摘要
应用脉冲多普勒超声观测40例正常人和60例肝硬化门脉高压患者门脉系统血管的最大流速、血流量、血管直径、淤血指数和血管阻力指数。结果发现:肝硬化门脉高压患者门脉系统动、静脉属支皆处于高血流状态,门脉主干的淤血指数较正常人高,门脉系统动脉属支阻力指数均较正常人低。
In this experiment, we measured the velocity and volume of the maximal blood flow, the diameter of vessel, the congestion index and the resistance index of the portal vein system by using pulse Doppler ultrasonic detector in 40 normal persons and 60 patients with liver cirrhosis and portal hypertension. We found that there were high blood flow states in the arterial and the veinous branches of the portal vein system. There were higher congestion indexes and lower pusatility indexes in these patients than in normal persons.
