We present a case of CCA occlusion treated with high-flow vertebral artery (VA) to middle cerebral artery (MCA) bypass using a radial artery (RA) graft. A 68-year-old man experienced recurrent ischemic events in the months preceding surgery. Preoperative diffusion-weighted imaging showed left anterior border zone infarction, and single-photon emission computed tomography revealed severe hemispheric hypoperfusion. Digital subtraction angiography confirmed complete occlusion of the left CCA with inadequate external carotid artery supply. A VA (V3 segment)-RA-MCA (M2 segment) bypass was performed, resulting in an uneventful postoperative course. Follow-up angiography demonstrated durable patency of the radial artery graft. No recurrent ischemic events were observed during the 2-year follow-up period. This technical note demonstrates key surgical considerations for VA-RA-MCA high-flow bypass as a salvage technique in a patient with symptomatic CCA occlusion.<\/jats:p>","DOI":"10.3340\/jkns.2025.0278","type":"journal-article","created":{"date-parts":[[2026,2,23]],"date-time":"2026-02-23T02:24:21Z","timestamp":1771813461000},"page":"822-828","update-policy":"https:\/\/doi.org\/10.3340\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["High-Flow Bypass with Vertebral Artery (V3) to Middle Cerebral Artery (M2) Bypass Using Radial Artery Graft for Common Carotid Artery Occlusion"],"prefix":"10.3340","volume":"69","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-6017-3038","authenticated-orcid":true,"given":"Jae Seong","family":"Hong","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Kyung Hee University Hospital, Kyung Hee University College of Medicine, Seoul, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5091-6760","authenticated-orcid":true,"given":"Jiwook","family":"Ryu","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kyung Hee University Hospital, Kyung Hee University College of Medicine, Seoul, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-3205-136X","authenticated-orcid":true,"given":"Ju In","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kyung Hee University Hospital, Kyung Hee University College of Medicine, Seoul, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9945-8254","authenticated-orcid":true,"given":"Seok Keun","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kyung Hee University Hospital, Kyung Hee University College of Medicine, Seoul, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1892","reference":[{"key":"ref1","first-page":"198595","type":"journal-article","volume-title":"Common carotid artery occlusion: a case series","author":"Bajk\u00f3","year":"2013"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1055\/s-2005-868159","type":"journal-article"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1007\/s00701-019-04001-4","type":"journal-article"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1186\/s42155-020-0097-6","type":"journal-article"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1055\/s-0043-1775989","type":"journal-article"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2013.06.006","type":"journal-article"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.3171\/foc\/2008\/24\/2\/e5","type":"journal-article"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.jocn.2020.04.104","type":"journal-article"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.7863\/jum.2012.31.10.1561","type":"journal-article"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.25259\/sni_99_2021","type":"journal-article"},{"key":"ref11","first-page":"363","type":"journal-article","volume-title":"Common carotid occlusion.
