Venous occlusion plethysmography (VOP) was originally developed to study the physiology of the arterial circulation in the extremities. Improvements in plethysmographic instruments have now made bedside evaluation of peripheral hemodynamics feasible. In recent years, VOP has been employed for the detection of deep vein thrombosis. Combined analysis of the venous volume increase and the subsequent venous outflow in 3 sec, and measured by impedance plethysmography, has produced a 95% correlation with venography in detecting thrombosis of the popliteal, femoral, and iliac veins in 390 limbs. The method is inadequate for detection of isolated calf thrombi.
静脉阻塞体积描记法（VOP）最初是为研究四肢动脉循环的生理学而开发的。如今，体积描记仪器的改进使得床边评估外周血流动力学成为可能。近年来，VOP已被用于检测深静脉血栓形成。通过阻抗体积描记法测量3秒内静脉容量增加及随后的静脉流出量，并进行综合分析，在检测390条肢体的腘静脉、股静脉和髂静脉血栓形成方面，与静脉造影的相关性达95%。该方法对于检测孤立的小腿血栓并不适用。
