目的彩色多普勒超声对糖尿病颈部血管病变的诊断意义。方法用彩色多普勒超声诊断仪检测110例糖尿病患者颈部动脉血管,观察内膜、斑块、管腔狭窄程度及血流动力学改变。结果75%的患者有不同程度内膜增厚,59%的患者有斑块形成,其中约24%有不同程度管腔狭窄。结论糖尿病病人颈部血管病变发病率高,彩色多普勒超声检查是动态观察病变程度、进展情况的有效方法。 Objective To evaluate the diagnostic value of color Doppler ultrasound in the diagnosis of diabetic cervical vascular disease. Methods The neck artery of 110 diabetic patients was examined by color Doppler sonography. The intima, plaque, luminal stenosis and hemodynamic changes were observed. Results 75% of patients had varying degrees of intimal thickening, 59% of patients had plaque formation, of which about 24% have varying degrees of stenosis. Conclusion The incidence of cervical vascular disease in diabetic patients is high. Color Doppler ultrasonography is an effective method to dynamically observe the degree and progress of lesions.
