Study of Potential Mechanisms of Traumatic Rupture of the Aorta Using InSitu Experiments

An important transportation-related injury is traumatic rupture of the aorta (TRA). The authors discuss using in situ human cadaver experiments to investigate TRA mechanisms. One dynamic and four quasi-static tests were performed. Quasi-static experimentation involved cadaver mediastinal structure perturbation. Heart and aortic arch anterior, superior, and lateral displacement were investigated, and injuries ranging from complete transvection to partial tearing resulted, all in the peri-isthmic region. Primary injuries were associated with intimal tears. Average failure load and stretch for the quasi-static tests were 148 N and 30 percent. Study results show that TRA may occur without whole-body acceleration and intraluminal pressure, and ligamentum arteriosum likely has a limited role. Results also show that if pulmonary artery injury is absent TRA can occur and that the injury's principal aspect is descending thoracic aorta tethering by the parietal pleura.
