Aortic Disruption (Traumatic)
Introduction
The aorta can rupture completely or incompletely after blunt or penetrating chest trauma. Signs may include asymmetric pulses or blood pressure, decreased blood flow to the lower extremities, and precordial systolic murmur. Diagnosis is often suspected because of the mechanism of injury and/or chest x-ray findings and confirmed by CT, ultrasonography, or aortography. Treatment is open repair or, more commonly, stent placement. (See also Overview of Thoracic Trauma .)
