(A) Illustration of the stent graft sizing process. The length of the stent graft is determined from the subclavian artery bifurcation to 4 cm past the end of the aneurysm. The diameter of the stent graft is chosen based on 110% of the aortic diameter at the landing zone. (B) Measurement of the stent distal end level at the vertebral body (indicated by the black arrow). The landing zone angle (marked with an asterisk) is the angle between the distal end of the stent and the vertical axis.
