underwent in situ aortic reconstructions (48% abdominal aortic, 52% aortoiliac) using CAAs for infective aortic aneurysm (n 1⁄4 25 [66%]) and aortic prosthesis infection (n 1⁄4 13 [34%]). Among them, four (10.5%) patients presented with aortoenteric fistula. There were four (10.5%) early (<30 days) and seven (18%) late postoperative deaths during the follow-up period (median, 13.6 months; range, 1-72 months). Early mortality was attributed to CAA rupture, whereas late mortality was not related to an aorta-related cause. Four (10.5%) GRCs developed during the follow-up period; these included thrombotic iliac limb occlusion (n 1⁄4 1), aneurysmal dilation of CAA (n1⁄4 1), aortoenteric fistula (n 1⁄4 1) after fall down injury, and graft rupture (n 1⁄4 1). Patient survival and event-free survival rates at 3 years were 77% and 64%, respectively. Conclusions: In situ abdominal aortic reconstruction with CAA showed good results for patients with primary or secondary aortic infection even in immunocompromised patients. Although aorta-related mortality usually developed in the early postoperative period, postoperative surveillance of CAA is recommended to detect GRCs.
