摘　　要：目的：比较彩超不同体位和诱导方法评价静脉瓣功能不全的准确性。方法：３０条慢性静脉瓣功能不全下肢静脉分别进行了卧位乏氏法（卧乏法）和挤压法（卧挤法），其中１４条同时检查了立位乏氏法（立乏法）和挤压法（立挤法）。结果：立、卧位乏氏法比挤压法产生更长的返流时间和更高的峰速度；乏氏法对股总和大隐静脉要好些，而立挤法对静脉和股浅静脉更有效。立位优于卧位，乏氏法与挤压法相结合优于单一方法。卧位乏氏＋挤压法诊断静脉瓣功能不全的敏感性为９４．６％，特异性６９．２％，准确性８９．１％；且患者舒适，特别适合高龄和重症患者，便于临床推广应用。结论：卧位乏氏＋挤压法做为首选方法。ABSTRACT Objective:To explore the effect of CDFI with different patient positions and evoking reflux methods for diagnosing venous valvular incompetence(VVI).Methods:30 Lower limbs veins with chronic venous insufficiency were tested by Valsalva and limb compression maneuver in supine position,14 of 30 in addition of erect position.Results:The reflux times in supine or erect,Valsalva method were longer than that in limb compression maneuver,the velocities achieved the same results.Valsalva method is better for common femoral vein and great saphenous vein.Compression maneuver is more suitable for popliteal vein and superficial femoral vein,especially in erect position,erect was superior to supine.Valsalva combined with compression was better than single method.Valsalva combined with compression in supine position provided the sensitivity 946%，specificity 692% and accuracy 891%.This method can present sufficient clinical informations.It is more practical and more easy to perform for aged and debilitated patients.Conclusion:Valsalva combined with compression maneuver in supine position might be the first of choice for detect VVI.KEY WORDS Chronic venous insufficiency Color Doppler flow imaging
