M2 occlusions represent 16%-41% of all middle cerebral artery occlusions, with >50% of functional independence achieved. The American Heart Association/American Stroke Association 2018 guidelines suggest that, with a level of evidence B-R, thrombectomy with stent retrievers may be appropriate for selected patients with M2 or M3 occlusions. The purpose of this study is to illustrate a new technique of distal (M2-M3) thrombectomy.
Eight patients from May 2018 to February 2019 underwent a thrombectomy procedure for a M2 or M3 occlusion with a 3MAX or 4MAX intermediate aspiration catheter, a Headway Duo 167 cm microcatheter, and a Catchview Mini stent retriever.
All thrombectomies were technically successful, defined as thrombolysis in cerebral infarction score ≤2b. Five out of the 8 patients attained a good functional outcome at 3 months, defined as modified Rankin scale score ≤2.
This technique allows a safe and effective distal thrombectomy for M2-M3 occlusions.
M2 闭塞占所有大脑中动脉闭塞的 16%-41%，其中>50%的患者可实现功能独立。美国心脏协会/美国中风协会 2018 指南建议，在证据水平为 B-R 的情况下，支架取栓术可能适用于某些 M2 或 M3 闭塞的患者。本研究旨在介绍一种新的远端（M2-M3）血栓切除术技术。
2018 年 5 月至 2019 年 2 月，8 名患者接受了 M2 或 M3 闭塞的血栓切除术，使用 3MAX 或 4MAX 中间抽吸导管、Headway Duo 167cm 微导管和 Catchview Mini 支架取栓器。
所有血栓切除术均技术上成功，定义为脑梗死溶栓评分≤2b。8 名患者中有 5 名在 3 个月时获得了良好的功能结局，定义为改良 Rankin 量表评分≤2。
该技术可安全有效地进行 M2-M3 闭塞的远端血栓切除术。
