Methods: We retrospectively reviewed 57 patients with TBAD who underwent either three dimensional (3D)-printing-assisted extracorporeal fenestration (n = 32) or conventional extracorporeal fenestration (n = 25) from December 2021 to January 2023. We compared their demographic characteristics, operative time, technical success rate, complication rate, secondary intervention rate, mortality rate, and aortic remodeling. Results: Compared with the conventional group, the 3D-printing-assisted group had a significantly shorter operative time (147.84 \u00b1 33.94 min vs. 223.40 \u00b1 65.93 min, p &lt; 0.001), a significantly lower rate of immediate endoleak (3.1% vs. 24%, p = 0.048) and a significantly higher rate of true lumen diameter expansion in the stent-graft segment (all p &lt; 0.05), but a significantly longer stent graft modification time (37.63 \u00b1 2.99 min vs. 28.4 \u00b1 2.12 min, p &lt; 0.001). There were no significant differences in other outcomes between the two groups (p &gt; 0.05). The degree of false lumen thrombosis was higher in the stent-graft segment than in the non-stent-graft segment in both groups and the difference was statistically significant (X2 = 5.390, 4.878; p = 0.02, 0.027). Conclusions: Both techniques are safe and effective for TBAD with an undesirable proximal landing zone. The 3D-printing-assisted extracorporeal fenestration TEVAR technique has advantages in operative time, endoleak risk, and aortic remodeling, while the traditional extracorporeal fenestration TEVAR technique has advantages in stent modification.<\/jats:p>","DOI":"10.59958\/hsf.5885","type":"journal-article","created":{"date-parts":[[2023,8,23]],"date-time":"2023-08-23T22:59:40Z","timestamp":1692831580000},"page":"E363-E371","source":"Crossref","is-referenced-by-count":4,"title":["3D Printing-Assisted versus Conventional Extracorporeal Fenestration Tevar for Stanford Type B Arteries Dissection with Undesirable Proximal Anchoring Zone: Efficacy Analysis"],"prefix":"10.31083","volume":"26","author":[{"given":"Rongyi","family":"Zheng","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fangtao","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cunwei","family":"Cheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weihua","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haojie","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"He","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qianqian","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huayuan","family":"Xi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kailin","family":"Shen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haibin","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2023,8,23]]},"container-title":["The Heart Surgery Forum"],"original-title":[],"link":[{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/5885\/8405","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/5885\/8405","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,17]],"date-time":"2025-10-17T08:40:53Z","timestamp":1760690453000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.imrpress.com\/journal\/HSF\/26\/4\/10.59958\/hsf.5885"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,8,23]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2023,7,4]]}},"URL":"https:\/\/doi.org\/10.59958\/hsf.5885","relation":{},"ISSN":["1522-6662","1098-3511"],"issn-type":[{"value":"1522-6662","type":"electronic"},{"value":"1098-3511","type":"print"}],"subject":[],"published":{"date-parts":[[2023,8,23]]}}}
