We present the case of a dural CCF in which access to the venous side of the fistula was achieved via the neuromeningeal trunk and allowed for curative transarterial intravenous coil\/liquid embolic embolization of the lesion. The utility of a transarterial intravenous approach in the face of venous sinus occlusion is highlighted. The neuromeningeal trunk should not be overlooked as a potential access route for transarterial intravenous CCF embolization in cases where traditional endovascular access is limited; this approach does not carry the same risks that are generally associated with pure transarterial embolization along this pathway.<\/jats:p>","DOI":"10.1177\/1591019915581968","type":"journal-article","created":{"date-parts":[[2015,5,5]],"date-time":"2015-05-05T21:21:52Z","timestamp":1430860912000},"page":"234-239","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Neuromeningeal access for transarterial intravenous carotid-cavernous fistula embolization"],"prefix":"10.1177","volume":"21","author":[{"given":"Ramsey","family":"Ashour","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery and Radiology, Harvard Medical School\/Brigham and Women\u2019s Hospital, Boston, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ram","family":"Chavali","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and Radiology, Harvard Medical School\/Brigham and Women\u2019s Hospital, Boston, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2015,5,5]]},"reference":[{"key":"bibr1-1591019915581968","doi-asserted-by":"crossref","unstructured":"Ashour R, Elhammady M and Aziz-Sultan MA.
