title: A novel technique for hepatic vein reconstruction during hepatectomy.
abstract: Surgical resection is the treatment of choice for malignant liver tumours. Nevertheless, surgical approach to tumours located close to the confluence of the hepatic veins is a challenging issue. Trisectionectomies are considered the first curative option for treatment of these tumours. However, those procedures are associated with high morbidity and mortality rates primarily due to post-operative liver failure. Thus, maximal preservation of functional liver parenchyma should always be attempted. We describe the isolated resection of Segment 8 for the treatment of a tumour involving the right hepatic vein and in contact with the middle hepatic vein and retrohepatic vena cava with immediate reconstruction of the right hepatic vein with a vascular graft. This is the first time this type of reconstruction was performed, and it allowed to preserve all but one of the hepatic segments with normal venous outflow. This innovative technique is a fast and safe method to reconstruct hepatic veins.
