title: Pregnancy in women with congenital factor VII deficiency.
abstract: The aim was to review the pregnancy and obstetric outcome in women with factor VII (FVII) deficiency. The study group contained women with FVII deficiency, registered with Haemophilia centre and Haemostasis Unit at the Royal Free Hospital, London. The women were interviewed and case notes were reviewed. The main outcome measures were changes in FVII levels in pregnancy, maternal and perinatal outcome. The FVII levels ranged from 7-36 IU dL(-1) in the 13 women included in the study. There were a total of 14 pregnancies in seven women. Ten pregnancies in four women were prior to the diagnosis of FVII deficiency. Following the diagnosis of FVII deficiency, there were four pregnancies in three women. There was an increase in the FVII level during pregnancy in these women from a mean baseline level of 33 IU dL(-1) to a mean of 73 IU dL(-1). These women received recombinant FVIIa replacement during labour and delivery. There were two early pregnancy losses, both associated with excessive haemorrhage. There was only one postpartum haemorrhage in the study. There is a significant increase in FVII levels in pregnancy in women with heterozygous FVII deficiency. The risk of bleeding in early pregnancy might be higher than that at term, due to inadequate rise in the FVII level in early pregnancy.
