脑梗塞患者颈动脉粥样硬化的彩色多普勒超声检测

Detection of Carotid Atherosclerosis in patients with Cerebral Infarction by Color Doppler Ultrasound

本文应用彩色多普勒超声诊断仪,对83例脑梗塞患者的颈动脉进行了检测分析,粥样硬化斑块的检测率为55.6%,以硬斑为主,主要分布在颈总动脉分叉处,脑梗塞患者的斑块积分明显高于对照组(P〈0.01),斑块与脑梗塞灶的侧向符合率为87.2%.脑梗塞患者梗塞侧的血管内径,内膜至中膜厚度,收缩期峰值流速,血管搏动指数,血管阻力指数与对照组比较均有显著差异(P<0.05).认为上述各项参数结合彩色多普勒在血管腔内的显示情况可作为综合判断脑梗塞患者颈动脉粥样硬化的客观指标.

In this study, the carotid arteries of 83 pafients with cere bral infaction were assessed by Color Dopller ultrasounography. The resultsrevealed that the atherosclerotic plagues were detected in 55.6% patients, most of these plagues were hard and located in BIF. THe plague scores of patients with cerebral infarction were significantly higher than those of controls (P<0.01) . In 87.2% patientsthe site of plagues and infarct lesions was ipsilateral. The caliber IMT, Vmax, PI and RI of patients was different significantly from controls (P<0.05) . We conclud that Color Doppler ultrasound can be used for detecting carotid atherosclerotic lesions in patients with cerebral infarction.
