It is extremely rare for chronic ischemia of the mesenteric artery to cause constrictive ischemic colitis in the right colon. A 71-year-old man began to complain of a mild sense of bloating and constipation, and was referred to our hospital for further evaluation. A barium enema examination revealed a constriction of the ascending colon. Colonoscopy showed the constricted area had erosion, which blocked the passage of the colonoscope. A biopsy led to categorization as Group 1. Abdominal angiography predicted that blood flow to the right colon from the inferior mesenteric artery via the left colic artery, the marginal artery and the middle colic artery would be found. The obstruction had persisted for approximately 3 months, and so a right hemicolectomy was performed. A 6-cm-long circumferential stricture was observed in the ascending colon, and ischemic changes with ulcerative lesions that showed inflammatory exudate and granulation were histologically identified. No particular complications were found either during or after the surgery.
