Aim: Liver transplantation (LT) has been used as a definitive management for children with end-stage liver disease or acute liver failure. Living-donor LT (LDLT) has been a common type of LT performed in Asian countries, including Japan, where deceased donors are rarely available. However, the neurological complications (NCs) associated with LDLT remain unknown. The purpose of this study was to clarify the characteristics of NCs in children after LDLT.
Methods: This study is a retrospective observational study carried out at a tertiary children's hospital in Japan. We studied children who had undergone LDLT between January 2001 and January 2020.
Results: We examined 602 cases of LT, of which 559 were LDLT cases (92.9%). NCs after LT were present in 21 cases (3.8%). The most common neurological symptoms were seizure (n = 17), whereas disturbance of consciousness without seizure was observed in four cases. The frequency of NCs for each of the indications was 12.2% for fulminant hepatic failure, 6.5% for metabolic liver disease, and 0.7% for cholestatic liver disease.
Interpretation: We report the characteristics of NCs after LDLT in children. The frequency of NCs after LT was high in cases of fulminant hepatic failure and metabolic diseases, who might have had neurological symptoms or impaired consciousness before LT.
