However, new advances in endovascular technology have made the endovascular treatment (EVT) of ethmoidal DAVFs feasible. The aim of this study was to report the clinical and angiographic outcomes of patients harboring DAVFs of the anterior cranial fossa who had undergone EVT as a first-line approach.<\/jats:p>\n<\/jats:sec>\n\nMETHODS<\/jats:title>\nThis was a retrospective study of a consecutive series of patients harboring anterior cranial base DAVFs who had undergone EVT as a first-line approach at four institutions. Angiographic follow-up was performed at 6 months. Immediate and late serious clinical events were assessed during follow-up, including death and stroke. Special emphasis was given to visual status before and after the treatment.<\/jats:p>\n<\/jats:sec>\n\nRESULTS<\/jats:title>\nBetween 2008 and 2020, 37 patients with ethmoidal DAVFs were admitted to the participating centers. In 2 patients, EVT was not attempted; therefore, 35 patients underwent EVT as a first-line procedure. An isolated transarterial approach was performed in 19 (54.3%) patients. The transvenous approach was performed exclusively in 12 (34.3%) patients, and combined access was used in 4 (11.4%) patients. The most frequently used arterial access route was the ophthalmic artery in 82.6% of the patients. Immediately, complete angiographic occlusion was achieved in 31 (91.2%) of 34 patients whose treatment was accomplished. Six-month control angiography revealed that 30 (88.2%) DAVFs were totally occluded. Complications occurred in 3 (8.8%) patients, including 1 (2.9%) patient who had central retinal artery occlusion. No significant difference in complications or occlusion rates was noted between the transarterial and transvenous approaches.<\/jats:p>\n<\/jats:sec>\n\nCONCLUSIONS<\/jats:title>\nMost anterior cranial base DAVFs can be successfully treated via an endovascular approach. Neurological and visual complications are rare, even if the ophthalmic artery is used as the primary access route. Efforts should be focused on prospectively comparing the results of EVT and surgical management.<\/jats:p>\n<\/jats:sec>","DOI":"10.3171\/2022.2.jns212588","type":"journal-article","created":{"date-parts":[[2022,4,26]],"date-time":"2022-04-26T17:55:59Z","timestamp":1650995759000},"page":"1758-1765","source":"Crossref","is-referenced-by-count":17,"title":["Endovascular treatment of anterior cranial base dural arteriovenous fistulas as a first-line approach: a multicenter study"],"prefix":"10.3171","volume":"137","author":[{"given":"Felipe P.","family":"Trivelato","sequence":"first","affiliation":[{"name":"Division of Interventional Neuroradiology, Fel\u00edcio Rocho Hospital, Belo Horizonte, Minas Gerais, Brazil;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stanislas","family":"Smajda","sequence":"additional","affiliation":[{"name":"Interventional Neuroradiology Department, Fondation Rothschild, Paris, France;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suzana","family":"Saleme","sequence":"additional","affiliation":[{"name":"Department of Radiology, Centre Hospitalier et Universitaire Dupuytren, Limoges, France;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu\u00eds Henrique de","family":"Castro-Afonso","sequence":"additional","affiliation":[{"name":"Division of Interventional Neuroradiology, Hospital das Cl\u00ednicas, Medical School, University of S\u00e3o Paulo, Ribeir\u00e3o Preto, S\u00e3o Paulo, Brazil; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thiago G.","family":"Abud","sequence":"additional","affiliation":[{"name":"Division of Interventional Neuroradiology, Hospital das Cl\u00ednicas, Medical School, University of S\u00e3o Paulo, Ribeir\u00e3o Preto, S\u00e3o Paulo, Brazil; and"},{"name":"Division of Interventional Neuroradiology, Hospital Israelita Albert Einstein, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandre C.","family":"Ulh\u00f4a","sequence":"additional","affiliation":[{"name":"Division of Interventional Neuroradiology, Fel\u00edcio Rocho Hospital, Belo Horizonte, Minas Gerais, Brazil;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raphael","family":"Blanc","sequence":"additional","affiliation":[{"name":"Interventional Neuroradiology Department, Fondation Rothschild, Paris, France;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel G.","family":"Abud","sequence":"additional","affiliation":[{"name":"Division of Interventional Neuroradiology, Hospital das Cl\u00ednicas, Medical School, University of S\u00e3o Paulo, Ribeir\u00e3o Preto, S\u00e3o Paulo, Brazil; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charbel","family":"Mounayer","sequence":"additional","affiliation":[{"name":"Department of Radiology, Centre Hospitalier et Universitaire Dupuytren, Limoges, France;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michel","family":"Piotin","sequence":"additional","affiliation":[{"name":"Interventional Neuroradiology Department, Fondation Rothschild, Paris, France;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco T\u00falio S.","family":"Rezende","sequence":"additional","affiliation":[{"name":"Division of Interventional Neuroradiology, Fel\u00edcio Rocho Hospital, Belo Horizonte, Minas Gerais, Brazil;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"1","key":"b1","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"79","DOI":"10.3171\/2008.6.17601","article-title":"Management strategies for anterior cranial fossa (ethmoidal) dural arteriovenous fistulas with an emphasis on endovascular treatment","volume":"110","author":"Agid R","year":"2009","unstructured":"Agid R, Terbrugge K, Rodesch G, Andersson T, S\u00f6derman M.
