The "congestion index" is used to mean the ratio between the cross-sectional area (cm2) and the blood flow velocity (cm/sec) of the portal vein, as determined by a duplex Doppler system. The indices as determined in normal subjects and patients with liver disease were as follows: normal subjects (n = 85), 0.070 +/- 0.029 cm X sec; acute hepatitis (n = 11), 0.071 +/- 0.014 cm X sec; chronic active hepatitis (n = 42) 0.119 +/- 0.084 cm X sec; cirrhosis (n = 72), 0.171 +/- 0.075 cm X sec; and idiopathic portal hypertension (n = 11), 0.180 +/- 0.107 cm X sec. There was a statistically significant difference between the congestion indices from the normal subject group and indices obtained from patients with chronic hepatitis, cirrhosis, and idiopathic portal hypertension. A weak positive correlation was obtained between the congestion index and the portal venous pressure, measured simultaneously through a percutaneously placed catheter (n = 64, r = 0.45, p less than 0.01). It is suggested that the congestion index reflects the pathophysiological hemodynamics of the portal venous system in portal hypertension.
“充血指数”用于表示由双功多普勒系统测定的门静脉横截面积（cm²）与血流速度（cm/秒）之比。正常受试者和肝病患者所测定的指数如下：正常受试者（n = 85），0.070±0.029 cm×秒；急性肝炎（n = 11），0.071±0.014 cm×秒；慢性活动性肝炎（n = 42），0.119±0.084 cm×秒；肝硬化（n = 72），0.171±0.075 cm×秒；特发性门静脉高压（n = 11），0.180±0.107 cm×秒。正常受试者组的充血指数与慢性肝炎、肝硬化和特发性门静脉高压患者所获得的指数之间存在统计学上的显著差异。通过经皮放置的导管同时测量时，充血指数与门静脉压力之间存在弱正相关（n = 64，r = 0.45，p＜0.01）。提示充血指数反映了门静脉高压时门静脉系统的病理生理血流动力学。
