case_images: Preoperative CT images of case 1: unenhanced phase (A), arterial phase (B), and venous phase (C); preoperative CT images of case 2: unenhanced phase (D), arterial phase (E), and venous phase (F); preoperative CT images of case 3: unenhanced phase (G), arterial phase (H), and venous phase (I); inside the yellow circle is the portal vein tumor thrombus.

case_images: The enhanced CT scans suggested the following: diffuse right liver cancer with tumor thrombus formation in the main portal vein (MPV) and left and right branches; the tumor was mainly located in the right lobe and had a maximum size of 8.8 cm; and liver cirrhosis with portal hypertension (Figures 1G-I).

case_images: The RPV distant to the bifurcation, the left portal vein (LPV), and the MPV located distal to the PVTT were occluded by vascular clip (Figure 2G). The PVTT in the RPV or MPV was then removed from the opening, and the possible residual tumor thrombus was flushed with portal blood flow by releasing the vaso-occlusive band of the MPV (Figure 2H). The right branch of the portal vein was disconnected, and the broken end was ligated (Figures 2I,J). The liver was split into the root of the proximal middle hepatic vein and in front of the inferior vena cava (Figure 2K). A brief operation diagram is shown in Figures 2A-F.
