| 目的 探讨颈动脉内径狭窄小于70%的短暂性脑缺血发作患者(TIA)脑梗死发病和颈动脉粥样硬化斑块的关系。方法 颈动脉内径狭窄小于70% 的TIA患者123人,采用二维及Doppler超声观察颈动脉有无粥样硬化斑块及其类型,并随访脑梗死的发生率。结果 114例患者完成观察,平均随访14.6个月,发生脑梗死12例,其中无斑块组患者脑梗死年发生率为1.9%,稳定性斑块组为4.7%,不稳定性斑块组为15.4%,后者明显高于前二者。结论 超声可对颈动脉粥样斑块分型,有助于预测TIA患者脑梗死的发病风险。 |

| Objective To evaluate the significance of the carotid atherosclerosis plaque for brain infarction in patients with transient ischemic attack(TIA), whose carotid diameter stenosis was smaller than 70%. Methods One hundred and twenty-three patients in TIA were followed up, the atherosclerosis plaque were studied with two-dimensional and Doppler ultrasonography, the significance of plaque for brain infarction was studied. Results One hundred and fourteen patients whose average duration of follow-up was 12.6 months finished study, 12 patients suffered from brain infarction. The annual incidence of brain infarction of patients with vulnerable plaques was 15.4%, which was higher than that of patients without plaque and patients with stable plaques, whose annual incidence of brain infarction were 1.9% and 4.7% respectively. Conclusion Characteristics of carotid atherosclerosis plaque as evaluated by ultrasonography are useful in the indication of brain infarction in patients with transient ischemic attack. |
