ABSTRACT
Objective To explore the relative factors of unstable plaques of carotid atherosclerosis in ischemic eerebrovascular patients.Methods Carotid arteries of a total of 132 cases with ischemic cerebrovascular disease of carotid artery system were inspected by color Doppler ultrasound.The plaques discovered were classified according to ultrasonic appearance and their stability was judged.The relation between hypertension,diabetes,hyperlipemia, smoking and unstable plaques of carotid atheroselerosis was analyzed.Results The most common site of plaque for- mation was the bifurcate of the common carotid artery(56.99%),and the second commonest was carotid artery (23.12%).The incidence of unstable plaques in the patients with smoking,hypertension and diabetes was higher than those without them(P
