Workup with magnetic resonance angiography showed early opacification of the left sigmoid sinus and internal jugular vein as well as asymmetric and abundant opacification of the left external carotid artery branches, suspicious for a dural arteriovenous fistula (dAVF). Diagnosis was confirmed with cerebral angiography, consistent with a left-sided Cognard type I dAVF.\n                    <jats:sup>1<\/jats:sup>\n                    Initial treatment attempt was made with transarterial 6% ethylene-vinyl alcohol copolymer (Onyx 18) embolization of feeders from the occipital and middle meningeal arteries. However, embolization was not curative and there was a recurrence of a highly bothersome tinnitus 3 wk following treatment. Angiography redemonstrated the transverse sinus dAVF with new recruitment arising from several feeders, including the left external carotid artery, middle meningeal artery, and superficial temporal artery, now Cognard type IIa. Definitive treatment through a transvenous coil embolization provided permanent obliteration of the fistula without recrudescence of symptoms on follow-up. In this video, the authors discuss the nuances of treating a dAVF via a transvenous embolization. Patient consent was given prior to the procedure, and consent and approval for this operative video were waived because of the retrospective nature of this manuscript and the anonymized video material.\n                  <\/jats:p>","DOI":"10.1093\/ons\/opaa454","type":"journal-article","created":{"date-parts":[[2021,1,31]],"date-time":"2021-01-31T01:46:30Z","timestamp":1612057590000},"page":"E290-E291","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Transvenous Coil Embolization of a Transverse-Sigmoid Sinus Dural Arteriovenous Fistula: 2-Dimensional Operative Video"],"prefix":"10.1227","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2283-3612","authenticated-orcid":false,"given":"Santiago","family":"Gomez-Paz","sequence":"first","affiliation":[{"name":"Neurosurgery Service, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yosuke","family":"Akamatsu","sequence":"additional","affiliation":[{"name":"Neurosurgery Service, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed M","family":"Salem","sequence":"additional","affiliation":[{"name":"Neurosurgery Service, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin M","family":"Moore","sequence":"additional","affiliation":[{"name":"Neurosurgery Service, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ajith J","family":"Thomas","sequence":"additional","affiliation":[{"name":"Neurosurgery Service, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher S","family":"Ogilvy","sequence":"additional","affiliation":[{"name":"Neurosurgery Service, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2021,4]]},"reference":[{"issue":"3","key":"bib1-20251027","doi-asserted-by":"crossref","first-page":"671","DOI":"10.1148\/radiology.194.3.7862961","article-title":"Cerebral dural arteriovenous fistulas: clinical and angiographic correlation with a revised classification of venous drainage","volume":"194","author":"Cognard","year":"1995","journal-title":"Radiology"}],"container-title":["Operative Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/ons\/article-pdf\/20\/4\/E290\/36587256\/opaa454.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/www.ovid.com\/10.1093\/ons\/opaa454","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T17:02:31Z","timestamp":1786122151000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.1093\/ons\/opaa454"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,1,30]]},"references-count":1,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2021]]}},"URL":"https:\/\/doi.org\/10.1093\/ons\/opaa454","relation":{},"ISSN":["2332-4252","2332-4260"],"issn-type":[{"value":"2332-4252","type":"print"},{"value":"2332-4260","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,1,30]]},"assertion":[{"value":"2020-09-11","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2020-11-11","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
