RESUMEN
To determine changes in Factor VIII (FVIII) and von Willebrand Factor (VWF) in the first 3 days of the puerperium. A prospective study assessing FVIII clotting activity, VWF activity and antigen levels in 95 women (with singleton uncomplicated pregnancies) during labour and on days 1, 2 and 3 of the puerperium. There were no significant differences in FVIII, VWF:Ag and VWF:CB on days 1 and 2 of the puerperium compared with levels during labour. There was a significant decrease in VWF:Ag (P = 0.009) and VWF:CB (P = 0.04) on day 3. Age, ethnicity, duration of labour and mode of delivery did not have any significant effect on the changes in FVIII and VWF levels. The pregnancy induced increase in FVIII and VWF is maintained in the first 48 h after delivery. VWF levels start to decline on day 3 postdelivery.

There are currently limited data on the use of endometrial ablation in the treatment of heavy menstrual bleeding (HMB) in women with inherited bleeding disorders (IBDs). A retrospective review of prospectively collected data was performed. Twelve women with IBDs who had received endometrial ablation for the treatment of HMB were identified and their records reviewed. Details of their menstrual history; quality of life (QOL) and amount of menstrual blood loss [as assessed by pictorial blood-loss assessment chart (PBAC) and haemoglobin (Hb) concentration] pre and post-ablation were collected. Twelve women were included. The median duration of follow-up post-ablation was 32 months (range, 6-76). The median duration of menstruation decreased from 11 to 0 days after treatment (P = 0.004). Median PBAC scores decreased from 1208 preop to 0 post-ablation (P = 0.002).The median Hb concentrations (10.5-13.1 g dL(-1)) and QOL scores (median, 17-54) improved significantly after endometrial ablation (P < 0.01). Endometrial ablation appears to be a safe and effective long-term treatment for HMB in women with IDBs. It significantly decreases menstrual blood loss and improves QOL.

Pregnancy, labour and delivery present intrinsic haemostatic challenges to women with and carriers of bleeding disorders and their offspring. Deficiency of fibrinogen and factor XIII are associated with miscarriage, placental abruption and foetal loss. The risk of antenatal complications including antepartum haemorrhage is unknown in women with other bleeding disorders. There is a significant risk of postpartum haemorrhage (primary and secondary) in women with all types of bleeding disorders. This can be serious and life threatening in those with severe defects such as Bernard Soulier syndrome and Glanzmann's thrombasthenia. Three to four percent of infants with haemophilia experience cranial bleeding that occurs during labour and delivery. The safest method of delivery for affected babies remains controversial. However, the rate of planned Caesarean section is increasing among known carriers of haemophilia. If vaginal delivery is planned, prolonged labour and difficult delivery especially vacuum extraction are associated with the highest risk of cranial bleeding and should be avoided. The optimal management of pregnancy in women with inherited bleeding disorders requires a multidisciplinary approach and advanced individualized management plan taking into consideration obstetric and bleeding risk factors. Women with mild or moderate bleeding disorders can be managed at their local maternity unit in close collaboration with a tertiary centre. However, those with severe or rare disorders or carrying an affected infant should be managed in a tertiary centre with an onsite Haemophilia centre.
