In suspected traumatic thoracic aorta injury, which bedside imaging is indicated for unstable patients?

• A. Bedside transesophageal echocardiography (TEE)
• B. CT angiography
• C. MRI
• D. Chest X-ray

Answer: (A)

When managing an unstable patient with suspected traumatic thoracic aorta injury, the priority is rapid bedside imaging that can visualize the aorta without delaying treatment. Bedside transesophageal echocardiography fits this need because it can be performed immediately at the patient’s bedside, does not require moving a unstable patient to a CT suite, and can directly visualize the thoracic aorta for signs of injury such as intimal tears, pseudoaneurysm, or rupture. It also helps assess concurrent problems like pericardial effusion or massive mediastinal hematoma that would influence urgent management. CT angiography, while excellent for detailed anatomy, requires transport to the CT scanner and hemodynamic stability, which isn’t guaranteed in an unstable patient. MRI is not practical in the acute setting due to time, monitoring needs, and availability. Chest X-ray is quick but insensitive for definitive diagnosis of traumatic thoracic aorta injury and cannot reliably exclude or confirm it.
