) had local or regional anesthesia. Mean postoperative length of stay was 3.2 ± 2.4 days (2.8 ± 1.9 days for asymptomatic vs 4.1 ± 3.2 days for symptomatic, P = .29). There was one perioperative mortality (4.2%). There were two local groin seromas (8.3%) and six systemic complications (25%). One patient required reintervention for endoleak (4.2%). There were no aneurysm related deaths beyond the 30-day postoperative period. Mean survival beyond 30 days was 29.7 ± 18.0 months for patients expiring during follow-up. Cumulative estimated 12, 24, and 36-month survival rates were 83%, 64%, and 50%, respectively. Linear regression analysis demonstrated an inverse relationship between the number of preoperative comorbidities and postoperative survival in our cohort (R2 = 0.701), with significantly decreased survival noted for patients presenting with >5 comorbidities. Those still alive in follow-up have a mean survival of 36.1 ± 16.0 months. Conclusion: This is the largest reported EVAR series in nonagenarians. Despite their advanced age, these patients benefit from EVAR with low morbidity, low mortality, and mean survival exceeding 2.4 years. Survival appears best in those patients with <5 comorbidities. With or without symptoms, patients over the age of 90 should be considered for EVAR.
