title: Protein S deficiency and pregnancy: is there a case for ylaxis?
abstract: Pregnancy reduces protein S to 40-50% of normal levels, but it is not clear whether lower protein S levels raise the risk of developing thrombo-embolism during pregnancy. This case report describes a primigravida with a documented protein S deficiency who delivered at 38 weeks of gestation with no thrombo-embolic complications.
