This study evaluated the feasibility and efficacy of the Trans-Radial telescoping catheter technique using a Distal Access catheter and Simmons catheter (RDAS) compared to the traditional Catheter Exchange Technique (CET) in neurointerventional procedures via the transradial approach (TRA). A retrospective analysis was performed for 149 consecutive patients undergoing neurointerventions via TRA in 2 dedicated neurointerventional centers, using either RDAS (n = 124) or CET (n = 25). Key endpoints included technical success rate, procedural time, and fluoroscopy time. RDAS demonstrated a 100% technical success rate, compared to 88% in the CET group. Mean procedural time taken (RDAS 13.4 min [range = 6.1-23.7] versus CET 19.3 min [range = 8.7-45.7]; p = 0.003) and fluoroscopy time length (RDAS 8.1 min [range = 3.9-16.5] versus CET 10.6 min [range = 6.2-23.6]; p = 0.024) were significantly lower in RDAS than in CET. RDAS consistently allowed placement of the guiding catheter into the petrous ICA or beyond in 94.4% of cases. No procedure-related complications were observed. Compared to CET, RDAS technique allows improved efficacy and time-efficiency in neurointerventional procedures via TRA. Clinical trial number Not applicable.
本研究评估了在经桡动脉途径（TRA）的神经介入手术中，与传统导管交换技术（CET）相比，使用远端通路导管和西蒙斯导管（RDAS）的经桡可伸缩导管技术的可行性和有效性。对在2个专门的神经介入中心通过TRA进行神经介入治疗的149例连续患者进行了回顾性分析，其中使用RDAS的患者有124例，使用CET的患者有25例。主要终点包括技术成功率、手术时间和透视时间。RDAS的技术成功率为100%，而CET组为88%。平均手术时间（RDAS为13.4分钟[范围=6.1 - 23.7]，CET为19.3分钟[范围=8.7 - 45.7]；p = 0.003）和透视时间长度（RDAS为8.1分钟[范围=3.9 - 16.5]，CET为10.6分钟[范围=6.2 - 23.6]；p = 0.024），RDAS均显著低于CET。RDAS在94.4%的病例中始终能够将引导导管放置到岩骨段颈内动脉或更远端。未观察到与手术相关的并发症。与CET相比，RDAS技术在经TRA的神经介入手术中能提高疗效和时间效率。临床试验编号不适用。
