Endovascular Treatment of Type B Aortic Dissection: The Challenge of Late Success

Patients with both acute and chronic type B aortic dissection had excellent initial results with thoracic endovascular aortic repair. Although event-free survival rates decreased gradually with time owing to the frequent need for new interventions, survival curves were comparable to those for less complex patients undergoing clinical or surgical treatment. Randomized studies are required to establish the actual benefit of this new approach.
