Significance of symptoms and signs in patients with traumatic aortic rupture.

ABSTRACT

The records of 50 patients with traumatic aortic rupture (Group I) and 50 patients with blunt chest trauma but negative aortograms (Group II) were reviewed retrospectively. Symptoms and signs referable to the chest and thoracic aorta were recorded and compared in Group I and Group II patients. Each patient's chart was evaluated for chest pain, respiratory distress, thoracic back pain, hypotension, hypertension, and decreased femoral pulses. None of the symptoms or signs attained statistical significance between Group I and Group II patients. The only significant difference between Group I and Group II patients was in the injury severity score (ISS). The mean ISS for aortic rupture patients was 42.1 +/- 11.6 (SD), but was only 19.9 +/- 11.4 (SD) (P less than .001) for patients without aortic rupture. We conclude that the diagnosis of aortic rupture in patients sustaining blunt chest trauma cannot be accurately predicted or excluded on the basis of the patients' presenting complaints or physical findings.
