An assessment was made as to the changes in morphology and hemodynamics of the hepatic artery, as well as the superficial hepatic image, over time in chronic viral hepatic disease. The subjects were 33 cases of chronic viral hepatitic disease diagnosed by laparoscopy and 14 cases in a control group not associated with hepatic disorder, totaling 47. As for morphological change, it was observed that the 4th-6th rami exhibited gradual corkscrew changes, and that the rates of change occurring in the withered branch along with the superficial hepatic image over time and the actually measured value as well as the theoretical value of the bifurcating angle between the superior and inferior rami diverging from the anterior branch of the right hepatic artery dissociated gradually. Moreover the diameter of the proper hepatic artery supplying the liver increased along with the superficial hepatic image over time. Hepatic blood flow was maintained or increased along with the superficial hepatic image over time developed morphology wherein energy efficiency decreased gradually. Regarding the change of hemodynamics, the maximum flow rate increased along with the superficial hepatic image over time. Assessment made using ICG proved that the initial time and peak time became early and peak value increased along with the superficial hepatic image over time. The flow rate in the hepatic artery increased and the arterial flow amount into the liver increased, but as increases of A-V shunt, etc. were assumed, it was considered that the effective hepatic flow rate did not increase as much as hepatic arterial flow rate.
