Abstract
OBJECTIVE: To study the relationship between pylic countercurrent blood-flow and intrahepatic metastasis of hepatocarcinoma. METHODS: Portal vein-hepatic artery fistula and pylic countercurrent blood flow in the liver were examined by color Doppler ultrasound. Patients examined were divided into four groups: group 1, hepatocarcinoma with background of hepatitis, group 2, hepatocarcinoma without background of hepatitis, group 3, hepatitis and group 4, normal liver. RESULTS: Pylic countercurrent flood flow was most frequently observed in group 1 patients. Intrahepatic metastasis was more frequent in group 1 than in group 2 patients. There was no statistically significant difference in the frequency of portal vein-hepatic artery fistula formation around and inside of tumor between group 1 and group 2 patients. CONCLUSION: Intrahepatic metastasis of hepatocarcinoma is due to countercurrent blood flow in the portal system.
