Women with Turner's syndrome have a high incidence of cardiovascular complications, endocrine and hypertensive disorders. Those with the 45X chromosome complement require oocyte donation and in vitro fertilisation to conceive. Pregnancies in such women are challenging to manage due to the high risk of pregnancy-related hypertensive disorders, impaired glucose tolerance, fetal growth restriction and preterm birth. Women also need to be aware of the significant risk of aortic dilatation, dissection or rupture in pregnancy, which may be fatal. Despite these risks, favourable obstetric outcomes are achievable with careful pre-pregnancy counselling and cardiovascular assessment, intensive multidisciplinary antenatal monitoring and individualised delivery planning. We report the case of a 33-year-old woman with Turner's syndrome, pre-existing hypertension, insulin-dependent diabetes and primary hypoparathyroidism who had a successful pregnancy with good maternal and fetal outcomes despite the complexity of her medical conditions.
