title: Replacement of the retrohepatic vena cava in segmental liver transplantation.
abstract: Reduced grafts represent an important technical development in paediatric liver transplantation. The use of a left lateral segment graft has required preservation of the native inferior vena cava to "piggy-back" the graft onto it. We report four children who underwent left lateral segment transplantation with caval replacement using the donor iliac vein because the native retrohepatic inferior vena cava was small, friable or difficult to preserve. There were no caval or hepatic vein complications post-transplant and the donor iliac vein proved to be a satisfactory interpositional graft. The technique offers the advantages of a wider retrohepatic cava avoiding venous outflow or caval obstruction, provides good tissue to suture and is well suited for the triangulation technique of the left hepatic vein.
