✦ Synopsis

This mechanism may result in more veins regaining competence, thereby improving venous function. Neither of our studies addressed the question of whether small-sized veins (1-2 mm in diameter) are restored to competence by external compression, a mechanism that we suggested may explain the plethysmographic findings of some authors who have shown improved venous function following application of compression hosiery. Finally, Mr Payne and colleagues also mention that the application of compression hosiery reduced the peak reflux velocity. This may be due simply to the fact that stockings raise the interstitial tissue pressure, resulting in a reduced pressure gradient in the veins along the limb, or alternatively that external compression does indeed restore competence in small-sized veins. Our own feelings are that, while compression hosiery may act by restoring competence in large veins, it is unlikely to explain the overall efficacy of compression therapy, and we have turned our attention to investigating the effect on the microcirculation of the skin. This part of the circulation seems to be much more directly influenced by local compression than d o the large veins.
