Abstract		Background CEAP classification of venous diseases included the clinical, etiological, anatomic, and pathophysiological mechanisms of chronic venous insufficiency. The aim of this study was to evaluate the convenience of Doppler ultrasound and photoplethysmography in the diagnostic work-up of chronic venous diseases, according to the CEAP clinical classification. Patients and methods 2 groups of subjects were incorporated in the study. The first group included 30 patients with mild chronic venous insufficiency, clinical stages C1, C2 and C3 of CEAP classification, while second group included 30 patients with severe chronic venous insufficiency (stages C4, C5 and C6). Venous hemodynamics evaluation was performed with Doppler ultrasound and photoplethysmography. Results A cross insufficiency was found by Doppler sonographic investigation in 10 (33%) of cases from the group of patients with mild venous insufficiency, whereas in the group with severe chronic venous insufficiency in 23 (76.7%) of cases (p < 0.001). In the group of patients with mild venous insufficiency, a pathological plethysmographic curve was observed in 11 (36.7%) out of a total of 30 subjects examined. At the same time, in the group of patients with severe chronic venous insufficiency, a shortening of plethysmografic curve was detected in 28 (93.3%) of subjects (p < 0.001). Conclusions In the group of patients with severe chronic venous insufficiency, clinical stages C4, C5 and C6, a significant higher number of pathological photoplethysmografic and ultrasound Doppler values were found, which indicates that the varicose veins are associated with a functional disturbances. CEAP clinical classification reflects functional disturbances in mild (stages C1, C2 and C3) and severe chronic venous insufficiency (stages C4, C5 and C6).
