摘要
目的 :研究原发或转移性肝癌肝动脉栓塞术治疗前后肝脏血流动力学改变。方法 :采用彩色多普勒速度能量图分别测量肝癌肝动脉栓塞治疗前后肝动脉、门静脉血管内径及血流速度。结果 :门静脉内径及平均血流速度无明显改变 ,肝动脉内径无明显变化 ,但收缩期峰值明显降低 (P <0 0 5)。结论 :肝癌肝动脉栓塞术治疗后门静脉血流无明显变化 ,对肝脏本身供血无影响。肝动脉收缩期峰值流速明显降低 。
Objective:To study the changes of liver blood flow before and after the treatment of hepatic artery embolization in hepatocarcinoma.Methods:The diameter and blood velocity of hepatic artery (HA) and portal vein (PV) were measured with color Doppler flow imaging.Results:The diameter and average blood velocity of PV did not change significantly.The diameter of HA did not change,but the systolic peak blood velocity of HA dropped significantly (P<0 05).Conclusions:The blood flow of PV does not change after the treatment of hepatic artery embolization.The blood flow of liver does not reduce.The systolic peak blood velocity of hepatic artery drops obviously.The blood supply of the tumor,whose blood is mainly supplied by HA,decreases obviously.
