目的:观察研究超声监测缺血性脑血管病人颈动脉粥样硬化斑块的临床应用价值及缺血性脑血管疾病的预报价值。方法:选择缺血性脑血管病人83例为观察组(组),无脑血管疾病的人员65例为对照组(组),使用双功能彩色多普勒超声仪(探头频率10MHz)观察颈内动脉的内膜、中层和外膜三层结构,发现动脉粥样硬化斑块并确定其大小、范围、表面形态、病变性质及狭窄程度,并准确测定血管壁的厚度、内径、腔面积,同时彩色多普勒显示颈内动脉血流状态及流速、流量。结果:缺血性脑血管疾病病人的颈动脉硬化斑块的检出率明显高于对照组(P<0.01),观察组颈动脉收缩期血流速度峰值(PS)和舒张末期血流速度(ED)明显低于对照组(P<0.05和P<0.01)。结论:超声可以监测颈动脉粥样硬化斑块的存在并可以预报缺血性脑血管疾病
OBJECTIVE: To observe the clinical value of carotid atherosclerotic plaques monitored by ultrasound in the diagnosis of ischemic cerebrovascular disease and the prediction value of ischemic cerebrovascular disease. Methods: 83 patients with ischemic cerebrovascular disease were selected as observation group (group), 65 patients without cerebrovascular disease as control group (group). Bifunctional color Doppler ultrasound (probe frequency 10MHz) Arterial intima, middle and adventitia three-tier structure, found atherosclerotic plaque and to determine its size, extent, surface morphology, lesion nature and degree of stenosis, and accurate determination of vessel wall thickness, diameter, cavity area, at the same time Color Doppler shows the state of internal carotid artery blood flow and flow rate. Results: The detection rate of carotid plaque in ischemic cerebrovascular disease patients was significantly higher than that in the control group (P <0.01). The peak systolic velocity (PS) and end diastolic velocity ED) was significantly lower than the control group (P <0.05 and P <0.01). Conclusion: Ultrasound can monitor the presence of carotid atherosclerotic plaques and predict ischemic cerebrovascular disease
