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, with the removal of both as a unit when performing the thrombectomy pass. This is a safe procedure that provides a high rate of first-pass reperfusion.1 In the distal M1 segment of the middle cerebral artery (MCA) occlusions, with the distal portion of the clot extending to the upper and lower MCA branches, mechanical thrombectomy can be challenging since the thrombus is not fully trapped, with risk of distal clot migration to the branch in which the retriever is not placed. In these cases the double stent-retriever technique has been described as a rescue strategy.2-4 We describe a case of the combined use of SAVE and double stent-retriever techniques as a rescue strategy in a patient with tandem occlusion of the proximal internal carotid artery and distal MCA-the D-SAVE technique.

在机械取栓中，支架取栓辅助抽吸锁闭（SAVE）技术包括同时使用支架取栓器和远端抽吸导管，在进行取栓操作时，两者作为一个整体一起取出。这是一种安全的操作方法，可提供高的初次通过再灌注率。1 在大脑中动脉（MCA）M1 段的远端闭塞中，由于血栓的远端部分延伸至 MCA 上、下分支，机械取栓可能具有挑战性，因为血栓不能被完全捕获，存在血栓向取栓器未放置的分支迁移的风险。在这些情况下，已经描述了双支架取栓技术作为一种挽救策略。2-4 我们描述了一种在近端颈内动脉和远端 MCA 串联闭塞患者中联合使用 SAVE 和双支架取栓技术作为挽救策略的情况，即 D-SAVE 技术（视频 1）。
