摘　　要：目的　探讨二维及彩色多普勒超声在检查下肢动脉粥样硬化中的价值。方法　对 5 2例下肢动脉粥样硬化患者 ,依次从股动脉至足背动脉进行二维结合彩色多普勒超声检查 ,取最大狭窄段及狭窄后段测定动脉血流收缩期峰值血流速度、舒张期反向血流速度及舒张晚期正向血流速度 ,观察频谱形态 ,并与 15例健康人对照。结果　 级狭窄者 2 4例 ,二维高频发现斑块 ,频谱多普勒测定上述血流参数值较对照组变化小 ; - 级狭窄者2 6例 ,二维高频发现明显斑块 ,频谱多普勒测定上述血流参数值较对照组明显减低 ; 级狭窄者二例动脉闭塞段无血流显示。结论　通过二维及彩色多普勒超声测量及频谱分析可早期诊断下肢动脉粥样硬化 ,确定动脉狭窄程度及部位 ,为下肢动脉供血提供量化指标 ,因此两者结合在下肢动脉硬化诊断中具有重要价值。Objective To evaluate the value of analysis combining B-mode sonography and color Doppler ultrasound in detection of lower limb atherosclerosis.Methods The color Doppler ultrasound and pulsed DW of the lower limb blood flow in 52 patients and 15 normal controls were examined.Results By comparison of the patient group(PGp)to the controls(CGp),in 24 cases with stenosis degree I(SDI),atheromatous plagues were found no different systolic peak indices of the blood flow with those of the CGp;in 26 cases with SD Ⅱ-Ⅲ,obveous atheromatous plagues were present with lower systolic peak indices than those of the CGp;in 2 cases in PGp with SD IV,no flow could be seen.Conclusions B-mode and color Doppler ultrasound is useful and important in early dignosis of lower limb atherosclerosis.
