颈动脉超声检查在脑梗死患者中的应用

目的：探讨颈动脉超声检查在脑梗死患者中的应用价值。方法对144例脑梗死患者和106名健康查体者进行颈动脉超声检查，观察颈动脉内中膜厚度、斑块发生情况及血管狭窄情况。结果脑梗死组较对照组内中膜明显增厚，斑块检出率明显增高。脑梗死组与对照组检出斑块中均以强回声斑块最为多见。脑梗死组与对照组在血管狭窄程度上差异有统计学意义（P＜0.01）。结论动脉粥样硬化是脑梗死发生的主要危险因素之一。颈动脉超声检查可以观察和了解颈动脉粥样硬化的病变及其程度，提示脑血管病变是否处于高危状态，对脑梗死患者的预防和治疗有重要的实用价值。

Clinical Application of Carotid Artery Ultrasonography in Patients with Cerebral Infarction

Objective To study the application of carotid artery ultrasonography in patients with cerebral infarction. Methods 144 patients with cerebral infarction and 106 normal people were examined by carotid artery ultrasonography to observe the intima-media thickness （IMT）, plaque and artery stenosis. Results IMT and the occurrence rate of plaque were significantly higher in cerebral infarction group than those in control group. Most of the plaques in two groups were strong echoes. There was statistical significance in the degree of artery stenosis between two groups （P〈0.01）. Conclusion Atherosclerosis is one of the most risk factors of cerebral infarction. Carotid artery ultrasonography can be diagnostic of the degree of carotid atherosclerosis, and cues whether the patients with cerebral infarction are in high risk, so it plays an important role in the prevention and treatment of patients with cerebral infarction.
