Progression of varicose veins and chronic venous insufficiency in the general population in the Edinburgh Vein Study.

Objective: The natural history in the general population of chronic venous disease in the legs is not well understood. This has limited our ability to predict which patients will deteriorate and to assign clinical priorities. The aims of this study were to describe the progression of trunk varicose veins and chronic venous insufficiency (CVI) in the general population, to identify important lifestyle and clinical prognostic factors, and to determine the relationship between venous reflux and progression.
