CEAP classification

The CEAP (Clinical, Etiological, Anatomical, Pathophysiology) classification is a standardized system used to describe chronic venous disorders. It consists of four main components:

 

Clinical classification (C)- 

C0: No visible or palpable signs of venous disease

C1: Telangectasia / Reticular vein 

C2: Varicose vein

C3: Edema 

 

C4- Skin changes due to venous disease

C4a: Eczema / Pigmentation 

C4b: Lipo dermato sclerosis (LDS) / Atrophie blanche

 

C5: Healed venous ulcer 

C6: Active venous ulcer 

 

Each clinical class is further characterised depending upon whether the patient is symptomatic (S) or asymptomatic (A).

 

Etiological classification (E)- 

Ec: Congenital

Ep: Primary

Es: Secondary (post-thrombotic)

En: No venous etiology identified

 

Anatomical classification (A)- 

As: Superficial veins

Ap: Perforator veins

Ad: Deep veins

An: No venous location identified

 

Pathophysiological classification (P)- 

Pr: Reflux

Po: Obstruction

Pr,o: Both reflux and obstruction

Pn: No identifiable venous pathophysiology
