The contribution of high-resolution real-time ultrasonography to the diagnosis of deep vein thrombosis (DVT) was evaluated in a prospective study performed on 96 patients. 45 patients were also examined with contrast venography and 79 with continuous wave Doppler ultrasound. The femoral and popliteal veins were examined for compressibility by pressure with the transducer probe, response to deep inspiration and Valsalva's manoeuvre and presence of an intraluminal mass. The contralateral veins were routinely screened for comparison. The diagnostic sensitivity versus phlebography was 87%, and the specificity 100% for the femoral vein. When including the popliteal vein the specificity was 91%. Real-time ultrasonography together with Doppler ultrasound examination is an effective non-invasive approach for the diagnosis of DVT. Phlebography can be avoided if these two examinations are unequivocally positive or negative for DVT.
在一项针对96例患者的前瞻性研究中，评估了高分辨率实时超声检查对诊断深静脉血栓形成（DVT）的作用。45例患者还接受了静脉造影检查，79例接受了连续波多普勒超声检查。使用换能器探头对股静脉和腘静脉进行加压检查其可压缩性、对深吸气和瓦尔萨尔瓦动作的反应以及腔内肿块的存在情况。常规检查对侧静脉以作比较。与静脉造影相比，诊断股静脉的敏感性为87%，特异性为100%。若将腘静脉纳入，则特异性为91%。实时超声检查与多普勒超声检查相结合是诊断DVT的一种有效的非侵入性方法。如果这两项检查对DVT明确呈阳性或阴性，则可避免进行静脉造影检查。
