 Aorta Research Reports AT ASRI

Aortic Isthums - Location of Most Ruptures Wayne State University Human Model Detailed Structure of the Aorta
 
  In 2003, Researchers at the William Lehman Injury Research Center published a paper citing concern over the frequency of Serious Injuries to the Aorta, that were observed among patients arriving at the University of Miami Trauma Center.  The Research Team investigated a population of vehicle crashes and found that aortic injuries were present in occupants exposed to relatively low severity near-side impacts. Further, these injuries were frequently undetected by first responders, but subsequently were fatal, due to a delayed rupture of the aorta.  It was evident to the Researchers that the existing safety regulations did not adequately prevent aortic injuries in some lower severity near-side crashes.  In addition, the number of injured who were dying due to undetected aortic damage was alarming.  To address these deficiencies, a research project was initiated that included the George Washington University, the University of Miami Medical School, and Wayne State University.  The research involved crash investigations, tests of human tissue, development of computer models, crash testing, computer reconstruction of crashes, and analysis of  human test data.  This research provides a basis for reducing highway casualties from aortic injury. The Research Project is summarized in the papers and presentations below.
