Thoracic endovascular aortic repair (TEVAR) and endovascular abdominal aortic aneurysm repair (EVAR) have become widely accepted techniques for the treatment of aortic aneurysms and dissections. Central to the success of TEVAR and EVAR is accurate endograft sizing. Key aspects to be discussed in this article include the importance of preprocedural centerline imaging with computed tomography angiography to evaluate the proximal and distal seal zones. This article will review TEVAR and EVAR endograft sizing, providing the interventionalist with practical advice to optimize patient selection and to improve procedural success.
