Compression Technique after Sclerotherapy for Leg Varicose Veins

Abstract

The success of sclerotherapy for the treatment of leg varicose veins is believed to depend on uninterrupted compression of the veins at the sites of injection. In clinical practice, the duration and the amount of pressure are very important. However, there have been no randomized studies regarding the duration of compression or compression pressure. Proper randomized controlled trials are neccessary, in consideration of size, length and site of the varicose veins, extent of reflux, and sclerosing agents and techniques. The extent of the variation in pressure during posture changes and exercise is determined to a considerable extent by the bandaging materials. Short-stretch bandages produce a higher working pressure and a larger pressure difference between muscle contraction and relaxation during exercise compared with elastic materials. However, interface pressure under elastic materials during posture changes and exercise is similar to that under short-stretch bandages when compression pads are used, and pads effectively augment the muscle pump. In clinical practice, compression materials should be selected in consideration of their merits and demerits.
