title: Factor deficiencies in pregnancy.
abstract: Pregnancy, childbirth, and the puerperium are hemostatically challenging to women with bleeding disorders. This article provides general recommendations for the management of pregnant women with inherited coagulation disorders. Each factor deficiency is discussed, providing an up-to-date review of the literature and, where possible, guidance about how to manage patients throughout pregnancy, delivery, and the puerperium. The factor deficiencies covered are inherited abnormalities of fibrinogen; deficiencies of prothrombin, factor (F)V, FVII, FX, FXI, FXIII; combined deficiencies of FV and FVIII; and the inherited deficiency of vitamin K-dependent clotting factors. The management of carriers of hemophilia A and B is also discussed.
