We report a first pediatric liver transplantation from a brain-dead donor under 6-year-old in Japan. A 9-month-old girl suffered from graft failure after living donor liver transplantation for biliary atresia. The deceased donor liver transplantation (DDLT) from under 6-year-old was performed. It was important to select appropriate surgical devices for the pediatric organ recovery based on the preoperative evaluation. Sufficient vessel grafts were procured because of difficult vascular reconstruction. She discharged on 172 days after DDLT. There have been few cases of pediatric organ donation in Japan. Therefore we should make careful preparation for both of donor and recipient.
