The most common cause is subclavian stenosis; however, reversal of flow in the vertebral artery can occur regardless of any detection of anatomic deterioration. In this series, we report three asymptomatic cases where the extracranial Doppler scan preceding off-pump coronary arterial bypass grafting showed isolated reversal of flow in the vertebral artery. No signs of subclavian stenosis or steal syndrome were elicited. However, all patients subsequently suffered from a posterior circulation stroke following off-pump coronary arterial bypass grafting but recovered fully with medical management. We conclude that a detailed pre-operative neurological investigation can mitigate this risk and improve neurological outcomes following off-pump coronary arterial bypass grafting.<\/jats:p>","DOI":"10.1177\/02184923211006322","type":"journal-article","created":{"date-parts":[[2021,4,4]],"date-time":"2021-04-04T13:44:03Z","timestamp":1617543843000},"page":"329-331","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Isolated reversal of flow in the vertebral artery \u2013 A missed entity"],"prefix":"10.1177","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2367-6962","authenticated-orcid":false,"given":"Koushik","family":"Kannan","sequence":"first","affiliation":[{"name":"Department of Cardiothoracic Surgery, G Kuppuswamy Naidu Memorial Hospital, Coimbatore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6224-6493","authenticated-orcid":false,"given":"Ramanish","family":"Ravishankar","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Edinburgh, Edinburgh, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Srinivasan","family":"Muralidharan","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, G Kuppuswamy Naidu Memorial Hospital, Coimbatore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,4,4]]},"reference":[{"key":"bibr1-02184923211006322","doi-asserted-by":"publisher","DOI":"10.7863\/ultra.32.11.1945"},{"key":"bibr2-02184923211006322","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.113.004188"},{"key":"bibr3-02184923211006322","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.2006.105767"},{"key":"bibr4-02184923211006322","first-page":"2423","volume":"7","author":"Iqbal S.","year":"2013","journal-title":"J Clin Diagnostic Res"},{"key":"bibr5-02184923211006322","first-page":"365","volume":"30","author":"da Costa MAC","year":"2015","journal-title":"Rev Bras Cir Cardiovasc"}],"container-title":["Asian Cardiovascular and Thoracic Annals"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/02184923211006322","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/02184923211006322","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/02184923211006322","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T19:27:51Z","timestamp":1777404471000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/02184923211006322"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,4,4]]},"references-count":5,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2022,3]]}},"alternative-id":["10.1177\/02184923211006322"],"URL":"https:\/\/doi.org\/10.1177\/02184923211006322","relation":{},"ISSN":["0218-4923","1816-5370"],"issn-type":[{"value":"0218-4923","type":"print"},{"value":"1816-5370","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,4,4]]}}}
