Carotid endarterectomy without angiography

W M Blackshear, R G Connar

    The Journal of Cardiovascular Surgery
    |November 1, 1982
    PubMed
    Summary
    This summary is machine-generated.

    Pulsed Doppler ultrasonic arteriography accurately quantifies carotid stenosis, offering a noninvasive alternative to traditional angiography for patients with contrast allergies or contraindications. This imaging technique aids in evaluating extracranial carotid occlusive disease.

    Area of Science:

    • Vascular Surgery
    • Diagnostic Imaging
    • Neurology

    Background:

    • Extracranial carotid occlusive disease requires accurate assessment of stenosis.
    • Radiographic contrast media used in angiography can cause allergic reactions.
    • Noninvasive imaging modalities are needed for patient groups unable to undergo standard angiography.

    Observation:

    • Three patients with unilateral and one with bilateral hemispheric symptoms underwent pulsed Doppler ultrasonic arteriography.
    • These patients had contraindications to standard radiographic contrast media.
    • The study focused on evaluating internal carotid artery stenoses.

    Findings:

    • Pulsed Doppler ultrasonic imaging with real-time spectrum analysis identified four high-grade (>50% diameter reduction) and one low-grade (<50% diameter reduction) internal carotid stenoses.

  • Noninvasive findings were confirmed intraoperatively at endarterectomy in all five affected arteries.
  • The technique accurately quantitated the degree of atherosclerotic stenosis at the carotid bifurcation.

    • Implications:

    • Pulsed Doppler ultrasonic arteriography is a reliable, noninvasive method for assessing carotid bifurcation stenosis.
    • This technique can serve as a substitute for conventional angiography in select patient populations.
    • It improves diagnostic capabilities for patients with contrast media allergies or other contraindications to angiography.
