Clinical evaluation of deep venous thrombosis is often unreliable. Recently it has been shown that deep venous thrombosis may be detected with colour duplex scanning which is safer than phlebography. However it is not clear how colour duplex correlates with phlebography. One hundred and twenty consecutive patients with suspected deep vein thrombosis were studied by colour duplex scanning and phlebography to compare the two methods. Both tests were positive in 102 limbs and negative in 16 limbs. In two cases of below-knee thrombosis colour duplex was negative while phlebography showed small localised thrombosis. The sensitivity of colour duplex was 98%, its specificity and positive predictive value 100% and its negative predictive value 88.8%. In conclusion colour duplex appears to be as effective as phlebography in detecting deep venous thrombosis above knee.

深静脉血栓形成的临床评估通常不可靠。最近,已经显示可以通过彩色双工扫描检测到深静脉血栓形成,这比静脉造影更安全。但是,尚不清楚颜色双工与静脉造影如何相关。通过彩色双工扫描和静脉造影研究了连续120例疑似深静脉血栓形成的患者,以比较两种方法。两项测试在102个肢体中均为阳性,在16个肢体中均为阴性。在两例膝下血栓形成的情况下,彩色双色阴性,而静脉造影显示小的局部血栓形成。98% 了彩色双色的敏感性,其特异性和阳性预测值100%,阴性预测值88.8%。总之,彩色双工在检测膝盖以上深静脉血栓形成方面似乎与静脉造影一样有效。
