ResultsThe sensitivity and specificity of color ultrasound for stenosis of carotid bifurcation, subclavicular artery and vertebral artery were 96.8%, 80.6%, 60.0% and

结果 本组患者彩色多普勒超声检查对诊断颈动脉分叉部狭窄的敏感性和特异性分别为96.8％和80.6%，对锁骨下动脉狭窄为60.0%和98.7%，对椎动脉狭窄为33.3%和89.0%。

The accuracy of color ultrasound for stenosis of carotid bifurcation, subclavicular artery and vertebral artery were 93.0%, 92.8% and 82.1%.conclusion color ultrasound examination are effective for the diagnosis of carotid bifurcation sterosis, and less effective for the diagnosis of the subclavicular and vertebral artery stenosis because of the poor sensitivity.

彩色多普勒超声检查诊断颈动脉分叉部、锁骨下动脉和椎动脉狭窄的准确度为93.0%、92.8%和82.1%。结论彩色多普勒超声检查可作为诊断颈动脉分叉部位血管狭窄的有效方法；而其对锁骨下动脉及椎动脉狭窄的敏感性较低，诊断价值不大。
