Currently thoracic endovascular repair (TEVAR) has a limited role in uncomplicated type B aortic dissection. Aggressive medical therapy is deemed appropriate for most of these patients allowing one-year survival rate of 80-90%. Outcomes are less than optimal in the long term, however, since aorta related complications (disease progression, rapid deterioration, acute rupture and elevated mortality) may occur in up to 50% of patients at five years. Subgroups of patients with uncomplicated type B dissection may benefit from early stent-graft placement, but identification of these remains difficult. Only future studies, especially randomized trials, will clarify the utility of early TEVAR in the setting of uncomplicated acute type B dissection.
