Abstract    Objective    To evaluate the impact of preoperative virtual liver surgery planning on central hepatic resection. Methods    Using the liver surgery planning system software Liv1.0, virtual hepatectomy were performed in 49 cases with centrally located hepatocellular carcinoma. Data were correlated to intraoperative findings. Results    The mean liver volume of 49 cases measured by the software and the real resected was (543±225) mL and (573±212) mL, respectively. The mean error was（29±66）mL. Comparison by means of linear regression analysis between volume measurement and the real resected showed a nearly ideal correlation coefficient ( r =0.983, P＜0.01). Conclusions    The virtual liver surgery planning was helpful in patients with central hepatic resection for (1) determination of resectability and (2) selection of operative strategy.
