Loeys-Dietz syndrome is a recently described condition which causes cardiovascular, craniofacial, neurocognitive and skeletal abnormalities due to mutations in components of the transforming growth factor-β signalling pathway. Associated vascular abnormalities include vessel tortuosity and an increased incidence of vascular dissection. Pregnancy increases the risk of aortic dissection compared to non-pregnant individuals and an underlying condition such as Loeys-Dietz syndrome increases this further. While aortic dissection is well described in pregnancy in Loeys-Dietz syndrome, some women can have uncomplicated deliveries, particularly when the risks of the condition are actively managed. Such pregnancies should be considered high-risk, and women should be counselled and managed accordingly. Here we describe two pregnancies in one woman, both with successful outcomes, followed by a summary of the key management principles.
Keywords: Loeys–Dietz syndrome; aortic dissection.
