Current Approaches to the Evaluation and Management of the Fetus and Neonate with Immune Thrombocytopenia

Fetal and neonatal alloimmune thrombocytopenia is not a well-known disease, except among specialists in maternal–fetal medicine, neonatologists, and certain pediatricians (ie, hematologists). However, this is by far the most common cause of early severe thrombocytopenia in neonates and of intracranial hemorrhage in term neonates. In addition, if a newborn is affected with alloimmune thrombocytopenia, the next child in the family will likely be more severely affected. Thus, the accurate diagnosis and appropriate management of this disorder are of extreme importance in perinatal medicine and will constitute the focus of this review.
