Hepatic transplantation in children using reduced size allografts.

The shortage of paediatric liver donors has led to the use of reduced size hepatic allografts. Between July 1987 and July 1990, 30 reduced size orthotopic liver transplantations were performed in 24 children aged between 3 months and 7 years. All patients were in advanced chronic or acute liver failure and were considered unlikely to survive for long enough for a size-matched donor to become available. The most common indication was biliary atresia. The median intraoperative blood loss was 75 (range 13-1015) ml kg-1. Nine patients have died and seven have undergone retransplantation, four successfully. Seven patients had portal vein hypoplasia with a high graft failure rate due to ischaemic infarction. There was significant morbidity from biliary tract complications, leading to further operations in four cases. The 1-year actuarial survival rate was 62 per cent.
