Neurologic complications in adult living donor liver transplant recipients

Background: Neurologic complications (NC) after liver transplantation are not uncommon, with serious complications such as central pontine myelinolysis (CPM), often causing disability. Objective: We investigated the incidence and features of NC following liver transplantation in adult recipients. Patients and methods: We retrospectively reviewed the medical records of 319 adult patients who underwent liver transplantation between January 2004 and May 2005 at the Asan Medical Center. Results: Neurologic complications developed in 49 of 319 patients (15.4%). Although most of these complications were minor, including tremor and foot drop, three patients developed CPM, and one each developed posterior leukoencephalopathy, cerebral hemorrhage, and cerebral infarction. One-yr survival rates were 95.9% in patients without NC and 83.7% in patients with NC (p = 0.004). Hospital stay was prolonged in patients with NC. Graft-to-recipient body weight ratio (GRWR) did not affect occurrence of NC. Conclusions: Neurologic complications were not uncommon in liver transplant recipients. These complications contributed to prolongation of hospital stay, increased in-hospital mortality, and decreased graft and patient survival. Every effort should be made to prevent NC, as well as to detect and treat them as soon as possible.
