The transradial approach is routinely used for coronary angiography, but only limited data exist regarding transradial cerebral angiography. The purpose of this report was to offer detailed procedural methods for transradial cerebral angiography to facilitate adoption of the technique.
We reviewed 60 consecutive cases of transradial access used for neuroangiography and catalogued the indications for angiography, the sheath size, the catheter type, the length of the procedure, the number of cases in which radial artery access was unsuccessful, and the complications. We also noted procedural details regarding adjunctive medications, preprocedural patient assessment, and postprocedural care.
Transradial angiography was successfully applied in 57 of 60 cases (51 diagnostic, six interventional, three failed accesses). Sheaths were used in all cases and ranged in size from 4F to 6F. Mean procedural time for diagnostic cases was 40 minutes +/- 19 [SD]. Access-site complications included one forearm hematoma.
Transradial angiography is a useful tool for diagnostic and interventional neuroangiographic procedures. All relevant vessels can be accessed from the radial artery for diagnostic studies. Interventions in the right vertebral and carotid systems are facilitated by the transradial approach.
经桡动脉途径常用于冠状动脉造影，但关于经桡动脉脑血管造影的数据有限。本报告的目的是提供经桡动脉脑血管造影的详细操作方法，以促进该技术的应用。
我们回顾了连续60例用于神经血管造影的经桡动脉穿刺病例，并记录了血管造影的适应证、鞘管尺寸、导管类型、操作时间、桡动脉穿刺失败的病例数以及并发症。我们还记录了关于辅助用药、术前患者评估和术后护理的操作细节。
60例病例中有57例成功进行了经桡动脉血管造影（51例诊断性、6例介入性、3例穿刺失败）。所有病例均使用了鞘管，尺寸范围为4F至6F。诊断性病例的平均操作时间为40分钟±19[标准差]。穿刺部位并发症包括1例前臂血肿。
经桡动脉血管造影是诊断性和介入性神经血管造影操作的有用工具。在诊断性研究中，所有相关血管均可从桡动脉进入。经桡动脉途径便于对右侧椎动脉和颈动脉系统进行介入操作。
