Abstract

Purpose: This study aims to present our experience with superselective embolization of the anterior spinal artery-bearing segmental artery (ASAbSA) using a microvascular plug (MVP) during the minimally invasive segmental artery coil embolization (MISACE) procedure prior endovascular repair of the thoracoabdominal aortic aneurysms.

Methods: We retrospectively evaluated all MISACE procedures performed between May 2018 and July 2023, where MVP was deployed into an angiographically confirmed ASAbSA. Data were analyzed regarding interventional details, technical aspects, and safety protocols. The standard procedure for MVP embolization involves detaching the plug after 10 min, provided no neurological symptoms occur.

Results: A total of 22 patients underwent MVP deployment into the proximal segmental artery supplying the ASAbSA. There were no instances of non-target embolization or segmental artery dissection. Furthermore, none of the patients experienced temporary or permanent spinal cord ischemia.

Conclusion: MVP deployment into the ASAbSA is a safe strategy for protecting the spinal cord during preemptive embolization of segmental arteries prior to endovascular aortic repair.

主动脉支架置入术前脊髓前动脉支段微血管栓塞术：技术与安全性

目的：本研究旨在介绍我们在胸腹主动脉瘤血管内修复前的微创节段动脉线圈栓塞术（MISACE）中使用微血管塞（MVP）对脊柱前动脉携带节段动脉（ASAbSA）进行超选择性栓塞的经验：我们回顾性评估了 2018 年 5 月至 2023 年 7 月期间进行的所有 MISACE 手术，其中 MVP 被部署到血管造影证实的 ASAbSA。我们分析了有关介入细节、技术方面和安全协议的数据。MVP 栓塞的标准程序是在 10 分钟后分离栓塞，前提是没有出现神经症状：共有 22 名患者在供应 ASAbSA 的近端节段动脉中进行了 MVP 部署。没有发生非目标栓塞或节段动脉夹层。此外，没有一名患者出现暂时性或永久性脊髓缺血：结论：在血管内主动脉修复前对节段动脉进行先期栓塞时，将 MVP 植入 ASAbSA 是保护脊髓的安全策略。

期刊介绍： CardioVascular and Interventional Radiology (CVIR) is the official journal of the Cardiovascular and Interventional Radiological Society of Europe, and is also the official organ of a number of additional distinguished national and international interventional radiological societies. CVIR publishes double blinded peer-reviewed original research work including clinical and laboratory investigations, technical notes, case reports, works in progress, and letters to the editor, as well as review articles, pictorial essays, editorials, and special invited submissions in the field of vascular and interventional radiology. Beside the communication of the latest research results in this field, it is also the aim of CVIR to support continuous medical education. Articles that are accepted for publication are done so with the understanding that they, or their substantive contents, have not been and will not be submitted to any other publication.
