Percutaneous revascularization of superficial femoral artery (SFA) is increasingly carried out to treat patients with peripheral vascular disease and either intermittent claudication or critical limb ischemia. Transradial vascular access is increasingly adopted for invasive procedures due to reduced access-site complications and improved patient's comfort, compared with transfemoral. However, compared with coronary interventions, the adoption of transradial access in peripheral procedures is limited. Concerning SFA interventions, transradial access is usually prevented by the distance between the vascular access and the target lesion, which extends over the length of the currently available devices. Thanks to technical improvements, resulting in specifically dedicated low-profile equipment with adequate shaft length availability, transradial access is now feasible for the treatment of selected SFA lesions. We report the first two cases of SFA stenting performed by transradial access with a new specifically developed self-expanding nitinol stent with extended delivery system length. This report suggests that, with proper technique and specifically dedicated equipment, transradial SFA stenting is feasible. Treatment of SFA disease by transradial route, allowing for immediate post-procedure walking and simultaneous bilateral interventions, may represent an alternative for effective treatment of selected patients with SFA lesions.
经皮股浅动脉（SFA）血运重建术越来越多地用于治疗外周血管疾病患者，这些患者有间歇性跛行或严重肢体缺血。与经股相比，由于减少了入路并发症和提高了患者的舒适度，经桡动脉血管入路越来越多地应用于介入性操作。然而，与冠状动脉介入治疗相比，经桡动脉入路在外周介入治疗中的应用受到限制。对于 SFA 介入治疗，由于血管入路和目标病变之间的距离较长，目前可用的器械长度不足以到达病变部位，通常会阻止经桡动脉入路。得益于技术的改进，现在可以使用专门设计的、具有足够轴长的专用低轮廓设备，使经桡动脉入路治疗特定的 SFA 病变成为可能。我们报告了首例使用新型专用自膨式镍钛诺支架和延长输送系统长度进行经桡动脉 SFA 支架置入术的两例病例。本报告表明，通过适当的技术和专用设备，经桡动脉 SFA 支架置入术是可行的。经桡动脉入路治疗 SFA 疾病，可在术后立即行走，并同时进行双侧介入治疗，可能为治疗特定的 SFA 病变患者提供一种有效的替代方法。
