Abstract

Purpose: The transradial artery approach (TRA) has recently gained popularity in neuroendovascular procedures with its advantages of the fewer complications and reduced invasiveness. However, forearm radial artery (RA) tortuosity has led to procedural failure in some cases. Therefore, this study aimed to investigate the influence of forearm RA tortuosity on TRA failure and evaluate its association with patients' characteristics and the procedure-related factors.

Methods: We retrospectively examined the characteristics of 239 patients who underwent neuroendovascular procedures at our facility between January 2023 and November 2024.

Results: Among the 239 patients, 28 exhibited forearm RA tortuosity, and switching from TRA was significantly more frequent among these patients (64.3% vs. 5.2%, p < 0.01). Additionally, they were significantly older (74.8 vs. 60.6 [years], p < 0.01), shorter in stature (1.55 vs. 1.62 [m], p < 0.01), and lighter in body weight (53.0 vs. 60.0 [kg], p < 0.01). Moreover, they were complicated with dyslipidemia (57.1% vs. 36.5%, p = 0.04). The cut-off values associated with an increased risk of forearm RA tortuosity were age > 71 years (p < 0.0001), height < 1.60 m for men (p = 0.0365), and height < 1.55 m for women (p = 0.0010).

Conclusion: Forearm RA tortuosity significantly influenced the choice of neuroendovasucular approach and was significantly correlated with the age and physique of patients. Pre-procedural evaluation of the forearm RA course is crucial in TRA, and preparation for switching the approach from TRA was hoped in high-risk cases.

前臂桡动脉弯曲的注意事项：经桡骨神经血管内手术失败的风险。

目的：经桡动脉入路（TRA）近年来在神经血管内手术中越来越受欢迎，其优点是并发症少，侵入性小。然而，前臂桡动脉（RA）弯曲在某些情况下导致手术失败。因此，本研究旨在探讨前臂RA弯曲对TRA失败的影响，并评估其与患者特征和手术相关因素的关系。方法：我们回顾性分析了2023年1月至2024年11月期间在我们医院接受神经血管内手术的239例患者的特征。结果：239例患者中，有28例患者表现为前臂RA弯曲，这些患者中从TRA转路的频率明显更高（64.3% vs. 5.2%， p  71岁）（p ）结论：前臂RA弯曲显著影响神经血管内入路的选择，并与患者的年龄和体质显著相关。前臂RA病程的术前评估在TRA中至关重要，希望在高危病例中为从TRA转换入路做好准备。
