Fig. 2 Number of perforators detected per limb expressed as a percentage of limbs examined. Numbers of perforators detected per limb were not significantly different in the groups (χ2, p = 0.094). Ap Normal, Apparently normal contralateral limb; SVI, superficial venous insufficiency; LDS, lipodermatosclerosis; DVI, deep venous insufficiency.
