During hospitalization, 10 patients developed disease progression, with 2 in-hospital mortality cases. Analysis of the haematoma remodelling rate in 39 patients revealed that such a rate was significantly associated with the reciprocal of the time from onset. Analysis of all 70 CTA examinations performed within 24\u2009h after the onset of IMH showed that haematoma thickness was significantly associated with the logarithm of the time from onset. Initial regression of the haematoma was not necessarily associated with avoidance of disease progression.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>In type A IMH, the thickness of the haematoma in the ascending aorta tended to decrease in the very early period; however, prompt regression of the haematoma was not necessarily associated with avoidance of disease progression.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ejcts\/ezae006","type":"journal-article","created":{"date-parts":[[2024,1,9]],"date-time":"2024-01-09T21:38:10Z","timestamp":1704836290000},"source":"Crossref","is-referenced-by-count":3,"title":["Initial thickness of the crescent may not be a reliable predictor of complications in type A intramural haematoma"],"prefix":"10.1093","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0552-2727","authenticated-orcid":false,"given":"Tadashi","family":"Kitamura","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Surgery, Kitasato University School of Medicine , Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fumiaki","family":"Shikata","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Kitasato University School of Medicine , Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinzo","family":"Torii","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Kitasato University School of Medicine , Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiaki","family":"Mishima","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Kitasato University School of Medicine , Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaomi","family":"Fukuzumi","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Kitasato University School of Medicine , Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yusuke","family":"Motoji","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Kitasato University School of Medicine , Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshimi","family":"Tamura","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Kitasato University School of Medicine , Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sakura","family":"Kaneda","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Kitasato University School of Medicine , Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daiki","family":"Ishiwaki","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Kitasato University School of Medicine , Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kagami","family":"Miyaji","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Kitasato University School of Medicine , Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2024,1,11]]},"reference":[{"key":"2024012615220210200_ezae006-B1","doi-asserted-by":"crossref","first-page":"2873","DOI":"10.1093\/eurheartj\/ehu281","article-title":"2014 ESC guidelines on the diagnosis and treatment of aortic diseases: document covering acute and chronic aortic diseases of the thoracic and abdominal aorta of the adult.
