Neurologic complications in liver transplantation.
A retrospective review is presented of neurologic complications in our first 143 consecutive adult patients (208 liver transplants in 143 adults and 18 children) undergoing liver transplantation. Nineteen (13.2%) of the 143 patients developed neurologic complications in the postoperative period. Immunosuppression was initiated intraoperatively with steroids with the addition of azathioprine on Day 1 and cyclosporine, adjusted by RIA to a level of 400-600 ng/ml, on Day 2 post-transplantation. Azathioprine is discontinued in the third month. Fourteen of the 19 patients (73.6%) presented with CNS complications characterized by: diffuse multifactorial encephalopathy (5 patients); leukoencephalopathy (2 patients) which required temporary (1 case) or permanent (1 case) discontinuation of cyclosporine A; hemorrhage (in 2 cases due to arterial hypertension and coagulopathy and another due to unknown causes); ischemic/anoxic injury secondary to cardiorespiratory arrest (2 patients) or arteriothrombosis (1 patient); and myelopathy (1 patient) due to vertebral compression (T10-T11) secondary to osteoporosis. The diagnostic studies most often employed were computed tomographic (CT) (85.7%) and electroencephalography (EEG) (42.8%). Five of 19 patients (26.3%) suffered peripheral nervous system (PNS) complications: 1 patient with reversible Claude-Bernard-Horner Syndrome caused by central venous catheterization during anesthesia; 2 patients with peroneal nerve palsy due to compression below the knees by operating room table supports; 1 patient with an irreversible lesion of the right recurrent laryngeal nerve secondary to prolonged intubation and central venous catheterization; and 1 patient with a reversible lesion of the left brachial plexus secondary to inadvertant hyperextension of the upper extremity on the O.R. table due to the need for dialysis and catheterization of the axillary vein for veno-venous bypass.(ABSTRACT TRUNCATED AT 250 WORDS)
