“…Durable patency of the carotid artery may prevent recurrent intracranial embolisms, hemodynamic insufficiency (resulting in the expansion of the ischemic cerebral territory), carotid artery restenosis or reocclusion, and the shedding of unstable plaque. 4,38,39 In addition, considering that reperfusion is an important predictor of functional outcomes in TLs, 1,40 it has been suggested that the advantage of acute CAS is most likely related to the augmentation of intracranial perfusion. 41 In our analysis, we examined acute CAS as the exposure and used successful reperfusion as the mediating factor.…”
