Aortic dissection in pregnancy is identified by which features and what is the initial management?

• A. Sudden severe chest or back pain with pulse deficits; CT angiography to confirm; surgical emergency.
• B. Gradual chest pain relieved by rest; manage with beta blockers and observation.
• C. Dizziness and syncope; treat with hydration.
• D. Abdominal pain with fever; treat with antibiotics.

Answer: (A)

Aortic dissection in pregnancy tends to present with abrupt, severe chest or back pain, often accompanied by pulse deficits from malperfusion of branches. That combination—sudden, tearing pain with possible asymmetric pulses or blood pressures—should raise strong suspicion for dissection. Quick confirmation with imaging is essential, and CT angiography is the rapid, widely available modality that provides a clear map of the dissection. Because this condition can rapidly worsen and endanger both mother and fetus, it is treated as a surgical emergency when the ascending aorta is involved. The immediate management focuses on calming the aorta: start with pain control and goal-directed blood pressure and heart-rate reduction using a beta-blocker (such as labetalol or esmolol) to minimize shear stress, then add vasodilator therapy if needed to reach target pressures. After stabilization, definitive treatment follows the dissection type: type involving the ascending aorta requires urgent surgical repair, while distal, uncomplicated dissections may be managed medically or with endovascular approaches in select cases. The other options don’t fit because they describe gradual or non-typical symptoms and management that don’t address the life-threatening nature of dissection or the need for rapid confirmation and surgical intervention.
