Traditionally ascending aortic lesions have been repaired in open fashion: stenotomy, cardiopulmonary bypass, with or without deep hypothermic circulatory arrest. However, a subsegment of patients are deemed too high risk for open intervention. In the advent of endovascular advancement, this subset of patients may be treated with the use of stents (physician made, off-label use), branched stents, through a variety of methods and approaches. Although there are currently no large randomized, prospective studies, success has been seen in smaller case series. This review article addresses the identification of anatomy amenable to endovascular repair for management of type A aortic dissection, pseudoaneurysm, and zone 0 lesions. Different approaches to repair, including transapical, transeptal, femoral, common carotid, and axillary graft insertion are also examined. For endovascular treatment of ascending aortic lesions to grow as a field, devices made specifically for the ascending aorta need to be designed and larger trials are necessary to evaluate the rates of complications, morbidity, and mortality, and graft patency.
