Abstract:
Objective To study the common femoral artery haemodynamics caused by different degrees of abdominal aorta extremity stenosis.Methods The lateral walls of abdominal aorta extremity were pinched with vascular clamp resulting in 1/3,1/2,2/3,3/4 stenosis by turns in 6 juvenile susscrota domesticas.The parameters of peak systolic velocity(PSV),minimum diastolic velocity(MDV),PSV/MDV(S/D)and MDV/PSV(D/S)of common femoral artery were obtained and their correlations with degrees of abdominal aorta extremity stenosis were confirmed by statistical analysis.Results The backwardware vanished or turned to forwardware when stenosis achieved certain degree.PSV had significant negative correlation with stenosis degree(R=0.985,R2=0.969),but D/S had significant positive correlation with stenosis degree when stenosis degree exceed 1/3(R=0.918,R2=0.843).Conclusions It can be concluded there is proximal stenosis disease and change of distal effective circulating blood volume according to the Doppler velocity tracing analysis.PSV and D/S are valuable parameters,however waveform should be ignored.
