    Aortic dissection diagnosis can be challenging, with small tears in the ascending aorta potentially missed by imaging. This case highlights the risks of delayed surgical intervention for type A aortic dissection.

    Area of Science:

    • Cardiovascular Medicine
    • Diagnostic Imaging
    • Thoracic Surgery

    Background:

    • Aortic dissection, a serious cardiovascular emergency, requires accurate diagnosis for timely intervention.
    • Type A aortic dissection involves the ascending aorta and carries a high risk of mortality if not promptly treated surgically.

    Observation:

    • A case of type A aortic dissection was confirmed by postmortem examination.
    • Pre-mortem diagnostic imaging, including dynamic CT and aortography, failed to fully delineate the extent of the dissection.
    • Small intimal tears in the ascending aorta were identified as the likely cause of diagnostic difficulty.

    Findings:

    • Radiologic evaluations, despite being intensive, can miss subtle intimal tears in the ascending aorta.
    • The case underscores the limitations of dynamic CT and contrast aortography in fully characterizing complex aortic dissections.

  • Despite a diagnosis suggestive of type A aortic dissection, surgical intervention was withheld.

    • Implications:

    • Diagnostic challenges in aortic dissection necessitate a high index of suspicion, even with negative imaging.
    • Inappropriate non-surgical management of type A aortic dissection can lead to adverse outcomes.
    • Further research into advanced imaging techniques or improved diagnostic algorithms for aortic dissection may be warranted.
