    AbstractAn extended hepatectomy combined with preoperative portal venous embolization can offer curative resection in patients with initially unresectable hepatocellular carcinoma. However, hypertrophy of the future remnant liver is occasionally unsatisfactory after portal venous embolization in some patients to remove the initially unresectable tumor. In these patients, hepatic venous reconstruction to preserve hepatic parenchyma may contribute to the possibility of resection. The present case report shows a patient with an initially unresectable huge hepatocellular carcinoma in whom transarterial chemoembolization, portal vein embolization, and an extended right hepatectomy combined with distal middle hepatic venous reconstruction were performed to preserve Segment 4 inferior. The patient was a 66-year-old male. He presented with a huge hepatocellular carcinoma located at Segment 8, 7 and 4 superior, but the volume of the left lateral segment was only 267 mL. Transarterial chemoembolization was performed twice and right portal vein embolization was performed once, but the volume of the left lateral segment was only 318 mL compared to 487 mL which was a limit of future remnant liver volume. We therefore performed an extended right hepatectomy combined with distal middle hepatic venous reconstruction to preserve Segment 4 inferior. The left saphenous venous graft was used for this hepatic venous reconstruction. His postoperative course was almost uneventful. Postoperative abdominal computed tomography showed the satisfactorily preserved Segment 4 inferior. Distal hepatic venous reconstruction combined with an extended hepatectomy may further offer a chance of a curative resection for patients in whom enough hypertrophy of the future remnant liver is not obtained after portal venous embolization.
