Objective: To determine the temporal relationship between changes in calf muscle deoxygenated haemoglobin (HHb) measured by near-infrared spectroscopy (NIRS) during light-intensity exercise and clinical stages of chronic venous insufficiency (CVI).
Design And Methods: Calf muscle HHb level was obtained in 168 limbs of 158 patients with various clinical stages of CVI. Clinical manifestations were categorised according to the CEAP classification (CEAP, clinical, etiological, anatomical and pathophysiological), and the patients were divided into two groups: early CVI (C(0-3),E(p)(,s),A(s)(,d,p),P(r)(,o)) and advanced CVI (C(4-6),E(p)(,s), A(s)(,d,p),P(r)(,o)).
