Computer-assisted three-dimensional individualized extreme liver resection for hepatoblastoma in proximity to the major liver vasculature

Figure 1 The proximity of the tumor to the major liver vasculature in children with hepatoblastoma who received a full course of neoadjuvant chemotherapy. A and E: The distance from the tumor to the inferior vena cava was within 1 cm (V0); B and F: The tumor was touching the inferior vena cava (V1); C and G: The tumor was compressing all intrahepatic veins (V2+P2); D and H: Presence of a tumor thrombus and cavernous transformation of the portal vein (P3).
