Leg volumetry offers a simple, non-invasive method for assessing chronic venous insufficiency. This accurate and reproducible technique may be suitable for routine clinical practice.

Area of Science:

  • Vascular Medicine
  • Medical Devices
  • Diagnostic Techniques

Background:

  • Chronic venous insufficiency (CVI) quantification typically relies on invasive venous pressure measurements.
  • Existing non-invasive methods like air plethysmography are costly and time-consuming.
  • Leg volumetry presents a potentially practical alternative for routine CVI assessment.

Purpose of the Study:

  • To evaluate the practicability, accuracy, and reproducibility of leg volumetry for CVI quantification.
  • To establish leg volumetry as a viable non-invasive diagnostic tool.

Main Methods:

  • A water displacement method using a plexiglass boot was employed.
  • The study included 14 healthy volunteers (28 legs) and 11 patients with varicose veins (22 legs).

  • Measurements were taken by different observers and repeated on different mornings to assess accuracy and variability.

    • Main Results:

    • Leg volumetry demonstrated high accuracy (0.7%) and low intra-individual variability (1.3%).
    • Normal legs showed a mean volume of 2,449 ml with 6.2% variability, while patients' legs had a mean volume of 2,576 ml with 11.2% variability (p=0.05).
    • A statistically significant difference in leg volume was observed between morning and evening measurements in normal legs, indicating changes in venous function throughout the day.

    Conclusions:

    • Leg volumetry is a simple, inexpensive, and non-invasive method for quantifying chronic venous insufficiency.
    • The technique is accurate, reproducible, and potentially suitable for routine clinical use by non-medical personnel.
    • This method offers a practical alternative to traditional, more invasive CVI diagnostic procedures.
