彩色多普勒超声对脑梗死颈动脉粥样硬化斑块的诊断价值

Diagnostic Value of Color Doppler Ultrasound for Carotid Atherosclerotic Plaque of Cerebral Infarction

目的探讨彩色多普勒超声对脑梗死颈动脉粥样硬化斑块的诊断价值。方法选取2021年5月—2023年9月本院收治的脑梗死患者50例设为观察组;选取同期的健康体检者50例设为对照组。两组均予彩色多普勒超声检查,比较两组动脉增厚及斑块形成情况,分析斑块类型及血管狭窄程度,对比两组颈动脉血流指标。结果观察组颈动脉内-中膜增厚率、斑块形成率、多发斑块率均高于对照组(P<0.05)。两组斑块多集中于颈动脉分叉处,观察组此处斑块占比为55.81%,对照组占比为52.38%(P>0.05)。观察组软斑、混合斑的占比高于对照组(P<0.05),扁平斑、硬斑的占比低于对照组(P<0.05)。观察组血管狭窄率高于对照组(P<0.05)。观察组收缩、舒张末期血流速度均小于对照组,且阻力指数大于对照组(P<0.05)。结论彩色多普勒超声检查能有效识别脑梗死患者颈动脉粥样硬化斑块形成情况,可判定斑块类型、血管狭窄程度以及颈动脉血流信息。

Objective To explore diagnostic value of color Doppler ultrasound for carotid atherosclerotic plaque of cerebral infarction.Methods The paper chose 50 patients with cerebral infarction in the hospital from May 2021 to September 2023(observation group)and 50 healthy individuals(control group)for color Doppler ultrasound examination.Arterial thickening and plaque formation was compared between two groups,plaque type and degree of vascular stenosis was analyzed.Carotid blood flow indicators were compared.Results Thickening rate,plaque formation rate,and multiple plaque rate of carotid intima-media in observation group was higher than control group(P<0.05).Plaques in the two groups mainly concentrated in the bifurcation of the carotid artery,the proportion of plaques in the observation group was 55.81%,and that in the control group was 52.38%(P>0.05).Rates of soft spots and mixed spots in observation group were higher than control group(P<0.05).Incidence of vascular stenosis in observation group was higher than control group(74.00%vs 12.00%,P<0.05).End systolic and diastolic blood flow velocities in observation group were both lower than control group;resistance index was higher than control group(P<0.05).Conclusion Color Doppler ultrasound can identify formation of carotid atherosclerotic plaque of patients with cerebral infarction effectively,and determine plaque type,deg ree of vascular stenosis and carotid blood flow information.
