Fetal alloimmune thrombocytopenia: is less invasive antenatal management safe?

Objectives: The aim of this study was to review recent multicenter data on antenatal management of anti-HPA-1a fetal alloimmune thrombocytopenia and, based on this retrospective study and on recent literature, to evaluate if FBS modified the obstetrical management.

Material And Methods: This retrospective study in France includes 23 pregnancies in 21 women who had a previous thrombocytopenic infant due to anti HPA-1a alloimmunization. All pregnant women received intravenous immunoglobulin (IVIG) treatment, with or without corticosteroids.
