Spiral computed tomography (CT) and three dimensional (3D) CT angiography have rapidly
emerged as essential imaging studies in the evaluation of patients undergoing endovascular
interventions for aortic aneurysms and dissections. Its major advantages are the ability
to provide excellent spatial resolution of the aorta and major branch vessels prior
to intervention, detection of subtle perigraft leaks following stentgraft treatment
of aortic aneurysms, and providing detailed assessment of intimal flap anatomy in
acute aortic dissections. The purpose of this article is to describe the technique
and application of spiral CT before and after endovascular repair of aortic aneurysms
and dissections based upon the 5-year clinical experience at Stanford University.
