Abstract
We reviewed the clinical histories and autopsy records of 35 pediatric patients (ranging in age from 9 months to 18 years) who underwent orthotopic liver transplantation using ciclosporin and corticosteroids for immunosuppression. At the time of death, 19 children (54%) had encephalopathy, 16 (46%) were lethargic or in coma, 10 (29%) had seizures, and 10 were normal. Neuropathological lesions were found on postmortem examination inall 35 patients. Vascular lesions such as infarction, ischemia, thrombosis, and hemorrhage were the most commonneuropathological findings (86%) followed by infectious processes (29%). Candida albicans (2 patients) and Aspergillusfumigatus (3 patients) were the only offending organisms identified, both causing meningoencephalitis. Alzheimer type II astrocytes, a characteristic feature of chronic liver disease, were the singlemost common autopsyfinding (69%). Central pontine myelinolysis was seen in 3 children and basilar artery thrombosis affected 1 child.Neurological complications and their subsequent neuropathology are a significant cause of morbidity and mortality after pediatric liver transplantation. Vascular insults, electrolyte abnormalities, and infections that involve thecentral nervous system are directly related to liver function and the immunosuppression necessary to maintain graftviability. Only with continued observation after surgery combined with rapid medical and surgical treatment can we hope to improve the prognosis following liver transplantation in the pediatric population.
