Association for Academic SurgeryEvolution in management of adolescent blunt aortic injuries-a single institution 22-y experience

BackgroundIn children, severe, life-threatening traumatic injuries of the thoracic aorta can be seen after motor vehicle collisions (MVCs) resulting in a sudden deceleration. Concurrent injuries in the thorax and abdomen can make treatment prioritization difficult and require early recognition and prompt intervention. With the increased utilization of minimally invasive endovascular approaches to traumatic aortic (TA) injuries, patients are often spared the increased surgical morbidity (spinal cord ischemia and renal insults) that can be seen with an open technique. The aim of this study was to evaluate a single American College of Surgeons level 1 pediatric trauma center's 22-y experience with TA injuries in children.MethodsAfter the Institutional Review Board approval, a 22-y (January 1990-April 2013) retrospective review of all pediatric trauma patients admitted with TA injuries was performed. Patient demographics including age, injury detail, treatment, and outcomes were recorded for analysis.Results17 children (<21-y old) were identified with ages ranging from 13-20 y old. The most common mechanism of injury was MVC with all 17 children sustaining TA injuries. The traumatic injuries included aortic transection (9), intimal flap (5), pseudoaneurysm (2), and contained thoracic rupture (1). All children were managed operatively with those before 2008 using an open technique. The endovascular approach was used in 7/17 (41%) cases with the median length of hospitalization 12 d versus 22.5 d using the open approach (P < 0.05). No child required conversion from an endovascular to an open technique for treatment of the aortic injury. There were no operative deaths, no procedure-related paraplegia and all children were discharged home from the hospital. Two children had mild mental deficits as a result of head trauma.ConclusionsTA injuries are an uncommon injury in children and can result from MVCs or other sudden deceleration mechanisms. Surgical intervention is required in most of the cases and can be performed safely and effectively with low morbidity using an endovascular approach, which is the evolving approach of choice for thoracic aortic injuries. Lengthy follow-up care is recommended in children treated with an endovascular device to monitor for endoleaks and device complications.
