Radial artery occlusion (RAO) is the most common structural consequence of transradial access (TRA) with an estimated incidence ranging from 2-10 %. Its occurrence is free of any major clinical consequences, especially at rest, with most if not all cases of digital ischemia occurring as a result of embolization, rather than RAO. The incidence of RAO is unacceptably high if "best practices" are not followed. Strategies to prevent RAO need to be implemented to preserve radial artery patency in order to exploit other benefits of TRA.
桡动脉闭塞（RAO）是经桡动脉入路（TRA）最常见的结构后果，其发生率估计为 2-10%。其发生没有任何重大临床后果，尤其是在休息时，大多数（如果不是全部）手指缺血的情况是由于栓塞而不是 RAO 引起的。如果不遵循“最佳实践”，RAO 的发生率是不可接受的。需要实施预防 RAO 的策略来保持桡动脉通畅，以利用 TRA 的其他益处。
