A Case of Infected Abdominal Aortic Graft with Pancreatic Fistula: Successful Treatment through a Staged Approach with Percutaneous Catheter Drainage and Partial Graft Excision.

A man in his 60s developed a pancreatic pseudocyst postoperatively after an open graft replacement for a ruptured abdominal aortic aneurysm. Endoscopic drainage was performed; however, this led to an aortic graft infection due to macroscopic communication with the perigraft cavity. Percutaneous drainage was performed to manage the pancreatic fistula and graft infection simultaneously. Although the pancreatic pseudocyst diminished, the aortic graft infection persisted. Subsequently, partial aortic graft replacement with greater omental flap coverage was performed. He was discharged with oral antibiotics, with no recurrence of infections at 10 months.
