Surgical approach for hepatitis C virus-related hepatocellular carcinoma

Figure 1 Concept of anatomic resection of the liver. This schema shows an example of resection for hepatocellular carcinoma located in ventral part of Segment VIII. The line A-A’ indicates non-anatomic limited resection with adequate surgical margin and the line B-B’ represents anatomic resection of ventral part of Segment VIII. Because the “tumor-bearing” portal territory is at high risk of harboring micrometastases scattered via portal veins, systematic removal of the corresponding portal region would offer higher chance of eradicating cancer cells. T: Tumor; P8v: Ventral branch of Segment VIII portal pedicle; P8d: Dorsal branch of Segment VIII portal pedicle; MHV: Middle hepatic vein; V8i: Intermediate vein for Segment VIII.
