目的 探讨缺血性脑血管疾病颈动脉粥样硬化斑块的超声声像图特征及其意义。方法 对 441例缺血性脑血管疾病患者,采用二维及Doppler超声观察颈总、颈内动脉粥样硬化斑块及其回声特征,并对短暂性脑缺血发作(TIA)、动脉粥样硬化性脑梗死(AI)及腔隙性脑梗死(LI)进行比较。结果 TIA和AI患者颈动脉粥样硬化斑块的发生率分别为66.5%和71.5%,明显高于LI患者;前两者低回声及混合回声斑块的发生率也高于后者。结论 TIA及AI与颈动脉粥样硬化关系密切,颈动脉超声检查有助于预测其发病风险。 |

Objective To evaluate the significance of the carotid atherosclerosis plaque detected and characterized by ultrasound in ischemic cerebrovascular disease. Methods Carotid arteries of 441 patients with ischemic cerebrovascular disease were examined with two-dimensional and Doppler ultrasound. The echogenicity of the atherosclerosis plaque was studied and compared among transient ischemic attack (TIA), atherothrombotic infarction (AI) and lacunar infarction (LI). Results The percents of atherosclerosis plaque in patients with TIA and AI were 66.5% and 71.5% respectively, both higher than that of LI. The percents of hypoechoic and heterogeneous plaques were also high in patients with TIA and AI. Conclusion Carotid atherosclerosis is significantly relative with TIA and AI. Ultrasonography is useful in the risk assessment for TIA and AI. |
