Acute Complicated Type B Aortic Dissection: Do Alternative Strategies Versus Central Aortic Repair Make Sense?

Abstract

Current guidelines dictate emergency repair for an acute complicated type B aortic dissection (TBAD). Surgical approaches for the treatment of acute complicated TBAD can be divided into open and endovascular. The endovascular approach is further divided into central aortic repair and alternative endovascular techniques. Central repair includes endoluminal aortic stent graft repair, such as thoracic endovascular aortic aneurysm repair and provisional extension to induce complete attachment, extended provisional extension to induce complete attachment and stent-assisted balloon-induced intimal disruption and re-lamination in aortic dissection repair techniques. Alternative endovascular techniques include reno-visceral stenting, endovascular aortic membrane fenestration and targeted false lumen thrombosis. This review discusses and compares the various endovascular approaches to repair of acute complicated TBAD, focusing on central versus alternative endovascular techniques. We also discuss indications for technique selection, focusing on the acute management of complicated TBAD.
