A rare cause of small bowel bleeding

Abstract

We present a rare cause of gastrointestinal bleeding resulting from fistulae between the mesenteric artery and portal venous system, caused as a late complication of sleeve gastrectomy. A high index of suspicion, based upon venous engorgement without an occluding thrombus, enabled prompt diagnosis and occlusion of the fistulae with coils, leading to marked clinical improvement.
