“充血指数”用于表示门静脉的横截面积（cm 2）和血流速度（cm/sec）之间的比率，如通过双工多普勒系统所确定的。在正常受试者和肝病患者中测定的指数如下：正常受试者（n = 85），0.070 ±。0.029厘米×急性肝炎11例，0.071 ±。0.014厘米×秒;慢性活动性肝炎（n = 42），0.119。±。0.084厘米×sec;肝硬化（n = 72），0.171 ±. 0.075厘米×sec;和特发性门静脉高压症（n = 11），0.180 ±。0.107厘米×秒正常受试者组的充血指数与慢性肝炎、肝硬化和特发性门脉高压患者的充血指数之间存在统计学显著差异。充血指数与经皮穿刺置管同时测定的门静脉压力呈弱正相关（n = 64，r = 0.45，p < 0.01）。提示充血指数反映了门静脉高压症时门静脉系统的病理生理血流动力学。
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 .times. sec; acute hepatitis (n = 11), 0.071 .+-. 0.014 cm .times. sec; chronic active hepatitis (n = 42), 0.119 .+-. 0.084 cm .times. sec; cirrhosis (n = 72), 0.171 .+-. 0.075 cm .times. sec; and idiopathic portal hypertension (n = 11), 0.180 .+-. 0.107 cm .times. 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 < 0.01). It is suggested that the congestion index reflects the pathophysiological hemodynamics of the portal venous system in portal hypertension.
