Directional continuous-wave Doppler sonography aids in evaluating vertebral artery (VA) and subclavian artery lesions. While not replacing angiography for vertebro-basilar insufficiency, it effectively identifies some critical vascular conditions.

Area of Science:

  • Vascular Surgery
  • Diagnostic Imaging
  • Neurology

Background:

  • Vertebro-basilar insufficiency is a significant clinical concern.
  • Accurate diagnosis of vertebral and subclavian artery lesions is crucial for patient management.
  • Conventional angiography is invasive, necessitating less invasive diagnostic alternatives.

Purpose of the Study:

  • To evaluate the diagnostic accuracy of directional continuous-wave Doppler sonography.
  • To compare Doppler sonography findings with brachial arteriography in patients with suspected vertebral and subclavian artery disease.
  • To determine the utility of Doppler sonography in identifying specific vascular lesions.

Main Methods:

  • Directional continuous-wave Doppler sonography was performed on 1,205 patients.

Related Experiment Videos

  • Sonographic findings were compared with unilateral or bilateral retrograde brachial arteriography results.
  • Analysis focused on the detection rates of various vertebral artery (VA) and basilar artery lesions.

    • Main Results:

    • Doppler sonography showed 33 false positives among 909 normal angiographic findings.
    • Complete subclavian steal syndrome was reliably detected (16/16 cases).
    • Sensitivity for severe VA stenosis was 16/31, and for VA occlusion with collaterals was 12/25. Some lesions, like distal basilar occlusions, were missed.

    Conclusions:

    • Conventional hand-held Doppler sonography cannot replace angiography for evaluating vertebro-basilar insufficiency.
    • Doppler sonography serves as an adjunct to angiography, aiding in decisions and follow-up.
    • Several therapeutically important vascular lesions can be readily diagnosed using sonography.
