背景:随着使用这种技术的经验的增加,通过经radial骨通路(TRA)进行的神经干预变得越来越流行。然而,由于缺乏支持或桡动脉痉挛,大约8.6-10.3%的复杂TRA病例被转换为股骨入路。本研究旨在评估TRUST(使用短鞘的经径向同轴导管技术,Simmons导管,和Tethys中间导管)技术在通过TRA进行的介入手术中。
方法:这是一项单中心回顾性分析,分析了2023年1月至2023年5月在我们研究所接受TRUST技术通过TRA进行血管内干预的16例患者。
结果:研究人群的平均年龄为63.8岁,男性占62.5%(10/16)。最常见的手术是颅内动脉粥样硬化狭窄(93.75%,15/16)。所有程序都成功执行,我们队列中最常见的手术是膨胀(50.0%,8/16),支架(18.75%,3/16),和两个程序相结合(31.25%,1/16)。所有程序均使用TRA进行,31.35%(5/16)和68.75%(11/16)的病例采用远端和近端桡动脉入路,分别。所有患者均取得了技术成功,大多数病例显示mTICI≥2b再通(93.75%,15/16)。在这种情况下,没有发生主要的通路部位并发症.
结论:在我们的研究中,TRUST技术技术安全可行,技术成功率高,并发症发生率低。这些结果表明,TRUST技术对于接受复杂神经干预的患者是一种有前途的替代方法。
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.
CONCLUSIONS: 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.
