Ischemic proctitis is a rare but severe condition characterized by ischemic injury to the rectum due to insufficient blood supply from the vessels feeding the rectum. Due to the rectum's rich collateral circulation, ischemic proctitis is uncommon. We present a case of a 61-year-old man with ischemic proctitis presenting primarily with rectal bleeding. Angiography confirmed the presence of a superior rectal arteriovenous fistula. The diagnostic process was quite challenging.The patient underwent endoscopic hemostasis and interventional embolization, and eventually underwent proctectomy due to rectal stenosis.A literature review on ischemic proctitis is also included.
