[Autoimmune thrombocytopenia and pregnancy].

Autoimmune thrombocytopenic purpura PTA, occurs more commonly in women during the reproductive years. Consequently, physicians frequently must manage pregnant patients with PTA. The management of the mother is simplified because an important measure of platelet count, is readily available. However the management of the fetus is more difficult because no definitive maternal treatment to prevent fetal thrombocytopenia has been successful. The performance of percutaneous umbilical blood sampling or fetal scalp sampling allow the determination of fetal platelet before delivery. If a fetal thrombocytopenia of less than 50,000 mm3 is detected, cesarean section is indicated to avoid intracranial hemorrhage in the fetus.
