Stanford type B aortic dissection is primarily managed with what?

• A. BP control
• B. Surgical repair
• C. Thrombolysis
• D. Antiplatelet therapy

Answer: (A)

In Stanford type B aortic dissection, the priority is to reduce the forces tearing the aorta apart by tightly controlling blood pressure and heart rate. This medical approach slows the propagation of the dissection and lowers the risk of rupture, making it the best initial management for uncomplicated cases. The usual goal is a systolic BP around 100–120 mmHg and a heart rate near 60 beats per minute. Achieve this with IV beta-blockers first (such as labetalol or esmolol) to blunt shear stress, and add a vasodilator (like nicardipine or clevidipine) if BP remains high after the heart rate is controlled. Analgesia helps reduce sympathetic drive and further limits stress on the aorta. Surgical repair is reserved for complications, such as ongoing malperfusion, rupture, or failure to control the dissection with medical therapy. Thrombolysis or antiplatelet therapy are not appropriate in the acute dissection context because they don’t address the tearing process and can worsen bleeding or extension of the tear.
