This technical video demonstrates the nuances of an innovative use of flow diversion to treat a recurrent wide-necked PCoA aneurysm. This middle-aged patient presented with recurrence of a previously ruptured, coil-embolized PCoA aneurysm. Initial attempts at Comaneci-assisted coiling were unsuccessful because the coil herniated into the middle cerebral artery (MCA). Therefore, a low-profile visualized intraluminal support (LVIS) was placed in the fetal PCA across the aneurysm ostium and a flow diverter was placed in the internal carotid artery and MCA to constitute a Y-construct.<\/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:\/\/stream.cadmore.media\/r10.3171\/2022.7.FOCVID2262\">https:\/\/stream.cadmore.media\/r10.3171\/2022.7.FOCVID2262<\/jats:ext-link>\n                  <\/jats:p>","DOI":"10.3171\/2022.7.focvid2262","type":"journal-article","created":{"date-parts":[[2022,10,3]],"date-time":"2022-10-03T17:30:12Z","timestamp":1664818212000},"page":"V4","source":"Crossref","is-referenced-by-count":1,"title":["FRED flow diversion with LVIS protection of large posterior communicating artery aneurysm: the \"FRELVIS\" technique"],"prefix":"10.3171","volume":"7","author":[{"given":"Steven B.","family":"Housley","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo;"},{"name":"Department of Neurosurgery, Buffalo General Medical Center, Kaleida Health, Buffalo;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin M.","family":"Cappuzzo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo;"},{"name":"Department of Neurosurgery, Buffalo General Medical Center, Kaleida Health, Buffalo;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad","family":"Waqas","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo;"},{"name":"Department of Neurosurgery, Buffalo General Medical Center, Kaleida Health, Buffalo;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andre","family":"Monteiro","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo;"},{"name":"Department of Neurosurgery, Buffalo General Medical Center, Kaleida Health, Buffalo;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elad I.","family":"Levy","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo;"},{"name":"Department of Neurosurgery, Buffalo General Medical Center, Kaleida Health, Buffalo;"},{"name":"Department of Radiology, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo;"},{"name":"Canon Stroke and Vascular Research Center, University at Buffalo; and"},{"name":"Jacobs Institute, Buffalo, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adnan H.","family":"Siddiqui","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo;"},{"name":"Department of Neurosurgery, Buffalo General Medical Center, Kaleida Health, Buffalo;"},{"name":"Department of Radiology, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo;"},{"name":"Canon Stroke and Vascular Research Center, University at Buffalo; and"},{"name":"Jacobs Institute, Buffalo, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Surg Neurol Int","doi-asserted-by":"publisher","first-page":"88","DOI":"10.4103\/2152-7806.74147","article-title":"A review of the management of posterior communicating artery aneurysms in the modern era","volume":"1","author":"Golshani K","year":"2010","unstructured":"Golshani K, Ferrell A, Zomorodi A, Smith TP, Britz GW.
