Abstract Management and, particularly, mode of delivery of the pregnant patient with immune thrombocytopenic purpura (ITP) are controversial. We reviewed our experience with 31 pregnancies in 25 women with ITP over a 10-year period. Fourteen infants were born vaginally and 18 by cesarean. Six major complications occurred among mothers delivered by cesarean, whereas none occurred among those born vaginally (P = .028). Three of 32 infants were born with moderate thrombocytopenia (platelet count 51-100 x 10(9)/L) and two with severe thrombocytopenia (platelet count 50 x 10(9)/L or less); there were no clinically significant complications in these infants. No maternal characteristic could be used to predict the neonatal platelet count. In an analysis of 474 infants of mothers with ITP reported in the literature and including the present series, 10\% were born with moderate thrombocytopenia and 15\% with severe thrombocytopenia. The overall rate of intracranial hemorrhage in newborns with moderate or severe thrombocytopenia was 3\%. No significant association was found between the rate of intracranial hemorrhage and delivery mode for moderately and severely thrombocytopenic neonates together (weighted odds ratio 1.69, 95\% confidence interval 0.14-44.6) or for those with severe thrombocytopenia (crude odds ratio 1.38, 95\% confidence interval 0.07-84.67). We conclude that the mode of delivery may not affect the rate of intracranial hemorrhage in thrombocytopenic newborns.
