摘要目的探讨门静脉逆流与肝癌肝内转移的关系。方法应用彩色多普勒超声检测肝炎肝癌组、非肝炎肝癌组、肝炎组与对照组的门静脉-肝动脉瘘、门静脉逆流的发生率。结果肝炎肝癌组、肝炎组门静脉逆流的发生率均高于非肝炎肝癌组（P＜0.05,P＜0.01)，且肝炎肝癌组最高(P＜0.05 ,P＜0.01,P＜0.001)；肝炎肝癌组肝内转移发生率明显高于非肝炎肝癌组(P＜0.01)；肝炎肝癌组与非肝炎肝癌组肿块内及周围的门静脉-肝动脉瘘发生机率差异无显著性(P＞0.05)。结论门静脉逆流是引起肝癌肝内转移的主要途径。

abstractsObjective　To study the relationsh ip between pylic countercurrent blood-flow and intrahepatic metastasis of hepat ocarcinoma.　Methods　Portal vein-hepatic arter y fistula and pylic countercurrent blood flow in the liver were examined by colo r Doppler ultrasound. Patients examined were divided into four groups: group 1, hepatocarcinoma with background of hepatitis, group 2, hepatocarcinoma without b ackground of hepatitis, group 3, hepatitis and group 4, normal liver.　Results　Pylic countercurrent flood flow was most frequent ly observed in group 1 patients. Intrahepatic metastasis was more frequent in gr oup 1 than in group 2 patients. There was no statistically significant differenc e in the frequency of portal vein-hepatic artery fistula formation around and i nside of tumor between group 1 and group 2 patients. 　Conclusio n　Intrahepatic metastasis of hepatocarcinoma is due to counterc urrent blood flow in the portal system.
