Lateral positioning allows for gravity-assisted access to the interhemispheric fissure without retractors. The parieto-occipital trajectory is useful in patients who have a steep tentorial angle and avoids manipulation of the occipital lobe and visual cortex. In addition, the authors utilize an angled endoscope, which allows full inspection of the resection bed after AVM removal to visualize areas hidden from the microsurgical view to minimize the chance of residual disease in a deep corridor with multiple visual obstructions.<\/jats:p>\n                  <jats:p>\n                    The video can be found here:\n                    <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/youtu.be\/hk9nIIdtqbI\">https:\/\/youtu.be\/hk9nIIdtqbI<\/jats:ext-link>\n                  <\/jats:p>","DOI":"10.3171\/2020.10.focvid2067","type":"journal-article","created":{"date-parts":[[2021,1,1]],"date-time":"2021-01-01T15:29:33Z","timestamp":1609514973000},"page":"V9","source":"Crossref","is-referenced-by-count":2,"title":["Endoscopic-assisted parieto-occipital interhemispheric precuneal transtentorial approach for microsurgical resection of vermian arteriovenous malformation: operative video and technical nuances"],"prefix":"10.3171","volume":"4","author":[{"given":"Kevin","family":"Zhao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph","family":"Quillin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James K.","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"1)(suppl 1","key":"b1","series-title":"Neurosurgery","first-page":"ONS41","article-title":"Posterior interhemispheric approach: surgical technique, application to vascular lesions, and benefits of gravity retraction","volume":"59","author":"Chi JH","year":"2006","unstructured":"Chi JH, Lawton MT.
