Aortic remodeling was assessed using the true lumen area ratio at five predefined anatomical planes. Branch artery perfusion patterns and procedure-related complications were evaluated preoperatively and at 3-month follow-up.Results:At 3 months, the integrated stent-graft group demonstrated significantly higher true lumen area ratios at the left subclavian artery plane 0.60 (0.41, 0.63) vs. 0.41 (0.25, 0.54), p = 0.002; pulmonary artery plane 0.65 (0.54, 0.71) vs. 0.44 (0.38, 0.53), p &lt; 0.001; and diaphragmatic plane 0.61 (0.50, 0.76) vs. 0.44 (0.37, 0.51), p &lt; 0.001. No significant differences were observed at the renal or iliac planes. Regarding branch perfusion, a significant overall difference in postoperative perfusion pattern distribution was observed for the celiac trunk (p = 0.027) and left renal artery (p = 0.017). No differences were detected in other branch arteries. The incidence of postoperative new entry tears was lower in the integrated stent-graft group (23.5% vs. 41.2%), although this difference did not reach statistical significance (p = 0.079).Conclusions:In this exploratory retrospective study with short-term (3-month) follow-up, the integrated stent-graft system was associated with improved early true lumen remodeling in the proximal and mid-aortic segments and differences in branch artery perfusion patterns compared with a conventional covered stent-graft alone. A trend toward fewer new entry tears was observed, but given the limited follow-up and sample size, these findings should be considered preliminary. Confirmation in larger prospective studies with long-term follow-up is warranted to determine whether these early imaging changes translate into durable clinical benefit.<\/jats:p>","DOI":"10.31083\/rcm49740","type":"journal-article","created":{"date-parts":[[2026,7,7]],"date-time":"2026-07-07T11:06:15Z","timestamp":1783422375000},"source":"Crossref","is-referenced-by-count":0,"title":["Comparative Efficacy of Integrated Stent-Graft versus Conventional Covered Stent-Graft Alone in Type B Aortic Dissection: A Retrospective Study Focusing on Aortic Remodeling and Branch Perfusion"],"prefix":"10.31083","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-5269-8347","authenticated-orcid":true,"given":"Jieyu","family":"Cao","sequence":"first","affiliation":[{"name":"Department of Cardiothoracic Surgery, The First Affiliated Hospital, Hengyang Medical School, University of South China, 421001 Hengyang, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5666-4135","authenticated-orcid":true,"given":"Zhengwen","family":"Lei","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, The First Affiliated Hospital, Hengyang Medical School, University of South China, 421001 Hengyang, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keke","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Nursing, University of South China, 421001 Hengyang, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-4638-2326","authenticated-orcid":true,"given":"Shuangxi","family":"He","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, The Second Affiliated Hospital, Hengyang Medical School, University of South China, 421001 Hengyang, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Hu","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, The Second Affiliated Hospital, Hengyang Medical School, University of South China, 421001 Hengyang, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linfei","family":"Xing","sequence":"additional","affiliation":[{"name":"Hengyang Medical School, University of South China, 421001 Hengyang, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Luo","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, The First Affiliated Hospital, Hengyang Medical School, University of South China, 421001 Hengyang, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2026,6,24]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","unstructured":"Rajiah Rajiah PS. \"Uncomplicated\" Type B Aortic Dissection: It's Complicated.
