Quantitative evaluation of hepatic blood flow is possible in liver transplant patients. Here we report quantitative evaluation using pulsed Doppler in living-related partial liver transplantation in an 8-year-old girl with biliary atresia. Despite persistently high serum bilirubin levels resulting from infection by cytomegalovirus, the infection was controlled and bilirubinemia was reduced. We measured hepatic artery (HA) peak systolic velocity (PSV), pulsatility index (PI), portal venous blood velocity (PVV), and left hepatic venous pulsatility index (HVPI). Correlation between HVPI and serum total bilirubin was negative throughout the postoperative course (r=-0.381, p=0.0072), during which HAPSV correlated negatively with PVV (r=-0.557, p
