What imaging technique should be used in unstable patients with suspected thoracic aorta rupture?

In the context of unstable patients suspected of having a thoracic aorta rupture, aortography is considered the preferred imaging technique. Aortography is an invasive procedure that involves injecting contrast dye directly into the aorta, allowing for immediate visualization of any ruptures or abnormal vascular conditions. This method provides critical information rapidly, which is essential in management decisions for unstable patients.

In cases of traumatic injury or suspected rupture of the thoracic aorta, time is of the essence. Aortography offers the advantage of being both diagnostic and potentially therapeutic, as it can be used to guide interventions if necessary. Its ability to provide a high-resolution view of the aorta in real-time makes it a crucial assessment tool in acute settings.

While other imaging methods like CT angiography are effective for diagnosing aortic injuries in stable patients and can provide excellent details about the aorta, they involve more time in terms of both acquisition and interpretation. In unstable patients, the goal is to achieve a rapid diagnosis and intervention; hence, aortography is often prioritized.

Additionally, while TEE provides good evaluation of the aorta and can be useful in some settings, it is not typically first-line for emergency evaluation of thoracic aorta ruptures, especially in unstable patients
