彩色多普勒超声在脑梗死患者颈动脉病变中的应用价值

Diagnostic value of color Doppler sonography of carotid artery diseases in patient with cerebral infarction

目的:应用彩色多普勒超声检查初步探讨脑梗死与颈动脉粥样硬化病变的关系及特点。方法:对52例脑梗死患者和49例非脑梗死患者进行颈动脉彩色多普勒超声检查。结果:52例脑梗死患者有颈动脉粥样硬化斑块形成者35例,检出率67.3%。颈动脉粥样硬化斑块好发于颈动脉分叉处。软斑、溃疡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相关性。彩色多普勒超声检测脑梗死患者颈动脉粥样硬化斑块形成有重要临床价值。

Objective To study the relationship between the cerebral infarction and carotid atherosclerosis with color Doppler sonography. Methods Color Doppler ultrasonography was applied to 52 cases of cerebral infarction group and 49 cases of non-cerebral infarction group. Results In 52 patients with cerebral infarction, 35 （67. 3%） had Carotid artherosclerotic plaques. Carotid artherosclerosis plaques were more common in the bifurcation. The soft and ulcer plaque constituted major source of cerebral thrombus. Conclusion There is a significant positive linear correlation between carotid artherosclerosis and cerebral infarction. Carotid artery sonographic examination has an important clinical value in patient with cerebral infarction.
