A 64-yr-old man presented with leg spasms and progressively worsening gait. Angiography demonstrated a lateral medullary AVM. Patient consent was obtained for the surgical treatment of this lesion. Owing to its eloquent location, an occlusion in situ was performed without resection.\n                    <jats:sup>1,2<\/jats:sup>\n                    This technique relies on the interruption of the arterial blood supply and occlusion of the draining vein to occlude the AVM. Intraoperative neurophysiological monitoring of motor and somatosensory evoked potentials was used, and the elimination of arteriovenous shunt flow was confirmed using indocyanine green videoangiography. Occlusion in situ preserves the flow to the delicate brainstem perforators and is safer than resection in selected cases like this one.\n                    <jats:italic toggle=\"yes\">Used with permission from Barrow Neurological Institute, Phoenix, Arizona.<\/jats:italic>\n                  <\/jats:p>","DOI":"10.1093\/ons\/opaa092","type":"journal-article","created":{"date-parts":[[2020,4,16]],"date-time":"2020-04-16T07:45:58Z","timestamp":1587023158000},"page":"E423-E423","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Far Lateral Craniotomy and Occlusion In Situ of a Lateral Medullary Arteriovenous Malformation: 2-Dimensional Operative Video"],"prefix":"10.1227","volume":"19","author":[{"given":"Sirin","family":"Gandhi","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Barrow Neurological Institute, St. Joseph's Hospital and Medical Center, Phoenix, Arizona"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin R","family":"Mascitelli","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Barrow Neurological Institute, St. Joseph's Hospital and Medical Center, Phoenix, Arizona"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"Cavallo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Barrow Neurological Institute, St. Joseph's Hospital and Medical Center, Phoenix, Arizona"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali","family":"Tayebi Meybodi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Barrow Neurological Institute, St. Joseph's Hospital and Medical Center, Phoenix, Arizona"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8020-6388","authenticated-orcid":false,"given":"Michael T","family":"Lawton","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Barrow Neurological Institute, St. Joseph's Hospital and Medical Center, Phoenix, Arizona"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2020,10]]},"reference":[{"issue":"1","key":"bib1-20240909","doi-asserted-by":"crossref","first-page":"107","DOI":"10.3171\/2014.8.JNS1483","article-title":"Brainstem arteriovenous malformations: anatomical subtypes, assessment of \u201cocclusion in situ\u201d technique, and microsurgical results","volume":"122","author":"Han","year":"2015","journal-title":"J Neurosurg"},{"issue":"2","key":"bib2-20240909","doi-asserted-by":"crossref","first-page":"42","DOI":"10.1093\/ons\/opy171","article-title":"Right retrosigmoid approach for in situ occlusion of brainstem arteriovenous malformation surrounding the trigeminal nerve: 3-dimensional operative video","volume":"16","author":"Rubio","year":"2019","journal-title":"Oper Neurosurg"}],"container-title":["Operative Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/ons\/article-pdf\/19\/4\/E423\/33919423\/opaa092.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/www.ovid.com\/10.1093\/ons\/opaa092","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T16:51:21Z","timestamp":1786121481000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.1093\/ons\/opaa092"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,4,16]]},"references-count":2,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2020]]}},"URL":"https:\/\/doi.org\/10.1093\/ons\/opaa092","relation":{},"ISSN":["2332-4252","2332-4260"],"issn-type":[{"value":"2332-4252","type":"print"},{"value":"2332-4260","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,4,16]]},"assertion":[{"value":"2019-08-16","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2020-02-14","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
