Ductus diverticulum: A confusing normal variant in the setting of trauma

Abstract

Our submission describes a case report of a patient presenting to Vancouver General Hospital following a motor vehicle collision (MVC). At the time of presentation the patient had a CTA of his chest, which revealed an anomaly of his aorta. A considerable amount of debate followed. It was unclear if this was as a result of the trauma or part of the patients’ original anatomy. Both diagnoses have very different treatment algorithms. Our submission outlines the natural history of aortic injuries, and radiological evaluation of aortic injuries. We outline the effectiveness of various modalities to test for the presence of aortic injuries. The need to make a rapid diagnosis in this clinical scenario adds to the difficulty of the situation. It is important to recognize these life threatening injuries, and distinguish them from benign variants. This awareness will avoid unnecessary surgery and ensure those who do require an urgent surgery receive it. The consequences of an error in diagnosis can be significant.
