The CEAP classification for chronic venous insufficiency categorises disease based on Clinical, Etiological, Anatomical, and Pathophysiological findings. A patient with active venous ulceration due to post-thrombotic deep venous incompetence is classified as:

• A C5 Ep As Pr
• B C6 Es Ad Pr ✓
• C C4b Ep Ap Pr
• D C6 Ep Ap Po

Explanation

CEAP classification: C6 = active venous ulcer (C5 = healed ulcer); Es = secondary/post-thrombotic etiology (Ep = primary); Ad = deep venous system involvement (As = superficial, Ap = perforator); Pr = reflux (pathophysiology). Post-thrombotic syndrome with active ulceration therefore classifies as C6 Es Ad Pr. Primary varicose veins with superficial reflux would be C2 Ep As Pr. The distinction between Ep (primary) and Es (secondary/post-thrombotic) has therapeutic implications — secondary deep incompetence responds less well to simple superficial ablation.
