Abstract

Background: Neurointervention via Transradial Access (TRA) is becoming increasingly popular as experience with this technique increases. However, approximately 8.6-10.3% of complex TRA cases are converted to femoral access due to a lack of support or radial artery spasm. This study aimed to assess the efficacy and safety of the TRUST (trans-radial coaxial catheter technique using a short sheath, Simmons catheter, and Tethys intermediate catheter) technique in interventional procedures via TRA.

Methods: This was a single-center retrospective analysis of 16 patients admitted to our institute between January 2023 to May 2023 to undergo endovascular interventions with the TRUST technique via the TRA.

Results: The mean age of the study population was 63.8 years, and 62.5% were male (10/16). The most common procedure was intracranial atherosclerotic stenosis (93.75%, 15/16). All procedures were performed successfully, and the most common procedures in our cohort were ballooning (50.0%, 8/16), stenting (18.75%, 3/16), and both procedures combined (31.25%, 1/16). All procedures were performed using the TRA, and the distal and proximal radial arteries were used for access in 31.35% (5/16) and 68.75% (11/16) of the cases, respectively. Technical success was achieved in all patients and most cases demonstrated mTICI ≥2b recanalization (93.75%, 15/16). In this case, no major access-site complications occurred.

Conclusion: The TRUST technique is technically safe and feasible and had a high technical success rate and low complication rate in our study. These results demonstrate that the TRUST technique is a promising alternative for patients undergoing complex neurointerventions.

神经干预 TRUST 技术:复杂病例的可行替代方案。
背景:随着经桡动脉入路(TRA)神经介入技术经验的增加,这种技术越来越受欢迎。然而,约有 8.6%-10.3% 的复杂 TRA 病例因缺乏支持或桡动脉痉挛而转为股动脉入路。本研究旨在评估 TRUST(使用短鞘、Simmons 导管和 Tethys 中间导管的经桡动脉同轴导管技术)技术在经 TRA 介入手术中的有效性和安全性:这是一项单中心回顾性分析,研究对象是2023年1月至2023年5月期间在我院住院,通过TRA使用TRUST技术进行血管内介入治疗的16名患者:研究对象的平均年龄为63.8岁,62.5%为男性(10/16)。最常见的手术是颅内动脉粥样硬化性狭窄(93.75%,15/16)。所有手术均成功实施,在我们的队列中,最常见的手术是球囊扩张术(50.0%,8/16)、支架植入术(18.75%,3/16)以及两种手术的合并(31.25%,1/16)。所有手术均使用 TRA,分别有 31.35% (5/16)和 68.75% (11/16)的病例使用桡动脉远端和近端入路。所有患者都取得了技术成功,大多数病例都显示出 mTICI ≥2b 的再通率(93.75%,15/16)。结论:TRUST 技术在技术上是安全的:结论:TRUST 技术在技术上安全可行,在我们的研究中技术成功率高,并发症发生率低。这些结果表明,对于接受复杂神经介入治疗的患者来说,TRUST 技术是一种很有前途的选择。
