Fig 2 Distribution of diameters of the great saphenous vein at the saphenofemoral junction with subgroup populations based on closure level. A, The mean diameter of the saphenous vein for all patients who underwent RFA was 7.34 mm. B, The mean diameter of the saphenous vein in patients with level 1-3 closure who did not require anticoagulation was 7.29 mm. C, The mean diameter of the saphenous vein in patients with level 4 or 5 closure who did require anticoagulation was 10.46 mm.
