Traumatic disruption of the thoracic aorta: a rational approach to imaging.
An imaging strategy is crucial in patients who have sustained a traumatic disruption of the thoracic aorta. Of those who reach hospital alive, 70-90 per cent will survive if diagnosed early and treated appropriately. The clinician has many imaging techniques to choose from, but they vary considerably in their degree of accuracy and performance time. Consequently their appropriateness is dependent on the type of injury suspected, the haemodynamic stability of the patient and the availability and experience of the radiologists. This article describes the types and presentation of traumatic thoracic aortic disruption so that the advantages and disadvantages of the various imaging modalities can be explained. It concludes by presenting an imaging strategy for use when this condition is suspected.
