A simple screening procedure is needed to fill the gap between the clinical examination and venography in patients suspected of having deep-vein thrombosis of the lower extremities. The author suggests that measurement of the pedal venous pressure (PVP) be used for this purpose. Measurements of PVP in 86 lower extremities and correlation with venography showed that all extremities with a PVP greater than 35 cm saline were shown to be abnormal on venography, indicating that measurement of PVP can be a satisfactory screening procedure.
需要一种简单的筛查程序来填补疑似下肢深静脉血栓形成患者临床检查与静脉造影之间的空白。作者建议为此目的使用足背静脉压（PVP）测量。对86条下肢的PVP进行测量并与静脉造影进行相关性分析，结果显示，所有PVP大于35 cm盐水柱的肢体在静脉造影中均显示异常，这表明PVP测量可以作为一种令人满意的筛查程序。
