[Management of thrombocytopenia during pregnancy]

Abstract

Thrombocytopenia defined as a platelet count < 150 G/l is found in about 10% of pregnancies. The differential diagnosis is similar to that of non-pregnant women but some specific causes related to pregnancy need to be considered. Even if the so-called gestational thrombocytopenia is the most common etiology, a careful history and simple laboratory tests are needed in order not to miss a serious condition that may require specific and sometimes urgent treatment. However in most cases detailed investigations are not required during pregnancy and a pragmatic attitude can be proposed, including monitoring of platelet count in the mother and platelet count in the newborn.
