The aim of this clinical study is to assess the feasibility and safety of the 7 Fr Railway sheathless access system (Cordis Corporation) for complex percutaneous coronary interventions (PCI) using distal radial artery access.
Over a 2-month period, we enrolled 20 patients (all those undergoing complex PCI) where a 7 Fr guide catheter was deemed necessary. Multiple bifurcation techniques and calcified plaque modifying tools were used. The primary endpoint was procedural success (95%) without need for access-site crossover (0%) or major adverse cardiovascular event within the first month (0%), while our secondary endpoint was the access-site complication rate (arterial spasm in 1 case [5%]).
Distal radial access with the 7 Fr Railway sheathless access system was a feasible and safe access option for complex PCI in our very high-risk study population. This approach could be a valuable option for decreasing the risk of a major bleeding event or vascular complication in cases that require a large guide catheter.
本临床研究旨在评估 7Fr Railway 无鞘介入系统（科迪斯公司）用于经远端桡动脉入路行复杂经皮冠状动脉介入治疗（PCI）的可行性和安全性。
在 2 个月的时间内，我们纳入了 20 例患者（均为需使用 7Fr 指引导管的复杂 PCI 患者）。采用了多种分叉技术和钙化斑块修饰工具。主要终点为无血管入路交叉（0%）或术后 1 个月内主要不良心血管事件（0%）的手术成功率，次要终点为血管入路并发症发生率（1 例动脉痉挛[5%]）。
在我们的高危研究人群中，远端桡动脉入路联合 7Fr Railway 无鞘介入系统是一种可行且安全的复杂 PCI 入路选择。对于需要大口径指引导管的患者，这种方法可能是降低大出血事件或血管并发症风险的一种有价值的选择。
