    Abstract:
    BACKGROUND/AIMS: Hepatic artery and portal vein thromboses after liver transplantation remain significant causes of graft loss. Doppler ultrasonography is useful for detecting the thrombosis early. Doppler examination requires specialized equipment and training. However the results depend on the skill of the operator. METHODOLOGY: We developed a new Doppler probe that can be implanted in the abdominal cavity. The probe was used for 48 hours in 10 living donor liver transplantation patients. RESULTS: In all recipients, hepatic arterial and portal flows were monitored continuously. The medical staff could easily operate the ultrasonography system at the bedside. CONCLUSIONS: The technique was useful for detecting hepatic blood flow for 48 hours after liver transplantation.
