The "GuideLiner" is an easy-to-use catheter designed for deep seating in coronary arteries. The GuideLiner can be used to provide extra guidance support for equipment delivery during difficult coronary interventions or for coaxial alignment in tortuous vessels. There are a few GuideLiner-related complications reported in the literature, which include stent damage on advancement or on withdrawal, dissection, pressure dampening and ischemia, kinking of the balloon, and displacement of the GuideLiner catheter distal marker. We report another unique and previously unreported GuideLiner-related complication and its successful management. In our case, we experienced dislodgment of the distal cylinder of the GuideLiner from the push rod into the aortic root. The embolized cylinder was removed percutaneously using a novel approach without any complications.
“导向鞘管”是一种易于使用的导管，设计用于在冠状动脉中实现深度就位。导向鞘管可用于在困难的冠状动脉介入治疗期间为器械输送提供额外的导向支持，或用于在迂曲血管中实现同轴对齐。文献中报道了一些与导向鞘管相关的并发症，包括推进或回撤过程中的支架损伤、夹层形成、压力衰减和缺血、球囊扭结以及导向鞘管导管远端标记移位。我们报告了另一种独特且此前未报道过的与导向鞘管相关的并发症及其成功处理方法。在我们的病例中，我们遇到导向鞘管远端圆柱体从推杆上脱落并进入主动脉根部的情况。使用一种新颖的方法经皮取出了栓塞的圆柱体，未出现任何并发症。
