Abstract
In this study the compression pressure on the leg from four different ‘compression stockings’ was evaluated. A simple device for the measurement was constructed and is described. The effect of the stockings on venous function was also studied by foot-volumetry. Each of the four types of stockings was evaluated in 22 patients, all with mild to moderate insufficiency of the superficial venous system in the leg. Venous emptying from the foot and leg was significantly increased with all four stockings but with no difference between the types. The pressure measurements performed below knee and over the soft tissue area behind the tibia did not reveal the expected graduated compression. The pressure behind the medial malleolus, i.e. the venous ulcer area, was lower with all four stockings than higher up in the leg, indicating insufficient compression in this area.
