Bleeding in children caused by gastrointestinal vascular lesions.

Intestinal vascular malformations in infants and children are rare but must be considered in the differential diagnosis of gastrointestinal bleeding. Many vascular malformation syndromes have associated intestinal lesions. Localization of vascular lesions is essential for successful management. A variety of treatment options including laser photoablation, surgical resection, and other nonoperative therapies have been utilized to treat these disorders.
