To compare the operating characteristics of the venous echo-doppler and that of venous phlebography in our setting, 90 consecutive patients admitted on suspicion of deep vein thrombosis of one leg underwent both examinations. Phlebography confirmed the diagnosis in 46 patients (51%). The sensitivity, specificity, and positive and negative predictive values of the echo-doppler were 91, 92, 94 and 90% respectively. For the subgroup of patients with proximal deep vein thrombosis, these values were 97, 97, 97 and 97%, respectively; for the subgroup with distal deep vein thrombosis, these values were 60, 95, 75 and 90%, respectively. This study confirms the excellent performance of the venous echo-doppler for the diagnosis of deep vein thrombosis of the leg in our hospital. However, in the subgroup of patients with distal deep vein thrombosis, only the sensitivity of the venous echo-doppler is relatively low and the diagnosis may still require color echo-doppler or phlebography.
为了比较在我们医院静脉超声多普勒检查和静脉造影的操作特性，90例因怀疑单侧下肢深静脉血栓形成而入院的连续患者接受了这两种检查。静脉造影确诊46例患者（51%）。超声多普勒检查的敏感性、特异性、阳性预测值和阴性预测值分别为91%、92%、94%和90%。对于近端深静脉血栓形成的患者亚组，这些值分别为97%、97%、97%和97%；对于远端深静脉血栓形成的患者亚组，这些值分别为60%、95%、75%和90%。本研究证实了静脉超声多普勒检查在我院诊断下肢深静脉血栓形成方面的优异性能。然而，在远端深静脉血栓形成的患者亚组中，只有静脉超声多普勒检查的敏感性相对较低，诊断可能仍需要彩色超声多普勒检查或静脉造影。
