BackgroundGuiding catheters (GCs) are crucial platforms for neuroendovascular procedures. High-support pre-shaped guiding catheters (HPGCs) were designed to address access difficulties in complex anatomies. Given its versatility in neuroendovascular treatment, we report our single-center experience with the HPGCs.MethodsA single-center retrospective analysis was conducted on 154 neuroendovascular procedures using the HPGCs between January 2017 and February 2024. The HPGCs include three models: SEL-E, IWATE, and IWATE-L. The cases were categorized into three scenarios: addressing access failure, serving as a platform for posterior circulation interventions, and supporting angioplasty for neck-thoracic lesions. Data on procedural success, complications, and anatomical characteristics were collected.ResultsSuccessful access was achieved in 92.4% of access failure cases (n = 79). Successful recanalization was achieved in 60.5% of thrombectomy cases, with a median patient age of 89 years and complex vascular anatomies involving a type 3 aorta in 94.2% of cases. For posterior circulation procedures (n = 67), the treatment success rate was 97.0%, utilizing a strategy that combined the HPGCs with intermediate catheters to prevent large-bore GCs from entering the vertebral artery. In angioplasty for neck-thoracic lesions (n = 8), technical success was achieved in 75% of patients.ConclusionsThe pre-shaped, high-support features of the HPGCs demonstrated effectiveness and safety in access failure cases while enabling broader utilization in posterior circulation and neck-thoracic lesion procedures.
背景
引导导管(GCs)是神经血管内介入手术的关键平台。高支撑预塑形引导导管(HPGCs)旨在解决复杂解剖结构中的通路困难问题。鉴于其在神经血管内治疗中的多功能性,我们报告我们单中心使用HPGCs的经验。
方法
对2017年1月至2024年2月期间使用HPGCs进行的154例神经血管内介入手术进行单中心回顾性分析。HPGCs包括三种型号:SEL-E、岩手型和岩手-L型。病例分为三种情况:解决通路失败、作为后循环介入的平台以及支持颈部-胸部病变的血管成形术。收集手术成功率、并发症和解剖特征的数据。
结果
在92.4%的通路失败病例(n = 79)中成功实现了通路建立。在60.5%的取栓病例中成功实现了再通,患者中位年龄为89岁,94.2%的病例存在复杂血管解剖结构,包括3型主动脉。对于后循环手术(n = 67),治疗成功率为97.0%,采用了将HPGCs与中间导管相结合的策略,以防止大口径GCs进入椎动脉。在颈部-胸部病变的血管成形术(n = 8)中,75%的患者取得了技术成功。
结论
HPGCs的预塑形、高支撑特性在通路失败病例中显示出有效性和安全性,同时在后循环和颈部-胸部病变手术中具有更广泛的应用。
