摘　　要：目的探讨2型糖尿病患者股动脉血管弹性及下肢血流动力学的变化。方法 应用血管回声跟踪(echo-tracking,ET)技术,采集30例正常人和54例2型糖尿病患者的股动脉的二维超声图像,测量双侧股动脉内中膜厚度(IMT);应用脉冲多普勒技术(PW)测量股动脉血流阻力指数(RI)、搏动指数(PI);应用ET技术检测弹性指标β。结果按照IMT是否<1.0mm分组后显示:糖尿病IMT<1.0mm组及糖尿病IMT≥1.0mm组的股动脉血流动力学参数RI、PI及弹性指标β均较对照组差异有统计学意义(P<0.05);糖尿病IMT≥1.0mm组的股动脉血流动力学参数RI、PI及弹性指标β较糖尿病IMT<1.0mm组差异有统计学意义(P<0.05)。结论糖尿病患者下肢动脉在动脉粥样硬化的形态学改变出现之前,血管壁弹性功能已降低,且影响血流动力学,有可能造成外周组织血液供应不良。Objective To detect the elasticity of femoral artery in type 2 diabetic patients by echo-tracking（ET） technique.Methods Thirty healthy subjects（control group） and fifty-four T2DM patients were enrolled in this study.The longitudinal view of femoral（FA） was displayed by two-dimensional ultrasonic imaging and intima-media thickness（IMT） of these arteries,RI,PI were measured.The stiffness parameter（P0.05） of these arteries were automatically by ET technique.Results Subject the patients into three groups by the criterion that IMT1.0mm,RI,PI,β were significantly higher（P0.05） in the T2DM group than those in the control group.Conclusion There are functional and hemodynamics changes of lower limbs in T2DM patients before morphology changes.
