研究目的:

评价慢性脑血流灌注不足对类淋巴系统功能及脑内Aβ沉积的影响,并于患者行颈动脉支架成形术改善脑血流灌注后3个月,再次观察改善脑血流灌注对Aβ沉积及类淋巴系统功能的影响。  

Objectives of Study:

We aim to measure cerebral amyloid-β(Aβ) deposition and glymphatic system function in patients with severe unilateral carotid artery stenosis at baseline and 3 months after carotid angioplasty and stenting to evaluate the effects of chronic cerebral perfusion insufficiency on Aβ deposition in the brain and its relationship with glymphatic system.
