Critical use of extended criteria donor liver grafts in adult-to-adult whole liver transplantation: a single-center experience.
This study presents our experience with the use of extended criteria donor (ECD) liver grafts. One hundred fifteen liver transplants were divided into 2 groups: standard (S) and nonstandard (NS). Fifty-eight patients in group S received a liver procured from an ideal donor, whereas 57 patients in group NS received an organ from an ECD. On the basis of the number of risk factors, patients were divided into 3 subgroups: the S group with 58 receiving a standard graft, the NS1 group with 44 receiving a graft with 1 or 2 risk factors, and the NS2 group with 13 receiving a graft with 3 to 4 risk factors. Patient survival was not different at 6, 12, and 24 months (P > 0.05), whereas graft survival was different (P = 0.0079). Both patient survival and graft survival were influenced by the cumulative number of risk factors. The univariate analysis of the donor risk factors detected hemodynamic factors as predictive of graft failure (P = 0.024) and death (P = 0.018). In the multivariate analysis, which was adjusted for recipient age and donor and recipient gender, hemodynamic risk factors and Model for End-Stage Liver. Disease score in the recipient were the only variables independently associated with graft failure (P = 0.006, P = 0.012, negatively). Finally, we observed a reduction of dropout from the list to 9% from 14.1% (P = 0.04) and of mortality on the list to 32.55% from 41.01% (P = 0.11). Critical use of ECD liver grafts allowed recipients in the waiting list to have a greater chance of being transplanted.
