Retrograde type A dissection is a near-never event during thoracic stent grafting for aortic dissection

Abstract

The management of type B aortic dissection has continued to evolve over the last two decades. This progression has largely been driven by two realizations. First, the understanding that “acute” dissection is a misnomer; the acute process of aortic dissection has long-term chronic implications. Late aneurysmal degeneration leads to aorta-specific mortality. Secondly, improvements in stent graft design and procedure-specific advancements have made thoracic endovascular aortic repair (TEVAR) more and more safe since the operation was first described.
