Fig 1 Proximal thoracic aortic landing zones. The figure depicts the proximal endovascular landing zones of the thoracic aorta. Zone 0 is defined as the ascending aorta, which covers all the arch vessels. Zone 1 includes coverage of the left carotid and subclavian arteries. Zone 2 covers the left subclavian artery. Zone 3 encroaches upon, but does not cover the left subclavian artery. Zone 4 is limited to the descending thoracic aorta beyond any of the origins of the arch vessels.
