Abstract;Peripheral liver blood flow has not been investigated using color Doppler ultrasound. The aims of this study were to use color Doppler ultrasound to detect peripheral liver blood flow and to assess the significance of these findings. Blood flow signals near the liver surface (up to 2 cm deep) were investigated using color Doppler ultrasound (7.5 MHz linear type probe). Portal blood flow volume and mean velocity of the right anterior portal venous branch were calculated using pulse Doppler ultrasound (3.75 MHz convex type probe) in 184 consecutive patients (65 with liver cirrhosis (LC), 96 with chronic hepatitis (CH), 23 with fatty liver (FL)) and 15 normal controls (NC). Peripheral blood flow signal density was classified as either abundant, moderate or scanty. Peripheral blood flow could be seen in all patients. In 38 of the 65 (58.5%) patients with LC, the blood flow signal density was higher than the controls. However, in 17 (26.1%) of the LC patients and in all patients with FL, the blood flow signal density was lower than controls. Peripheral blood flow signal density correlated with right anterior portal venous branch flow: increasing volume and velocity in the branch was associated with higher signal density in the periphery of the liver. The results suggest that peripheral liver blood flow can be assessed by color Doppler ultrasound and that ultrasound detection of the blood flow may contribute to evaluating changes in portal venous flow in the periphery of the liver during the progression of liver disease.
