Abstract

Background: Patients with aortic arch lesions involving the left subclavian artery (LSA) usually require endovascular surgery. The Castor single-branch stent graft provides a targeted solution for such cases, with potential benefits enhanced by the direction-turnover and unwrapping techniques.

Objectives: To evaluate the safety, efficacy and short-term outcomes of the direction-turnover joint unwrapping techniques combined with a Castor single-branch stent graft in treating aortic arch lesions involving the LSA.

Material and methods: From January 2022 to June 2023, 18 patients with aortic arch and LSA lesions underwent Castor stent graft placement at Binzhou Medical University Hospital (Shangdong, China). Preoperative and postoperative imaging with computed tomography angiography (CTA) was used to assess stent placement and efficacy at 1, 3, 6, and 12 months post-surgery.

Results: All 18 patients successfully received the stent graft without intraoperative complications, stent migration or residual shunting. Postoperative imaging confirmed accurate stent placement with no evidence of thrombosis or endoleaks.

Conclusions: The direction-turnover and unwrapping techniques improve the accuracy and safety of Castor stent graft placement, effectively reducing guidewire entanglement and enhancing procedural success. These techniques show promise for broader application in complex aortic arch interventions.

加强蓖麻支架植入：一种使用方向转换和解包裹技术的新方法。

背景：主动脉弓病变累及左锁骨下动脉（LSA）的患者通常需要血管内手术。Castor单支支架移植为此类病例提供了一种有针对性的解决方案，其潜在的益处通过方向转换和解开技术得到增强。目的：评价方向翻转关节解包裹技术联合Castor单支支架治疗主动脉弓累及LSA病变的安全性、有效性和近期疗效。材料和方法：2022年1月至2023年6月，18例主动脉弓和LSA病变患者在山东滨州医学院附属医院行蓖麻支架置入术。术前和术后ct血管造影（CTA）成像用于评估支架放置和术后1、3、6和12个月的疗效。结果：18例患者均成功完成支架移植，无术中并发症、支架移位及残余分流。术后影像学证实支架置入准确，无血栓形成或内漏迹象。结论：方向翻转和解包裹技术提高了Castor支架置入的准确性和安全性，有效减少导丝缠绕，提高手术成功率。这些技术有望在复杂主动脉弓介入治疗中得到更广泛的应用。

期刊介绍： Advances in Clinical and Experimental Medicine has been published by the Wroclaw Medical University since 1992. Establishing the medical journal was the idea of Prof. Bogumił Halawa, Chair of the Department of Cardiology, and was fully supported by the Rector of Wroclaw Medical University, Prof. Zbigniew Knapik. Prof. Halawa was also the first editor-in-chief, between 1992-1997. The journal, then entitled "Postępy Medycyny Klinicznej i Doświadczalnej", appeared quarterly. Prof. Leszek Paradowski was editor-in-chief from 1997-1999. In 1998 he initiated alterations in the profile and cover design of the journal which were accepted by the Editorial Board. The title was changed to Advances in Clinical and Experimental Medicine. Articles in English were welcomed. A number of outstanding representatives of medical science from Poland and abroad were invited to participate in the newly established International Editorial Staff. Prof. Antonina Harłozińska-Szmyrka was editor-in-chief in years 2000-2005, in years 2006-2007 once again prof. Leszek Paradowski and prof. Maria Podolak-Dawidziak was editor-in-chief in years 2008-2016. Since 2017 the editor-in chief is prof. Maciej Bagłaj. Since July 2005, original papers have been published only in English. Case reports are no longer accepted. The manuscripts are reviewed by two independent reviewers and a statistical reviewer, and English texts are proofread by a native speaker. The journal has been indexed in several databases: Scopus, Ulrich’sTM International Periodicals Directory, Index Copernicus and since 2007 in Thomson Reuters databases: Science Citation Index Expanded i Journal Citation Reports/Science Edition. In 2010 the journal obtained Impact Factor which is now 1.179 pts. Articles published in the journal are worth 15 points among Polish journals according to the Polish Committee for Scientific Research and 169.43 points according to the Index Copernicus. Since November 7, 2012, Advances in Clinical and Experimental Medicine has been indexed and included in National Library of Medicine’s MEDLINE database. English abstracts printed in the journal are included and searchable using PubMed http://www.ncbi.nlm.nih.gov/pubmed.
