Traumatic rupture of the aorta (TRA) is an important transportation-related injury. This study investigated TRA mechanism using in situ human cadaver experiments. Four quasi-static test and one dynamic test were performed. The quasi-state experiments were conducted by perturbing the mediastinal structures of the cadavers. The mechanism investigated included anterior, superior, and lateral displacement of the heart and aortic arch. The resulting injuries ranged from partial tears to complete transections. All injuries occurred within the peri-isthmic region. Initial tears were associated with the TRA can result from appropriate application of normal levels of longitudinal load and tension. The results demonstrate that intraluminal pressure and whole-body acceleration are not required for TRA to occur. The results suggest that the role of the ligament arteriosum is likely limited, and that TRA can occur in the absence of pulmonary artery injury. Tethering of the descending thoracic aorta by the parietal pleura is a principal aspect of this injury.
