    Computed tomography (CT) effectively diagnosed dissecting aneurysms in all patients. While aortography provided better spatial detail, CT offered lower invasiveness and identified complications.

    Area of Science:

    • Medical imaging
    • Radiology
    • Vascular surgery

    Background:

    • Dissecting aneurysms are life-threatening vascular conditions.
    • Accurate diagnosis is crucial for timely intervention.
    • Computed tomography (CT) and angiography are key diagnostic modalities.

    Purpose of the Study:

    • To compare the diagnostic efficacy of CT and angiography for dissecting aneurysms.
    • To evaluate the strengths and limitations of each imaging technique.

    Main Methods:

    • Retrospective analysis of 32 patients with dissecting aneurysms.
    • All patients underwent computed tomography (CT) with contrast.
    • 21 patients also underwent angiography.

    Main Results:

    Related Experiment Videos

    • CT with contrast accurately diagnosed dissecting aneurysms in all 32 cases.
    • Angiography failed in 2 cases due to thrombosed dissections.
    • Angiography offered superior visualization of aortic branch involvement, particularly in the aortic arch.
    • CT demonstrated advantages in lower invasiveness, high sensitivity, and detection of concomitant complications.

    Conclusions:

    • CT is a highly sensitive and less invasive method for diagnosing dissecting aneurysms.
    • Angiography remains valuable for detailed assessment of aortic branch involvement.
    • The choice of imaging modality should consider diagnostic goals and patient factors.
