Lung transplantation and posterior reversible encephalopathy syndrome : a case series

Posterior reversible encephalopathy syndrome is a neurological problem characterized by headache, altered mental status, focal neurological deficits, visual disorders, and seizures. The disorder is related to a number of diseases including calcineurin inhibitor therapy in solid organ transplantation. The incidence of posterior reversible encephalopathy syndrome in lung transplantation patients is unclear; probably the majority of the cases are unreported. The authors have described a case series constituted of four patients presenting posterior reversible encephalopathy syndrome after bilateral lung transplantation. The cases had in common complicated surgery and a posttransplant course characterized by hypertension, hypomagnesemia and acidosis. Invasive mechanical ventilation, calcineurin inhibitor discontinuation, aggressive antihypertensive therapy, and electrolyte regulation led to near complete recovery of symptoms
