  1. 1. A new compression devicefor increasing interface pressures at the thigh level P ressure measurementsand assessment by a CT scanJean-Patrick Benigni * ** Jean-Franois Uhl **, Andr Cornu-Thenard **. * HIA Bgin, 69av. de Paris, F94163 St Mand ** French University Group for Medical Compression Study,Universit des Saints Pres, Paris V.
  2. 2. A new compression device
    • Background
      • Treatment of the great saphenous vein
        • Stripping and/or phlebectomy
        • UGS
        • Endovenous procedures
      • Thigh compression is little used
        • No consensus
        • Laplaces law
        • Compression stocking or bandage :
        • low pressures
  3. 3. A new compression device
    • Background
      • Nevertheless there are situations when thigh compression can be useful :
        • prevention of deep venous thrombosis,
        • relief of pain after surgery, endovenous procedures or sclerotherapy of the GSV,
        • prevention of recanalisation.
  4. 4. A new compression device
    • Background
      • Prevention of side effects
        • Direct and efficient compression on the thigh
        • Use of a pad between the compression and the skin
  5. 5. A new compression device
    • Objectives
      • To measure the interface pressures
        • point B1
        • point F
        • 1 CS
        • 2 CS
        • With a special pad and withoutpad
        • Standing and supine position
  6. 6. A new compression device
    • Objectives
        • To evaluate the effects by CT scan with 3D reconstruction on the GSV trunk of the superimposition of2 thigh CSbefore and after adding the pad.
  7. 7. A new compression device
    • Materials and method
        • Kikuhime device
        • Mediven Struva thigh CS
        • ( Point B 23 mm Hgin vitro )
  8. 8. A new compression device
    • Material and methods
      • Foam pad
        • Hard foam core
        • Peripheral softer foam
        • 29 mm thick and 70 mm wide
        • Mediven Post Op Pad
  9. 9.
    • Material and methods
        • 10 healthy subjects
        • 6 measurements
        • Standing and supine
        • 3 times
        • 360 measurements

    • Results
      • Description of the population
        • 6 females and 4 males
        • 41.7+/-17.4 years old
        • Height 166.5+/-7.3 cm
        • Weight 61.1+/-8.4 kg
        • Circumference at point B122+/- 1.8 cm
        • Circumference at point F50 +/-3.4 cm

    • Conclusion
      • The interposition of a specific pad between 2CS and the skin can be used to increase the interface pressures
      • A CT scan with 3D reconstruction confirms thatthe interposition of a specific foam pad produces a reduction of caliber of the GSV of over 50% under 2 CS.
