[Angiodysplasia of the colon. Apropos of 2 cases]

Angiodysplasia of the colon is a vascular lesion which involves the arterioles, venules and small venous vessels; usually it is a lesion of the aged and presents with rectorrhagia, melena or chronic anemia due to chronic blood loss. We present two cases of angiodysplasia of the colon in two female patients in the eighth decade of their lives, treated in the Servicio de Cirugía del Hospital Universitario Virgen Macarena de Sevilla. We emphasize the value of the angiographic study for the diagnosis of this lesion, and also the usefulness of isotopic study with labeled erythrocytes for the localization. The treatment of choice is surgical resection of the affected area. It was performed in both patients. One of them died.
