We report the case of a 21-year-old male patient with superior mesenteric artery aneurysm due to missed arterial injuries, its complications of enteric fistula and results of surgical treatment. The aneurysm was excised, entreric fistula was closed and aorta-mesenteric bypass using saphenous vein graft was performed. The hemorrhage became masked because of the tamponade in the mesentery during penetrating abdominal injury and initial surgery, and the late complication of false aneurysm came on the scene in follow up. Aortomesenteric by-pass by a transmesenteric approach provides successful result in surgical treatment of superior mesenteric artery aneurysm.
