Triple Positive Antiphospholipid Antibody Syndrome in Pregnancy with High Frequency Plasma Exchange: A Case Report.

ABSTRACT

Introduction: Triple antibody positive antiphospholipid syndrome during pregnancy carries a poor prognosis. The placental vasculature is particularly vulnerable to these antibodies resulting in a marked increased risk of fetal growth restriction, placental infarction, abruption, stillbirth, and preterm severe preeclampsia. Case Presentation We report a case of a primigravida with triple antibody positive antiphospholipid syndrome that demonstrated placental insufficiency and fetal compromise at a previable gestation. The patient underwent plasma exchange every 48 h for 11 weeks resulting in delivery of a viable infant. Placental blood flow was improved after complete absence of end-diastolic flow in the fetal umbilical artery. Conclusion: Scheduled plasmapheresis every 48 h can be considered in select cases of antiphospholipid antibody syndrome.
