Video 1 demonstrates this technique employed in a typical case using Onyx (Medtronic, Minnesota, USA) to embolize a cerebrospinal fluid-venous fistula at the left L1 neural foramen.<\/jats:p><jats:p><jats:fig position=\"float\" id=\"V1\" orientation=\"portrait\"><jats:label>Video 1<\/jats:label><jats:caption><jats:title>Technical video demonstrating dual-microcatheter and coil\/balloon pressure cooker technique.<\/jats:title><\/jats:caption><jats:media xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:role=\"media-player-id\" xlink:href=\"BMJ Journals Video Player\" id=\"media1\" mimetype=\"application\" mime-subtype=\"mp4\" content-type=\"play-in-place height-270 width-480\" position=\"float\" orientation=\"portrait\"\/><\/jats:fig><\/jats:p>","DOI":"10.1136\/neurintsurg-2022-019005","type":"journal-article","created":{"date-parts":[[2022,6,15]],"date-time":"2022-06-15T17:20:30Z","timestamp":1655313630000},"page":"614-614","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":11,"title":["Dual microcatheter and coil\/balloon pressure cooker technique for transvenous embolization of cerebrospinal fluid-venous fistulas"],"prefix":"10.1136","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8669-9454","authenticated-orcid":false,"given":"Donna","family":"Parizadeh","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio H C","family":"Vasconcelos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David A","family":"Miller","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olga P","family":"Fermo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thien J","family":"Huynh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2022,6,15]]},"reference":[{"key":"2024052309535267000_15.6.614.1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0000000000000639"},{"key":"2024052309535267000_15.6.614.2","doi-asserted-by":"crossref","DOI":"10.1136\/neurintsurg-2021-018466","article-title":"Clinical and imaging outcomes of cerebrospinal fluid-venous fistula embolization","author":"Brinjikji","year":"2022","journal-title":"J Neurointerv Surg"},{"key":"2024052309535267000_15.6.614.3","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A7014"},{"key":"2024052309535267000_15.6.614.4","article-title":"Transvenous embolization of a cerebrospinal fluid\u2013venous fistula for the treatment of spontaneous intracranial hypotension","author":"Borg","year":"2021","journal-title":"J Neurointerv Surg"},{"key":"2024052309535267000_15.6.614.5","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A7409"},{"key":"2024052309535267000_15.6.614.6","doi-asserted-by":"publisher","DOI":"10.1136\/neurintsurg-2020-016566"}],"container-title":["Journal of NeuroInterventional Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/neurintsurg-2022-019005","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,23]],"date-time":"2024-05-23T16:54:04Z","timestamp":1716483244000},"score":1,"resource":{"primary":{"URL":"https:\/\/jnis.bmj.com\/lookup\/doi\/10.1136\/neurintsurg-2022-019005"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,6,15]]},"references-count":6,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2023,5,16]]},"published-print":{"date-parts":[[2023,6]]}},"alternative-id":["10.1136\/neurintsurg-2022-019005"],"URL":"https:\/\/doi.org\/10.1136\/neurintsurg-2022-019005","relation":{},"ISSN":["1759-8478","1759-8486"],"issn-type":[{"value":"1759-8478","type":"print"},{"value":"1759-8486","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,6,15]]}}}
