Imaging in thoracic trauma: the trauma surgeon's perspective

Abstract

Thoracic trauma is a common cause of significant disability and mortality. Most thoracic injury in developed countries results from motor vehicle crashes (MVC). Imaging of patients with thoracic trauma must be accurate and timely to avoid preventable death. Trauma surgeons prioritize imaging options based on the patient's hemodynamic status, associated injuries, and age. The screening test for the detection of life-threatening thoracic injury is the supine anteroposterior (AP) chest radiograph. Rib fractures are a marker for serious associated injuries, including abdominal injuries. Rib fractures are especially ominous in children and the elderly. Thoracic aortic injury is associated with high-speed mechanisms of injury and can occur in the absence of radiographic signs. Chest computed tomography (CT) can be used as a screening and diagnostic tool for suspected aortic injury. Aortography is reserved for patients with high suspicion of aortic injury or for confirmation of CT scan diagnosis.
