Figure 4. The HV-root at first one-way parenchymal resection during segmentectomy VIII. (A) the root and anterior wall of the middle hepatic vein (MHV) and a tributary V8 are exposed by HV-root at first parenchymal dissection using monopolar scissors (by the right hand) and bipolar fenestrated forceps (by the left hand); (B) in the middle of the cranial-to-caudal parenchymal dissection, the G-VIII, which was already controlled during hilar preparation, is divided; (C) the root of the right hepatic vein (RHV) is exposed cranially. The divided stump of the G-VIII is shown; (D) the final operative view after completion of a robotic anatomic segmentectomy VIII. The inferior vena cava (IVC) and cranial parts of the MHV and RHV are exposed. The divided stump of G-VIII is also seen
