Aortoenteric and paraprosthetic-enteric fistulas: radiologic findings.

Ten cases of graft-intestinal fistulas occurred in 712 patients who had undergone abdominal aortic reconstructive surgery. Radiographic abnormalities were demonstrated in eight--three by conventional barium gastrointestinal examinations and five by angiography. A high index of suspicion of the condition and an aggressive radiologic workup are recommended.
