We report a 76-year-old female with ATAAD having thrombosed false lumen who underwent emergency hemiarch replacement with primary tear resection on the ascending aorta. After distal anastomosis, a sudden and severe drop in bilateral lower limb oxygen saturation was observed, indicating malperfusion. Subsequent angiography revealed significant stenosis of the descending aorta and iliac arteries. To avoid the additional risk of curative total arch replacement, we planned to insert stent grafts instead, restoring the flow. Follow-up computed tomography confirmed complete resolution of malperfusion. Early intraoperative diagnosis and prompt intervention were crucial in this complex situation. This case underscores the importance of prompt management for intraoperative malperfusion.<\/jats:p>","DOI":"10.1093\/icvts\/ivaf149","type":"journal-article","created":{"date-parts":[[2025,6,29]],"date-time":"2025-06-29T06:02:42Z","timestamp":1751176962000},"source":"Crossref","is-referenced-by-count":0,"title":["An intraoperative nightmare: sudden bilateral lower limb malperfusion during type A acute aortic dissection surgery"],"prefix":"10.1093","volume":"40","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-2913-7717","authenticated-orcid":false,"given":"Koki","family":"Tamaoka","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Surgery, Hamamatsu Rosai Hospital , Hamamatsu-city,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0781-538X","authenticated-orcid":false,"given":"Takeshi","family":"Shimamoto","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Hamamatsu Rosai Hospital , Hamamatsu-city,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Makoto","family":"Takehara","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Hamamatsu Rosai Hospital , Hamamatsu-city,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4756-9395","authenticated-orcid":false,"given":"Kazuhisa","family":"Sakamoto","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Hamamatsu Rosai Hospital , Hamamatsu-city,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,6,24]]},"reference":[{"key":"2025070415361093000_ivaf149-B1","doi-asserted-by":"crossref","first-page":"759","DOI":"10.1177\/02184923231203753","article-title":"Clinical impact of turn-up anastomosis in the treatment of type A acute aortic dissection","volume":"31","author":"Shimamoto","year":"2023","journal-title":"Asian Cardiovasc Thorac Ann"},{"key":"2025070415361093000_ivaf149-B2","doi-asserted-by":"crossref","first-page":"2628","DOI":"10.1016\/j.jacc.2015.04.030","article-title":"The impact of pre-operative malperfusion on outcome in acute type A aortic dissection: results from the GERAADA registry","volume":"65","author":"Czerny","year":"2015","journal-title":"J Am Coll Cardiol"},{"key":"2025070415361093000_ivaf149-B3","doi-asserted-by":"crossref","first-page":"711","DOI":"10.1067\/mva.2000.110054","article-title":"Aortic fenestration for acute or chronic aortic dissection: an uncommon but effective procedure","volume":"32","author":"Panneton","year":"2000","journal-title":"J Vasc Surg"},{"key":"2025070415361093000_ivaf149-B4","doi-asserted-by":"crossref","first-page":"135","DOI":"10.1007\/s002709900349","article-title":"Chronic aortic dissection: stenting of aortic true lumen obliteration with late dynamic variations of both lumens","volume":"22","author":"Nyman","year":"1999","journal-title":"Cardiovasc Intervent Radiol"},{"key":"2025070415361093000_ivaf149-B5","doi-asserted-by":"crossref","first-page":"209","DOI":"10.1510\/icvts.2008.201558","article-title":"Clinical significance of anastomotic leak in ascending aortic replacement for acute aortic dissection","volume":"9","author":"Tanaka","year":"2009","journal-title":"Interact CardioVasc Thorac Surg"}],"container-title":["Interdisciplinary CardioVascular and Thoracic Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/icvts\/advance-article-pdf\/doi\/10.1093\/icvts\/ivaf149\/63569363\/ivaf149.pdf","content-type":"application\/pdf","content-version":"am","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/icvts\/article-pdf\/40\/7\/ivaf149\/63569363\/ivaf149.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/icvts\/article-pdf\/40\/7\/ivaf149\/63569363\/ivaf149.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,7,4]],"date-time":"2025-07-04T19:36:19Z","timestamp":1751657779000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/icvts\/article\/doi\/10.1093\/icvts\/ivaf149\/8172731"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,6,24]]},"references-count":5,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2025,7,2]]}},"URL":"https:\/\/doi.org\/10.1093\/icvts\/ivaf149","relation":{},"ISSN":["2753-670X"],"issn-type":[{"type":"electronic","value":"2753-670X"}],"subject":[],"published-other":{"date-parts":[[2025,7]]},"published":{"date-parts":[[2025,6,24]]},"article-number":"ivaf149"}}
