  11. CONCLUSIONS • - In standing position MCS do not reduce significantly epi-fascial vein caliber. • MCS, even at a medium range pressure around 20 mmHg, decrease trans-mural pressure. • External pressure is modulated by the fat tissue behaviour. • Skin inflammation following foam sclerotherapy are more frequently seen for epi-fascial veins than saphenous veins. • So, we hypothesize that MCS, increasing peri-venous pressure, could create a protective environment against local side effects of foam sclerotherapy.
