Acute traumatic aortic injuries: posttherapy multidetector CT findings.
Acute traumatic aortic injury is a life-threatening entity that requires emergent treatment. Treatment was once performed with left thoracotomy, resection of the damaged aortic segment, and placement of an interposition graft. Within the past decade, endovascular therapy has gained increased acceptance, primarily because of a significant decrease in mortality and morbidity compared with those of surgery. The authors reviewed the experience with management of acute traumatic aortic injuries at their institution, as well as that reported in the literature. Complications after endovascular repair include endoleak, endograft collapse, stroke, upper extremity ischemia, paraplegia, graft infection, endograft structural failure, missed injury or stent migration, and access site complications. After surgical repair, paraplegia and ischemia to other organs, graft dehiscence, graft infection, and graft stenosis may occur. With the growing use of endovascular management of acute traumatic aortic injuries and the increased likelihood of patient survival, the radiologist will be expected to be familiar with the findings in these patients and is positioned to play a critical role in early recognition of potential complications. Early diagnosis of the complications of therapy for aortic injury is imperative for reduction of mortality and morbidity.
