ABSTRACT Objective:To detect the portal vein cancerous thrombosis and the arterial flow of primary hepatic carcinoma(PHC) secondary to liver cirrhosis.Method:108 cases were studied by color Doppler ultrasound.They divided into three groups:54 PHC (group 1),27 PHC with portal vein thrombosis (group 2)and 27 PHC with liver cirrhosis (group 3).Results:The mean peak systolic velocity(PSV) of group 2 was higher than those of group 1 and group 3,the mean resistance index(RI) of group 3 was higher than those of group 1 and group 2.There were statistical differences for the mean PSV and the mean RI among groups when tumors were smaller than or equal to 10cm in diameter.Conclusion:The PSV and RI of artery flow of PHC were significantly affected by portal vein cancerous thrombosis and liver cirrhosis.
