The patient was treated with dual-antiplatelet therapy in the hospital and was able to return to work shortly after discharge. The case provides insights into several possibilities for the clinical significance of BA fenestration and its potential causal or contributory relationship with ischaemic stroke of the brainstem.<\/jats:p>","DOI":"10.1136\/bcr-2024-260604","type":"journal-article","created":{"date-parts":[[2024,9,25]],"date-time":"2024-09-25T22:40:14Z","timestamp":1727304014000},"page":"e260604","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Basilar artery fenestration and ischaemic stroke: cause, sieve, or both?"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6647-8099","authenticated-orcid":false,"given":"Kevin","family":"Zhang","sequence":"first","affiliation":[{"name":"Hackensack Meridian School of Medicine, Nutley, New Jersey, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donnie","family":"Bell","sequence":"additional","affiliation":[{"name":"NYC Health and Hospitals Kings County, New York, New York, USA"},{"name":"SUNY Downstate Medical Center College of Medicine, New York, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,9,25]]},"reference":[{"key":"2025082803252160000_17.9.e260604.1","first-page":"62","article-title":"Basilar artery fenestration and ischemic stroke: An unclear causal relationship","volume":"45","author":"El Otmani","year":"2020","journal-title":"J Med Vasc"},{"key":"2025082803252160000_17.9.e260604.2","doi-asserted-by":"crossref","DOI":"10.3389\/fneur.2021.766174","article-title":"Hemodynamic Differences Between Basilar Artery Fenestration and Normal Vertebrobasilar Artery: A Pilot Study","volume":"12","author":"Dong","year":"2021","journal-title":"Front Neurol"},{"key":"2025082803252160000_17.9.e260604.3","doi-asserted-by":"crossref","first-page":"44","DOI":"10.1177\/1591019918793340","article-title":"Successful endovascular recanalization of a partially occluded basilar artery fenestration","volume":"25","author":"Meinel","year":"2019","journal-title":"Interv Neuroradiol"},{"key":"2025082803252160000_17.9.e260604.4","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2017-222910","article-title":"Basilar artery fenestration: an unusual possible cause of ischaemic stroke?","volume":"2018","author":"Wu","year":"2018","journal-title":"BMJ Case Rep"},{"key":"2025082803252160000_17.9.e260604.5","article-title":"An unusual cause of pediatric stroke secondary to congenital basilar artery fenestration","volume":"2013","author":"Gold","year":"2013","journal-title":"Case Rep Crit Care"},{"key":"2025082803252160000_17.9.e260604.6","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2022-249086","article-title":"Recanalisation of an occluded fenestrated branch of a basilar artery","volume":"15","author":"Sousa","year":"2022","journal-title":"BMJ Case Rep"},{"key":"2025082803252160000_17.9.e260604.7","doi-asserted-by":"crossref","DOI":"10.1097\/MD.0000000000027280","article-title":"Vertebral artery hypoplasia as an independent risk factor of posterior circulation atherosclerosis and ischemic stroke","volume":"100","author":"Din\u00e7","year":"2021","journal-title":"Medicine (Balt)"},{"key":"2025082803252160000_17.9.e260604.8","doi-asserted-by":"publisher","DOI":"10.1177\/0897190015615900"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2024-260604","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T10:25:31Z","timestamp":1756376731000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2024-260604"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,9]]},"references-count":8,"journal-issue":{"issue":"9","published-online":{"date-parts":[[2024,9,25]]},"published-print":{"date-parts":[[2024,9]]}},"alternative-id":["10.1136\/bcr-2024-260604"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2024-260604","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2024,9]]}}}
