Figure 3: Various configurations of thoracic endovascular aneurysm repair depending on anatomy and clinical requirements. (a) Ideal configuration with a short stent-graft and left subclavian artery preserved. (b) Insufficient proximal “landing-zone,” the stent-graft covers the left subclavian artery. (c) The left subclavian artery requires preservation, specialist branch grafts now exist (d) Carotid-subclavian bypass to revascularize the left subclavian artery
