medical management often futile,Liver transplantation only“cure”,5.7%OLT for FLF,Shortage of donor organ,Death or complications often intervene,Liver Transplantation Fulminant Liver Failure,Recurrence of Disease After LT,Increasing problem as patients live longer after LT,Some recurrent disease inconsequential,whereas other recurrence a cause of death or re-LT,Potential requirement for re-LT an added burden to already limited resources for LT,Results of re-LT inferior to initial LT(survival:62%vs 87%at 1 yr and 54%vs 77%at 3 yrs,respectively),1,1,.UNOS Update:UNOS Scientific
