Compression ultrasound (US) is an excellent means of evaluating the femoral and popliteal veins but is generally regarded as inadequate for the diagnosis of calf vein thrombosis. This prospective study evaluated compression sonography of the calf veins in 45 symptomatic patients with normal femoral and popliteal veins. All patients underwent correlative venography. Compression US enabled identification of 15 of 17 patients with calf vein thrombosis (sensitivity, 88%). The two false-negative results were in patients with small isolated thrombi. Compression US results were true-negative in 26 of 27 patients with normal venograms (specificity, 96%). If these results can be duplicated by other investigators in larger series of patients, compression US will be an adequate screening modality for calf vein thrombosis.
加压超声（US）是评估股静脉和腘静脉的一种极佳方法，但一般认为其不足以诊断小腿静脉血栓形成。这项前瞻性研究评估了45例股静脉和腘静脉正常的有症状患者的小腿静脉加压超声检查。所有患者均接受了相关的静脉造影检查。加压超声能够识别出17例小腿静脉血栓形成患者中的15例（敏感性为88%）。两个假阴性结果出现在有小的孤立血栓的患者中。在27例静脉造影正常的患者中，加压超声结果有26例为真阴性（特异性为96%）。如果其他研究者在更大系列的患者中能重复这些结果，加压超声将成为小腿静脉血栓形成的一种充分的筛查方式。
