A case of post-operative posterior reversible encephalopathy syndrome in children: A preventable neurological catastrophe.

Abstract

Posterior reversible encephalopathy syndrome (PRES) is a clinic-radiological syndrome that is generally reversible and may lead to permanent neurological damage if left untreated. PRES has been commonly linked with hypertension along with associated vasogenic oedema. Children are more susceptible to these perturbations due to the narrow range of cerebral autoregulation. PRES must be considered in differentials of any neurological dysfunction which is associated with hypertension in the immediate post-operative period. Inadequate pain control in the post-operative period may cause hypertension that may lead to subsequent PRES. We report a case of postoperative PRES in a 12-year-old previously normotensive child posted for splenectomy with an acute rise in blood pressure in the post-operative period.
