Solitary Arteriovenous Malformation of the Small Intestine

16-year-old female patient presented with a 2-month istory of gastrointestinal bleeding and anemia. Upper and ower endoscopy, small bowel enteroclysis, and a Meckel’s echnetium scan were normal. She presented to our instiution with continued gastrointestinal bleeding and a heatocrit of 16%. A repeat Meckel’s technetium scan, olonoscopy, and upper endoscopy with enteroscopy to the id-jejunum were normal. Angiography (A) revealed a vasular lesion in the ileum suggestive of an arteriovenous malormation. Laparotomy (B) confirmed a 2-cm nodular vasular malformation located 4.5 feet proximal to the leocecal valve. A small bowel resection and primary anasamosis were performed. Gross inspection (C) revealed a .5-cm soft, red, raised nodule on the mucosal surface. istology (D) confirmed an arteriovenous malformation. he patient was discharged on postoperative day 4 with a table hematocrit. Arteriovenous malformations (AVM) of the small intesine are rare, and the true incidence is unknown.The terms rteriovenous malformation, angiodysplasia, telangiectasia, nd hemangioma describe distinct entities but have been sed interchangeably to describe the same lesion.The nonniform classification of intestinal vascular lesions in the iterature has led to some of the confusion and inaccurate eporting.
