A 61-year-old man visited our hospital for melena. Colonoscopy revealed colonic diverticulosis and massive bleeding in the ascending colon, but the location of bleeding diverticula was not determined. Mesenteric angiography was then carried out. A superior mesenteric arteriogram failed to demonstrate the bleeding site, but selective right colic arteriogram showed extravasation of contrast medium in the ascending colon. The patient was successfully treated with subsequent transcatheter arterial embolization. In the present case, initial colonoscopy was useful in evaluating bleeding site, which enabled successful selective angiography and arterial embolization.
