Abstract：Objective To investigate the value of ultrasonogram in detecting the stenosis of internal carotid artery initial segment in health examination.Methods In our hospital,360 cases were selected and compared.Results The positive rate of control group was 35.0％ (42/120)and that of ischemic cerebrovascular disease group was 90.8％ (218/240).The positive rate of ischemic cerebrovascular disease group was significantly higher than that of control group(P ＜ 0.05).The total stenosis rate of the internal carotid artery of control group was 33.3％ (40/120) and ischemic cerebrovascular disease group was 74.2％ (178/240).The total rate of ischemic cerebrovascular disease group was significantly higher than that of control group(P ＜ 0.05).The sensitivity of ultrasound was 87.7％ and specificity was 92.1％.Youden index was 0.80.Digital subtraction angiography(DSA) and ultrasound had no significant difference in diagnosis of mild,moderate stenosis and occlusion of the internal carotid artery (P ＞ 0.05).DSA and ultrasound had significant difference in diagnosis of severe stenosis carotid artery and atherosclerotic plaque (P ＜ 0.05).Conclusions Ultrasonography has high sensitivity and specificity.It can early show the stenosis of carotid artery and be used as the effective means in the health examination of asymptomatic population.
