Treatment algorithms for patients with (sub)acute type B aortic dissections.

Aortic dissection is the most common acute aortic syndrome and constitutes a potentially catastrophic cardiovascular condition. Traditionally, complicated acute type B dissection has been considered an indication for surgical treatment, whereas patients with uncomplicated dissection have been treated medically. In recent years, there has been a clear paradigm shift towards endovascular treatment of complicated type B dissection. This is founded in numerous reviews and meta-analyses demonstrating a lower perioperative mortality and morbidity for TEVAR in comparison to open surgical repair. In uncomplicated patients, treatment options are still a matter of debate. Best medical therapy shows acceptable early results with respect to in-hospital mortality and morbidity but fails to address the issue of late aortic expansion and aortic-related adverse events in a significant number of patients. There is increasing evidence that early TEVAR promotes false lumen thrombosis, induces remodeling of the aortic wall and should be considered preventively in selected patients with suitable anatomy. This report gives an overview of current literature on treatment options and optimal time of intervention, and finally proposes a treatment algorithm for acute type B aortic dissection.
