Background and purpose

Aspiration is a successful technique used in thrombectomy for acute stroke. It is contingent upon the appropriate position of the aspiration catheter, so that it is in contact with the thrombus. However, navigating the craniocervical vasculature is challenging is some patients. The wedge microcatheter (MicroVention®) is designed to reduce the gap between the microcatheter and the SofiaPlus 6F catheter for ease of advancement. The purpose of this study is to describe our initial experience with the wedge microcatheter.

Materials and Methods

A retrospective review of 38 consecutive patients in whom the wedge microcatheter was used during thrombectomy was performed to determine whether the wedge microcatheter was successful in delivering the Sofia catheter to the desired location.

Results

We have found this device to be successful in delivering the aspiration catheter to the correct position in 97% (N = 37) of cases. It was used predominantly to pass the origin of branching vessels and also to navigate the tortuous cavernous and petrous segments of the ICA.

Conclusion

The wedge microcatheter is a successful tool in delivering the aspiration catheter to the desired vessel for revascularisation.

改善血管内进入目标血管以进行血栓抽吸——使用楔形装置克服解剖学障碍

背景和目的

抽吸是一项成功用于急性中风血栓切除术的技术。这取决于抽吸导管的适当位置，以便它与血栓接触。然而，导航颅颈血管系统对一些患者来说具有挑战性。楔形微导管 (MicroVention®) 旨在减小微导管与 SofiaPlus 6F 导管之间的间隙，以便于推进。本研究的目的是描述我们对楔形微导管的初步体验。

材料和方法

对 38 名在血栓切除术中使用楔形微导管的连续患者进行了回顾性研究，以确定楔形微导管是否成功地将 Sofia 导管输送到所需位置。

结果

我们发现该装置在 97% ( N  = 37) 的病例中成功地将抽吸导管输送到正确位置。它主要用于通过分支血管的起源，也用于导航 ICA 的曲折海绵体和岩石部分。

结论

楔形微导管是将抽吸导管输送到所需血管以进行血运重建的成功工具。
