Long-term outcomes after endovascular aortic treatment in patients with thoracic aortic diseases.

Background: Endovascular treatments for thoracic aortic diseases have been adopted rapidly, and long-term studies are relevant for durability evaluation.

Objective: To evaluate the long-term results of a prospective observational study of endovascular treatment in patients with thoracic aortic diseases who underwent percutaneous implantation of self-expandable endoprostheses.

Methods: Procedural success was defined as the absence of endoleak into the aneurysm or dissection-induced false lumen, no migration, and no conversion to open surgery.
