    Foot volumetry accurately assesses lower limb venous function, differentiating venous incompetence better than pressure measurements. It also identifies significant hemodynamic impairment in patients with deep vein thrombosis (DVT).

    Area of Science:

    • Vascular Medicine
    • Diagnostic Techniques
    • Medical Imaging

    Background:

    • The venous system of the lower limb is crucial for blood circulation.
    • Functional assessment of venous insufficiency is essential for patient management.
    • Established methods for venous assessment can be invasive or less precise.

    Purpose of the Study:

    • To evaluate foot volumetry as a non-invasive method for assessing lower limb venous function.
    • To compare the diagnostic accuracy of foot volumetry with venous pressure measurements.
    • To assess the utility of foot volumetry in patients with a history of deep vein thrombosis (DVT).

    Main Methods:

    • Foot volumetry was performed on patients with normal venous systems, superficial venous incompetence, and deep venous incompetence.

  • Results were compared with clinical examination, ascending phlebography, and venous pressure measurements.
  • Foot volumetry was also applied to a cohort of 113 patients with phlebographically proven DVT.

    • Main Results:

    • Foot volumetry demonstrated superior accuracy in differentiating between normal, superficial venous incompetence, and deep venous incompetence groups.
    • In patients with DVT, 77% of major DVT cases and 16% of calf vein thrombosis cases showed severe hemodynamic impairment.
    • These impairments were comparable to those observed in the post-phlebitic syndrome.

    Conclusions:

    • Foot volumetry is a precise, non-invasive tool for evaluating lower limb venous hemodynamics.
    • The technique effectively identifies significant venous dysfunction, including in post-DVT patients.
    • Findings underscore the clinical significance of foot volumetry in diagnosing and managing venous disorders.
