title: [Actinomyces odontolyticus isolation during prosthetic aortic graft infection with paraprosthetic duodenal fistula].
abstract: BACKGROUND
  Prosthetic vascular graft infection is a rare complication of vascular surgery. We report a case with graft enteric fistula and Actinomyces odontolyticus bacteremia.
  
  
  METHODS
  A 73 year-old man with a prosthetic aortic graft and who had a parodontal disease, has been hospitalised for fever of unknown origin. Blood cultures grew with Escherichia coli and Actinomyces odontolyticus. The imaging studies indicated graft infection. Laparotomy has confirmed the diagnosis and highlighted a polymicrobial infection and a paraprosthetic duodenal fistula. A review of the literature's data concerning prosthetic vascular graft infections is made. The role of Actinomyces odontolyticus in that case is discussed.
  
  
  CONCLUSIONS
  Prosthetic aortic graft infection due to graft enteric fistula is usually a polymicrobial infection and is a late complication of aortic surgery. Imaging is essential for the diagnosis of prosthetic aortic graft infection. It is possible that Actinomyces odontolyticus has contributed to prosthesis infection in this case.
