Successful Onyx embolization of the DAVF was performed via the distal left occipital artery using an ev3 Apollo detachable tip microcatheter. He underwent surgical obliteration for the residual DAVF 3\u2005days later. Three months later during a routine postoperative clinic visit, the patient produced a plastic bag containing multiple small pieces of Onyx cast and the detached tip of the Apollo microcatheter that had extruded out from his scalp through small spontaneous holes about 5\u2005weeks after the embolization procedure. This spontaneous extrusion of Onyx can be alarming to the patient not expecting it; however, prior knowledge and discussion can lessen the anxiety of both the treating physician and the patient dealing with such a situation.<\/jats:p>","DOI":"10.1136\/neurintsurg-2015-011879.rep","type":"journal-article","created":{"date-parts":[[2016,8,12]],"date-time":"2016-08-12T09:47:27Z","timestamp":1470995247000},"page":"e38-e38","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":10,"title":["Republished: Onyx extrusion through the scalp after embolization of dural arteriovenous fistula"],"prefix":"10.1136","volume":"8","author":[{"given":"Amit","family":"Singla","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University of Florida, Gainesville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyle Michael","family":"Fargen","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Florida, Gainesville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian","family":"Hoh","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Florida, Gainesville, Florida, USA"},{"name":"University of Florida, Gainesville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,7,31]]},"reference":[{"key":"2025092912113704000_8.9.e38.1","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199811000-00081"},{"key":"2025092912113704000_8.9.e38.2","first-page":"401","article-title":"A reexamination of the angiotoxicity of superselective injection of DMSO in the swine rete embolization model","volume":"20","author":"Chaloupka","year":"1999","journal-title":"AJNR Am J Neuroradiol"},{"key":"2025092912113704000_8.9.e38.3","doi-asserted-by":"publisher","DOI":"10.1586\/17434440.3.6.705"},{"key":"2025092912113704000_8.9.e38.4","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-014-2404-9"},{"key":"2025092912113704000_8.9.e38.5","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A1959"}],"container-title":["Journal of NeuroInterventional Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/neurintsurg-2015-011879.rep","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,9,29]],"date-time":"2025-09-29T19:11:41Z","timestamp":1759173101000},"score":1,"resource":{"primary":{"URL":"https:\/\/jnis.bmj.com\/lookup\/doi\/10.1136\/neurintsurg-2015-011879.rep"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,7,31]]},"references-count":5,"journal-issue":{"issue":"9","published-online":{"date-parts":[[2016,8,12]]},"published-print":{"date-parts":[[2016,9]]}},"alternative-id":["10.1136\/neurintsurg-2015-011879.rep"],"URL":"https:\/\/doi.org\/10.1136\/neurintsurg-2015-011879.rep","relation":{},"ISSN":["1759-8478","1759-8486"],"issn-type":[{"value":"1759-8478","type":"print"},{"value":"1759-8486","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,7,31]]}}}
