Transvenous Onyx embolization is rarely performed, and usually in cases of carotid cavernous fistulas. We describe a novel technique of transvenous Onyx embolization in the treatment of three high risk DAVFs and one vein of Galen (VOG) AVM.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Cases were evaluated with specific attention to technical caveats, clinical indications, and complications. Patients were treated during 2011\u20132012 by two operators (FCA and CGM). Standard transfemoral venous approaches were employed in order to obtain access into the draining venous system in all cases.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Four female patients, aged 5\u2005months to 68\u2005years, were treated. Two patients, one presenting with headache and the other with a bruit, demonstrated high risk DAVFs involving the transverse\u2013sigmoid sinuses. One patient, who was asymptomatic, manifested a high risk ethmoidal DAVF that was discovered incidentally during treatment of a basilar aneurysm. The final patient presented with symptoms of a pineal region mass and was found to have a VOG AVM. In all cases, a microcatheter was navigated through the draining venous pouch and into the ostium of an arterial feeder. A single Onyx infusion from this position filled multiple arterial feeders and resulted in cures in the first three patients and a significant reduction in AVM nidus in the fourth patient. No complications occurred.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Transvenous Onyx infusion into a single arterial feeder can produce retrograde embolization of numerous other arterial feeders supplying high risk DAVFs and complex cerebral AVMs. This technique appears to be safe and potentially curative in select cases.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/neurintsurg-2012-010628","type":"journal-article","created":{"date-parts":[[2013,3,6]],"date-time":"2013-03-06T21:39:51Z","timestamp":1362605991000},"page":"281-285","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":41,"title":["Transvenous to arterial Onyx embolization"],"prefix":"10.1136","volume":"6","author":[{"given":"Felipe C","family":"Albuquerque","sequence":"first","affiliation":[{"name":"Division of Neurological Surgery, Barrow Neurological Institute, St Joseph's Hospital and Medical Center, Phoenix, Arizona, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew F","family":"Ducruet","sequence":"additional","affiliation":[{"name":"Division of Neurological Surgery, Barrow Neurological Institute, St Joseph's Hospital and Medical Center, Phoenix, Arizona, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R Webster","family":"Crowley","sequence":"additional","affiliation":[{"name":"Division of Neurological Surgery, Barrow Neurological Institute, St Joseph's Hospital and Medical Center, Phoenix, Arizona, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruth E","family":"Bristol","sequence":"additional","affiliation":[{"name":"Division of Neurological Surgery, Barrow Neurological Institute, St Joseph's Hospital and Medical Center, Phoenix, Arizona, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Azam","family":"Ahmed","sequence":"additional","affiliation":[{"name":"Division of Neurological Surgery, Barrow Neurological Institute, St Joseph's Hospital and Medical Center, Phoenix, Arizona, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cameron G","family":"McDougall","sequence":"additional","affiliation":[{"name":"Division of Neurological Surgery, Barrow Neurological Institute, St Joseph's Hospital and Medical Center, Phoenix, Arizona, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2013,3,6]]},"reference":[{"key":"2025092912260582000_6.4.281.1","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199706000-00004"},{"key":"2025092912260582000_6.4.281.2","doi-asserted-by":"crossref","first-page":"345","DOI":"10.1007\/s00234-012-1107-8","article-title":"Transvenous balloon-assisted transarterial Onyx embolization of transverse-sigmoid dural arteriovenous malformation","volume":"55","author":"Jittapiromsak","year":"2012","journal-title":"Neuroradiology"},{"key":"2025092912260582000_6.4.281.3","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A2702"},{"key":"2025092912260582000_6.4.281.4","doi-asserted-by":"crossref","first-page":"191","DOI":"10.3340\/jkns.2011.50.3.191","article-title":"Vein of Galen aneurysmal malformation: endovascular management of 6 cases in a single institute","volume":"50","author":"Moon","year":"2011","journal-title":"J Korean Neurosurg Soc"},{"key":"2025092912260582000_6.4.281.5","doi-asserted-by":"publisher","DOI":"10.1227\/NEU.0b013e318212bb34"},{"key":"2025092912260582000_6.4.281.6","doi-asserted-by":"publisher","DOI":"10.4103\/0028-3886.76877"},{"key":"2025092912260582000_6.4.281.7","doi-asserted-by":"publisher","DOI":"10.1016\/j.wneu.2010.01.009"},{"key":"2025092912260582000_6.4.281.8","doi-asserted-by":"crossref","first-page":"179","DOI":"10.1177\/159101990901500207","article-title":"Embolization of a cavernous sinus dural arteriovenous fistula with Onyx via direct puncture of the cavernous sinus through the superior orbital fissure: asystole resulting from the trigeminocardiac reflex.
