Fig 4 Computed tomography angiography (CTA), angiogram, and intravascular ultrasound (IVUS) images of a patient with traumatic aortic injury. CTA shows irregular contour of the lesser curvature of the descending thoracic aorta at the isthmus consistent with a traumatic aortic injury (TAI). Although the angiogram was read as equivocal, IVUS clearly shows a Grade 2 TAI.
