Thrombopénie sévère chez un nouveau né de mère splénectomisé pour purpura thrombopénique idiopathique: Severe thrombopenia in an infant born to mother splenectomized for idiopathic thrombopenic purpura

Neonatal thrombopenia is the most common hemostatic abnormality in newborns. It is defined as a platelet count below 150.000/mm(3). 40% of newborns to mothers with a history of autoimmune thrombopenia are at risk of developing neonatal thrombopenia while 10-15% of them are at risk of developing severe thrombopenia. We here report the case of a 20 days old newborn to mother splenectomized for idiopathic thrombopenic purpura in order to highlight the relationship between the severity of maternal disease and the severity of the neonatal thrombopenia and thereby to avoid the risk of intracranial hemorrhage resulting in death or neurological sequelae.
