BACKGROUND: The role of symptomatic presentation in directing reintervention after endovascular aortic aneurysm repair (EVAR) was investigated. METHODS: All patients undergoing infrarenal EVAR between 2001 and 2009 were studied. Those needing reintervention were divided into symptomatic and asymptomatic presentations. Kaplan-Meier survival curves were used to calculate freedom from reintervention, and log rank tests for subgroup analyses. Multivariable analysis identified risk factors for reintervention. RESULTS: The study included 553 patients with a mean(s.d.) age of 75(7) years and aneurysm diameter of 65(13) mm. The 30-day mortality rate was 2.5 per cent. Median follow-up was 31 (range 1-97) months. There were 86 reinterventions in 69 (12.5 per cent) of 553 patients; 41 presented with symptoms and 28 were asymptomatic. Reintervention-free survival rates at 1, 3 and 5 years were 90.1, 85.3 and 81.2 per cent. The reintervention rate was higher in patients who needed an intraoperative adjunct during the index procedure (P = 0.014) and in those who did not have intraoperative computed tomography angiography (P = 0.024). Intraoperative adjuncts were an independent risk factor for future reintervention (hazard ratio 2.62, 95 per cent confidence interval 1.18 to 3.76; P = 0.012). CONCLUSION: Most patients requiring reintervention presented symptomatically. A high-risk subgroup may be identifiable to rationalize a postoperative surveillance programme.
