Aims Trans-radial access (TRA) is the recommended approach for coronary angiography and percutaneous coronary intervention (PCI). Radial artery occlusion (RAO) is the most common complication. We examined the incidence of RAO by means of duplex ultrasonography (DUSG) and the reverse Barbeau test (RBT), after TRA in a clinical setting using conventional compression dressings to achieve haemostasis. All radial artery patency examinations were performed by one dedicated nurse after a brief training course, we assessed the feasibility and quality of this routine in regular clinical practice. Methods and results In total 97 patients undergoing first time coronary angiograph and in some cases PCI via TRA completed the study. Conventional pressure dressing as means of haemostasis was used. Radial artery patency was examined by DUSG and by RBT, before and at follow-up one month after the procedure. An inter- and intra-observer validation of the ultrasound measurements was performed prior to inclusion. Two cases of RAO (2.1%) were discovered following TRA. All RAO cases were detected by both DUSG and the RBT. Results from the inter-observer validation showed no statistically significant discrepancy between an experienced physician and a newly trained nurse operator (p = 0.403). An intraclass correlation coefficient (ICC) was calculated at 0.89 indicating excellent reproducibility. Conclusion In a high-volume TRA centre, we detected an overall low incidence of RAO using conventional pressure dressing as means of haemostasis. The easy-to-use RBT detected all cases of RAO. Following a short course of training, a nurse from the cardiac catheterisation laboratory was able to perform high quality DUSG examinations of the radial artery to assess patency.

经桡动脉冠状动脉造影后的桡动脉闭塞 一项由护士主导的研究，采用双重超声检查和反向巴博试验。

目的 经桡动脉入路 (TRA) 是冠状动脉造影和经皮冠状动脉介入治疗 (PCI) 的推荐方法。桡动脉闭塞（RAO）是最常见的并发症。我们在临床环境中使用常规压迫敷料实现 TRA 止血后，通过双功能超声检查 (DUSG) 和反向 Barbeau 试验 (RBT) 检查了 RAO 的发生率。所有桡动脉通畅检查均由一名专职护士在经过简短的培训课程后进行，我们在常规临床实践中评估了该常规的可行性和质量。方法和结果 共有 97 名接受首次冠状动脉造影的患者完成了研究，在某些情况下还通过 TRA 接受了 PCI。使用常规压力敷料作为止血手段。在手术前和手术后一个月的随访中，通过 DUSG 和 RBT 检查桡动脉通畅情况。在纳入之前，对超声测量结果进行了观察者间和观察者内的验证。TRA 后发现两例 RAO (2.1%)。所有 RAO 病例均由 DUSG 和 RBT 检测到。观察者间验证的结果显示，经验丰富的医生和新培训的护士操作员之间没有统计学上的显着差异（p = 0.403）。计算得出的组内相关系数 (ICC) 为 0.89，表明具有极好的重现性。结论 在一个大容量的 TRA 中心，我们发现使用传统压力敷料作为止血手段时 RAO 的发生率总体较低。易于使用的 RBT 可以检测到所有 RAO 病例。经过短期培训后，心导管实验室的一名护士能够对桡动脉进行高质量的 DUSG 检查，以评估通畅性。
