高频超声检测脑梗塞患者的颈动脉粥样硬化

High frequency ultrasonographic evaluation of carotid atherosclerosis in patients with cerebral infarction

目的 探讨颈动脉粥样硬化与脑梗塞的关系。方法 对109例经CF证实的脑梗塞患者的颈动脉超声结果,进行回顾性分析。结果 脑梗塞患者的颈动脉粥样硬化斑块的发生率占71.56％,斑块的好发部位以分叉处最多见,往往两侧同时受累,其次为颈内动脉起始段,左侧高于右侧,性别无明显差异。斑块的性质与脑梗塞的发生、发展及预后关系密切,软斑及溃疡斑不仅易造成管腔狭窄,而且易破裂,出血及血栓形成,故脑梗塞的发生率高,预后较差。结论 高频超声检查颈动脉,不仅能对脑梗塞患者的预后进行评估,而且能对无症状的动脉硬化患者进行预报和随访。

Purpose To assess the relationship between carotid atherosclerosis and cerebral infarction. Methods High frequency ultrasonagraphic images of carotid artery in 109 patients with cerebral infarction confirmed by CT were analyzed retrospectively. Results 71.56% patients had arteriosclerotic plaques within carotid arteries. Usually the plaque was located at the bifurcation of the carotid artery, especially both sides. Secondly location was the beginning segment of the carotid artery with higher occurrence on left side than on right side and no preference over sex. The nature of the plague had direct relationship to the occurrence, development and prognosis of cerebral infarction. Soft and ulcerous plaques were not only block the cavity, but also easy to break and hemorrhage resulting in the thrombosis. So the cerebral infarction had high occurrence ratio and poor prognosis. Conclusion Carotid artery high frequency Ultrasonographic examination not only make evaluation to the prognosis of the patients suffering from cerebral infarction, but also predict the occurence of cerebral infarction.
