Management of pregnancy and delivery in women with inherited bleeding disorders.

Women with inherited bleeding disorders present a wide spectrum of clinical symptoms that vary from mild or moderate bleeding tendency to severe episodes. Monthly haemostatic changes affect these women during menstruation and ovulation. These events may be associated with significant bleeding and pain leading to the limitations in conducting daily activities and adverse effect on quality of life. Likewise, pregnancy and delivery are critical times for affected women. During pregnancy, they may be at greater risk of miscarriage and bleeding complications. In particular, recurrent miscarriage was observed in women with type 3 von Willebrand disease, afibrinogenaemia and severe factor XIII deficiency, and an optimal therapeutic plan is required during their pregnancy. Precautions must be taken at delivery in these women, since they could be at risk of bleeding. The lack of adequate information makes it very difficult to prepare evidence-based guidelines for the prevention of bleedings in affected women and their treatment. A multidisciplinary team of obstetricians, haematologists and paediatricians is required with a good knowledge of these disorders and an awareness of the potential maternal neonatal complications.
