Topological approach of liver segmentation based on 3D visualization technology in surgical planning for split liver transplantation

Figure 2 Based on the Couinaud liver segmentation method, left-lateral segment and right tri-segment splits were performed. During the operation, obvious ischemic changes in the cross-section of the right tri-segment were observed. A: The right tri-segment graft; B: The left-lateral segment graft; C: Cleaved right tri-segment with distinct ischemia in the hepatic segment after hepatic reflow (white arrow).
