To evaluate the accuracy of venous duplex, results obtained in 101 patients are compared with venography. A first group consisted of 48 patients with clinically suspected deep vein thrombosis. In 30 of them a positive duplex scan was obtained and all had subsequently a positive venography. Eighteen patients with a normal duplex scan had a normal venography. Another group of 53 patients were tested preoperatively for varicose vein surgery. No obstruction of the venous system was withheld with duplex but 3 patients had an old thrombosis on venography. Thus duplex is a highly reliable method to detect proximal thrombosis in clinically suspected patients but detection of late sequelae of thrombosis may be more difficult.
为评估静脉双功超声的准确性，将101例患者的检查结果与静脉造影结果进行比较。第一组由48例临床怀疑有深静脉血栓形成的患者组成。其中30例双功超声扫描呈阳性，随后所有患者静脉造影均呈阳性。18例双功超声扫描正常的患者静脉造影也正常。另一组53例患者在术前接受了静脉曲张手术检查。双功超声未发现静脉系统有梗阻，但静脉造影显示3例患者有陈旧性血栓形成。因此，双功超声是检测临床疑似患者近端血栓形成的高度可靠方法，但检测血栓形成的晚期后遗症可能更困难。
