SummaryIntroduction: Varicose veins affect up to 40 % of men and up to 51 % of women. The patho-physiology of primary varicosis (chronic venous insufficiency, CVI) is poorly understood. Here, the available data on possible endocrine mechanisms in healthy and varicose veins are reviewed.Methods: An extensive literature search was conducted in PubMed using the following key words: Chronic venous insufficiency, CVI, chronic venous disease, CVD, varicosis, saphenous vein, pathogenesis, hormone.Results: Several theories ranging from incompetence of the valves to functional, biological or morphologic changes in different layers of the vein wall have been proposed. However, an increasing body of evidence suggests that endocrine mechanisms might be involved in the pathogenesis of primary varicosis. In this respect a growing number of hormones (e.g. estrogen, progesterone, relaxin-2, and oxytocin) and their receptors have been linked to primary varicosis in experimental, pharmacological and histological studies.Conclusion: In summary, endocrine-based mechanisms seem to play a role in the pathogenesis of primary varicosis. This opens up the perspective for pharmacological treatments targeting the various described endocrine regulatory networks.

Clinical Disorder

Chronic venous insufficiency (CVI) is a common, but underdiagnozed clinical disorder associated with a variety of signs and symptoms. The presence of leg edema in association  with varicose veins, and venous leg ulcer in later disease stages defines the disease. The pathogenesis of chronic venous disease  is based on venous reflux, obstruction, or a combination thereof.  Prior postthrombotic syndrome   is one of risk factor for CVI which may explain observed  prevalence of thrombophilia in CVI. Color flow duplex ultrasound is the gold standard for nearly all diagnostic issues related to chronic venous disease. Compression stockings are the mainstay for conservative management. Earlier use of venous ablation therapy should be considered in symptomatic patients with superficial tortuous vein

General Adult Population

Chronic venous diseases are frequent pathologies in the general population. The most common chronic venous pathologies are varicose veins and chronic venous insufficiency including post-thrombotic syndrome. In the general adult population, varicose veins are present in up to 25% of people with an increasing prevalence with age. Risk factors include advanced age, genetic predisposition, female sex, and multiparity. The term chronic venous insufficiency summarizes the clinical signs of chronic venous disease with oedema, skin changes, or venous ulcers. More than 15% of the population is affected by chronic venous insufficiency. Risk factors include advanced age, obesity, and prolonged sitting.

Aim To review epidemiologic data on progression of venous pathology in varicose veins and from varicose veins towards chronic venous insufficiency. Methods We searched Medline and PubMed for epidemiologic studies concerning progression of venous pathology. Results The data suggest that reflux progression may develop from segmental to multisegmental superficial reflux. In younger age, reflux in tributaries and non-saphenous veins is more frequent. In older age, more saphenous reflux develops and more proximal sites seem to be affected. A high proportion of uncomplicated varicose vein (C2) develops skin changes and chronic venous insufficiency (C3–C6). Significant risk factors for the progression of varicose vein towards venous leg ulcers are skin changes, corona phlebectatica, higher body mass index and popliteal vein reflux. During a 13.4-year follow-up period, 57.8% (4.3%/year) of all chronic venous disease patients showed progression of the disease. Summary Studies on the progression of venous pathology show a high progression rate of chronic venous disease. More follow-up studies are still needed to get better information about the risk of varicose vein patients for progression to venous leg ulcers and to answer the question which patients may benefit from early varicose vein interventions.

This study aimed to review the pathophysiology of varicose veins and chronic venous insufficiency and the recent surgical treatment trend. Varicose veins are tortuous, twisted, or lengthened veins in the lower extremities. It is part of the spectrum of chronic venous disease. Primary pathogenesis is increased chronic venous hypertension caused by valvular insufficiency, venous outflow obstruction, and calf muscle pump failure. Some patients complain of no symptoms, except report cosmetic concerns. If the varicose vein progresses to chronic venous insufficiency, it may cause edema of the lower limb. The skin lesion can present as hyperpigmentation of the median part of the ankle, congestive dermatitis, and even a skin ulcer. The varicose vein can be diagnosed easily by visual inspection after identifying the skin lesions. For non-surgical treatment, elastic stocking, Unna boots, and pneumatic compression devices are recommended to reduce venous pressure. High ligation with stripping has been the standard treatment for varicose veins to achieve symptom relief and improve cosmetic effects. Endovenous laser ablation, radiofrequency ablation, mechanochemical ablation, and the VenaSeal closure system have been introduced as surgical treatment methods. Recently, endovenous thermal/non-thermal ablations are recommended for treatment because both are less invasive techniques. The appropriate therapy should be selected after considering the patients’ symptoms and signs, anatomical structure, and economic burden of the treatment.

Background and Objectives. Chronic venous insufficiency (CVI) is a common pathology of the circulatory system and is associated with a high morbidity for the patients and causes high costs for the healthcare systems. Arterial stiffness has been shown to be a predictor of cardiovascular events and mortality. The relationship between CVI and arterial stiffness using pulse wave velocity (PWV) and augmentation index (Aix) was evaluated in this study. Methods. Sixty-two patients with the stage of C3-C5 chronic venous disease (CVD) and 48 healthy subjects were enrolled in the study. To assess arterial stiffness, all cases were evaluated with I.E.M. Mobil-O-Graph brand ambulatory blood pressure monitor device. PWV and Aix were used to assess arterial stiffness in this study. Results. The mean age was 61.9±11.05 years and 54 % of the patient population was females. PWV and Aix were significantly higher in CVI patients than controls (8.92±1.65 vs. 8.03±1.43, p=0.001; 25.51±8.14 vs. 20.15±9.49, p=0.003, respectively) and also positive linear correlation was observed between CVI and all measured arterial stiffness parameters (r=0.675 for CVI and PWV, r=0.659 for CVI and Aix, respectively). A PWV value of > 9.2 has 88.9 % sensitivity and 71.4 % specificity to predict the presence of CVI. Conclusions. PWV and Aix are the most commonly used, easy, reproducible, reliable methods in the clinic to assess arterial stiffness. Logistic regression analysis showed that PWV and Aix were the independent predictors of CVI. PWV has the sensitivity of 88.9 % and specificity of 71.4 % to detect the presence of CVI.

Introduction. COVID-19 infection raises many questions regarding the health condition of patients after they have had COVID-19. The aim of this study is to examine the characteristic symptoms of chronic venous insufficiency in the postcovid period.Materials and methods. The materials that were used for work included the results of studying the medical aid appealability, characteristic symptoms, diagnosis and treatment of symptoms of chronic venous insufficiency in persons who have had the coronavirus infection. 47 patients presented with complaints about deterioration of their condition after they had had COVID-19 over March to September 2021 period. Methods: general clinical examiniation, ultrasound angioscanning of veins of the lower extremities, laboratory coagulation tests.Results and discussion. Before deterioration, calf circumference was measured 22–24 cm at a typical measurement site in most patients (89%), after covid infection it reached 26–27 cm. Varicose veins remained soft, without intravascular formations, edema was often bilateral, asymmetric, pain was described as constant (5–6 VAS scores), patients had prominent signs of lymphostasis. 35 out of 47 people received diosmin-based venotonic drug of Russian manufacture at a dose of 1000 mg/day (one tablet twice a day), the course of treatment lasted one to two months. After that period, the edema subsided in 85% of patients, the severity of pain syndrome significantly reduced (up to 2–3 VAS scores). With regard to chronic venous insufficiency in patients with chronic diseases of lower extremity veins (mostly varicose and post-thrombotic diseases), the significant progress of disease was observed in almost 94% of follow-up cases. Diosmin is the main drug that is prescribed to treat chronic venous insufficiency. The drug has an angioprotective and venotonic effect, reduces the vein wall elasticity, increases venous tone, and decreases venous stasis, reduces capillary permeability and fragility, and increases their resistance, improves microcirculation and lymphatic drainage.Сonclusions. In the postcovid period, clinical symptoms of some chronic diseases occur/worsen, including clinical manifestations of chronic venous insufficiency. The use of Russian diosmin-based drug for the management of edema and pain syndrome is very promising.

Objective: To highlight gaps in knowledge concerning the epidemiology of chronic venous insufficiency and to indicate what future studies are required. Methods: Existing classifications are compared. Limitations of epidemiological studies are defined. Data from published series and from the Edinburgh Vein Study are presented. Synthesis: The Basle 1978 classification of chronic venous insufficiency (CVI) is a purely clinical classification in which the earliest grade is corona phlebectatica. The Porter 1988 classification of CVI attempted to correlate clinical grades with sites of venous incompe-tence. However, a consistent relationship does not exist. The CEAP classification separates the clinical grades (which do not include corona phlebectasia) from the anatomical segments. The CEAP clinical classification covers a range of venous manifestations but is not consistent. There is a need for further consideration of classifications. Published selected series of patients show that the frequency of incompetence in both deep and superficial systems increases in proportion to the severity of the clinical manifestations of venous disease. To understand the significance of these data we need to know the patterns of venous incompetence in the general population. Data from 1566 subjects between the ages of 18 and 64 years in the Edinburgh Vein Study, a randomly selected cross-section of members of the Edinburgh population, showed that the prevalence of CVI was age-related and was present in 9.2% of men and 6.6% of women. Men had a significantly higher frequency of reflux in the deep system than women. In order to direct therapeutic interventions where they are most appropriate we need to know which patients with the early stages of varicose veins progress to CVI and which patients with early CVI progress to the serious skin complications. Conclusions: Key information concerning the natural history of venous disease and its evolution in relation to haemodynamic abnormalities awaits the findings of longitudinal-cohort epidemiological studies which include the duplex scanning of large populations.

Objectives Transforming growth factor-beta1 (TGF-β1) may participate in local chronic inflammatory processes in varicose veins and in venous wall structure modifications through regulation of matrix metalloproteinases (MMP) and their inhibitors (tissue inhibitor of metalloproteinase (TIMP)). The aim of this study was to analyze the effect of TGF-β1 in the vein wall, namely on the gene expression of selected MMP, TIMP and TGF-β1 receptors. Methods Healthy vein samples were harvested from eight subjects who underwent coronary bypass graft surgery with great saphenous vein. Each vein sample was divided into two segments, which were cultivated separately in vitro (one of the segments had TGF-β1 added) and then submitted to gene expression analysis. Results In the TGF-β1 supplemented group, there was a general increase in the mean gene expression. Specifically, expression of MMP9, MMP12, TIMP1 and TIMP2 were statistically significant. Conclusion The results of this study demonstrate that the gene expression of MMP9, MMP12, TIMP1 and TIMP2 was influenced by the addition of TGF-β1. These results may be translated to chronic venous insufficiency framework and suggest involvement of TGF-β1 in the vein wall pathology.

Objective: To describe a practical technique to reliably find and study crural veins by duplex ultrasound scanning. Design: Prospective scanning of patients referred for evaluation of possible chronic deep venous insufficiency. Setting: A non-invasive vascular diagnostic laboratory in Melbourne, Australia. Patients: A study of 1340 legs in 917 consecutive patients referred with primary or recurrent varicose veins, or for evaluation of possible deep venous disease causing aching or swelling in the legs. Interventions: Examination of the crural veins by duplex ultrasound scanning. Main outcome measure: Identification of all three sets of crural veins. Results: Rates for detecting the posterior tibial, anterior tibial and peroneal veins were 97%, 92% and 91% respectively and all three were observed in 91%. If the last 1227 legs studied by colour-Doppler duplex ultrasound are considered, the rates for detection were 98%, 96% and 96% respectively. Conclusion: Examination of the crural veins can be a part of routine duplex ultrasound scanning in patients referred with suspected venous disease.

Objective: To determine the prevalence of chronic venous insufficiency in the general population and its association with varicose veins. Data sources: MEDLINE search 1980–94 plus scanning of reference lists in articles obtained. Study selection: Studies on venous disease in subjects not attending health services. Data synthesis: A formal systematic review of metaanalysis was not carried out because of the heterogeneity of the few available studies. Skin changes were found to occur in over 3% of adults, more so in women than men. The prevalence was higher in subjects with varicose veins and depended on the definition of skin changes and the severity of varicose veins. Approximately 0.3% of adults had an open varicose ulcer, and around 1% had an open or healed ulcer. Prevalence was higher in women and increased with age. Conclusions: The prevalence of chronic venous insufficiency was found to be common in the general population, but more studies of distribution and aetiology are required.
