50 cases, in which phlebography was indicated by clinical symptoms of deep venous thrombosis, were examined by duplex-sonography. In comparison with the phlebographic findings, duplex-sonography was 100% sensitive in detecting thrombosis of the popliteal, femoral and iliac veins and 89% respectively 95% and 100% specific. A sonographic performance of the calf veins was only possible in 44%, the sensitivity in these cases was 92%, specificity 50%. Thus, the non-invasive duplex-sonography is a very appropriate method to diagnose thrombosis of the popliteal region and proximal. For proving or excluding thrombosis of the calf veins phlebography remains necessary.
50例有深静脉血栓临床症状而需行静脉造影检查的患者接受了双功超声检查。与静脉造影结果相比，双功超声检测腘静脉、股静脉和髂静脉血栓的敏感性为100%，特异性分别为89%、95%和100%。仅44%的患者能够对小腿静脉进行超声检查，这些病例的敏感性为92%，特异性为50%。因此，非侵入性双功超声是诊断腘静脉区域及近端血栓形成的非常合适的方法。要证实或排除小腿静脉血栓形成，仍需要进行静脉造影检查。
