ABSTRACT
Objective To evaluate Color Doppler ultrasonography follow up for patients of femoropopliteal arteriosclerosis after interventional therapy.Methods We used Color Doppler ultrasound (CDU) in 57 cases' follow-up of endovascular intervention therapy of femoropopliteal arteriosclerosis lesion to monitor and analyze arterial hemodynamics after endovascular intervention therapy.Results An average follow-up of 13 months( range:3 -33 ) was achieved.31 of the 57 cases were found with mild stenosis,8 cases were moderate stenosis,6 cases were severe stenosis,12 cases were complete occlusion.In these 57 cases there were 7 in Fontaine stage Ⅰ,42 cases in Fontaine stage Ⅱ,6 cases were Fontaine stage Ⅲ,2 cases were Fontaine stage Ⅳ.Ankle brachial index (ABI) ABI≥I.0 in 2 cases,0.8≤ABI < 1.0 in 10 cases,0.8≤ABI < 1.0 in 31 cases,and ABI <0.5 in 14 cases.There was significant correlation between stenosis and Fontaine stage ( r =0.47,P < 0.01 ),so was between stenosis and ABI ( r =0.66,P < 0.01 ).In this series 29 cases also underwent DSA,and the results between CDU and DSA were significandy consistent ( Kappa value =0.61,P < 0.01 ).The sensitivity of CDU was 92%,the specificity was 75% and the accuracy was 89.2%.Conclusions CDU can continuously monitor hemodynamics after endovascular intervention therapy.It is a sensitive,non-invasive and effective method to evaluate the clinical efficacy of endovascular intervention.
