CEAP classification

Is an internationally recognised classification of venous disorders, often used by doctors to describe the disease. Clinical findings are divided into 7 groups (C0 to C6): C0 means no visible signs of venous disease, C1 small varicose veins such as spider veins, C2 varicose veins, C3 varicose veins with oedema, C4 varicose veins with skin changes, C5 healed venous leg ulcers and C6 active venous leg ulcers. In addition, it gives information on the cause of the disease, the vein system affected and the nature of the pathological changes.
