A bleeding Meckel's diverticulum diagnosed by arteriography.

A case of Meckel's bleeding diverticulum diagnosed by emergent arteriography is presented. Arteriography revealed an extravasation of contrast medium into the distal ileum and an abnormal ileal artery which passed to the antimesenteric border of the ileum. The diverticulum was demonstrated by double contrast study of the small intestine. The merits of emergent arteriography and other examinations for diagnosing Meckel's diverticulum are discussed.
