A review of endovascular treatment for medium vessel occlusion stroke

Medium-vessel occlusions (MeVOs), that is, of the M2/3 middle cerebral artery, A2/3 anterior and P2/3 posterior artery segments, account for 25%–40% all acute ischemic stroke cases. Clinical outcomes MeVO with intravenous thrombolysis, which is current standard care, are moderate at best. With improving imaging technologies a growing literature, MeVOs increasingly recognized as target endovascular treatment (EVT). For time being, there limited but promising evidence safety efficacy EVT, many neurointerventionists already routinely offering EVT stroke, despite lack clear guideline recommendations. In this article, we review on summarize available literature strategies, commonly used selection criteria, techniques, outcome assessment stroke.
