肝硬化门静脉高压症存在严重的门静脉系统血流动力学紊乱。目前正采用多种手段研究其血流动力学改变,本文通过彩色多普勒超声仪观察肝硬化患者的门静脉系统血流动力学改变,现介绍如下。 Cirrhosis Portal hypertension presents with severe portal system hemodynamic disturbances. Currently using a variety of means to study the hemodynamic changes, this paper by color Doppler ultrasound in patients with cirrhosis of the portal vein hemodynamic changes, are described below.
