Abstract

Selective mesenteric angiography has become the method of choice for localization of a gastrointestinal tract bleeding source when standard techniques have failed. Hemorrhage originating from the small intestine presents a unique and technically challenging problem, as it generally cannot be seen or ablated by conventional endoscopy. Hemorrhagic small bowel lesions are treated in several ways, including angiography with catheter-directed embolization and enteroscopy during laparotomy for bowel resection. This case report describes the appearance and treatment of a bleeding jejunal arteriovenous malformation, which is an unusual cause of lower gastrointestinal tract blood loss. This rare lesion was localized and resected after superselective catheterization of the bleeding artery with subsequent intraoperative methylene blue injection. This procedure enabled prompt surgical removal of the lesion and avoided the complications of small bowel ischemia or infarction after catheter-directed embolization.
