Objective— To review the obstetric and gynaecological problems in women with congenital coagulopathies.
Design— Retrospective review.
Setting— Regional Adult Haemophilia Unit, Glasgow Royal Infirmary.
Subjects— All women in contact with the Unit over a period of 30 years, comprising eight with von Willebrand's disease, 18 obligate carriers of haemophilia A and five obligate carriers of Christmas disease. Each woman was interviewed and details of their obstetric and gynaecological histories were obtained and their case records were reviewed.
Main outcome measures— Haemostatic changes associated with pregnancy and gynaecological problems.
Results— In 14 pregnancies in seven patients with von Willebrand's disease, there were four primary and four secondary post-partum haemorrhages and a large perineal haematoma complicating an episiotomy. These problems arose despite the endogenous rise in factor VIIIc seen with pregnancy. All women seen with von Willebrand's disease complained of menorrhagia and had been referred to gynaecologists. Treatment included danazol, tranexamic acid and the contraceptive pill. Diagnostic curettagc resulted in severe haemorrhage in one woman and two women with pelvic pain and dyspareunia were found to have spontaneous broad ligament haematomas, one requiring surgery. In 43 pregnancies in obligate carriers of haemophilia A and Christmas disease there were five post-partum haemorrhages and a large perineal haematoma.
Conclusion— In von Willebrand's disease it should be noted that adequate laboratory correction of factor VIIIc levels does not ensure clinical haemostasis; hence platelet function should also be measured. Patients with congenital coagulopathies pose particular problems for the obstetrician and gynaecologist and should be managed in close association with the local haemophilia centre.
