«RESULTS: The estimation of clinical symptoms allowed division of the patients with CVD into the following classes: C2—varicose vein; C3—varicose vein and edema; C4—varicose vein, edema, and skin lesions. Initially, ultrasound examination (echo-Doppler assay) was performed to assess the changes in the blood flow in the veins during the compression maneuver [20]. The recorded spectral signal of the flow curve revealed a reverse flow, which was longer than one second, during the compression maneuver in each patient with CVD included in the study (Figure S1). This sign called “reflux” is associated with incompetent venous valves.»
