Purpose

To demonstrate that left radial access for diagnostic cerebral angiography with Extra backup and 4F vertebral catheters is feasible and safe.

Materials and methods

This study is a retrospective review of our prospective database on left radial access for cerebral angiography procedures, using an extra backup catheter associated with a 4Fr vertebral catheter, performed between March and September 2019. Patient demographics, procedural and radiographic metrics as well as clinical data were recorded.

Results

Seventy five patients with mean age of 51...years (range 21...73) underwent 80 cerebral angiographies. An average of four vessels were catheterized and mean fluoroscopy times per subject and vessel were was of 13.9 and 3.3...min, respectively. One patient required crossover to transfemoral access because of radial artery spasm. There were one asymptomatic distal radial artery occlusion and one patient presenting with asymptomatic skin blanching area on the forearm, just proximal to the tip of the sheath, that spontaneously resolved within an hour.

Conclusion

Diagnostic cerebral angiography via left radial access is feasible and safe and allows to preserve the right radial access for future neurointerventions while providing more comfort to the right handed patient.

一项通过左侧桡动脉入路进行脑血管造影的新技术：80 例患者系列

目的

证明使用 Extra backup 和 4F 椎体导管进行诊断性脑血管造影的左桡动脉通路是可行且安全的。

材料和方法

本研究是对我们在 2019 年 3 月至 2019 年 9 月期间使用与 4Fr 椎体导管相关的额外备用导管进行脑血管造影手术的左桡动脉入路前瞻性数据库的回顾性研究。患者人口统计学、程序和影像学指标以及临床数据被记录下来。

结果

75 名平均年龄为 51...岁（范围 21...73）的患者接受了 80 次脑血管造影。平均有四个血管插入导管，每个受试者和血管的平均透视时间分别为 13.9 和 3.3...min。由于桡动脉痉挛，一名患者需要交叉经股动脉入路。有一名无症状的桡动脉远端闭塞，一名患者在前臂上出现无症状的皮肤变白区域，就在鞘尖端的近端，在一小时内自发消退。

结论

通过左侧桡动脉通路进行的诊断性脑血管造影是可行且安全的，并且可以保留右侧桡动脉通路用于未来的神经干预，同时为右利手患者提供更多舒适度。
