Brief Summary

The VAP-PRO-C3 is a multicenter observational program, which is carried out in the frame of routine consultations and follow-up of patients. The program includes patients with chronic venous diseases (CVDs) of CEAP class C3. It is scheduled in Russia for 2018-2019. The program is expected to enroll 90 phlebologists from 60 cities of Russia. The planned number of patients is 900

Outcome Measures

Primary Outcomes (2)

  • Dynamics of the Main Veno-specific Symptoms, Assessed by Visual Analog Scale (VAS) - Visit 0 vs Visit4

    Visual Analog Scale (VAS) was used in the VAP-PRO-C3 study in to discribe 5 criterions: 1.leg heaviness, 2.pain, 3. sensation of swelling, 4. night cramps 5. itching reduced from Description of the technique: It is a continuous scale in the form of a horizontal line 100 mm long with two extreme points located on it: "no symptom" and "the strongest symptom you can imagine." The patient is asked to place a line perpendicularly crossing the visual analogue scale at the point that corresponds to his symptom intensity. The ruler measures the distance (mm) between "no symptom" and "the strongest symptom you can imagine," providing a score range from 0 to 100. A higher score indicates a greater intensity of symptom.

  • Changes in the Severity of Edema, as Assessed by the Method of Truncated Cones.

    To assess changes in edema, the method of truncated cones and duplex ultrasound scanning (DUS) will be used. The method is based on the assumption that the shape of the lower extremity approaches the shape of several truncated cones connected by bases that coincide in area. The volume of the cone is calculated by measuring the circumference of the upper (C) and lower (c) cones and the height (h) between them. For calculating the volume of each cone, the following formula is used: V = (p / 12p) ² h (C² + Cc + c²), The volume of the lower limb is determined by summing the volumes of all the cones. The smaller the height of the segments, the more accurate the result.
