Use of microcirculatory parameters to evaluate foam sclerotherapy treatment of superficial chronic venous disease, associated or not with venotonic drug: randomized, double-blind trial

FS treatment of the trunk veins reduced distal venous hypertension, improving microcirculation in all patients, helping to control the venous disease. All patients got therapeutic success (total occlusion or partial occlusion with improvement in venous reflux or reduction in venous caliber).
