To evaluate the serial hemodynamic changes that occur after transcatheter arterial embolization (TAE) of hepatocellular carcinomas (HCCs).
Twenty patients with HCCs treated with TAE were evaluated with color and duplex Doppler sonography before, immediately after, and 2 days after TAE. The changes in hepatic artery and portal vein velocity and flow were evaluated.
The portal venous velocity and flow did not change significantly after TAE. The peak systolic velocity in the proximal hepatic artery decreased significantly (P < .01) immediately after TAE then returned to baseline values 2 days after TAE; the resistance index of the proximal hepatic artery increased significantly (P < .01) immediately after embolization, then returned to baseline values 2 days after TAE. Arterial signal in the distal hepatic artery, generally absent immediately after TAE, could be recorded 2 days after.
There is a rapidly reversible decrease in hepatic arterial flow induced by embolization, without any change in portal venous flow.
评估肝细胞癌（HCC）经导管动脉栓塞术（TAE）后发生的系列血流动力学变化。
对20例行TAE治疗的HCC患者在TAE前、术后即刻及术后2天进行彩色及双功多普勒超声检查。评估肝动脉和门静脉速度及血流的变化。
TAE后门静脉速度和血流无明显变化。肝动脉近端的收缩期峰值速度在TAE后即刻显著降低（P <.01），然后在TAE后2天恢复至基线值；肝动脉近端的阻力指数在栓塞后即刻显著升高（P <.01），然后在TAE后2天恢复至基线值。肝动脉远端的动脉信号通常在TAE后即刻消失，但在2天后可记录到。
栓塞引起肝动脉血流迅速可逆性降低，门静脉血流无任何变化。
