Abstract
A 77-year-old man who underwent graft replacement of abdominal aorta presented with disorientation on postoperative day 20. Laboratory data showed high CRP (16.8 mg/dl). Computed tomography proved fluid retention and air around the prosthetic graft. We diagnosed abdominal aortic graft infection and performed resection of the whole infected graft, in-situ graft replacement of abdominal aorta, and omental wrapping. Antibiotics was rubbed around the graft and fixed by fibrin glue. Bacteroides fragilis was identified in preoperative blood culture and intraoperative fluid culture. The postoperative course was well and no reinfection had been occured for last 7 months. In the case of abdominal aortic graft infection, we never forget the possibility of anaerobic bacterialinfection and should adopt the suitable method of microbial culture and select optimal antibiotics.
