Hepatic venous reconstruction in left-sided hepatectomy combined with caudate lobectomy

A female patient aged 61 years was diag-nosed with metastatic liver cancer from colorectal cancer. Com-puted tomography (CT) scanning showed that the mass was located at the confluence of 3 hepatic venous trunks and had a diameter of 7 cm. The patient's standard liver volume was 1087 ml, and the volume in the right lobe was 634 mL and the right posterior lobe was 279 ml. We attempted to resect the left and caudate lobes with the middle hepatic vein (MHV) and to reconstruct tributaries of the MHV from segment V using a cryo-preserved autologous iliac artery. The operation time was 280 minutes and blood loss was 300 mL, and no postoperative com-plications were observed. The length of hospital stay was six days. Two weeks after the operation, imaging examinations by ultrasound and CT indicated that the graft vessel was patent. Three months after the operation, ultrasound examination demonstrated that the bypass was blocked, while no atrophy in hepatic segment V was detected, which indicated that communi-cating branches between the hepatic veins of segment V and the right hepatic veins had formed. Hepatectomy combined with hepatic venous reconstruction is safe and feasible for hepatoma at the confluence of three hepatic venous trunks.
