BACKGROUND: Blunt thoracic aortic injury (BTAI) is rare and associated with significant morbidity and mortality in trauma patients. As the population ages and life expectancy increases, the frequency of this injury will increase in the elderly and thus it behoves us to understand treatment and outcome in this patient population.
METHODS: We analysed prospectively collected data of 10 patients > 80 years old with BTAI (Group A) treated among 26,000 trauma patients over a 20-year period in a Level 1 trauma center to investigate BTAI morbidity and mortality. Age, gender, and injurity severity score (ISS) matching was performed to create a case-control study of elderly trauma patients with (Group A) and without BTAI (Group B).
RESULTS: Ten elderly trauma patients were found to have BTAI. Five (50%) were males and 5 (50%) were female. The cohort mean age was 86 years (range: 80 to 95). All but one patient (fall injury) were involved in motor vehicle accidents. The mean ISS in group A was 29 ± 12. In group A, 2 (20%) patients (ISS = 36 and 33) succumbed in the emergency department. Six (60%) patients were treated non-operatively and the remaining 2 (20%) patients (88 and 84 years) underwent open aortic repair with patch angioplasty and Dacron interposition grafting. No postoperative paraplegia or stroke related to surgery occurred. Two patients in Group A survived hospitalization and were eventually discharged. Patients in Group B had lower overall LOS, ICU LOS and 30-day mortality rates despite similar ISS.
CONCLUSION: Patients aged 80 or older who have experienced BTAI tend to have worse outcomes than those without BTAI regardless of similar ISS. Therefore, because of the low incident of this injury in general and particularly in the elderly, only pooled data from multiple institutions will be able to shed light on the complex issues surrounding treatment decisions in a group of patients with an a priori limited life expectancy.
