Computed tomography of thoracic aortic trauma.
During a 63-month period, 28 consecutive patients suspicious for injury of the thoracic aorta were examined by computed tomography (CT). Twelve aortic ruptures were evidenced; pseudoaneurysm and mediastinal haematoma in close contact with the aorta were present in 12 patients, marginal lucency in 9, marginal irregularity in 8 and intimal flap in 6. CT was falsely negative in 1 patient with injury of the left subclavian artery. Angiography and surgery confirmed the diagnosis in 7 patients, and surgery alone in 5 patients. CT had a sensitivity of 92% and a specificity of 100%. The need for angiography was obviated in 67% of patients. A radiologist with experience in trauma management, CT and angiography should perform both examinations.
