Due to the rectum\u2019s 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.<\/jats:p>","DOI":"10.3389\/fgstr.2025.1700403","type":"journal-article","created":{"date-parts":[[2026,1,2]],"date-time":"2026-01-02T05:24:01Z","timestamp":1767331441000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Ischemic proctitis caused by a superior rectal arteriovenous fistula: a case report and literature review"],"prefix":"10.3389","volume":"4","author":[{"given":"Jiaqi","family":"Dong","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ming","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fengju","family":"Yuan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ni","family":"Huang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,1,2]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0043-117946","article-title":"A case of rectal stricture related to ischemic proctitis following rupture of an aortic aneurysm","volume":"6","author":"Iida","year":"2018","journal-title":"Endosc Int Open"},{"key":"B2","doi-asserted-by":"publisher","first-page":"e88","DOI":"10.14309\/crj.2017.88","article-title":"Ischemic proctitis presenting as rectal pain and bloody diarrhea with no apparent cause","volume":"4","author":"Fortinsky","year":"2017","journal-title":"ACG Case Rep J"},{"key":"B3","doi-asserted-by":"publisher","first-page":"1","DOI":"10.23880\/ghij-16000178","article-title":"A rare clinical situation","volume":"5","author":"Ischemic proctitis","year":"2020","journal-title":"Gastroenterol Hepatol Int J"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1148\/91.2.302","article-title":"The radiology of ischemic proctitis","volume":"91","author":"Farman","year":"1968","journal-title":"Radiology"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1007\/BF02048118","article-title":"Acute ischemic proctitis: Report of six cases","volume":"35","author":"Nelson","year":"1992","journal-title":"Dis Colon Rectum"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1016\/S1051-0443(99)70110-7","article-title":"Rectum and sigmoid colon necrosis due to cholesterol embolization after aortic stent-graft implantation","volume":"10","author":"Jaeger","year":"1999","journal-title":"J Vasc Intervent Radiol"},{"key":"B7","doi-asserted-by":"publisher","first-page":"610","DOI":"10.14309\/ajg.0000000000002660","article-title":"Idiopathic myointimal hyperplasia of the mesenteric veins: A rare disorder leading to ischemic proctitis","volume":"119","author":"Dillione","year":"2024","journal-title":"Am J Gastroenterol"},{"key":"B8","doi-asserted-by":"publisher","first-page":"5723403","DOI":"10.1155\/2020\/5723403","article-title":"Al-Jaroushi H.
