[Doppler sonography in phlebological diagnosis]

F Bönniger-Beckers

    Fortschritte Der Medizin
    |April 9, 1981
    PubMed
    Summary

    Doppler sonography aids in diagnosing venous diseases by assessing blood flow signals. This technique reliably detects deep vein thrombosis but cannot diagnose calf vein thrombosis.

    Area of Science:

    • Vascular Medicine
    • Diagnostic Imaging

    Context:

    • Doppler sonography is an emerging technique in clinical phlebology.
    • It offers valuable insights into both arterial and venous circulatory systems.

    Purpose:

    • To evaluate the utility of Doppler sonography in diagnosing peripheral arterial diseases and venous conditions.
    • To assess its accuracy in detecting venous occlusion and valvular insufficiency.

    Summary:

    • Doppler sonography measures ankle systolic blood pressure to detect peripheral arterial disease severity.
    • It examines venous function by analyzing femoral vein blood flow patterns, distinguishing normal flow from pathological findings like continuous flow in venous occlusion.
    • The method is highly reliable for deep pelvic and femoral vein thrombosis but currently cannot diagnose calf vein thrombosis. It also identifies venous valvular insufficiency via continuous flow during Valsalva's maneuver, though it registers functional rather than morphological parameters.

    Impact:

    • Enhances the diagnostic capabilities for vascular conditions, particularly deep vein thrombosis.
    • Provides a non-invasive method for evaluating venous function and arterial pressure gradients.
    • Highlights limitations in diagnosing superficial venous thrombosis and the focus on functional rather than structural assessment.
