Carotid endarterectomy (CEA) is one of the surgical treatment methods for the reconstruction of arterial stenosis or occlusion. Perioperative stroke, cerebral hemorrhage,hyperperfusion syndrome and death are main complications of CEA. Investigator have established a risk prediction model of the procedure based on vascular characteristics and hemodynamic parameters retrospectively. This prospective study was aimed to verify the predictive ability of CEA comprehensive prediction model through the analysis of patients receiving CEA procedure in the investigator's center in the next two years.
