Graft type in pediatric liver transplantation.

Purpose of review To review the literature on graft type in pediatric liver transplantation, with a specific focus on publications since 2010. Recent findings Due to the limited availability of whole livers for transplantation, the majority of pediatric patients will receive a technical variant graft (live donor, reduced, split). Although the outcomes of these grafts may be inferior to whole organs, the detrimental impact needs to be balanced with the impact of technical variants on improved access and survival to transplantation. Vigilance in detecting and managing posttransplant complications is critical in ensuring the optimal outcome. Infants under 5 kg pose a particular challenge in terms of graft selection with hyperreduced and monosegment grafts proposed for this population. Grafts from donors after cardiac death show promise in expanding the donor pool. However, experience in pediatric patients with these grafts is quite limited, particularly in young children who form the majority of pediatric transplant recipients. Auxiliary transplantation is proposed as a strategy for children presenting with fulminant hepatic failure and for children with metabolic diseases. Summary The majority of children will receive a technical variant graft, with graft choice being largely determined by organ availability.
