We present a case of a chronic total occlusion that required the use of a 5 Fr in a 6 Fr guiding catheter. The 5 Fr in a 6 Fr guiding catheter method allows ultra-deep seating to increase backup support and assist stent delivery. This technique was paramount in this case, as there were technical challenges with failure to track drug-eluting stents due to vessel tortuosity and lack of support.
我们报告了一例慢性完全闭塞病例，该病例需要在6F引导导管中使用5F导管。6F引导导管中使用5F导管的方法可实现超深置入，以增加支撑力并辅助支架输送。在该病例中，这项技术至关重要，因为由于血管迂曲和缺乏支撑，在追踪药物洗脱支架时遇到了技术难题。
