Transradial approach for percutaneous interventions has emerged as an alternative to transfemoral access which is known to be more associated with vascular local complications. However, lack of guiding-catheter support via the radial access is one of the problems encountering the operators. Many solutions have been proposed to overcome this problem. We report on a 62-year-old man with tight stenosis of the distal part of the right coronary artery. He underwent coronary angiography and then percutaneous angioplasty via the right radial artery. During the procedure, attempts to advance a stent beyond a tortuosity at the level of the second segment failed due to lack of support of the 6-Fr Judkins right 4 guiding catheter, even with the buddy wire technique. Then, switching to a 5-Fr Judkins right 4 guiding catheter allowed safe deep engagement and resulted in successful advancement and deployment of the stent.
经桡动脉途径进行经皮介入治疗已成为经股动脉途径的一种替代方法，众所周知，经股动脉途径与血管局部并发症的关联更大。然而，经桡动脉途径缺乏引导导管的支撑是术者面临的问题之一。人们已经提出了许多解决方案来克服这一问题。我们报告了一名62岁男性，其右冠状动脉远端严重狭窄。他接受了冠状动脉造影，然后通过右桡动脉进行了经皮血管成形术。在手术过程中，即使采用双导丝技术，由于6F Judkins右4引导导管缺乏支撑，试图将支架推进到第二段水平的弯曲处之外仍告失败。然后，改用5F Judkins右4引导导管实现了安全的深部插入，并成功推进和部署了支架。
