In patients with portosystemic shunting secondary to portal hypertension, hepatic arterial flow often increases to compensate for reduced portal flow (139, 178) (Fig. 6.4).
因为门脉高压出现门体分流的病人，肝动脉的血流量常常有所增加以补偿减少了的门脉血流(139,178)(如图6.4)。
Methods Portal venous blood flow, hepatic arterial blood flow and resistance index(RI) were determined by duplex Doppler sonography in 56 patients subjected to liver transplantation.
方法应用彩色多普勒超声对56例肝移植患者术前及术后移植肝门静脉、肝动脉血流及肝动脉阻力系数（RI）进行监测。
The liver perfusion parameters including hepatic blood flow(BF), blood volume(BV), mean transit time(MTT), permeability surface area product(PS) and hepatic arterial fraction (HAF)was calculated.
通过扫描软件得出肝血流量（BF）、血容量（BV）、对比剂平均通过时间（MTT）、渗透表面积乘积（PS）、肝动脉灌注指数（HAF）。
