They usually drain to the basal vein of Rosenthal, and arterial feeders can arise from the anterior choroidal artery and its branches, or from the posterior cerebral artery. If the AVM is more posterior in the parahippocampal gyrus, there is a predominance of arterial feeders arising from P2P or P3 segments of the posterior cerebral artery. As posterior AVMs are difficult to reach using anterior approaches, the supracerebellar transtentorial approach provides a direct pathway to the malformation, allowing better visualization and exposure of the vascular anatomy.<\/jats:p>\n                  <jats:p>\u2003In this video, we present a 29-yr-old woman with a left parahippocampal AVM with P2P arterial feeders and Rosenthal basal vein drainage. The patient had three months of moderate headache and two abrupt seizures before admission. Emergency computed tomography showed intraventricular hemorrhage. Magnetic resonance imaging and cerebral angiography revealed an AVM located in the parahippocampal gyrus, posterior to pulvinar thalamus. The patient underwent microsurgical treatment in semi-sitting position using a supracerebellar and infratentorial approach with transtentorial resection. The AVM was completely removed, and the patient recovered without neurological deficits. The authors present a 3-dimensional video of the microsurgical steps required to perform a transtentorial approach for AVM resection in the parahippocampal gyrus.<\/jats:p>\n                  <jats:p>\u2003The patient signed the Institutional Consent Form, which allows the use of his\/her images and videos for any type of medical publications in conferences and\/or scientific articles.<\/jats:p>","DOI":"10.1093\/ons\/opy294","type":"journal-article","created":{"date-parts":[[2018,11,28]],"date-time":"2018-11-28T11:05:05Z","timestamp":1543403105000},"page":"E83-E84","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":9,"title":["Transtentorial Approach for Parahippocampal Gyrus Arteriovenous Malformation Resection: 3-Dimensional Operative Video"],"prefix":"10.1227","volume":"16","author":[{"given":"Feres","family":"Chaddad-Neto","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Universidade Federal de Sao Paulo, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"},{"name":"Hospital Beneficencia Portuguesa de S\u00e3o Paulo, Sao Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3552-6347","authenticated-orcid":false,"given":"Marcos Devanir Silva","family":"da Costa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Universidade Federal de Sao Paulo, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ricardo Louren\u00e7o","family":"Caramanti","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Universidade Federal de Sao Paulo, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruno Louren\u00e7o","family":"Costa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Universidade Federal de Sao Paulo, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Conrado Feisthauer","family":"Silveira","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Universidade Federal de Sao Paulo, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kleber Gonzales","family":"Echeverria","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Universidade Federal de Sao Paulo, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Maria","family":"Campos Filho","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Universidade Federal de Sao Paulo, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"},{"name":"Hospital Beneficencia Portuguesa de S\u00e3o Paulo, Sao Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ricardo Silva","family":"Centeno","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Universidade Federal de Sao Paulo, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2019,3]]},"container-title":["Operative Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/ons\/article-pdf\/16\/3\/E83\/30214630\/opy294.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/www.ovid.com\/01787389-201903000-00025","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T16:51:13Z","timestamp":1786121473000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/01787389-201903000-00025"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,11,28]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2019]]}},"URL":"https:\/\/doi.org\/10.1093\/ons\/opy294","relation":{},"ISSN":["2332-4252","2332-4260"],"issn-type":[{"value":"2332-4252","type":"print"},{"value":"2332-4260","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,11,28]]},"assertion":[{"value":"2018-01-23","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-08-24","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
