Abstract

PURPOSE: To determine the effectiveness of helical computed tomography (CT) as a screening device to detect traumatic aortic rupture. MATERIALS AND METHODS: Helical CT was used to examine 1,518 patients with nontrivial blunt trauma. Of these patients, 127 (8.37%) with abnormal CT scans of the mediastinum or aorta underwent thoracic aortography-89 patients solely for evaluation of mediastinal hematoma depicted at CT. Imaging abnormalities were correlated with surgical or clinical outcome. RESULTS: Twenty-one aortic injuries were identified that ranged from subtle intimal flaps to complete aortic disruption. Helical CT was more sensitive than aortography (100% versus 94.4%, respectively) but less specific (81.7% versus 96.3%, respectively) in detection of aortic injuries in patients who underwent both examinations. The association between CT findings and outcome was φ = 0.62 (χ2 = 49.1,1 df, P < .01) and between aortography and outcome was φ = 0.85 (χ2 = 92.2,1 df, P < .001). The P value of the difference between the φ coefficients was .10. CONCLUSION: Helical CT of the chest is effective for screening critically injured patients with possible blunt thoracic aortic injuries.
