In situ Replacement of Mycotic Thoracoabdominal Aortic Aneurysm Using Expanded-polytetrafluoroethylene Graft With Omental Flap

AbstractA mycotic aneurysm of the thoracoabdominal aorta was detected in a 68-year-old male after 1 month of antibiotic therapy for acute enteritis. The infected aorta was resected and revascularized via in situ grafting using an expanded-polytetrafluoroethylene graft with reconstruction of the visceral arteries. The implanted graft was covered with an omental flap. The patient was discharged 39 days after the operation. This procedure may help prevent postoperative graft infection and improve the surgical outcome in mycotic aneurysms
