Acquired haemophilia A diagnosed during pregnancy

Pregnancy-associated haemophilia A is an uncommon, acquired bleeding disorder which usually presents post-partum; very rarely it may present during pregnancy. No consensus guidelines exist on the management of this condition in pregnancy and very few cases have been reported in the literature. Here we describe the case of a woman presenting with acquired haemophilia A during pregnancy and outline the management of her bleeding disorder. We contrast her case with that of two other women, presenting to the same tertiary referral centre, with acquired haemophilia A presenting post-partum. These cases highlight the heterogeneous management of this condition and how it may be successfully managed in pregnancy.
