Stent Retriever Angioplasty for Intracranial Atherosclerotic Disease-Related Medium Vessel Occlusion: A Case Report and Literature Review.

Objective: Stent retriever (SR) angioplasty is an adjunctive technique for acute large vessel occlusion stroke due to underlying intracranial atherosclerotic disease (ICAD-LVO). Prolonged SR deployment maintains blood flow distal to the atherosclerotic lesion until the antiplatelet agent has exerted its effect. Although SR angioplasty for ICAD-LVO has been reported, few reports are available on SR angioplasty for medium vessel occlusion stroke due to underlying ICAD (ICAD-MeVO).
