We report an iatrogenic inferior mesenteric artery arteriovenous fistula in a 30\u2010year\u2010old female, presenting with massive hematochezia 1 month after a left hemicolectomy. Angiography demonstrated a high\u2010flow vascular connection between the inferior mesenteric artery and rectal veins, which was treated with n\u2010butyl\u20102\u2010cyanoacrylate mixed with ethiodized oil for arteriovenous connection occlusion followed by coil embolization of the feeding arteries. Follow\u2010up imaging at 8 months showed no recanalization of the fistula, and she remains asymptomatic 4 years later. Iatrogenic inferior mesenteric artery arteriovenous fistulae, though rare, should be considered after colorectal surgery as a possible cause of recurrent lower gastrointestinal hemorrhage, even within weeks of the operation; dilated mesenteric varices and premature venous filling on the arterial phase are key CT findings. Endovascular management targeting the arteriovenous communication and feeding arteries can achieve durable occlusion in these high\u2010flow fistulae.<\/jats:p>","DOI":"10.1155\/crra\/3779245","type":"journal-article","created":{"date-parts":[[2026,7,22]],"date-time":"2026-07-22T09:01:08Z","timestamp":1784710868000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Endovascular Treatment of an Iatrogenic Inferior Mesenteric Arteriovenous Fistula Presenting as Massive Lower Gastrointestinal Hemorrhage: A Case Report"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7530-3968","authenticated-orcid":false,"given":"Maria","family":"Mihailescu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8477-932X","authenticated-orcid":false,"given":"Clayton W.","family":"Commander","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-3263-4515","authenticated-orcid":false,"given":"Robert","family":"Dixon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2082-1004","authenticated-orcid":false,"given":"Nicole A.","family":"Keefe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,22]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.12998\/wjcc.v9.i2.396"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.20524\/aog.2020.0463"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12328-021-01411-9"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/15266028221126941"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0016-5085(84)90422-0"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.4166\/kjg.2013.62.5.296"},{"key":"e_1_2_10_7_2","doi-asserted-by":"publisher","DOI":"10.3389\/fphar.2025.1512806"},{"key":"e_1_2_10_8_2","doi-asserted-by":"publisher","DOI":"10.1155\/2021\/8854806"},{"key":"e_1_2_10_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.radcr.2023.01.069"},{"key":"e_1_2_10_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.diii.2013.09.004"},{"key":"e_1_2_10_11_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.RVI.0000175327.10770.40"},{"key":"e_1_2_10_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvir.2013.05.064"},{"key":"e_1_2_10_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvir.2018.05.016"},{"key":"e_1_2_10_14_2","doi-asserted-by":"publisher","DOI":"10.22575\/interventionalradiology.2021-0028"}],"container-title":["Case Reports in Radiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crra\/3779245","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1155\/crra\/3779245","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crra\/3779245","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,22]],"date-time":"2026-07-22T09:01:09Z","timestamp":1784710869000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/crra\/3779245"}},"subtitle":[],"editor":[{"given":"Shashank","family":"Kaushik","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"editor"}]}],"short-title":[],"issued":{"date-parts":[[2026,1]]},"references-count":14,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026,1]]}},"alternative-id":["10.1155\/crra\/3779245"],"URL":"https:\/\/doi.org\/10.1155\/crra\/3779245","archive":["Portico"],"relation":{},"ISSN":["2090-6862","2090-6870"],"issn-type":[{"value":"2090-6862","type":"print"},{"value":"2090-6870","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1]]},"assertion":[{"value":"2026-03-16","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-06-29","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-22","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"3779245"}}
