Conventional radial access has been shown to have many advantages over the transfemoral approach. The risk of potential radial artery occlusion and subsequent hand ischaemia can be reduced further by accessing the vessel distally at the anatomical snuffbox, allowing maintenance of antegrade flow to the hand by the superficial palmar arch branch. Additional potential advantages of distal radial access in comparison to the conventional radial approach at the wrist include fewer puncture-site complications and faster post-procedural haemostasis as the vessel is very superficial. Furthermore, it provides another safe, non-femoral option for vascular access. The use of ultrasound guidance enables the operator to identify important anatomical landmarks and avoid injuring adjacent structures. We provide a detailed step-by-step guide for performing distal radial access using sonographic and anatomical correlation, thereby facilitating safe access and optimising technical success.
传统的桡动脉入路相对于经股动脉入路具有许多优势。通过在解剖鼻烟窝处从远端进入血管，可以进一步降低潜在的桡动脉闭塞和随后手部缺血的风险，允许通过掌浅弓分支维持向手部的顺行血流。与手腕处的传统桡动脉入路相比，远端桡动脉入路的其他潜在优势包括穿刺部位并发症更少，术后止血更快，因为血管非常浅。此外，它为血管入路提供了另一种安全的非股动脉选择。超声引导的使用使操作者能够识别重要的解剖标志并避免损伤相邻结构。我们提供了使用超声和解剖相关性进行远端桡动脉入路的详细分步指南，从而促进安全进入并优化技术成功率。
