Goyal described occlusions in M2/3, A2/3 and P2/3 as medium vessel occlusions (MeVOs); the only available controlled data of mechanical thrombectomy (MT) in MeVOs is limited to the middle cerebral artery M2 segment, suggesting that MT may be effective and safe with high functional independence and recanalization rates. The Stent retriever Assisted Vacuum-locked Extraction (SAVE) technique in mechanical thrombectomy consists of the simultaneous use of a stent retriever and a distal aspiration catheter (DAC), with the removal of both as a unit when performing the thrombectomy pass; however, so far the low-profile (0.035 inch distal inner diameter) DACs were longer (160 cm) than conventional 0.017 inch microcatheters for MeVOs. We present a case of a combined approach MT in MeVO with the use of the new 167 cm long NeuroSlider 17 (Acandis, Pforzheim, Germany) 0.0165 inch microcatheter and 3MAX (Penumbra, Alameda, CA) through the SAVE technique-the MeVO SAVE technique.

戈亚尔将 M2/3、A2/3 和 P2/3 中的闭塞描述为中等大小血管闭塞 (MeVOs)；机械血栓切除术 (MT) 在 MeVOs 中唯一可用的对照数据仅限于大脑中动脉 M2 段，这表明 MT 可能具有较高的功能独立性和再通率，既有效又安全。机械血栓切除术中的支架取栓辅助抽吸锁闭提取 (SAVE) 技术包括同时使用支架取栓器和远端抽吸导管 (DAC)，在进行血栓切除时将两者作为一个整体取出；然而，迄今为止，用于 MeVOs 的低轮廓 (0.035 英寸远端内径) DAC 比传统的 0.017 英寸微导管更长 (160cm)。我们介绍了一例使用新的 167cm 长的 NeuroSlider 17（Acandis，普福尔茨海姆，德国）0.0165 英寸微导管和 3MAX（Penumbra，阿拉米达，CA）通过 SAVE 技术进行的 MeVO 联合 MT 治疗——MeVO SAVE 技术。(视频 1)。
