title: Jejunal arteriovenous malformation, diagnosed by angiography and treated by embolization and catheter-guided surgery: case report and review of literature.
abstract: A case of chronic gastrointestinal hemorrhage caused by a small jejunal arteriovenous malformation (AVM) is reported. Treatment by endovascular embolization was temporarily successful. Subsequently, the patient underwent laparoscopic resection, guided by intraoperative catheter localization with methylene blue. Histopathology confirmed a true AVM. Eighteen months after treatment, the patient is free of symptoms. Literature of jejunal AVMs is reviewed.
