Key result
Intraoperative preincision transesophageal echocardiography is important in the diagnosis and management of acute type A aortic dissection to avoid misdiagnosis from CTA pitfalls.
Why the study?
Does intraoperative preincision transesophageal echocardiography (TEE) improve the diagnostic accuracy of acute type A aortic dissection after contrast-enhanced CT angiography (CTA)?

Does intraoperative preincision transesophageal echocardiography (TEE) improve the diagnostic accuracy of acute type A aortic dissection after contrast-enhanced CT angiography (CTA)?
Intraoperative preincision TEE is crucial for confirming the diagnosis of acute type A aortic dissection and avoiding misdiagnosis from CTA artifacts.
Supports considering preincision TEE after equivocal CTA in acute type A dissection; leaves open routine adoption pending prospective data.
Contrast-enhanced CT angiography (CTA) currently is considered the diagnostic modality of choice in the diagnosis of acute type A aortic dissection. However, pitfalls associated with acquisition and interpretation of CTA images may result in misdiagnosis. We present examples of false-positive and false-negative interpretations of CTA in emergency situations that underline the importance of intraoperative preincision transesophageal echocardiography (TEE) in the diagnosis and management of this highly lethal entity.

Gologorsky et al. (2011) conducted a case report in Acute type A aortic dissection. Intraoperative preincision transesophageal echocardiography (TEE) was evaluated on False-positive and false-negative interpretations of CTA. Intraoperative preincision transesophageal echocardiography is important in the diagnosis and management of acute type A aortic dissection to avoid misdiagnosis from CTA pitfalls.
