Vascular Malformations of the Intestine An Important Cause of Obscure Gastrointestinal Hemorrhage*
Abstract
AbstractCase reports of five patients are presented who had obscure massive bleeding from various vascular malformations of the gastrointestinal tract. The small size and vascular nature of these lesions make the diagnosis by routine roentgenographic studies difficult or impossible. They are equally difficult to find even during exploratory laparotomy. Selective mesenteric angiography is probably the best diagnostic aid and may be carried out even if the patient is not actually bleeding at the time. Arteriovenous malformations are more frequent in the right colon. When such a lesion is suspected and all radiographic studies are negative, blind right colectomy is more apt to cure the patient than any other procedure.This content is limited to qualifying members.
