[Neurological disorders in liver transplantation].

ABSTRACT

Background and purpose: Liver transplantation is the only curative treatment in patients with end-stage liver failure. It has been associated with neurological disorders more frequently than other solid organ transplantations. We aimed to detect neurological disorders in liver transplantation patients and determine those that affect mortality. Methods: One hundred eighty-five patients, 105 with and 80 without neurological disorders, were included in this study. The follow-up was categorized into three periods preoperative, early postoperative and late postoperative. We analyzed all medical records, including demographic, laboratory, radiological, and clinical data. Results: Neurological disorders were observed in 52 (28.1%) patients in the preoperative period, in 45 (24.3%) in the early postoperative, and in 42 (22.7%) in the late postoperative period. Hepatic encephalopathy in the preoperative and altered mental state in the post-operative period were the most common neurological disorders. Both hepatic encephalopathy (37.5%) and altered mental state (57.7%) caused high mortality (p=0.019 and 0.001) and were determined as indepen-dent risk factors for mortality. Living donor transplantation caused less frequent mental deterioration (p=0.049). The mortality rate (53.8%) was high in patients with seizures (p=0.019). While mortality was 28.6% in Wilson's disease patients with neurological disorders, no death was observed in patients without neurological disorders. Conclusion: We identified a wide variety of neurological disorders in liver transplantation patients. We also demonstrated that serious neurological disorders, including hepatic encephalopathy and seizures, are associated with high morbidity and mortality. Therefore, in order to avoid poor outcomes, hepatic encephalopathy should be considered as a prioritization criterion for liver transplantation.
