Medical therapy versus TEVAR for uncomplicated type B aortic dissection.

The standard of care in uncomplicated acute type B aortic dissection (uTBAD) has been optimal medical management. Surgical repair and endovascular interventions are adjuncts in managing complicated type B dissection. Increasing safety and confidence in the thoracic endovascular aortic repair (TEVAR) and recent data indicating long-term complications in medical management of uTBAD has brought a shift in treatment approach. TEVAR at best remains controversial, yet there is a subset, which will definitely benefit from intervention.
