    Directional continuous-wave Doppler sonography effectively detects basilar artery obstruction. This non-invasive method aids in diagnosing critical vertebrobasilar system conditions, improving patient outcomes.

    Area of Science:

    • Neurology
    • Vascular Imaging

    Background:

    • Vertebrobasilar artery obstruction poses significant neurological risks.
    • Accurate and timely diagnosis is crucial for patient management.

    Observation:

    • Directional continuous-wave (c-w) Doppler sonography was used to evaluate 6,380 patients over 3.5 years.
    • Specific criteria included bilateral sonographic silence or absent diastolic flow in vertebral arteries.

    Findings:

    • Seven cases of suspected basilar artery or distal vertebral artery obstruction were identified.
    • Angiography confirmed basilar artery occlusion in 4 patients, stenosis in 1, and bilateral vertebral artery occlusion in 1.
    • Three additional basilar artery occlusions were found via angiography, with one initially missed by Doppler.

    Implications:

    • Directional c-w Doppler sonography is a valuable tool for diagnosing basilar artery obstruction.
    • This technique can aid in identifying critical vascular events in the vertebrobasilar system.
    • Further investigation may refine Doppler criteria for enhanced diagnostic accuracy.
