Retransplantation of the liver after side-to-side caval anastomosis

Caval reconstruction in orthotopic liver transplantation is generally performed by two end-to-end anastomoses, using a portal and caval-axillary bypass to sustain hemodynamic stability. In the piggyback modification, the donor's suprahepatic inferior vena cava (IVC) is anastomosed end-to-side to the recipient's preserved IVC. We have used a recently described variant of the piggyback in 18 patients in whom both IVCs are anastomosed side-to-side. We report two patients who needed three retransplants after this reconstruction and conclude that regrafting can be performed in a quick and safe manner.
