股腘动脉闭塞腔内治疗的彩色多普勒超声随访检查

目的 评价彩色多普勒超声在股腘动脉闭塞腔内治疗患者随访中的临床应用价值.方法 应用彩色多普勒超声对57例股腘动脉闭塞腔内治疗患者进行随访,检测腔内治疗术后动脉内血流动力学变化.结果 本组57例均获随访,随访率100％.随访时间3～33个月,平均(13±7)个月.经彩色多普勒超声检查后发现患肢动脉轻度狭窄31例,中度8例,重度6例,完全闭塞12例；57例中FontaineⅠ期7例,Ⅱ期42例,Ⅲ期6例,Ⅳ期2例；ABI≥1.0有2例,0.8≤ABI＜ 1.0有10例,0.5≤ABI ＜0.8有31例,ABI＜0.5有14例.动脉狭窄程度与Fontaine分期和ABI指数均呈正相关性(r =0.47,P＜0.01；r =0.66,P＜0.01).29例同时接受DSA检查,超声和DSA检查结果具有显著一致性(Kappa值=0.61,P＜0.01),超声诊断股腘动脉闭塞的敏感性92.0％ (23/25),特异性75.0％ (3/4),准确性89.7％(26/29).结论 彩色多普勒超声可实时监测腔内治疗术后股腘动脉血流动力学变化,是评估临床疗效有效的无创检查方法.

Color Doppler ultrasound follow-up for patients of femoropopliteal arteriosclerosis undergoing endovascular intervention therapy

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.
