Arteriovenous malformations of the intestine in children. Study of 8 cases and review of the literature

Abstract Eight children with arteriovenous malformations of the gastrointestinal tract were studied during a two year period (1989-1993). The main localization of the arteriovenous malformations were: ascending colon (five cases), descending colon (five cases), terminal ileum (three cases), rectum and sigmoid (three cases). Diagnosis approach was made with colonoscopy and arteriography. Surgical resection of the affected segments was the therapeutical procedure in seven of the eight cases.
