Cerebral Embolic Damage
Conditions
Brief summary
1. In carotid endarterectomy(CEA) surgery, the dynamic changes of plasma MMP9 concentration cross CEA will be identified. 2. And the part of patients suffered particulate cerebral embolic injury, their MMP9 level will increase in the early stage after CEA.
