In 50 normal subjects flow velocity and direction on the portal vein was measured by ultrasonic duplex system. The measurements revealed at a mean diameter of 9.7 mm, a mean flow velocity of 15.2 +/- 2.6 cm/s, corresponding to a volume flow of 693 +/- 235 ml/min. Postprandially this increased to 880 +/- 269 ml/min. Inter-observer and day to day measurements demonstrated good reproducibility. Thus, this simple non-invasive method is well suited for quantitative assessment of the portal vein system in portal hypertension, thrombosis or after shunt operations.
在50名正常受试者中，使用超声双功系统测量门静脉的血流速度和方向。测量结果显示，平均直径为9.7毫米，平均血流速度为15.2±2.6厘米/秒，相应的血流量为693±235毫升/分钟。餐后血流量增加至880±269毫升/分钟。观察者间和每日测量显示出良好的可重复性。因此，这种简单的非侵入性方法非常适合用于门静脉高压、血栓形成或分流手术后门静脉系统的定量评估。
