The annual incidence of aortic dissection (AoD) during pregnancy is about 0.4 cases per 100,000 persons (1). Although it is a rare entity, aortic dissection in pregnancy may result in adverse maternal and fetal outcomes. Half of the aortic dissections occur in the third trimester of pregnancy and in the postpartum period due to the hyperdynaemic state and the hormonal effect on the vasculature (2, 3). Atherosclerosis, hypertension, genetic disorders of connective tissue such as Marfan’s syndrome, genetic conditions such as Turner's syndrome, valvular abnormalities of the heart such as bicuspid aortic valve and vascular conditions like preeclampsia and cocaine abuse are some of the risk factors for AoD (4). The pregnancy alone with no underlying preexisting risk factors is a risk factor for AoD (5). The hyperdynamic changes in pregnancy and the increased oestrogen level which suppresses the synthesis of collagen and elastin may have weakened the vascular wall thereby playing an important role in the development of AoD during pregnancy (5).
