Differences in Aortic Diameter Measurements with Intravascular Ultrasound and Computed Tomography After Blunt Traumatic Aortic Injury

The TEVAR has become the standard therapy for blunt aortic injury, despite a dearth of long-term outcome data. The preoperative CT frequently underestimates aortic diameter compared with intraoperative IVUS. The implications of placing thoracic endografts and whether excessive oversizing results in long-term aortic dilation need to be the focus of long-term studies in these relatively young patients.
