Access-related limitations, namely small-caliber vessels and tortuous or calcified stenotic vessels, are often encountered during endovascular aneurysm repair (EVAR) and thoracic EVAR (TEVAR). Overcoming these limitations often requires the creation of a conduit through which the endovascular devices can be delivered. If these limitations are not recognized and respected preoperatively, significant morbidity and mortality may ensue because access-related complications are often addressed in emergent and chaotic situations. There are a variety of conduits described in the literature, each with their own advantages and disadvantages. The present report explores the use of conduits during EVAR and TEVAR by discussing the current literature, and the authors also describe a preferred method to address unfavorable iliac anatomy through the use of endoconduits.
在血管内动脉瘤修复术（EVAR）和胸主动脉腔内修复术（TEVAR）过程中，经常会遇到与入路相关的限制，即小口径血管以及迂曲或钙化的狭窄血管。克服这些限制通常需要创建一个导管，通过该导管可以输送血管内装置。如果术前未认识到并重视这些限制，可能会导致严重的发病率和死亡率，因为与入路相关的并发症往往在紧急和混乱的情况下处理。文献中描述了多种导管，每种导管都有其自身的优缺点。本报告通过讨论当前文献探讨了EVAR和TEVAR中导管的使用，作者还描述了一种通过使用内导管来处理不利髂部解剖结构的首选方法。
