Abstract
We report 2 cases of distal arch aneurysm treated by thoracic endovascular aneurysm repair (TEVAR) with the "double-chimney technique." This technique permitted the implantation of a thoracic stent graft in the ascending aorta over the arch branches while preserving perfusion of innominate and left common carotid arteries without debranching bypasses. The procedure is a feasible and less invasive treatment for distal arch aneurysm with a short proximal neck (<2 cm to the origin of the innominate artery) in patients at high risk when undergoing sternotomy and in emergent cases.
