The article is the result of the first stage of the study devoted to the analysis of the work of accreditation and simulation centers during the period of passing the primary specialized accreditation. The technical issues of the functioning of such centers, as well as the need to develop new methods of interaction between the accredited and the personnel of the simulation centers, were considered.

The article presents data from an original study to assess the quality and effectiveness of teaching "obstetrics and gynecology" using distance technologies during the pandemic of the new coronavirus infection COVID-19. The necessity of using simulation platforms for full and high-quality training in one of the main applied medical disciplines of the surgical profile is substantiated.

The need to form a new system of vocational education is dictated by the pace of modern life and the level of development of society. Increasing professionalism becomes possible with the use of new popular learning technologies. The modernization of the educational process affects all its components, including the methods and form of teaching, the style of communication between the teacher and students.

Introduction. Varicose veins disease of the lower extremities is often accompanied by edema, which persists even after the elimination of the causes of venous insufficiency. Clinically, the etiopathogenesis of edema in such patients is not always possible to differentiate. Objective. To determine the role of the lower limb lymphatic vasculature stucture variants in the development of chronic venous edema in patients with varicose veins disease. Materials and methods. A retrospective analysis of the results of X-ray contrast lymphography and radionuclide lymphoscintigraphy of 257 patients with different stages of chronic venous insufficiency (CVI). Results. Pathognomonic patterns of the lymphatic vasculature structure at various stages of lymphedema in patients with C3-C5 CVI were discovered. We found that the increasing number of cases of persistent oedema could be associated with the lower limb lymphatic vasculature hypoplasia and higher classes of CVI: 43.95 % among the patients with C4 CVI and 88 % with C5 CVI. The majority (94,1 %) of patients with C3 CVI with a normal-like lymphatic system presented with transitory oedema. With CVI C5, the capacity of the groin lymph nodes was impaired in 64 %. In C4 CVI, weak contrasting was observed in 45.1 %. With C3 – in 35.1 % of cases. Conclusions. The progressing degree of chronic venous oedema could be associated with the lymphatic vasculature hypoplasia and the malfunction of the groin lymph nodes.
