无创血管检查诊断下肢深静脉血栓形成的价值

目的比较多普勒血管检查和彩色多普勒超声（彩超）检查在诊断下肢深静脉血栓形成（DVT）中的价值。方法对146例DVT患者共178侧下肢分别进行深静脉的多普勒血管检查及彩超检查，并以彩超作为诊断标准对结果进行比较。结果彩超对于诊断DVT具有很高的准确性，多普勒血管检查对股、胭静脉病变的阳性诊断率为97．9％（142／145），对下腔静脉、髂静脉、胫前、胫后和腓静脉以及腓肠肌静脉丛血栓的诊断价值低于彩超检查。结论在诊断DVT时，彩超因具有优于多普勒血管检查的优势，可作为诊断的主要手段，多普勒血管检查可以作为初筛的检查方法。静脉造影不应作为诊断DVT的常规检查方法。

Value of noneinvasive vascular examinations in diagnosing deep venous thrombosis

Objective To evaluate the different value of color Doppler ultrnsonography and Doppler vascular examinations in diagnosis for deep venous thrombosis(DVT)in the lower extremities.Methotis Imaging of color Doppler ultrasound scanning was employed as diagnostic criteria for DVT on 178 lower extremities of 146 suspected patients,as compared to the result by Doppler vascular examinations.Results Color Doppler ultrasonograph showed hish accuracy in diagnosis for DVT,as compared to that by Doppler vascular examination with 97.9 percent(142/145)positive for the femoral and popliteal veins and relatively lower positive diagnostic vallie for thrombosis in the inferior vena cava,iliac vein,anterior tibial vein,posterior tibial vein and calf veins.Conclusions Color Doppler ultrasonography is superior to Doppler vascular examination in determining DVT of the lower extremities and can be used as a main diagnostic method for it.Doppler vasculiar examination can be used as an initial screening method for DVT and deep venous angiography should not be used as a routine diagnostic measure for it.
