He was in cardiogenic shock at arrival. Based on the results of ECG and echocardiogram, he was diagnosed with ST-segment elevation myocardial infarction. Point-of-care ultrasonography (POCUS) did not reveal acute aortic dissection (AAD). During an emergency coronary angiography, aortic dissection was detected and computed tomographic angiography (CTA) revealed Stanford type A AAD with a highly compressed true lumen. Because of this form of aortic dissection, the enlarged false lumen could be potentially misidentified as a normal aorta in POCUS. Although POCUS is useful when AAD is suspected, we should not overestimate its findings and lower the threshold for CTA.<\/jats:p>","DOI":"10.1136\/bcr-2020-239328","type":"journal-article","created":{"date-parts":[[2021,3,2]],"date-time":"2021-03-02T10:57:50Z","timestamp":1614682670000},"page":"e239328","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Acute aortic dissection with highly compressed true lumen: unanticipated pitfall of point-of-care ultrasonography"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9323-656X","authenticated-orcid":false,"given":"Hisashi","family":"Dote","sequence":"first","affiliation":[{"name":"Department of Emergency and Critical Care Medicine, Seirei Hamamatsu Hospital, Hamamatsu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaaki","family":"Koide","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Seirei Hamamatsu Hospital, Hamamatsu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shunsuke","family":"Kobayashi","sequence":"additional","affiliation":[{"name":"Department of Emergency and Critical Care Medicine, Seirei Hamamatsu Hospital, Hamamatsu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takahiro","family":"Atsumi","sequence":"additional","affiliation":[{"name":"Department of Emergency and Critical Care Medicine, Seirei Hamamatsu Hospital, Hamamatsu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,3,2]]},"reference":[{"key":"2025082723221185000_14.3.e239328.1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.117.031264"},{"key":"2025082723221185000_14.3.e239328.2","doi-asserted-by":"crossref","first-page":"880","DOI":"10.1016\/j.jemermed.2017.08.012","article-title":"Diagnosis of aortic dissection presenting as ST-elevation myocardial infarction using point-of-care ultrasound","volume":"53","author":"Chenkin","year":"2017","journal-title":"J Emerg Med"},{"key":"2025082723221185000_14.3.e239328.3","doi-asserted-by":"crossref","first-page":"e13","DOI":"10.1016\/j.jemermed.2017.09.019","article-title":"View from the top: point-of-care ultrasound diagnosis of type A aortic dissection using the suprasternal view","volume":"54","author":"Fernando","year":"2018","journal-title":"J Emerg Med"},{"key":"2025082723221185000_14.3.e239328.4","doi-asserted-by":"crossref","first-page":"171","DOI":"10.1007\/s11739-020-02354-8","article-title":"Diagnosis and management of acute aortic syndromes in the emergency department","volume":"16","author":"Morello","year":"2021","journal-title":"Intern Emerg Med"},{"key":"2025082723221185000_14.3.e239328.5","doi-asserted-by":"publisher","DOI":"10.1007\/s11739-014-1080-9"},{"key":"2025082723221185000_14.3.e239328.6","doi-asserted-by":"crossref","first-page":"643","DOI":"10.1016\/j.jemermed.2015.12.002","article-title":"Evaluation of the aortic arch from the suprasternal Notch view using focused cardiac ultrasound","volume":"50","author":"Kinnaman","year":"2016","journal-title":"J Emerg Med"},{"key":"2025082723221185000_14.3.e239328.7","doi-asserted-by":"publisher","DOI":"10.1161\/CIR.0b013e3181d4739e"},{"key":"2025082723221185000_14.3.e239328.8","doi-asserted-by":"crossref","first-page":"45","DOI":"10.1002\/jgf2.155","article-title":"The diagnostic accuracy of the mediastinal width on supine anteroposterior chest radiographs with nontraumatic Stanford type A acute aortic dissection","volume":"19","author":"Funakoshi","year":"2018","journal-title":"J Gen Fam Med"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2020-239328","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T06:22:16Z","timestamp":1756362136000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2020-239328"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,3]]},"references-count":8,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2021,3,2]]},"published-print":{"date-parts":[[2021,3]]}},"alternative-id":["10.1136\/bcr-2020-239328"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2020-239328","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,3]]}}}
