Abstract
To report the authors' experience with hepatic vein reconstruction and plasty in living donor liver transplantation for adult patients. A right liver graft without the middle hepatic vein (MHV) trunk (modified right liver graft) can cause severe congestion of the right paramedian sector. However, the need for MHV reconstruction has not been fully recognized. From June 2000 to December 2001, 30 adult patients received a modified right liver graft. Major MHV tributaries were preserved and reconstructed under the authors' criteria. Plasty of recipient hepatic veins for a wide outflow orifice was performed when necessitated. The regeneration of paramedian and lateral sectors of the grafts was examined by computed tomography 1 and 3 months after the operation. MHV tributaries were reconstructed in 18 grafts. Plasty of recipient hepatic veins was performed in 15 patients. All patients survived the operation. The regeneration of paramedian and lateral sectors was equivalent. A modified right liver graft can provide satisfactory surgical results if hepatic vein reconstruction and plasty are performed using the present techniques.
