ABSTRACT
A 70-year-old man with abdominal aortic aneurysm repair presented with fever accompanied by rigors and abdominal pain one month after the procedure. Radiological investigations showed a perigraft collection. The collection was drained and the abscess cavity was lavaged. Cultures of pus and blood both yielded Group D Salmonella (non-typhi), which was treated with ceftriaxone and ciprofloxacin. The patient was followed-up for the past eight months without any further symptoms. Perigraft infections post abdominal aortic aneurysm repair could be caused by enteric organisms and must be treated with long-term appropriate antibiotics, depending on the microbiological finding, besides surgical drainage and lavage.
