Manual lymphatic drainage (MLD) and pressure-therapy are part of the therapeutical gears used in physiotherapy for reducing edema. The solution to the problem of the reduction fo lymphedema of the extremities rests with the evacuation of the liquid phase and the resorption of the stagnant proteins in the interstitial compartment not being collected by the lymphatic system. The injection of a 99 Technetium-labelled colloid substance provides a functional approach to the problem of lymphatic stasis.
