Management of chronic type B aortic dissection

Abstract

The standard of care first-line therapy for uncomplicated acute type B aortic dissection is medical therapy. As a result, many of these dissections progress to become chronic type B aortic dissections (CTBAD). In the following manuscript, we will outline the natural history of these lesions and review what constitutes a CTBAD by anatomy and chronology. We will also describe the long-term medical management and surveillance of these lesions, what constitutes high-risk features, and when intervention should be considered. Endovascular, open and hybrid management strategies, potential complications, and subsequently required surveillance will also be discussed. With proper medical management, surveillance, and intervention, CTBAD can be managed effectively and downstream morbidity minimized.
