Clinical Trial Summary

The purpose of this study is to explore the relationship between the recovery of cerebrovascular morphology and cognitive function before and after surgical treatment in patients with carotid artery stenosis and their preoperative cardiac health status. And combined with preoperative cognitive status, serum markers, and cardiovascular health evaluation indicators, evaluate and predict the possibility of postoperative neurodegenerative diseases and the level of cerebrovascular health in patients.


Clinical Trial Description

The aim of this study is to evaluate the brain health status and surgical efficacy of patients with carotid artery stenosis. Firstly, investigate whether hemodynamic parameters such as blood flow reserve fraction at the carotid artery stenosis site are correlated with white matter hyperintensities and cerebral vascular morphological changes in elderly patients with normal cognition and mild cognitive impairment; Then, when the blood flow of carotid artery has been improved after surgery, compare the cerebrovascular health of patients before surgery and the way of cerebral vascular reconstruction; Combined with the postoperative neuropsychological cognitive test to explore the postoperative cognitive recovery of patients, and combined with the postoperative imaging data and the biomarker in the blood of patients at various stages, to explore the way of cerebral vascular reconstruction and changes in brain structure and function of different groups of patients behind cognitive changes. ;
