Varicose saphenous veins are graded as C0-C6, with 7 grades, in the same way as chronic venous disease, and are evaluated using the American Venous Forum Revised Venous Classification System for clinical manifestations. Grade C0: No visible or palpable signs of venous disease. Grade C1: Dilated capillaries or reticular veins. Capillary dilatation is the convergence of dilated intradermal microveins. Reticular veins are dilated light blue subcutaneous veins 1-3 mm in diameter. Grade C2: Dilated subcutaneous veins ≥3 mm in diameter. the presence of recurrent varicose veins after intervention that did not occur before treatment in grade C2 is classified as grade C2r. Grade C3: Edema. Chronic venous disease is associated with edema, with increased fluid in the skin and subcutaneous tissues, which may appear as indentations on compression. In addition to subcutaneous edema, lymphedema is more persistent once present. Grade C4: Skin changes. Skin and subcutaneous tissue changes secondary to chronic venous disease, containing two subclasses, C4a (hyperpigmentation or eczema) and C4b (lipoid scleroderma or leukodystrophy). Class C5: Skin changes and healing ulcers. Healed venous ulcers may also show skin atrophy with color changes. Grade C6: Skin changes and active ulcers. Active venous ulcers (C6) are total skin defects that most often occur at the ankle, but may extend proximally and even form circumferential ulcers in the distal to mid calf. If any of the above manifestations related to varicose saphenous veins occur, please seek medical attention to avoid delay in treatment.
