Medical Therapy for Stanford B Type Aortic Dissection

Abstract

Medical management for Stanford B type aortic dissection includes lowering blood pressure and heart rate, and controlling pain to prevent further propagation of the dissection and lessen the risk for aortic rupture. Intravenous vasodilators including calcium channel blockade and beta blockade are initially administered. In the acute phase, oral and adhesive medications are administered as alternatives of intravenous medications to stabilize patients. In the chronic phase, hypotension and bradycardia should be noted. Beta blockade can be most appropriate to reduce aortic wall stress affected by the velocity of ventricular contraction (dP/dt).
