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

Figure 3 A case of hepatoblastoma evaluated the relationship between the tumor and the major blood vessels of the liver after 5 cycles of neoadjuvant chemotherapy. A and B: Contrast-enhanced computed tomography showed that the tumor was still touching three hepatic veins and the inferior vena cava; C: Three-dimensional imaging based on computed tomography images revealed that the left and middle liver veins merged into the inferior vena cava after the common trunk, with a distance of only 0.5117 mm between the tumor and the common trunk; D and E: Preoperative simulated right hemihepatectomy demonstrated that the future liver remnant volume was sufficient at 34%; F-H: The operation proceeded successfully according to preoperative planning, with careful protection of the common trunk and complete removal of the tumor.
