Background

While Balloon Guide Catheters (BGC) have been shown to increase the rate of reperfusion during mechanical thrombectomy (MT), its implementation with transfemoral approach is at times limited due to unfavorable vascular anatomy.

Objective

to determine safety, feasibility and performance of the transradial use of 8 F BGC Flowgate2 during mechanical thrombectomy procedures in patients with unfavorable vascular anatomies (type 3 or bovine arch)

Material/Methods: We performed a retrospective cohort study of consecutive transradial mechanical thrombectomies performed with BGC Flowgate2 between January and December 2019. Patient demographics, procedural and radiographic metrics, and clinical data were analyzed.

Results

20 (8.7%) out of 230 overall thrombectomy procedures underwent transradial approach using an 8 F BGC Flowgate.2 Successful approach was achieved in 17/20 cases, and in 3 cases radial was switched to femoral, after failure. TICI 2 C/3 was achieved in 18 cases (90%), followed by TICI 2 b and 2a in 1 (5%) case respectively. The average number of passes was 1.8. The average radial puncture-to-first pass time was 22 min. Radial vasospasm was observed in 3/20 cases. The Flowgate2 was found kinked in 4/20 cases (20%), all of them during right internal carotid procedures. There were no postprocedural complications at puncture site, as hematoma, pseudoaneurysm or local ischemic events

Conclusion

The use of 8 F Balloon Guide Catheter during MT via transradial approach might represent an alternative in selected cases with unfavorable vascular anatomies. Its use in right ICA catheterizations was associated with a high rate of catheter kinking.

经桡动脉使用 8F 球囊引导导管 Flowgate2 用于急性缺血性卒中血管内血栓切除术的安全性和可行性

背景

虽然球囊引导导管 (BGC) 已被证明可增加机械血栓切除术 (MT) 期间的再灌注率,但由于不利的血管解剖结构,其在经股动脉入路的实施有时受到限制。

客观的

确定在血管解剖不良(3 型或牛弓)患者的机械血栓切除术中经桡动脉使用 8 F BGC Flowgate 2的安全性、可行性和性能

材料/方法:我们对 2019 年 1 月至 2019 年 12 月期间使用 BGC Flowgate 2进行的连续经桡动脉机械血栓切除术进行了一项回顾性队列研究。分析了患者人口统计学、程序和影像学指标以及临床数据。

结果

230 例血栓切除术中的 20 例 (8.7%) 采用 8 F BGC Flowgate 经桡动脉入路。2成功入路 17/20 例,失败后 3 例桡骨转股骨。TICI 2 C/3 达到 18 例(90%),其次分别是 TICI 2 b 和 2a 1 例(5%)。平均通过次数为 1.8。平均径向穿刺到第一次通过时间为 22 分钟。3/20 例出现桡动脉痉挛。Flowgate 2在 4/20 例 (20%) 中被发现扭结,所有病例均在右侧颈内动脉手术期间发生。穿刺部位没有术后并发症,如血肿、假性动脉瘤或局部缺血事件

结论

在 MT 期间通过经桡动脉途径使用 8 F 球囊引导导管可能是在血管解剖不利的选定病例中的替代方案。它在右 ICA 导管插入术中的使用与导管扭结率高有关。
