We present a case involving a 70-year-old man who presented with recurrent left hemispheric strokes in the setting of a subocclusive left internal carotid stenosis. A left ascending pharyngeal artery with variant origin from the internal carotid artery helped maintain flow distal to the area of stenosis and allowed for safe and successful internal carotid artery stenting. Identification of this variant and recognition of the anastomotic network involving this connection were crucial to determine the safety of stenting. The patient had no further recurrent events and had sustained improvement on his 90-day follow-up.<\/jats:p>","DOI":"10.1136\/bcr-2019-230048","type":"journal-article","created":{"date-parts":[[2019,8,29]],"date-time":"2019-08-29T07:35:03Z","timestamp":1567064103000},"page":"e230048","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Variant ascending pharyngeal artery maintaining flow in a subocclusive internal carotid artery"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6987-1996","authenticated-orcid":false,"given":"Brian D","family":"Kim","sequence":"first","affiliation":[{"name":"Neurology, Icahn School of Medicine at Mount Sinai, New York City, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas J","family":"Oxley","sequence":"additional","affiliation":[{"name":"Neurosurgery, Icahn School of Medicine at Mount Sinai, New York City, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Johanna T","family":"Fifi","sequence":"additional","affiliation":[{"name":"Neurosurgery, Icahn School of Medicine at Mount Sinai, New York City, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hazem","family":"Shoirah","sequence":"additional","affiliation":[{"name":"Neurosurgery, Neurology, Radiology, Icahn School of Medicine at Mount Sinai, New York City, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,8,28]]},"reference":[{"key":"2025082623231182000_12.8.e230048.1","first-page":"1246","article-title":"The ascending pharyngeal artery: branches, anastomoses, and clinical significance","volume":"23","author":"Hacein-Bey","year":"2002","journal-title":"AJNR Am J Neuroradiol"},{"key":"2025082623231182000_12.8.e230048.2","first-page":"ons114","article-title":"The ascending pharyngeal artery and its relevance for neurosurgical and endovascular procedures","volume":"65","author":"Cavalcanti","year":"2009","journal-title":"Neurosurgery"},{"key":"2025082623231182000_12.8.e230048.3","doi-asserted-by":"crossref","first-page":"1181","DOI":"10.1007\/s00276-018-2088-z","article-title":"Ectopic origin of the ascending pharyngeal artery: implications for carotid surgery","volume":"40","author":"De Freitas","year":"2018","journal-title":"Surg Radiol Anat"},{"key":"2025082623231182000_12.8.e230048.4","doi-asserted-by":"crossref","first-page":"893","DOI":"10.1007\/s00276-016-1652-7","article-title":"Extracranial internal carotid artery: anatomical variations in asymptomatic patients","volume":"38","author":"Cappabianca","year":"2016","journal-title":"Surg Radiol Anat"},{"key":"2025082623231182000_12.8.e230048.5","doi-asserted-by":"crossref","first-page":"240.e1","DOI":"10.1016\/j.avsg.2012.10.003","article-title":"Anomalous ascending pharyngeal artery arising from the internal carotid artery: report of three cases","volume":"27","author":"Cort\u00e9s-Franco","year":"2013","journal-title":"Ann Vasc Surg"},{"key":"2025082623231182000_12.8.e230048.6","doi-asserted-by":"crossref","first-page":"1450","DOI":"10.2106\/00004623-197355070-00012","article-title":"The arterial supply of the odontoid process","volume":"55","author":"Schiff","year":"1973","journal-title":"J Bone Joint Surg Am"},{"key":"2025082623231182000_12.8.e230048.7","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-015-2866-4"},{"key":"2025082623231182000_12.8.e230048.8","doi-asserted-by":"crossref","first-page":"157","DOI":"10.1177\/159101999900500208","article-title":"Endarterectomy of an Occluded ICA: short segment occlusion with distal patency maintained by an aberrant ascending pharyngeal artery","volume":"5","author":"Patel","year":"1999","journal-title":"Interv Neuroradiol"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2019-230048","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T06:23:22Z","timestamp":1756275802000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2019-230048"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,8]]},"references-count":8,"journal-issue":{"issue":"8","published-online":{"date-parts":[[2019,8,28]]},"published-print":{"date-parts":[[2019,8]]}},"alternative-id":["10.1136\/bcr-2019-230048"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2019-230048","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,8]]}}}
