Abstract：
BACKGROUND: Radial arterial access has gained interest for neurovascular procedures in recent years. Although there are no randomized control trials for neurointervention procedures using radial access, there is growing literature demonstrating its feasibility and favorable outcomes. Equipment technical improvements, like the recently introduced BENCHMARK™ BMX®81 System, have made radial navigation safer, with improved maneuverability and support for a variety of procedures. We present a multicenter case series highlighting our institutional radial access experience comparing the BMX®81 with alternative catheters.
METHODS: Multicenter retrospective cohort study of 80 patients who underwent neurovascular procedures through a radial approach. In half of the cases a BENCHMARK™ BMX®81 System was used. The comparison group consisted of the BENCHMARK™071 and 96, Neuron MAX®088 and BALLAST™ systems. Procedures included endovascular thrombectomy, carotid and brachiocephalic artery stenting, middle meningeal artery embolization, flow diverter stenting, vertebral artery sacrifice, aneurysm coiling, and WEB™ device deployment.
RESULTS: In our series, the BMX®81 was successful in the navigation of the anatomy to the target location in 95% of cases. No radial access or BMX®81 related complications were identified. There was no significant difference in fluoroscopy time between the BMX81 and the comparison group. Four patients in the comparison group had catheter-related complications due to vasospasm. Eighty-six percent of BMX®81 cases had satisfactory outcomes and no technical difficulties. The remainder presented technical difficulties, but none of these were considered secondary to the puncture site or support structure.
CONCLUSIONS: The BENCHMARK™ BMX®81 System is a recently developed guiding catheter which has design and size features supporting radial access for a variety of neurovascular interventions. Early multicenter experience highlights the ease of use and versatility of this new catheter as an alternative to transfemoral access as well as other catheters used for radial access.

摘要：
背景：近年来，桡动脉通路已引起神经血管手术的兴趣。虽然没有使用放射状通路进行神经干预的随机对照试验，越来越多的文献证明了它的可行性和有利的结果。设备技术改进，像最近推出的BENCHMARK™BMX®81系统一样，使径向导航更安全，具有改进的可操作性和对各种程序的支持。我们提供了一个多中心病例系列，重点介绍了我们的机构径向接入经验，将BMX®81与替代导管进行了比较。
方法：多中心回顾性队列研究，对80例通过放射状入路进行神经血管手术的患者进行研究。在一半的病例中使用了BENCHMARK™BMX®81系统。对照组由BENCHMARK™071和96、NeuronMAX®088和BALLAST™系统组成。手术包括血管内血栓切除术，颈动脉和头臂动脉支架置入术,脑膜中动脉栓塞,导流器支架,椎动脉牺牲,动脉瘤卷绕，和WEB™设备部署。
结果：在我们的系列中，在95%的病例中,BMX®81成功地将解剖结构导航至目标位置.未发现放射状入路或BMX®81相关并发症。BMX81与对比组的透视时光差别无统计学意义。对照组中有4例患者因血管痉挛而出现导管相关并发症。86％的BMX®81例获得了令人满意的结果，没有技术困难。其余的提出了技术上的困难，但这些都不被认为是继发于穿刺部位或支撑结构。
结论：BENCHMARK™BMX®81系统是最近开发的一种引导导管，其设计和尺寸特征支持多种神经血管介入的放射状通路。早期的多中心经验强调了这种新导管的易用性和多功能性，可替代经股动脉入路以及用于放射状入路的其他导管。
