BACKGROUND/AIMS: To understand the three-dimensional relationship between the liver vasculature and tumor by intraoperative sonography, some training is inevitable. Three-dimensional ultrasound has been evaluated in various fields, but not yet in intraoperative sonography. METHODOLOGY: Extracorporeal 3-D ultrasonography was performed in 32 patients. Of these, 20 underwent intraoperative 3-D ultrasonography. Using these images, we evaluated whether or not the portal vein, hepatic vein and its branches were discernible. RESULTS: Satisfactory images were obtained in all 32 patients by extracorporeal methods and in 15 by intraoperative 3-D ultrasonography. The number of visualized veins, including the right portal vein, its anterior branch, posterior branch, anterior superior branch, anterior inferior branch and right hepatic vein, was 32, 32, 23, 28, 22, and 30 by extracorporeal 3-D ultrasonography, and 15, 14, 10, 8, 5, and 12 by intraoperative 3-D ultrasonography. The relationships between the intrahepatic artery, portal vein, and hepatic vein were more clearly visualized by intraoperative 3-D sonography. CONCLUSIONS: Intraoperative 3-D ultrasonography clearly showed small branches of the liver vasculature and their 3-D relation, which may be helpful for liver surgery. However, this method requires further improvement.
