Surgical approach for hepatitis C virus-related hepatocellular carcinoma

Figure 2 Surgical planning by three-dimensional simulation technique. The three-dimensional liver simulation enables virtual hepatectomy and volume estimation of future liver remnant (FLR). In this case, a large hepatocellular carcinoma is located in segment 7 and 8, and partially extending to dorsal part of segment 5. Right hemihepatectomy is impossible due to very small FLR volume. However, when preserving the territory fed by a thick ventral branch for segment 5 (P5vent) and segment 6, the tumor is resectable leaving sufficient volume of the liver parenchyma. S5vent: Ventral part of segment 5; S5dor: Dorsal part of segment 5; S8vent: Ventral part of segment 8; S8dor: Dorsal part of segment 8.
