Type II endoleak incidence and aneurysm enlargement of >5 mm after endovascular aneurysm repair were evaluated. The predictive factors for late type II endoleak identified >6 months after endovascular aneurysm repair and aneurysm enlargement were assessed based on the preoperative patient and anatomical characteristics. <b>Results:</b> Late type II endoleak incidence was higher in the patent inferior mesenteric artery at 42.7% (41/96; 95% confidence interval, 33.3-52.7), compared with 22.5% (16/71; 95% confidence interval, 13.5-34.0) in the occluded inferior mesenteric artery group (p = 0.01).
