title: Arteriography in malignant neoplasms of the bowel.
abstract: Eighty patients with gastrointestinal bleeding were investigated by angiography over a four-year period. Nine had malignant neoplasms of the bowel. Inconspicuous neovascularity was the most constant finding, best seen in leiomyosarcoma of the small bowel and adenocarcinoma of the colon. Neovascularity was not seen in a patient with reticulum cell sarcoma of colon detected by extravasation. When other studies including endoscopy and barium examinations have failed to explain acute or chronic bleeding, an appreciable number of intestinal neoplasms may be demonstrated by arteriography.
