Current Management of Uncomplicated Type B Aortic Dissection

Aortic dissection is the most common thoracic aortic emergency and is associated with significant morbidity and mortality. Initial complications are dependent on reduction of sheer stress against the aortic wall to protect against rupture and minimize progression of the aortic wall injury. In patients with dissection starting at or distal to the left subclavian artery (Stanford type B), initial management includes strict blood pressure and heart rate control with monitoring for any complications such as malperfusion, rupture, or hemodynamic instability. Following the acute dissection event, survivors are faced with the lifelong need for blood pressure control and surveillance imaging to monitor for potential aortic deterioration leading to rupture or aneurysm formation. This review will discuss the latest recommendations for current management of uncomplicated type B aortic dissection including the evolving role of endovascular therapies.
