  Purpose
The main objective of this study is to obtain data to determine, in each individual with and without wearing compression stockings of different strengths and during different postures, the relationship between interface pressure and the area and circumference of the great saphenous vein and posterior tibial veins in the calf and ankle.

Condition
Venous Insufficiency

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Cross-Sectional
Official Title: The Effects of Compression Stockings on Pressure Parameters in Patients With Chronic Venous Insufficiency

Primary Outcome Measures:
  • Correlation between D and A/F at the calf [ Time Frame: Baseline (Day 0) ]
    D = the diameters of the largest cross section of the posterior tibial veins at calf level; A = the area of the largest cross section of the posterior tibial veins at the calf level; F = interface pressure measured along the leg using a 13 captor system.


Secondary Outcome Measures:
  • Interface pressure for the leg [ Time Frame: baseline; day 0 ]
    Interface pressure (mmHg) measured using 13 captors over the entire leg in the following positions: decubitus dorsal, sitting, orthostatic and orthodynamic.

  • Calf interstitial pressure [ Time Frame: base line; day 0 ]
    Intramuscular interstitial pressure is measured in the calf for 1/3 or randomly selected participants in the following positions: decubitus dorsal, sitting, orthostatic and orthodynamic.

  • Venous pressure at the ankle (mmHg) [ Time Frame: baseline; day 0 ]
    Pressure of the great saphenous vein is measured at the ankle in the following positions: decubitus dorsal, sitting, orthostatic and orthodynamic

  • Saphenous vein area, calf [ Time Frame: baseline, day 0 ]
    Area (mm^2)of the largest cross section of the great saphenous vein at calf level and for the following positions: decubitus dorsal, sitting, orthostatic

    Area (mm^2)of the largest cross section of the great saphenous vein at ankle level and for the following positions: decubitus dorsal, sitting, orthostatic

  • Posterior tibial vein area, calf [ Time Frame: baseline, day 0 ]
    Area (mm^2)of the largest cross section of the posterior tibial veins at calf level and for the following positions: decubitus dorsal, sitting, orthostatic

  • Posterior tibial vein area, ankle [ Time Frame: baseline, day 0 ]
    Area (mm^2)of the largest cross section of the posterior tibial veins at ankle level and for the following positions: decubitus dorsal, sitting, orthostatic

  • Saphenous vein perimeter, calf [ Time Frame: baseline, day 0 ]
    Perimeter (mm)of the largest cross section of the great saphenous vein at calf level and for the following positions: decubitus dorsal, sitting, orthostatic

  • Saphenous vein perimeter, ankle [ Time Frame: baseline, day 0 ]
    Perimeter (mm)of the largest cross section of the great saphenous vein at ankle level and for the following positions: decubitus dorsal, sitting, orthostatic

  • Posterior tibial vein perimeter, calf [ Time Frame: baseline, day 0 ]
    Perimeter (mm)of the largest cross section of the posterior tibial veins at calf level and for the following positions: decubitus dorsal, sitting, orthostatic

  • Posterior tibial vein perimeter, ankle [ Time Frame: baseline, day 0 ]
    Perimeter (mm)of the largest cross section of the posterior tibial veins at ankle level and for the following positions: decubitus dorsal, sitting, orthostatic

  • Heart height difference (mm); saphenous vein, calf [ Time Frame: baseline, day 0 ]
    The difference in height (mm) between the right atrium and the target cross section on the saphenous vein in the following positions: decubitus dorsal, sitting, orthostatic.

  • Heart height difference (mm); saphenous vein, ankle [ Time Frame: baseline, day 0 ]
    The difference in height (mm) between the right atrium and the target cross section on the saphenous vein in the following positions: decubitus dorsal, sitting, orthostatic.

  • Heart height difference (mm); posterior tibial veins, calf [ Time Frame: baseline, day 0 ]
    The difference in height (mm) between the right atrium and the target cross section on the posterior tibial veins in the following positions: decubitus dorsal, sitting, orthostatic.

  • Heart height difference (mm); posterior tibial vein, ankle [ Time Frame: baseline, day 0 ]
    The difference in height (mm) between the right atrium and the target cross section on the posterior tibial veins in the following positions: decubitus dorsal, sitting, orthostatic.

  • Leg circumference (mm) [ Time Frame: baseline; Day 0 ]
    The circumference of the leg is measured every 5 cm in a decubitus dorsal position.
