Blunt traumatic aortic injury: CT angiography images and short review of current literature

Blunt traumatic aortic injury in high-energy motor vehicle accidents is a rare but life-threatening condition. Proper treatment after prompt and accurate diagnosis is critical to reduce the death rate. The purpose of this article was to highlight the points to be considered in blunt traumatic aortic injury due to high-energy motor vehicle accident.

Blunt Traumatic Aortic Injury

Traumatic aortic injuries represent a leading cause of death following motor-vehicular accidents. These injuries curry a very high mortality rate even though a significant number of patients reaches the hospital alive. These injuries are identified in the contest of a polytrauma work up and are almost always associated with multiple other severe traumatic injuries which makes the management of these patients very challenging. The technology advancements seen in recent years with radiologic imaging and the progress of the therapeutic options brought up by the uprise of endovascular therapy, along with the sophistication of the techniques of trauma resuscitation and intensive care management, have improved significantly the overall prognosis of these patients. Although traumatic aortic injuries need to be generally considered a life-threatening condition, their degree of severity may differ significantly from case to case requiring immediate repair in some patients, whereas their repair can be delayed in cases when the severity of the aortic injury does not represent an immediate threat to the patient life. Therefore, the challenge of treatment of the polytrauma patients with an aortic injury is to identify the best strategy of therapy able to prioritize the treatment of the injuries based on their lethal potential. In this contest, the ability of properly defining the severity of the aortic injury is the key-factor to allow the appropriate definition of a treatment strategy able to identify treatment priorities. In our experience, radiologic assessment of the aortic injury in correlation with the evaluation of clinical parameters and a comprehensive polytrauma assessment allows to optimize the ability of the trauma team to establish the most appropriate strategy for the care of this complex patients’ group.

Atypical presentation of isolated traumatic ascending aortic dissection with cardiac tamponade

Blunt traumatic aortic injury is a rare but life-threatening condition, usually following high-energy trauma. We present the case of a 79-year-old man who was transferred to a hospital complaining of nausea after being struck on the chest. Computed tomography led to diagnosis of ascending aortic dissection with cardiac tamponade. Emergent ascending aortic replacement was performed successfully and he was discharged home on postoperative day 24 without any complications. The key to early diagnosis of blunt traumatic aortic injury is careful and detailed history-taking. If trauma patients complain of unexplained symptoms, the threshold for conducting computed tomography should be lowered to avoid misdiagnosis or therapeutic delay.
