目的研究颈动脉粥样硬化病变特点和颈动脉内膜中层厚度(IMT)与脑梗死的关系。方法对观察组100例急性脑梗死患者和对照组100例同期体检的健康者进行颈动脉彩色多普勒超声检查,检测双侧颈总动脉、颈动脉分叉和颈内动脉IMT和颈动脉粥样硬化斑块情况。结果观察组颈动脉粥样硬化检出率为76.1%,以软斑、溃疡斑和混合斑为主;对照组颈动脉粥样硬化检出率为37.8%,以硬斑和扁平斑为主,两组差异有统计学意义(P<0.05)。观察组颈总动脉、颈动脉分叉和颈内动脉IMT均显著大于对照组(P<0.05)。结论颈动脉粥样硬化斑块的形成是造成脑梗死的主要原因,颈动脉超声检查能准确显示斑块的形态、大小、位置及管腔狭窄程度,对脑梗死的早期预防和治疗具有重要的临床价值。
Objective To study the relationship between carotid atherosclerosis and carotid intima-media thickness (IMT) and cerebral infarction. Methods 100 cases of acute cerebral infarction in the observation group and the control group 100 cases of physical examination in the same period of carotid color Doppler ultrasound examination of bilateral common carotid artery, carotid bifurcation and internal carotid artery IMT and carotid atherosclerosis Like the case of plaque. Results The detection rate of carotid atherosclerosis in observation group was 76.1%, mainly with soft spot, ulcer spot and mixed spot. The incidence of carotid atherosclerosis in control group was 37.8%, mainly with plaque and flat plaque, The difference between the two groups was statistically significant (P <0.05). The carotid artery bifurcation and internal carotid artery IMT in observation group were significantly greater than those in control group (P <0.05). Conclusion Carotid artery atherosclerotic plaque formation is the main cause of cerebral infarction. Carotid ultrasonography can accurately show the plaque morphology, size, location and degree of stenosis. It is important for the early prevention and treatment of cerebral infarction Clinical Value.
