Aortoduodenal Fistula Occurring One Month after Operation for an Inflammatory Abdominal Aortic Aneurysm / 日本心臓血管外科学会雑誌

ABSTRACT

A 61-year-old woman was admitted with abdominal and low back pain. The patient underwent graft replacement for inflammatory abdominal aortic aneurysm. One month postoperatively, the patient fell into hypovolemic shock with massive melena and hematemesis. Laparotomy and duodenotomy revealed a fistula between the third portion of the duodenum and the distal anastomosis of the vascular prosthesis. The fistula of the aorta was repaired with omentopexy, gastrojejunostomy and Braun's anastomosis. One month later, aortoduodenal fistula recurred. The vascular prosthesis was partially removed and the aorta was closed at the infrarenal level. After the closure of the posterior duodenal defect, a left axillo-femoral bypass was constructed. She fully recovered and discharged.
