Advances in TransplantationLiver transplantationPediatric Donor to Adult Recipients in Donation After Cardiac Death Liver Transplantation: A Single-Center Experience

- Adults undergoing DCD liver transplantation who receive a graft from a donor younger than or equal to 13 years (pediatric donor) have similar outcomes to recipients of organs from older than 18-year-old donors.
- The EAD, SFSS, and HAT rates were acceptable in pediatric donors to adult recipients.
- 0.7% < GRWR <0.8% was usable for pediatric donors to adult recipients and had the same prognosis with GRWR >0.8%.

BackgroundThe impact of using liver allografts from donors who are younger than 14 years at the time of donation after cardiac death (DCD) liver transplantation in terms of early allograft dysfunction (EAD) and graft survival is undefined. To determine if adults undergoing DCD liver transplantation who receive a graft from a donor age younger than or equal to 13 years have similar outcomes to recipients of organs from older than 18-year-old donors.MethodsRecords from adult patients undergoing DCD liver transplantation between March 2012 and December 2015 who received whole grafts from donors after cardiac death were reviewed. Patients with donors younger than or equal to 13 years (group 1) and older than 18 years (group 2) were compared for EAD rates, hepatic artery thrombosis (HAT), and graft survival.ResultsRecords of 60 DCD liver transplantation patients were analyzed. The 90-day and 1-year graft survival rate of both groups was 90% versus 96% (P = .427) and 80% versus 84% (P = .668), respectively. The EAD rates of groups 1 and 2 were 30% versus 34% (P = .806). The incidence of HAT was 20% in group 1 compared with 12% in group 2 (P = .610). Also, 0.7% < graft to recipient weight ratio (GRWR) <0.8% was also usable for pediatric donor to adult recipients.ConclusionsWhole liver grafts from donors younger than or equal to 13 years can potentially be used in selected size-matched (GRWR >0.7%) DCD adult recipients.
