Acute type B aortic dissection (identified within 2 weeks of symptom onset), as described using the Stanford classification, involves the aorta distal to the left subclavian artery and accounts for 25%-40% of all aortic dissections. The traditional treatment paradigm of medical management for uncomplicated acute type B dissection and open surgical intervention for early or late complications of type B dissection is currently undergoing a period of evolution as a result of the influence of minimally invasive thoracic endovascular aortic repair options. Thoracic endovascular repair has replaced open surgical repair as the preferred treatment for complicated acute type B dissection, and may also prove beneficial for prophylactic repair of uncomplicated acute type B dissection for high-risk patients. This review discusses the management of acute type B aortic dissection and long-term treatment considerations.
