Abstract
The hospital or medical examiner records of 75 victims of traumatic aortic rupture (TAR) were reviewed retrospectively. Among the 75 victims, 51 (68%) died at the scene. Those dead at the scene had higher Injury Severity Scores, 59.3 .+-. 13.8, than those who survived to be hospitalized, 42.6 .+-. 13.3 (p < 0.001). The mean age of victims dead at the scene was not different than the mean age of those who arrived alive at the hospital. The incidence of death at the scene was significantly higher for patients with head injuries (p < 0.01), victims with a second intrathoracic injury (p < 0.025), and patients with associated intra-abdominal injury (p < 0.001) compared to those without these injuries. A second fatal injury occurred in 51 (41.2%) of victims who died at the scene.
