Intracranial hemorrhage at the onset of thrombotic thrombocytopenic purpura in an infant: therapeutic approach and intensive care management.

Thrombotic thrombocytopenic purpura (TTP) is quite rare in infancy and must be treated intensively as a life-threatening disease. Diffuse vascular thromboses may occur, and neurologic involvement is a cornerstone of the diagnosis of TTP. We describe a case of an infant who presented with a sudden cerebral hemorrhage and subsequently developed the typical clinical features of TTP. Emergency treatment in the Pediatric Intensive Care Unit (PICU) consisted of plasma therapy and exchange-transfusion (EXT) to arrest the intravascular process and the exsanguinating blood loss. Exchange-transfusion is a life-saving procedure that is rarely performed after the neonatal age.
