In particular, this entity with reflux drainage directly into the ophthalmic vein is extremely rare. We report a case of ethmoidal dural AVF with direct drainage of the superior ophthalmic vein (SOV) and inferior ophthalmic vein (IOV), successfully treated by endovascular surgery. A 58-year-old man presented with progressive diplopia. Angiography and contrast-enhanced CT showed an ethmoidal dural AVF supplied via the bilateral anterior ethmoidal arteries and venous drainage through the left SOV and IOV. A transarterial approach through the bilateral anterior ethmoidal arteries was used to place the microcatheter close to the fistula site. After intra-arterial embolization with 20% N-butyl cyanoacrylate, the dural AVF was completely occluded. In patients with good vascular access, endovascular transarterial embolization may be an effective and less invasive treatment strategy for ethmoidal dural AVF.<\/jats:p>","DOI":"10.1136\/bcr-2013-011098","type":"journal-article","created":{"date-parts":[[2014,3,25]],"date-time":"2014-03-25T11:18:13Z","timestamp":1395746293000},"page":"bcr2013011098","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Ethmoidal dural arteriovenous fistula with unusual drainage route treated by transarterial embolization"],"prefix":"10.1136","volume":"2014","author":[{"given":"Akihiro","family":"Inoue","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahiko","family":"Tagawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshiaki","family":"Kumon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hideaki","family":"Watanabe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daisuke","family":"Shoda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenji","family":"Sugiu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takanori","family":"Ohnishi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2014,3,25]]},"reference":[{"key":"2025042703020714000_2014.mar25_1.bcr2013011098.1","doi-asserted-by":"publisher","DOI":"10.2176\/nmc.44.516"},{"key":"2025042703020714000_2014.mar25_1.bcr2013011098.2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2003.98.3.0498"},{"key":"2025042703020714000_2014.mar25_1.bcr2013011098.3","first-page":"271","article-title":"A clinical anatomical study on canalis orbito-cranialis","volume":"44","author":"Akasaka","year":"1974","journal-title":"J Tokyo Wom Med Univ"},{"key":"2025042703020714000_2014.mar25_1.bcr2013011098.4","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199910000-00014"},{"key":"2025042703020714000_2014.mar25_1.bcr2013011098.5","doi-asserted-by":"publisher","DOI":"10.3171\/2008.6.17601"},{"key":"2025042703020714000_2014.mar25_1.bcr2013011098.6","doi-asserted-by":"crossref","first-page":"809","DOI":"10.1227\/01.neu.0000175733.89623.e8","article-title":"Bilateral ethmoidal dural arteriovenous fistulae: a previously unreported entity: case report","volume":"57","author":"Deshmukh","year":"2005","journal-title":"Neurosurgery"},{"key":"2025042703020714000_2014.mar25_1.bcr2013011098.7","first-page":"107","article-title":"Intraorbital arteriovenous fistula with thrombosed varix: diagnosis and treatment without catheter angiography in a developing country","volume":"23","author":"Mishra","year":"2013","journal-title":"Surg Neurol Int"},{"key":"2025042703020714000_2014.mar25_1.bcr2013011098.8","doi-asserted-by":"publisher","DOI":"10.1016\/S0090-3019(02)00871-6"},{"key":"2025042703020714000_2014.mar25_1.bcr2013011098.9","doi-asserted-by":"publisher","DOI":"10.1227\/01.NEU.0000290889.62201.7F"},{"key":"2025042703020714000_2014.mar25_1.bcr2013011098.10","first-page":"761","article-title":"Transvenous embolization of a dural arteriovenous fistula of the anterior cranial fossa: preliminary results","volume":"21","author":"Defreyne","year":"2000","journal-title":"AJNR Am J Neuroradiol"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2013-011098","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T10:02:12Z","timestamp":1745748132000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2013-011098"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,3,25]]},"references-count":10,"alternative-id":["10.1136\/bcr-2013-011098"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2013-011098","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2014,3,25]]}}}
