Figure 4. Exposure of landmark hepatic veins after parenchymal dissection during anatomic (sug)segmentectomy. (A) Image after completion of laparoscopic anatomic segmentectomy 2. Left hepatic vein (LHV) and venous tributaries from Sg3 (V3) are exposed. The resected stump of Glissonian pedicle to Sg2 (G2, arrow) is shown beneath LHV; (B) image after completion of laparoscopic anatomic segmentectomy 8. The resected stump of G8, preserved G5 and G-ant, stump of V8 and the right (RHV) and middle (MHV) hepatic veins are exposed on the liver cutting surface; (C) image after completion of laparoscopic anatomic segmentectomy 7 in the left semi-prone patient position. Inferior vena cava (IVC), RHV, inferior RHV (IRHV, arrow) and the resected stump of G7 are exposed; (D) image after completion of robotic anatomic subsegmentectomy 8b. The resected stump of G8b (arrow), RHV and its venous tributaries (V8 and V6) are exposed on the liver cutting surface.
