采用彩色多普勒血流显象仪观察肝动脉化疗栓塞术（ＴＡＥ）对原发性肝癌患者肝动脉、门静脉血流速度和血流量的影响。结果显示：ＴＡＥ治疗后肝动脉血流速度、血流量在第１、第３周显著降低，术后第５周基本恢复至术前水平，随着ＴＡＥ治疗次数增加，肝动脉血流量持续减少。ＴＡＥ术后第１、第３、第５周，门静脉血流速度、血流量比术前显著增加，首次ＴＡＥ治疗导致的门静脉血流量增加并不因为ＴＡＥ次数增加而改变。作者认为，为了提高ＴＡＥ治疗效果，术后第５周左右，应再次进行肝动脉栓塞化疗，尽量增加肝癌患者ＴＡＥ治疗次数，除栓塞肝动脉外，还应对门静脉血流进行阻断
The effect of hepatic arterial chemoembolization (TAE) on hepatic artery, portal vein velocity, and blood flow in patients with primary liver cancer was observed by color Doppler flow imaging. The results showed that after TAE treatment, hepatic arterial blood flow velocity and blood flow decreased significantly in the first and third weeks, and returned to the preoperative level in the fifth week postoperatively. With the increase in the number of TAE treatment, hepatic arterial blood flow continued to decrease. After 1st, 3rd, and 5th week after TAE, the velocity and blood flow of portal vein were significantly increased compared with preoperative. The increase of portal venous blood flow caused by the first TAE treatment did not change because of the increase of TAE times. The authors believe that, in order to improve the effect of TAE, about the fifth week after surgery, hepatic artery embolization chemotherapy should be performed again to increase the number of TAE treatment in patients with liver cancer, in addition to embolization of the hepatic artery, but also to block the portal vein blood flow
