Salmonella organisms have been responsible for half of the reported cases of infected aortic aneurysms, although other bacteria have been incriminated. This is the second reported case in which Campylobacter fetus subspecies fetus apparently infected an inflammatory aortic aneurysm. In this 70-year-old man the organism was isolated and treated prior to resection of the aneurysm and inline grafting. Specific antibiotic therapy was continued for 8 weeks postoperatively. Examination and CT scans obtained after 9 months of follow-up reveal no evidence of recurrent infection.
