Abstract:

Thoracic endovascular aortic repair (TEVAR) has emerged as a less invasive alternative to conventional open surgery. Endografting techniques require a minimum 15-mm landing (sealing) zone proximally and distally and a minimum of 20 mm in a highly angulated arch to seal out the diseased aorta from the inside. 1 TEVAR for descending thoracic aortic aneurysms, in lesions with minimal anatomic restrictions, rapidly became the first-line treatment. At the same time, aneurysms of the aortic arch have been the “Achilles heel” of TEVAR2 due to the vital branches to the brain, curvature of the arch, and high blood flow in the area. 3 Thanks to substantial advances in endovascular techniques and graft materials, there now are several options for endovascular aortic arch repair.
