Antiphospholipid syndrome (APS) in women refers to a syndrome characterized by both:

Arterial or venous thrombosis or specific pregnancy complications, and

Laboratory evidence of antibodies to proteins bound to anionic phospholipids

The three main types of antiphospholipid antibodies (aPL) of concern to obstetricians are lupus anticoagulants (LA), anticardiolipin antibodies (aCL) [1], and anti-beta-2-glycoprotein-1 antibodies [2]. Other antibody specificities have been proposed, but have not proven to be predictive in clinical studies.

This topic will discuss pregnancy complications and management in women with APS. General issues related to APS in the nonpregnant population are reviewed separately:
