In this report, we describe two cases of extracranial vertebral artery (VA) to middle cerebral artery (MCA) high-flow bypass using an RA graft with an artificial vessel as an alternative bypass technique.<\/jats:p>\n                  <jats:p>Methods\u2003The patient was placed supine with a head rotation of 80\u2009degrees. After frontotemporal craniotomy, another C-shaped skin incision was made at the retroauricular region and the V3 portion of the VA was exposed at the suboccipital triangle. Prior to attempting the high-flow bypass, the superficial temporal artery (STA) was anastomosed to the M4 portion of the MCA as an insurance bypass. The RA graft was anastomosed to the V3 portion of the VA that traveled under the periosteum at the supra-auricular region through an artificial vessel. After RA-M2 anastomosis, an alternative EC-IC bypass, the V3-RA-M2 bypass, was achieved.<\/jats:p>\n                  <jats:p>Results\u2003Postoperative angiography demonstrated successful graft patency and no perioperative complications were observed in both cases.<\/jats:p>\n                  <jats:p>Conclusions\u2003In the cases where a high-flow bypass is required, the V3 portion of the VA is a suitable alternative proximal anastomosis site when the ECA is not a candidate donor. Furthermore, an artificial vessel shows satisfactory protection against graft complications.<\/jats:p>","DOI":"10.1055\/s-0043-1775989","type":"journal-article","created":{"date-parts":[[2023,10,13]],"date-time":"2023-10-13T19:05:46Z","timestamp":1697223946000},"page":"099-104","source":"Crossref","is-referenced-by-count":3,"title":["Alternative Bypass Technique Using Radial Artery Graft between V3 Segment of Vertebral Artery and Middle Cerebral Artery: Technical Note"],"prefix":"10.1055","volume":"86","author":[{"given":"Yasuhiro","family":"Ito","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kashiwaba Neurosurgical Hospital, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katsuhiko","family":"Maruichi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kashiwaba Neurosurgical Hospital, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoki","family":"Nakayama","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kashiwaba Neurosurgical Hospital, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroyuki","family":"Kobayashi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kashiwaba Neurosurgical Hospital, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryota","family":"Tatezawa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kashiwaba Neurosurgical Hospital, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinitirou","family":"Shinada","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kashiwaba Neurosurgical Hospital, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shunsuke","family":"Terasaka","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kashiwaba Neurosurgical Hospital, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2023,10,13]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"265","DOI":"10.1016\/j.wneu.2018.06.101","article-title":"Extracranial-intracranial high-flow bypass for giant ruptured paraclinoid aneurysm with concomitant bilateral internal carotid artery stenotic dissection","volume":"117","author":"V B Georgieva","year":"2018","journal-title":"World Neurosurg"},{"issue":"04","key":"ref2","doi-asserted-by":"crossref","first-page":"1042","DOI":"10.1097\/SCS.0000000000004422","article-title":"High-flow extracranial-intracranial bypass for giant cavernous carotid aneurysm","volume":"29","author":"J Chen","year":"2018","journal-title":"J Craniofac Surg"},{"issue":"04","key":"ref3","doi-asserted-by":"crossref","first-page":"424","DOI":"10.1016\/j.wneu.2015.01.019","article-title":"Radical removal of recurrent malignant meningeal tumors of the cavernous sinus in combination with high-flow bypass","volume":"83","author":"M Wanibuchi","year":"2015","journal-title":"World Neurosurg"},{"issue":"S 01","key":"ref4","first-page":"66","article-title":"Changing treatment strategy from clipping to radial artery graft bypass and parent artery sacrifice in patients with ruptured blister-like internal carotid artery aneurysms","volume":"10","author":"K Kazumata","year":"2014","journal-title":"Neurosurgery"},{"issue":"04","key":"ref5","doi-asserted-by":"crossref","first-page":"781","DOI":"10.3171\/2009.10.JNS09970","article-title":"Acute extracranial-intracranial bypass using a radial artery graft along with trapping of a ruptured blood blister\u2013like aneurysm of the internal carotid artery.
