Evaluation of the AIVARIX in Detecting Signs C 1-2 Classes of CVD

This study is a multicenter observational study, which is carried out in frame of routine clinical practice in Russia. The program will include patients suggestive to chronic venous diseases (CVDs) including but not limited to those with C1 and C2 classes by CEAP classification, who will be seeking professional phlebologists' consultation. Study conduction is scheduled in Russia in 2022-2023. The planned number of patients is 414

The main goal of this study is to describe the AIVARIX app accuracy in detecting C1 and C2 classes by CEAP classification of chronic venous disease (CVD) in patients who are consulted by phlebologists on symptoms and signs suggestive to CVD. At single visit, investigating physicians (phlebologists) will be assessing and collecting parameters of interest which they should input in eCRF. Following data will be collected at the visit: a signed consent form from a patient, demographic characteristics (age, sex), eligibility of a patient to the inclusion/ non-inclusion criteria, 1 (one) image of skin area of interest, conclusion on presence or absence of CVD or any other pathologic condition(s) made as a result of objective/ instrumental examination. In case there will be any information related to safety of a Servier drug provided, investigating physician will also collect the information and fill in the PV form (Appendix 1).
