Abstract: AIM To study the interface among intima-media thickness（IMT）, hemodynamics and vascular elasticity of femoral artery（FA） in normal subjects by color Doppler ultrasonography and to analyze the influential factors.METHODS Two-dimensional and color Doppler ultrasonography were used to examine the femoral arteries in sixty normal subjects.The IMT,diameters and peak velocities（Vs） of systolic and diastolic period,velocity-time integra of early diastolic period and time from R peak of ECG to the start of systolic wave(TR-Vs) were measured and the stiffness index（β） and parameters about vascular distensibility and compliance were calculated.RESULTS With age increased,the IMTs,diameters and β increased while the Vmax,TRVs and parameters about vascular distensibility and compliance decreased.The correlation between IMT and β or the correlation between IMT and distensibility and compliance was not significant.CONCLUSION IMT,Vmax and TR-Vs will affect the changes of structure and function characters of femoral artery and can be used as new indexes in evaluating atherosclerosis of femoral artery.
