The patients were divided into two groups according to the location of referral source hospitals: the Asahikawa city group (group A, n\u2009=\u200949) and the out-of-the-city group (group O, n\u2009=\u200963). Use of helicopter transfer (n\u2009=\u200913) and cloud-type telemedicine (n\u2009=\u200920) in group O were reviewed as subanalyses.<\/jats:p><jats:p>Transfer distance differed between groups (4.2\u2009\u00b1\u20093.5\u2009km in group A vs 107.3\u2009\u00b1\u200969.2\u2009km in group O; p\u2009=\u20090.0001), but 30-day mortality (10.2% in group A vs 7.9% in group O; p\u2009=\u20090.676) and hospital mortality (12.2% in group A vs 9.5% in group O; p\u2009=\u20090.687) did not differ. Operative outcomes did not differ with or without helicopter and cloud-type telemedicine, but diagnosis-to-operation time was shorter with helicopter (240.0\u2009\u00b1\u200970.8 vs 320.0\u2009\u00b1\u200978.5\u2009minutes; p\u2009=\u20090.031) and telemedicine (242.0\u2009\u00b1\u200975.2 vs 319.0\u2009\u00b1\u200983.8\u2009minutes; p\u2009=\u20090.007).<\/jats:p><jats:p>\n          Conclusion\u2003We found that long-distance transfer did not impair surgical outcomes in AADA patients, and both helicopter transfer and cloud-type telemedicine system could contribute to the reduction of diagnosis-to-operation time in the large Hokkaido area. Further studies are mandatory to investigate if both the systems will improve clinical outcomes.<\/jats:p>","DOI":"10.1055\/a-2031-3763","type":"journal-article","created":{"date-parts":[[2023,2,10]],"date-time":"2023-02-10T00:12:45Z","timestamp":1675987965000},"page":"105-117","source":"Crossref","is-referenced-by-count":6,"title":["Role of Helicopter Transfer and Cloud-Type Imaging for Acute Type A Aortic Dissection"],"prefix":"10.1055","volume":"72","author":[{"given":"Natsuya","family":"Ishikawa","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Asahikawa Medical University, Asahikawa, Hokkaido, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8150-2552","authenticated-orcid":false,"given":"Masahiko","family":"Narita","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Asahikawa Medical University, Asahikawa, Hokkaido, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9429-7025","authenticated-orcid":false,"given":"Tomonori","family":"Shirasaka","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Asahikawa Medical University, Asahikawa, Hokkaido, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryouhei","family":"Ushioda","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Asahikawa Medical University, Asahikawa, Hokkaido, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahiro","family":"Tsutsui","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Asahikawa Medical University, Asahikawa, Hokkaido, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuyoshi","family":"Azuma","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Asahikawa Medical University, Asahikawa, Hokkaido, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Kamiya","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Asahikawa Medical University, Asahikawa, Hokkaido, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2023,3,20]]},"reference":[{"issue":"03","key":"ref1","doi-asserted-by":"crossref","first-page":"735","DOI":"10.1016\/j.jtcvs.2021.04.053","article-title":"2021 The American Association for Thoracic Surgery expert consensus document: surgical treatment of acute type A aortic dissection","volume":"162","author":"S C Malaisrie","year":"2021","journal-title":"J Thorac Cardiovasc Surg"},{"issue":"10","key":"ref2","doi-asserted-by":"crossref","first-page":"1009","DOI":"10.1001\/jamacardio.2022.2718","article-title":"Early mortality in type A acute aortic dissection: insights from the International Registry of Acute Aortic Dissection","volume":"7","author":"K M Harris","year":"2022","journal-title":"JAMA Cardiol"},{"issue":"04","key":"ref3","doi-asserted-by":"crossref","first-page":"957","DOI":"10.1093\/ejcts\/ezab146","article-title":"Risk analysis for early mortality in emergency acute type A aortic dissection surgery: experience of Tokyo Acute Aortic Super-network","volume":"60","author":"M Yamasaki","year":"2021","journal-title":"Eur J Cardiothorac Surg"},{"issue":"14","key":"ref4","first-page":"S153","article-title":"Risk model of thoracic aortic surgery in 4707 cases from a nationwide single-race population through a web-based data entry system: the first report of 30-day and 30-day operative outcome risk models for thoracic aortic surgery","volume":"118","author":"N Motomura","year":"2008","journal-title":"Circulation"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"5692083","DOI":"10.1155\/2019\/5692083","article-title":"Does interhospital transfer influence the outcomes of patients receiving surgery for acute type A aortic dissection?
