高频超声检测颈动脉早期诊断颅内颈内动脉系统远端阻塞性病变

目的：利用高频超声检测颈动脉早期诊断颅内颈内动脉系统远端阻塞性病变。方法：对三组（正常组、无脑梗死颈动脉粥样硬化组、脑梗死颈动脉粥样硬化组）共120例患者行超声检查颈动脉，观察动脉硬化情况，记录血流值。对三组同侧颈内动脉与颈总动脉血流收缩期血流速度比值（ICA／CCA）进行统计学F检验。结果：正常组、无脑梗死颈动脉粥样硬化组与脑梗死颈动脉粥样硬化组的IcA／CCA比值有统计学显著差异（P〈0．05），正常组与无脑梗死颈动脉粥样硬化组的ICA／CCA比值无统计学显著差异（P〉0．05）。结论：同侧颈内动脉与颈总动脉血流收缩期血流速度比值（ICA／CCA）有助于早期诊断颅内颈内动脉系统远端阻塞性病变。

Measurement of carotid flow parameters by high frequency to diagnose distant blockage in internal carotid artery ultrasound

Objective To diagnose distant blockage in internal carotid artery using high frequency ultrasound survey carotid.Methods B-mode and color Doppler ultrasound were used to examine 120 persons who were subdivided into three groups(healthy,carotid atherosclerosis without cerebral infarction,and carotid atherosclerosis with cerebral infarction.) Results The numeral internal carotid/common carotid was significantly higher than that in healthy and carotid atherosclerosis without cerebral infarction groups(P<0.05).The ratio of numeral internal carotid to common carotid wasn't significantly different between that in healthy group and carotid atherosclerosis without cerebral infarction group(P>0.05).Conclusion The numeral internal carotid/common carotid can promote diagnosis distant blockage in internal carotid artery early.
