The results were: (l)After TAE, portal venous flow and velocity were increased, but portal venous diameter had no significant change.
结果为：①TAE后门静脉血流速度及血流量均较栓塞前增加，而门静脉的内径无明显改变；
Objective To investigate correlation of abnormal sublingual collaterals in patients with primary hepatic carcinoma and portal venous flow alteration.
目的：探讨原发性肝癌异常舌下络脉的特征与门静脉血流动力学变化的相关性。
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。
Portal venous velocity index (PVI) was defined as the ratio of PVV to graft weight (GW), and portal flow volume index (PFI) as the ratio of PVF to GW.
门静脉流速指数(PVI)被定义为PV V与移植物重量(GW)的比率，门静脉血流量指数(PFI)为PVF与GW的比率。
