Implication

CT may serve as accurate non-invasive diagnostic tool for acute aortic dissection; leaves open need for larger prospective validation before practice change.

Key Points

To assess the diagnostic accuracy and clinical utility of computed tomography (CT) as the primary imaging modality for evaluating suspected acute aortic dissection.
Evaluated 26 consecutive patients with suspected acute aortic dissection using computed tomography as the primary investigation.
Confirmed CT findings with aortography (performed in 19 of 21 dissection cases), surgical exploration, or both.
CT achieved zero false-positive and zero false-negative results across all 26 evaluated patients.
CT correctly identified proximal (type A) dissection in two cases where aortography misclassified them as distal (type B) dissection.
Two patients were diagnosed solely via CT and underwent successful surgical confirmation without preliminary aortography.

Structured PICO

Does computed tomography (CT) accurately diagnose acute aortic dissection compared to aortography or surgery in patients with suspected acute aortic dissection?

Population

26 patients with suspected acute aortic dissection

Intervention

Computed tomography (CT) as the primary mode of investigation

Comparator

Aortography or surgery or both (reference standard)

Outcome

Diagnostic accuracy (false-positive and false-negative rates) for acute aortic dissectionsurrogate

Computed tomography is a highly accurate non-invasive imaging modality for the diagnosis of acute aortic dissection, performing at least as well as aortography.
