Multicenter Study Clinical Trial Controlled Clinical Trial
Chronic venous insufficiency: worldwide results of the RELIEF study. Reflux assEssment and quaLity of lIfe improvEment with micronized Flavonoids.
Chronic venous insufficiency (CVI) results in considerable morbidity and may seriously affect patients' quality of life. The RELIEF (Reflux assEssment and quaLity of life improvEment with micronized Flavonoids) Study was a prospective controlled study designed to assess differences in the severity and in the evolution of symptoms and signs of CVI according to presence or not of venous reflux. Patients were thus separated into 2 comparative groups: those presenting venous reflux and those without venous reflux. ⋯ The relationship shown in this study between these parameters and clinical CEAP classification reflects the progressive nature of CVI. Despite obvious symptoms of CVI, a very low percentage (21.8%) of the "intention-to-treat" (ITT) population had previously been treated. This was the case whether venous reflux was present or not.
