彩色多普勒超声评价脑梗死和颈动脉斑块的临床价值

目的探讨彩色多普勒超声评价脑梗死和颈动脉斑块之间的联系。方法对225例脑梗死患者进行颈动脉彩色多普勒超声检查，分别观察颈动脉有无斑块，发观有颈动脉斑块者，测量颈动脉的内一中膜厚度、斑块大小及血管内血流动力学指标，并观察有无血管狭窄。结果225例脑梗死患者超声检查有197例出现颈动脉内．中膜增厚，合并粥样硬化斑块形成。斑块出现部位多集中在颈总动脉分叉处，其中扁平斑块78例，软斑块64例，溃疡型斑块31例，硬斑块24例。结论粥样硬化的颈动脉斑块形成与脑梗死的发生有密切关系，彩色多普勒超声检查颈动脉粥样硬化对预测脑梗死有重要的临床意义。

Evaluation of color Doppler ultrasonography for carotid plaque and cerebral infarction

Objective To explore the connection between carotid plaque and cerebral infarction by color Doppler uhrasanography. Methods Color Doppler ultrasonography was used for the examination of the carotid of 225 patients with cerebral infarction to discover whether there were carotid plaques or not. If there were carotid plaques, measured the thickness of the carotid artery intima-media membrane, the size of plaques, blood vessel hemodynamic parameter and observed whether the blood vessel became narrow. Results Among the 225 patients with cerebral in- farction, color Doppler ultrasonography showed increasing thickness of carotid artery intima-media membrane com- bined with plaques forming in 197 patients. Plaques appeared mostly in the crotch of common carotid artery, among which flat plaques were found in 78 cases, soft plaques in 64 cases, ulcerous plaques in 31 cases, and tough plaques in 24 cases. Conclusion The formation of atheresclerostic plaque in carotid arteries had close relationship with the occurrence of cerebral infarction. Applying color Doppler ultrasonography to the examination of carotid athemsclerosis has clinical significance in prognosticating and treating cerebral infarction.
