Segmental liver transplantation from non-heart beating donors--an early experience with implications for the future.

摘要

We report our experience of pediatric liver transplantation with partial grafts from non-heart beating donors (NHBD). Controlled donors less than 40 years of age with a warm ischemia time (WI) of less than 30 min were considered for pediatric recipients. Death was declared 5 min after asystole. A super-rapid recovery technique with aortic and portal perfusion was utilized. Mean donor age was 29 years and WI 14.6 min (range 11-18). Seven children, mean age 4.9 years (0.7-11), median weight 20 kg (8.4-53) received NHBD segmental liver grafts. Diagnoses included seronegative hepatitis, neonatal sclerosing cholangitis, familial intrahepatic cholestasis, hepatoblastoma, primary hyperoxaluria and factor VII deficiency (n=2).The grafts included four reduced and one split left lateral segments, one left lobe and one right auxiliary graft. Mean cold ischemia was 7.3 h (6.2-8.8). Complications included one pleural effusion and one biliary collection drained percutaneously. At 20 months (10-36) follow-up all children are alive and well with functioning grafts. Donation after cardiac death is a significant source of liver grafts for adults and children with careful donor selection and short cold ischemic times.
