title: A case of acute traumatic aortic injury of a right-sided aortic arch with rupture of an aberrant left subclavian artery.
abstract: Acute traumatic aortic injury is a potentially lethal condition with most patients die at the scene of the accidents. Rapid deceleration due to motor vehicle accidents is the commonest mechanism of injury. These injuries can be successfully repaired in the few patients who survive the initial trauma if proper diagnosis and rapid treatment are provided. The occurrence of acute traumatic aortic injury in patients with congenital abnormality of the aortic arch has been rarely reported; however, it renders the diagnosis and treatment more difficult. In this paper, we describe an extremely rare case of aortic injury in a young patient who had a right sided aortic arch with rupture of an aberrant left subclavian artery. The patient was suspected to have a Kommerell's diverticulum in the aberrant subclavian artery origin. This injury resulted in an unusually huge pseudoaneurysm involving part of the mediastinum and extending into the neck. Unfortunately; patient succumbed in spite of surgical intervention.
