摘要

我们描述了一种球囊轴辅助导尿管交换技术，无需移除原位PTCA导线。在一个复杂的LCX支架内再狭窄的病例中，引导支持不良，6 Fr EBU导管成功地在0.014″PTCA丝跟踪的单轨球囊的金属轴上推进。台架测试证实，该轴能够模拟0.035″硬导线，为安全的导管交换提供足够的支持。该技术消除了锚定或专用导线的需求，为导向交换提供了实用、资源高效的解决方案，特别是在设备可用性有限的环境中。

Balloon Shaft-Assisted Guide Catheter Exchange Without PTCA Wire Removal.

We describe a balloon shaft-assisted technique for guide catheter exchange without removing the in-situ PTCA wire. In a complex LCX in-stent restenosis case with poor guide support, a 6 Fr EBU catheter was successfully advanced over the metallic shaft of a monorail balloon tracked on a 0.014″ PTCA wire. Bench testing confirmed the shaft's ability to mimic a stiff 0.035″ wire, providing adequate support for safe catheter exchange. This technique eliminates the need for anchoring or specialized wires and offers a practical, resource-efficient solution for guide exchange, particularly in settings with limited device availability.
