What is a varicose vein?
By definition, varicose veins are permanently dilated veins with problematic blood circulation. Their valves (membranous folds preventing the liquid from flowing back) sometimes become incompetent; a varicose vein forms when the venous accumulation generated by blood return combines with the sagging of the wall.
