目的:探讨脑梗死患者颈动脉彩超与TCD联合检查的意义。方法:对经CT及MRI检查确诊为脑梗死患者进行颈动脉彩超检查与TCD检查。结果:颈动脉超声检查结果颈动脉粥样硬化伴斑块形成者124例,其中106例为多发不均质斑块;TCD检查脑动脉硬化患者117例。结论:颈动脉彩超与TCD联合检查,对于提高脑血管病的诊断准确率具有重要的临床价值。 Objective: To investigate the significance of carotid ultrasonography and TCD in patients with cerebral infarction. Methods: Carotid ultrasonography and TCD were performed on patients diagnosed as cerebral infarction by CT and MRI. Results: There were 124 cases of carotid atherosclerosis with plaque formation in carotid artery ultrasound examination, of which 106 cases were multiple non-homogeneous plaque. TCD was used to detect 117 cases of cerebral arteriosclerosis. Conclusion: The combination of carotid ultrasonography and TCD has important clinical value in improving the diagnostic accuracy of cerebrovascular diseases.
