Acute Type A Aortic Dissection in a 37-Week Pregnant Patient: An Unusual Clinical Presentation

Background

Aortic dissection in pregnancy is relatively rare, but it is often fatal. The estimated incidence of aortic dissection in the general population is 2.9 per 100,000 person-years. Early recognition and treatment of aortic dissections are crucial for survival. Whereas the majority of patients who present with aortic dissection are older than 50 years of age and have a history of hypertension, younger patients with connective tissue disease, bicuspid aortic valves, or a family history of aortic dissection are also at increased risk for developing this condition.

Case Report

We report the successful diagnosis and surgical repair of an acute type A aortic dissection in a 35-year-old woman who presented to the emergency department (ED) at 37 weeks of gestation.

Why Should an Emergency Physician Be Aware of This?

Emergency physicians should be alert to the possibility of aortic dissection in any pregnant woman who presents to the ED with unexplained chest, abdominal, or back pain, even those without risk factors for aortic dissection.
