Recent advance in correlation between imaging evaluation before endovascular treatment of acute basilar artery occlusion and clinical prognoses

Abstract

Acute basilar artery occlusion (ABAO) has a high rate of disability and mortality, and the key to its treatment is to start reperfusion therapy as early as possible. A number of retrospective studies have found that the good prognosis rate of endovascular treatment of ABAO is related to number of infarction locus, extent of ABAO, vascular occlusion and collateral circulation. Screening patients through imaging evaluation before endovascular treatment may further improve the rate of favorable outcome. This article reviews research progress on the correlation between imaging evaluation before endovascular treatment of ABAO and clinical prognoses. Key words: Basilar artery occlusion; Endovascular treatment; Imaging evaluation; Prognoses
