One hundred consecutive inpatients with clinically suspected deep venous thrombosis (DVT) were examined by US; the last 19 cases were studied also by means of color-Doppler US. In order to evaluate the method reliability, US results were compared with those obtained with contrast venography, which was performed on all patients. The studied region included the femoro-popliteal vein, while no attempt was made to image the calf veins, which are difficult to evaluate with US. In our series, venographic results were in substantial agreement with US findings, with 99% and 100% sensitivity and specificity, respectively. Diagnosis was based only on noncompressibility of the thrombotic vein, despite the absence of visible clots; pulsed Doppler information supported diagnosis by evaluating blood flow. Further diagnostic progress was provided by color-Doppler US, which allows flow lumen to be defined in color. US also allowed the detection of the conditions mimicking DVT, such as muscular ruptures, hematomas, popliteal cysts, or compressive tumors. In conclusion, US and color-Doppler US prove to be valid alternatives to contrast venography in the diagnosis of proximal DVT of the lower limbs.
对100例临床怀疑有深静脉血栓形成（DVT）的连续住院患者进行了超声检查；对最后19例患者还采用了彩色多普勒超声检查。为了评估该方法的可靠性，将超声检查结果与所有患者均接受的静脉造影结果进行了比较。研究区域包括股腘静脉，未尝试对小腿静脉进行成像，因为小腿静脉难以用超声评估。在我们的系列研究中，静脉造影结果与超声检查结果基本一致，敏感性和特异性分别为99%和100%。诊断仅基于血栓形成静脉的不可压缩性，尽管未见明显血栓；脉冲多普勒信息通过评估血流支持诊断。彩色多普勒超声提供了进一步的诊断进展，它可以用彩色定义血流腔。超声还能检测出模拟DVT的情况，如肌肉破裂、血肿、腘窝囊肿或压迫性肿瘤。总之，在诊断下肢近端DVT方面，超声和彩色多普勒超声被证明是静脉造影的有效替代方法。
