[Aortic dissection in pregnancy]

During pregnancy, the occurrence of aortic dissection is a rare event immediately threatening fetal and maternal prognosis. Its occurrence is more common in cases of connective tissue disease. But the absence risk factor shall not exclude or delay diagnosis. We must learn to think about it, because the prognosis is highly dependent on time management. The clinical presentation of this medical and surgical emergency varies, and pregnancy adds its own symptoms. We have to ask without hesitation that echocardiography or chest CT be performed since these diagnostic methods are both reliable and available.
