目的应用彩色多普勒超声检查初步探讨颈动脉硬化斑块与脑梗死的关系。方法对83例颈动脉粥样硬化斑块检出者均行头部CT或核磁共振(MRI)检查证实有无梗死发生。结果 83例颈动脉粥样硬化斑块检出者经检查证实有梗死灶发生49例(59%),其中有典型临床症状23例(27%)。颈动脉粥样硬化斑块好发于颈动脉分叉处。软斑、混合斑是脑梗死患者的主要栓子来源。结论颈动脉粥样硬化斑块与脑梗死有密切的相关性。
Objective To investigate the relationship between carotid plaque and cerebral infarction with color Doppler ultrasonography. Methods 83 cases of carotid atherosclerotic plaques detected by head CT or magnetic resonance imaging (MRI) to confirm the presence of infarction. Results 83 cases of carotid atherosclerosis plaque detected by the examination showed 49 cases of infarction (59%), of which 23 cases were typical clinical symptoms (27%). Carotid atherosclerotic plaques occur at the bifurcation of the carotid artery. Soft plaque, mixed plaque is the main source of emboli in patients with cerebral infarction. Conclusion Carotid atherosclerosis plaque is closely related to cerebral infarction.
