Figure 2. A tiny HCC resection planned by preoperative simulation and intraoperative navigation. Left upper: A tiny HCC in the subsegment of 8dorsal (yellow arrow) was revealed in arterial phase of contrast computed tomography. Right upper: The area of 8dorsal subsegment (pale blue area, red arrow shows the root of the portal vein) was planned to be resected in preoperative simulation. Left lower: After the transection of 8dorsal subsegment Glissonian pedicle, the planned area of resection (surrounded by red line) was revealed as ischemic area (no-fluorescent area with ICG injection). Right lower: The tumor was resected inside the planned area of resection. HCC: Hepatocellular carcinoma.
