Congenital coagulopathies and pregnancy: report of four pregnancies in a factor X-deficient woman.

Abstract

Pregnancy in women with congenital coagulation factor deficiencies has been associated with adverse fetal outcomes. Recurrent spontaneous abortions, placental abruptions, and premature births are reported, the exact reasons for which are not clear, and management of such patients continues to be a challenge. We reviewed the outcome of four pregnancies in a patient with factor X deficiency, and looked at the effect of factor replacement therapy on pregnancy. Her first two pregnancies resulted in the birth of extremely premature babies at 21 and 25 weeks of gestation, both of which died in the neonatal period. The patient was treated with fresh frozen plasma for acute bleeding episodes during these pregnancies. In addition during her second conception she was given factor IX complex [Konyne] prophylactically, but only in the latter half of her pregnancy. During her next two pregnancies she was treated early on during pregnancy, with prophylactic replacement of factor X. She delivered healthy babies at 34 and 32 weeks of gestation, and they are both doing well. We therefore suggest possible mechanisms by which aggressive prophylactic factor support in a female with severe congenital coagulopathy, may improve on fetal outcome.
