Abstract
BACKGROUND: Combined deficiency of vitamin K-dependent coagulation factors (II, VII, IX, X) is an uncommon challenge for the expectant gravida. CASE: A 34-year-old primigravida had congenital combined deficiency of factors II, VII, IX, and X that were incompletely sensitive to vitamin K. She had an altered form of vitamin K-dependent factors that retained immunologic activity but lacked coagulant activity and the normal complement of gamma-carboxyglutamic acid residues. She required vitamin K supplementation throughout her life. After an uneventful pregnancy she had postpartum hemorrhage resulting from an episiotomy. Fresh frozen plasma was administered to achieve hemostasis. The remainder of her postpartum course was normal. CONCLUSION: Combined congenital deficiency of factors II, VII, IX, and X can be managed in pregnancy with the use of vitamin K and fresh frozen plasma.
