Domino as a bridge to definitive liver transplantation in a neonate.

An interim liver transplant was used to extend survival in a neonate. This was accomplished by the initial transplant of a left-lateral segment of a metabolically abnormal liver obtained from a 7-yr-old patient with primary oxalosis. This bridging strategy was required because our neonatal patient was dying of fulminant hepatic failure caused by hepatic vein thrombosis and a small liver or liver segment could not be found. Although problems with hyperoxaluria were encountered in the neonate post-transplant, the interim liver transplant enabled the baby to survive and grow until the age of 4 months. At that time, a definitive transplant was performed using the left-lateral segment of his mother's liver. This case represents the first reported use of a pediatric domino transplant where a metabolically abnormal liver was used to allow sufficient growth to permit a definitive liver transplantation.
