[Indications for and techniques of hepatic vein reconstruction in hepatectomy for hepatocellular carcinoma].
The indications for hepatic vein reconstruction (HVR) in resection of segments 7 and 8 for hepatocellular carcinoma (HCC) have been controversial. Although right hepatic vein ligation may not cause complications in some patients, hepatic parenchymal congestion and liver dysfunction occur in others. We performed HVR using autovein grafts in 6 HCC patients, patch grafts in 3, and direct anastomosis in 1, respectively. From this experience, we consider that HVR may be indicated in patients with a discolored hepatic area after hepatic vein ligation, and without inferior right hepatic vein and intrahepatic venous communication. Furthermore, although repeat hepatectomy has resulted in improved survival in patients with recurrent hepatic tumors, when the right hepatic vein has already been ligated, numerous intrahepatic communicating vein anastomoses develop. In repeat hepatectomy in such patients, uncontrollable massive bleeding from hepatic veins occurs. Therefore, HVR is recommended to maintain the previous hepatic vein anatomy. Recently, the indications for HVR have been studied to prevent hepatic vein congestion and liver dysfunction in both the remant and graft livers in living-related donor partial liver transplantation from the standpoint of hemodynamics. Additionally, the technique of direct hepatic vein anastomosis is presented.
