Abstract

Goyal et al 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. (video 1).
