Right Anterior Segmentectomy (V, VIII) and VII Segmentectomy Combined with Resection of the Right Hepatic Vein by Preserving the Right Inferior Hepatic Vein

The main indication for right anterior hepatic lobectomy preserving major hepatic veins is hepatocellular carcinoma (HCC) localized in the anterior segment. In cases where the tumor extends to segment VII, the right hepatic vein is unable to be preserved and right hepatic lobectomy is then needed. However, in patients in whom an inferior right hepatic vein (IRHV) can be demonstrated preoperatively, segment VI can be preserved. This operation is effective for postoperative functional reserve and complete resection of the affected segment.
