Intervention strategies for symptomatic middle cerebral atherosclerotic stenosis

Intracranial atherosclerotic stenosis (ICAS) is the most common cause of ischemic stroke among Asian population, and its predilection site is middle cerebral artery. Symptomatic middle cerebral atherosclerotic stenosis (sMCAS) has a high risk of stroke recurrence and needs active interventions, but the choice of intervention strategy is controversial. This article reviews the pathogenesis, clinical manifestations, imaging evaluation and intervention strategies of sMCAS, aiming to provide reference for individual selection of intervention strategies.
