Endovascular treatment with mSAVE.
A, CT-angiography (coronal view) of a patient suffering from a distal occlusion of the internal carotid artery (ICA) on the left site. B, First angiogram demonstrating extracranial pseudo-occlusion of the ICA. C, Positioning of a stent retriever in the distal ICA and proximal M1 segment with antegrade flow via the deployed stent retriever. D, The aspiration catheter is connected to an activated pump and advanced to the proximal face of the clot until vacuum is achieved. E, The aspiration catheter is then retrieved along the wire of the stent retriever without moving the stent retriever itself in order to reduce thrombus mass and subsequently advanced to the occlusion site after vacuum is lost. F, The pump canister is showing massive amount of clot prior to embolectomy. G, After performing one attempt of SAVE maneuver the intracranial lesion is recanalized and the downstream territory completely reperfused. H, Final computed tomography at discharge demonstrating a small infarction within the basal ganglia.
