Aortoenteric fistula after endovascular aortic repair for an abdominal aortic aneurysm is a rare but severe complication. Particularly, a case of inflammatory abdominal aortic aneurysm is extremely rare and there are only 3 reported cases. A 70-year-old man underwent endovascular aortic repair for impending rupture of an inflammatory abdominal aortic aneurysm and was medicated steroids for approximately 2 years. Four years after endovascular aortic repair, he developed endograft infection with an aortoduodenal fistula and a left psoas abscess. He underwent total endograft excision, debridement, in situ reconstruction of the aorta using prosthetic grafts with omental coverage, and digestive tract reconstruction to prevent leakage. Pseudomonas aeruginosa was detected in the infected aortic sac. The patient has not experienced recurrence of infection in the 35 months since his operation.
In situ rifampin-soaked grafts with omental coverage and antibiotic suppression are durable with low reinfection rates in patients with aortic graft enteric erosion or fistula
