Although there is an agreement that liver grafts from pediatric donors (PDs) should ideally be used for pediatric patients, there remain situations when these grafts are turned down for pediatric recipients and are then offered to adult recipients. The present study aimed to investigate the outcomes of using these grafts for liver transplantation (LT) in adult patients. Data from all patients undergoing LT between 2002 and 2014 were obtained from the United Network for Organ Sharing Standard Analysis and Research file. Adult recipients undergoing LT were divided into 2 groups: those receiving a pediatric liver graft (pediatric‐to‐adult group) and those receiving a liver graft from adult donors (adult‐to‐adult group). A separate subgroup analysis comparing the PDs used for adult recipients and those used for pediatric recipients was also performed. Patient and graft survival were not significantly different between pediatric‐to‐adult and adult‐to‐adult groups ( P  = 0.08 and P  = 0.21, respectively). Hepatic artery thrombosis as the cause for graft loss was higher in the pediatric‐to‐adult group (3.6%) than the adult‐to‐adult group (1.9%; P  < 0.001). A subanalysis looking at the pediatric‐to‐adult group found that patients with a predicted graft‐to‐recipient weight ratio (GRWR) < 0.8 had a higher 90‐day graft loss rate than those with a GRWR ≥ 0.8 (39% versus 9%; P  < 0.001). PDs used for adult recipients had a higher proportion of donors with elevated aspartate aminotransferase/alanine aminotransferase (20% vs. 12%; P  < 0.001), elevated creatinine (11% vs. 4%; P  < 0.001), donation after cardiac death donors (12% vs. 0.9%; P  < 0.001), and were hepatitis B virus core positive (1% vs. 0.3%; P  = 0.002) than PDs used for pediatric recipients. In conclusion, acceptable patient and graft survival can be achieved with the use of pediatric liver grafts in adult recipients, when these grafts have been determined to be inappropriate for usage in the pediatric population.
