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• Laplace’s law• Compression stocking or bandage :
low pressures
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.
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
A new compression device
• Objectives
• To measure the interface pressures• point B1
• point F
• 1 CS
• 2 CS
• With a special pad and without pad
• Standing and supine position
A new compression device
• Objectives
• To evaluate the effects by CT scan with 3D
reconstruction on the GSV trunk of the
superimposition of 2 thigh CS before and after
adding the pad.
A new compression device
• Materials and method• Kikuhime device
• Mediven Struva thigh CS
( Point B 23 mm Hg in vitro)
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
• 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 B1 22+/- 1.8 cm
• Circumference at point F 50 +/-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 that the interposition of a specific foam pad produces a reduction of caliber of the GSV of over 50% under 2 CS.
