Clinical outcomes, CT-based morphological parameters, and aortic remodeling were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>There were no significant differences between the two groups regarding mortality or major complications. Patients in the Partial-ET group had greater distal stent angulation (34.5\u2009\u00b1\u20098.9\u00b0 vs. 24.5\u2009\u00b1\u200913.7\u00b0), and no dSINE was observed during a mean follow-up period of 6.4 months. Aortic remodeling outcomes were comparable between the two groups, while the Partial-ET group demonstrated shorter lower body ischemia time and more proximal distal stent deployment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Application of Frozenix Partial-ET resulted in outcomes comparable to those obtained using the conventional device, without an increase in mortality or major complications. Despite a greater distal angulation, no early dSINE was observed during the study period. This device may represent a feasible option in selected cases of acute type A dissection, although further long-term data are needed to clarify its efficacy.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/02184923261440414","type":"journal-article","created":{"date-parts":[[2026,4,15]],"date-time":"2026-04-15T15:09:28Z","timestamp":1776265768000},"page":"445-451","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Early and midterm outcomes of Frozenix Partial-ET versus conventional Frozenix in total arch replacement for acute type A aortic dissection"],"prefix":"10.1177","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9953-1538","authenticated-orcid":false,"given":"Ryumon","family":"Matsumoto","sequence":"first","affiliation":[{"name":"Tsuchiura Kyodo General Hospital"},{"name":"Tokyo Medical University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1104-1628","authenticated-orcid":false,"given":"Ryoji","family":"Kinoshita","sequence":"additional","affiliation":[{"name":"Tsuchiura Kyodo General Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taiju","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Tsuchiura Kyodo General Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yusuke","family":"Shimahara","sequence":"additional","affiliation":[{"name":"Tokyo Medical University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hitoshi","family":"Ogino","sequence":"additional","affiliation":[{"name":"Tokyo Medical University Hospital"},{"name":"Kitano Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,4,15]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2021.04.053"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2019.12.051"},{"key":"e_1_3_2_4_2","article-title":"New graft-implanting method for thoracic aortic aneurysm or dissection with a stented graft","volume":"94","author":"Kato M","year":"1996","unstructured":"Kato M, Ohnishi K, Kaneko M, et al.
