Aortic Disruption (Traumatic)
Pathophysiology of Traumatic Aortic Disruption
Complete rupture causes rapid death by exsanguination. Partial disruption with contained rupture tends to occur near the ligamentum arteriosum (see figure Most partial ruptures of the aorta occur near the ligamentum arteriosum ) and to have blood flow maintained, usually by an intact adventitial layer. However, partial ruptures may also cause limited mediastinal hematomas.
