Neurological Complications after Deceased Donor Liver Transplant: A Case Series from a Public Sector Hospital

Abstract

This is a case series of neurological complications which occurred after Deceased Donor Liver Transplant (DDLT) in a public sector hospital. The clinical presentations were bizarre. This is because patients with End Stage Liver Disease (ESLD) commonly have hepatic encephalopathy and postoperatively can present with similar clinical picture, like tremors and altered mentation. The first patient in the series presented with tremors due to Calcineurin Inhibitor (CNI) toxicity, second had Posterior Reversible Encephalopathy Syndrome (PRES), third with Osmotic Demyelination Syndrome (ODS) with coma and fourth with Extrapyramidal Syndrome (EPS). Patients 1 and 4 had involuntary movements and other clinical manifestations which interfered with recuperation in the postoperative period. So, the dosages of the immunosuppressants were adjusted and serum tacrolimus assay were serially monitored on alternate days. Case 3 developed PRES due to hypertension, as a result of high serum tacrolimus levels. The patient presented with headache and seizures, which if uncontrolled would have been lethal. In Case 4 clinical features and management of a patient who suffered prolonged coma due to ODS for about three months has been discussed. Also, the same patient had a cerebral infarct due to embolic phenomenon inspite of thromboprophylaxis. From this case series, it needs to be emphasised that postoperative occurrence of neurological complications are likely. So careful selection of the recipients, steady titration of immunosuppressants and watchful monitoring of the neurological signs are essential to improve the outcome of the transplant. Imaging of the brain, preferably Magnetic Resonance Imaging (MRI) should not be delayed to rule out other differential diagnosis.
