Thus, reducing it diameter during and after treatments is a fundamental therapeu- tic objective. Digressive compression don’t alter the diameter of the saphenous veins explaining some doubts about it efficiency. This is why we make eccentric compressions, often arti- sanal. The main of this study is the reduction of the diameter of the varicose vein under standardized eccentric compression, according to the territory of these varicose vein, their supra-facial situations or in the saphenous compartment situations, accord- ing to their depth, their nature: primitive or recurrence, in lying and standing positions. We measured 130 legs from 85 patients. A rectangular window was cut in the device for measuring the diameters and depths of varicose veins. The pressure sensor checked the interface pressure delivered by the com- pression device. The average patient age was 60 years old. Measurements confirmed the existence of a minimum pressure of 50 mm Hg. 77% were GSV, 23% were SSM, 95% primary varicose vein and 5% recurrences. 74% of varicose veins had a sub-fascial localiza- tion, 26% supra-fascial. In lying position the superficial varicose veins reduce their diameter by 43%, the saphenous veins by 36%. In standing posi- tion respectively 36% and 33%. This external tumescence allows a reduction in diameter of at least 43 %, thus, 70% reduction in their volume. This reduc- tion may be even better with an additional 75% stretch. It can be placed on the calf or on the thigh during the treatment but espe- cially after the treatments to reduce side effects (local pains, pigmentations, thrombectomies), complications and pro- motes harmonious fibrosis. It allows the reduction of the volumes and concentra- tions injected in the case of foam sclerosis. References 1. Jünger M, Konschake W, Haase H, Riebe H.
