Introduction. The Russian Phlebological Register began work in 2016 under the patronage of the Association of Phlebologists of Russia. The creation of a phlebological register in a separate municipal center of the country complements and enriches national plans. Aim. Тo investigate the trends in the organization of medical care to the population with chronic venous diseases (CVD) of a large industrial center using the phlebological register over the past 20 years. Materials and methods. The data of municipal and private medical institutions of Ekaterinburg from 2003 to 2022 are analyzed. Data on municipal hospitals (MHs) are provided by the TFOMS of the Sverdlovsk region. Data on private medical centers (PMCs) are obtained by exporting them from the electronic databases of each center. The statistics of phlebectomies (PhE), outpatient minimally invasive interventions and procedures are summarized. Results. Over the entire period of time, the number of classical phlebectomies in MHs decreased by 4 times – from 2300 (2003) to 587 (2022). At the same time, the development of minimally invasive procedures on the main veins in the PMCs increased from 313 (2003) to 4364 (2022). This made it possible to double the coverage of patients suffering from CVD with specialized medical care. In the structure of patients operated in MHs, the proportion of persons with severe chronic venous insufficiency (CVD C4–6) significantly decreased. The number of patients with superficial thrombophlebitis had a steady downward trend: the first 5 years (2003–2007) – about 200 PhE/year, then 5 years (2008–2012) – about 120 PhE/year, and from 2013 to 2022 < 100 PhE/year. Discussion. Private medical centers have consistently introduced the latest technologies, but endovasal laser coagulation remains the leader. Conclusion. The analysis of the register revealed a number of systemic changes in the organization of phlebological care.

To date, modern outpatient minimally invasive interventions for varicose veins, such as endovenous laser or radiofrequency ablation, microphlebectomy, sclerotherapy, non-thermal non-tumescent methods (NTNT), are widely introduced into clinical practice in the Russia. In the approved by the Ministry of Health of the Russian Federation in 2021 clinical guidelines "Varicose veins of the lower extremities" they are recommended as preferred over open surgery. At the same time, there are no federal regulations of preoperative examination of patients before these minimally invasive procedures for varicose veins. That is why the medical community is often forced to prescribe unnecessary diagnostic tests on the "just-in-case" principle, in order to protect itself for cases of complications and subsequent checks. This undoubtedly harms both the patients and the medical service, which has an additional useless and inappropriate burden. The purpose of the round table held on September 28, 2021 under the auspices of the Self-Regulatory Organization “The National College of Phlebology” together with the legal partner “The Faculty of Medical Law LLC” (Moscow), was to review the existing legislation on this issue and then to prepare a resolution regarding the justified preoperative examination of patients before minimally invasive interventions for varicose veins of the lower extremities. The prepared document consists of two parts. The first part presents the legal regulation of the diagnostic tests before interventions in phlebology. The second part contains the opinion of the professional community regarding the appropriateness or inexpediency of different pre-procedural examinations. In addition, based on the conclusions of legal analytics, a form of order of the chief physician has been developed, which regulates the diagnostic tests before the considered phlebological interventions in the clinic.

Introduction. Chronic venous disease significantly reduces quality of life and often leads to complications. The only way to eliminate hemodynamically significant blood flow disorders is the surgical method, incl. its latest modification is the VenaSeal.Objective of the study. To study the immediate and long-term results of the use of VenaSeal adhesive technology to obliterate the incompetent major saphenous veins, as well as the potential benefits in special groups of patients based on three-year experience in using VenaSeal Glue Procedure.Materials and methods. Over a 3-year period, we have treated 104 patients with VenaSeal. The average age was 59.6 ± 14.97 years, the CEAP class was 3.2 ± 1.09. 101 patients had varicose veins, in three cases - post-thrombotic. The intervention was performed on 117 incompetent main veins: GSV – 107, SSV – 10.Results and discussion. Clinical evaluation and ultrasound imaging of veins immediately after the intervention of vein occlusion throughout the intervention. There was no pronounced pain syndrome after surgery. Complications occurred in 3 patients in the form of chemical phlebitis. Long-term results up to 3 years were studied clinically and using ultrasound in 72 patients (76 veins): recanalization was noted in 2 GSV (2.6%), which in one case was accompanied by the formation of a recurrent varicose veins. To study the effect of VenaSeal on the quality of life in a comparative aspect, a non-randomized, single-center, open-label study was carried out; it included patients, incl. with GSV occlusion using RFA and EVLT. In the group of patients after VenaSeal, the quality of life indicators were better values. In addition, the absence of the need for elastic compression made the surgical treatment of patients with chronic venous disease and concomitant lesions of the peripheral arterial bed. In groups of elderly and senile patients, patients with weeping eczema, with obesity, additional advantages were found in the form of a decrease in the invasiveness of the intervention and the possibility of correcting reflux as a hemodynamic basis for the development of trophic disorders with the aim of their faster and more effective relief.Conclusions. Non-thermal obliteration of incompetent major saphenous veins using VenaSeal in varicose veins and post-thrombotic disease is highly effective: the immediate results assessed with clinical methods and using ultrasound duplex scanning confirmed the occlusion of the target vein in all cases. The study of long-term results revealed recanalization of two veins out of 76, which accounted for 2.6%.

Recently collated scientific data on the management of C1 clinical class of chronic venous disorders; wide prevalence of the disease and high variability amongst medical practitioners in relation to managing this category of patients and absence of any regulatory documents has prompted the development of clinical guidelines for the treatment of patients with reticular varicose veins and telangiectasias of the lower extremities and various parts of the body. These guidelines have been developed by a self-regulated organization Association “The National College of Phlebology”. The purpose of the de novo guidelines is to systematize the existing evidence and offer minimal standards of care for chronic venous disorders in C1 patients.

Objective: this paper aims at studying the efficacy of the thermocoagulation (TCG) method using TC-3000 apparatus for the treatment of lower extremity telangiectasias. Materials and methods. The TCG method has been used in 145 patients (223 cases) with telangiectasias (TA) and reticular veins (RV) of the lower extremities for 2 years. 17 patients (11.7%) had classes C1, 2 chronic venous diseases (CHV), and they underwent correction of pathological refluxes in the subcutaneous and perforating veins prior to TCG. Out of 128 patients with class C1 CHV, 25 people (19.5%) underwent microsclerotherapy (MST) in the past, just before the TCG procedure or in combination with it, MST was performed in 46 (35.9%). MST was performed for RV situated outside or within TA areas, and also was performed for TA from 0.6 to 1.0 mm in diameter. The TCG procedures were performed using TC-3000 (Belgium) apparatus, which operation is based on the impact of high-frequency electromagnetic field (4 MHz) on the dilated vessels in the skin. Needles made of nickel with a working diameter of 0.150 mm were used. Thermocoagulation was applied for the treatment of TA with a diameter of 0.3 mm to 0.6 mm. The results were evaluated within the following time-limits: 3 months (64 patients/97 limbs), 6 months (72/110), 12 months (70/107). Results of the treatment. The patients reported the results of the treatment as «no change and worse» in 73.4% of cases, pigmentation was detected in 73.2%, and residual TA in 81.4% of cases 3 months following the treatment. According to subjective assessment, the results were reported as «excellent» + «better» in 47.2%, pigmentation phenomena and residual TA were observed in 50.0% and in 50.9% of cases 6 months following the treatment. According to subjective assessment, the results were reported as «excellent» + «better» in 75.7%, pigmentation in 14.9%, residual TA in 13.1%, relapses TA in 14.0% 12 month following the treatment. Conclusion. 13.1% of patients with TA showed tolerance towards TCG. A positive effect included the absence of registered necrosis of the skin 3 months following the treatment, as well as atrophic and hypertrophic scars 12 months following the treatment.

Aim. To estimate a risk factor frequency of venous thromboembolism (VTE) in patients urgently hospitalized in hospitals, and also to estimate of patients part having effective prevention of VTE.Material and methods. ENDORSE (Epidemiologic International Day for the Evaluation of Patients at Risk of Venous Thrombosis in Acute Hospital Care Setting) is the international register. Patients of 40 years and older hospitalised in therapeutic departments as well as patients of 18 years and older hospitalised in surgical departments (358 hospitals in 32 countries) were included in the register. The case history analysis of all patients was performed for estimation of risk VTE and evaluation of preventive therapy quality according to American College of Chest Physicians (ACCP) Recommendation 2004.Results. Totally 68 183 patients (including 30 827 (45%) surgical patients and 37 356 (55%) therapeutic patients) were enrolled in Global ENDORSE Register. Russian centers enrolled 4 788 patients (including 2 829 (59%) surgical patients and 1 959 (41%) therapeutic patients). Totally 35 329 (51,8%) patients enrolled in Global ENDORSE Register (64,4% of surgical patients (19 842) and 41,5% of therapeutic patients (15 487)) had VTE risks. In Russia 2 188 enrolled patients (45,7%) had VTE risks (52% of surgical patients (1 470) and 36,7% of therapeutic patients (718). Totally 17 732 (50,2%) patients enrolled in Global Register ENDORSE and having VTE risks received VTE preventive therapy according to АССР Recommendations 2004. In Russia 521 (23,8%) patients enrolled in Global ENDORSE Register and having VTE risks received VTE preventive therapy according to АССР Recommendations 2004. It is more than 2 times less in comparison with world level (р
