Abstract

A 15-year-old boy developed massive intestinal bleeding. The initial mesenteric angiography and ileocolectomy failed to reveal the bleeding site. A repeat mesenteric angiography performed when bleeding recurred showed active bleeding from an ileal branch of the mesenteric artery. Histologically, the lesion proved to be a caliber-persistent submucosal artery that had ruptured. This appears to be the first report of “caliber-persistent” artery in the ileum.
