However, on computed tomography images, ligamentum arteriosum calcification is often mistaken for esophageal perforation when a patient has a medical history of foreign body ingestion. Ligamentum arteriosum calcification is uncommon in clinical practice. In this case report, we confirm the presence of this condition intraoperatively, which has seldom been reported previously. Increased awareness of the clinical characteristics of this uncommon disease can help thoracic surgeons with proper patient management.<\/jats:p>","DOI":"10.1177\/0300060520925715","type":"journal-article","created":{"date-parts":[[2020,5,19]],"date-time":"2020-05-19T06:59:45Z","timestamp":1589871585000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Ligamentum arteriosum calcification that presented as an esophageal perforation caused by duck bone ingestion"],"prefix":"10.1177","volume":"48","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7537-1979","authenticated-orcid":false,"given":"Xiang-Yu","family":"Chu","sequence":"first","affiliation":[{"name":"Department of Thoracic Surgery, Beijing Friendship Hospital Affiliated to Capital Medical University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7801-2480","authenticated-orcid":false,"given":"Yong","family":"Cui","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Beijing Friendship Hospital Affiliated to Capital Medical University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2617-2911","authenticated-orcid":false,"given":"Zhi","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Beijing Friendship Hospital Affiliated to Capital Medical University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,5,19]]},"reference":[{"key":"bibr1-0300060520925715","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.156.2.1898812"},{"key":"bibr2-0300060520925715","first-page":"51","volume":"131","author":"Durst-Zivkovic B.","year":"1972","journal-title":"Anat Anz"},{"key":"bibr3-0300060520925715","doi-asserted-by":"publisher","DOI":"10.1007\/s10554-012-0058-9"},{"key":"bibr4-0300060520925715","doi-asserted-by":"publisher","DOI":"10.4166\/kjg.2015.66.5.255"},{"key":"bibr5-0300060520925715","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2015.11.055"},{"key":"bibr6-0300060520925715","doi-asserted-by":"publisher","DOI":"10.1016\/j.suc.2013.10.003"},{"key":"bibr7-0300060520925715","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.160.4.8456662"},{"key":"bibr8-0300060520925715","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejcts.2010.01.030"},{"key":"bibr9-0300060520925715","doi-asserted-by":"publisher","DOI":"10.1111\/j.1442-2050.2009.01017.x"}],"container-title":["Journal of International Medical Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0300060520925715","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/0300060520925715","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0300060520925715","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:46:18Z","timestamp":1777459578000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/0300060520925715"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,5]]},"references-count":9,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2020,5]]}},"alternative-id":["10.1177\/0300060520925715"],"URL":"https:\/\/doi.org\/10.1177\/0300060520925715","relation":{},"ISSN":["0300-0605","1473-2300"],"issn-type":[{"value":"0300-0605","type":"print"},{"value":"1473-2300","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,5]]},"article-number":"0300060520925715"}}
