If not fully understood, patients may be incorrectly counselled regarding the likelihood of respiratory and swallowing symptoms of a vascular ring. An understanding of the circumstances in which a ring can arise is needed. Our study adds to the limited published data on this condition, with a view to improving clinician understanding and guiding accurate prenatal counselling.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1017\/s1047951126113936","type":"journal-article","created":{"date-parts":[[2026,7,13]],"date-time":"2026-07-13T07:19:57Z","timestamp":1783927197000},"page":"1396-1401","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["When does an aberrant right subclavian artery create a vascular ring?"],"prefix":"10.1017","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-6462-9734","authenticated-orcid":false,"given":"Nicola","family":"Boyd","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03zydm450","id-type":"ROR","asserted-by":"publisher"}],"name":"Great Ormond Street Hospital for Children NHS Foundation Trust"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elisabeth","family":"Seidl-Mlczoch","sequence":"additional","affiliation":[{"name":"Medical University of Vienna"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Vazquez-Garcia","sequence":"additional","affiliation":[{"name":"Queen Charlotte\u2019s and Chelsea Hospital"},{"name":"Royal Brompton Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jane","family":"Bromilow","sequence":"additional","affiliation":[{"name":"University Hospital of Wales"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julene","family":"Carvalho","sequence":"additional","affiliation":[{"name":"Royal Brompton Hospital"},{"name":"St George\u2019s Hospital"},{"name":"University of London"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victoria","family":"Jowett","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03zydm450","id-type":"ROR","asserted-by":"publisher"}],"name":"Great Ormond Street Hospital for Children NHS Foundation Trust"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,7,13]]},"reference":[{"key":"S1047951126113936_ref12","unstructured":"12.
