Addressing proximal complications that arise after endovascular aortic repair for type B aortic dissection, such as type Ia endoleaks, "bird-beaking" of the thoracic endovascular aortic repair (TEVAR) stent, retrograde type A dissection, and postdissection aneurysms, bears considerable complexities. We present a novel and safe method for open arch repair that can ensure a secure and efficient approach for TEVAR complications. The key element of the operative technique is approximating the grafted stent portion to the aortic wall and the arch prosthesis. The technique has successfully been implemented in 11 patients, who received secondary open arch repair from 2019 to 2022 after TEVAR for type B dissection. Our objective is not only to introduce this reliable concept but also to provide a comprehensive demonstration of its advantages and disadvantages compared with currently used open treatment methods and discuss patient outcomes after secondary open arch repair.
处理B型主动脉夹层血管腔内修复术后出现的近端并发症,如Ia型内漏、胸主动脉腔内修复术(TEVAR)支架的“鸟嘴样改变”、逆行A型夹层和夹层后动脉瘤,存在相当大的复杂性。我们提出了一种新颖且安全的开放弓部修复方法,该方法可为TEVAR并发症提供一种安全有效的处理方式。手术技术的关键要素是使移植的支架部分与主动脉壁和弓部假体贴合。该技术已成功应用于11例患者,这些患者在2019年至2022年期间因B型夹层接受TEVAR术后接受了二次开放弓部修复。我们的目的不仅是介绍这一可靠的概念,还将全面展示其与目前使用的开放治疗方法相比的优缺点,并讨论二次开放弓部修复后的患者预后。
