Abstract  Traumatic injuries to the aorta are a significant source of morbidity and mortality in trauma patients, which highlights the importance of rapid diagnosis and treatment. Multi-detector row computed tomography has become the primary imaging modality for the imaging assessment of the polytrauma patient because it is fast, noninvasive, and the data sets can be used to create tailored multi-planar reformatted images that optimally display the location and morphology of aortic trauma and its relationship to adjacent structures. Although the classic location of blunt injury to the aorta occurs just distal to the left subclavian artery, aortic injuries may occur at any location along the aorta and in any patient population. Radiologists should be prepared to evaluate these types of injuries in nontraditional planes that are tailored to each examination and to present the data to clinicians using commercially available 3D software for purposes of surgical planning. Here, we review in pictorial form atypical aortic injuries with emphasis on multi-planar reformations. [ABSTRACT FROM AUTHOR]

Abstract?? Blunt ascending aortic injuries are rare in clinical practice. We have encountered two types of injuries to the ascending aorta with multidetector computed tomography: (1) a tear of the wall of the aortic root with a contained rupture and associated hemopericardium and (2) a tear at the level of the aortic valve cusp without associated hemopericardium. In reviewing our experience with aortic trauma at our institution under IRB waiver of consent, we encountered two cases of ascending aortic rupture that illustrate the two injury patterns. We present these two cases to alert radiologists to the multidetector computed tomographic findings of this life-threatening injury. [ABSTRACT FROM AUTHOR]
