Chronic venous insufficiency (CVI) can result in varicose veins or, if severe, may develop skin changes and leg ulcerations. This chapter details the classification and presentation of varicose veins and venous leg ulcers (CEAP classification). It outlines the recommended investigations for CVI such as handheld Doppler scan and venous duplex ultrasound scans. The management of CVI is to improve the venous and lymphatic flow thereby improving the skin oxygen transport through reducing oedema. This can be performed by graduated compression bandages.

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.

Miraculous Healing

The occurrence of the Peregrine's ulcer is scientifically explainable but its miraculous healing in one night cannot be explained by the current scientific knowledge. The long history of fluid mechanics, anatomic and pathophysiologic discoveries led to the better knowledge of hemodynamics in pathophysiology. The last technologies provided strong means to the assessment of venous insufficiency, especially Duplex Ultrasound. Renewed hemodynamic concepts provide a better explanation of the pathophysiology of venous leg ulcers as well as reliable outcomes and less recurrences for varicose veins and ulcers.

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.

SummaryIt is a hypothesis that autoimmune factors directed against endothelial cells play a role in developing venous insufficiency. We investigated the association between anti-endothelial cell antibodies (AECA) and the development of venous insufficiency and varicose veins. Patients, methods: 44 patients were evaluated with clinical examination and duplex ultrasound for diagnosing chronic venous insufficiency and varicose veins and 120 healthy volunteers were assigned as the control group without evidence of chronic venous insufficiency and varicose veins. All sera samples were analysed by using slides, each containing biochips coated with frozen sections of HUVEC (human umblical vein endothelial cells) and capillary-rich tissue such as skeletal muscle (Euroimmun, FB 1960–1005–2, Germany). If a positive reaction is obtained, specific antibodies of class IgA, IgG, IgM attach to the antigens. In a second step, the bound antibodies are stained with fluorescein labeled antihuman antibodies and visualised by fluorescence microscopy. Results: AECA was positive in 24 out of 44 patients (54.54%) and in 30 out of 120 volunteers (25%). We detected that anti HUVEC antibody occurred significantly more frequent in patients with chronic venous insufficiency or varicose veins: p = 0.0007, OR: 3.60 (1.65 < 7.92). Discussion: The presence of antibodies directed against the endothelial structure causes inflammatory cells of the immune system to move towards the location by both forming antigen-antibody complex and activating the complement system. Tissue damage may occur due to inflammation. In our study we have found a statistically significant relationship between antiendothelial cell antibodies and chronic venous insufficiency. Conclusion: Early diagnosis or prediction of venous insufficiency and/or varicose veins before the occurrence of symptoms may prevent the damage or even help to establish a prophylactic treatment.

Objective: To review the prevalence of and risk factors for varicose veins, chronic venous insufficiency (CVI) and venous leg ulcers. Data sources: MEDLINE was searched for the terms prevalence and varicose veins, chronic venous insufficiency, or venous leg ulcers. Study selection: The extant world literature (1966–1999) with a minimum of an available English abstract was collected. Ninety-nine studies were reviewed. Data extraction: Data were extracted on prevalence of diseases of the veins in the lower limb, age and gender of the subject populations, and other risk factors for those diseases examined by the original researchers. Data synthesis: The two most prominent risk factors for venous disease are increasing age and female gender. Additional risk factors for venous disease with at least some documentation in the literature include dietary patterns, obesity, physical activity, standing occupations, constrictive clothing, connective tissue laxity, and hormonal differences, including pregnancy. Family history is also a prominent risk factor, suggesting a genetic component. Conclusions: Varicose veins are found more commonly in women, and with increased age. The increase with age is linear, suggesting a constant incidence and cumulative prevalence. CVI is also more common in women and increases with age, but data are limited. Venous leg ulcers are much less common than varicose veins or CVI and show less of a female preponderance, but increase exponentially with age, suggesting a true increasing incidence with age.

Background The Venablock© Venous Closure System (Invamed, Ankara, Turkey) is a novel cyanoacrylate-based non-thermal non-tumescent embolization device to block refluxing truncal veins for chronic venous insufficiency and varicose veins. The aim was to prospectively evaluate the safety and 6 months efficacy of Venablock© for the treatment of primary great saphenous vein (GSV) and small saphenous vein (SSV) incompetency in a multi-ethnic cohort from Singapore. Methods This was a single arm, single investigator prospective study of 29 patients (39 limbs, 39 truncal veins) recruited over a 5-month period (August 2019 to February 2020), who were treated with the Venablock© device at a tertiary vascular unit in Singapore. Patients with symptomatic varicose veins (C2–6) and had truncal reflux > 0.5 second on venous Duplex ultrasound were included. Follow-up occurred at 2 weeks, 3 and 6 months with dedicated quality of life questionnaires and a targeted Duplex ultrasound performed to check for continued venous occlusion. Result Mean age was 61.4 (±11.0) years and mean BMI was 26.2 (±5.7) kg/m2. 11/29 (37.9%) were males. Most common CEAP class treated was 2 (12/29, 41.3%). Mean diameter of treated GSV was 5.7 (±2.0) mm, 4.8 (±1.7) mm and 4.2 (±1.3) mm for the proximal, mid and distal above knee segments respectively. Mean time from access puncture to sheath removal was 23.4 (±10.0) mins. Vein occlusion at 2 weeks, 3 and 6 months was 39/39 (100%), 39/39 (100%) and 36/37 (97.2%) respectively. 5/29 (17.2%) developed puncture site infections, of which 3/29 (7.7%) required formal surgical drainage. 3/29 (7.7%) developed phlebitis. At 6 months, revised Venous Clinical Severity Score improved from 5.2 (±3.5) to 2.1 (±2.9; p < .001); EuroQol-5 Dimension score, from 7.4 (±2.1) to 5.7 (±1.4; p < .001); Aberdeen Varicose Vein Questionnaire score, from 18.1 (±15.5) to 7.9 (±8.9; p = .007); and Chronic Venous Insufficiency Questionnaire, from 18.6 (±16.2) to 4.5 (±6.3; p < .001). Conclusion Venablock© is a safe and efficacious option of treating truncal venous insufficiency in a multi-ethnic Asian cohort from Singapore in the short term. There is a significant improvement in QoL. Longer follow-up is required to assess the durability of this technique, in particular the higher puncture site infection rates observed compared to other glue-based therapies.

The purpose of the study was to conduct a comparative assessment of the course of the postoperative period after phlebectomy and thermal ablation in patients with varicose veins of the lower extremities in the system of the great saphenous vein (GSV) with class C2 of chronic venous insufficiency (CVI) — CEAP class C2. Materials and methods: 455 patients (455 limbs) with CEAP class C2. Group 1 (n = 154) received stripping + minimally invasive phlebectomy; Group 2 — endovenous laser ablation (EVLA) of GSV trunk + sclerotherapy of varicose veins; 3 group (n = 150) — radiofrequency ablation (RFA) of the GSV + sclerotherapy. All patients were united by a single tactical solution — the elimination of pathological vertical reflux in GSV. In each group, patients were with similar hemodynamic profile were selected (Group 1 = 63; Group 2 = 61; Group 3 = 61). The course of the postoperative period (from 2 days to 2 months) was compared for pain (visual analog scale — VAS), clinical symptoms of chronic venous insufficiency, degree of satisfaction (Darvall questionnaire), and duration of disability. Statistical processing was carried out using Excel programs for Windows XP, MedCalc® (version 11.4.2.0., Mariakerke, Belgium). Results: Postoperative pain is more pronounced (during day 1 for Group 1–4.0, Group 2–3.0, Group 3–2.0) and more prolonged (up to 4 days) after open surgeries (p < 0.05). The dynamics of the clinical symptoms of CVI (including varicose syndrome and use of compression therapy) could not be fully evaluated in connection with the ongoing sclerotherapy procedures for patients of Groups 2 and 3. Satisfaction of patients with aesthetic aspects was higher than expected in all groups. Reliable statistical differences proved decrease in days of disability (Group 1–14; Group 2–4; Group 3–3) and earlier return to physical activities and work in patients after thermal ablation in comparison with phlebectomy. Conclusion: The study shows that all three methods for eliminating vertical reflux in the GSV can be proposed for a large category of patients with CEAP of class C3 and C2. Medical and social rehabilitation of patients using endovascular thermal ablation technologies proceeds faster, which is beneficial both for the patients and for society.

This study was carried out in the out patient department of Dhaka Medical College Hospital. 100 patients presented with chronic venous insufficiency during the period of January 2005 to June 2005 were studied to find out the various modes of presentation, risk factors and relationship of symptoms with age, sex and Body Mass Index of the patients. It was found that, maximum patients presented with heaviness in the leg (87%), followed by aching leg pain (75%), leg swelling (70%), cramping leg pain (68%), tiredness (48%), burning pain (43%), engorged leg vein (39%), restless leg at night (21%), throbbing leg pain (18%), itching (13%), various skin changes without active ulceration (7%) and active leg ulceration only 3% of cases. Increasing age of the patients, obesity, increasing number of pregnancy, prolonged standing and sitting position at work were found to be positively correlated with CVI. Advanced age is associated with more advanced stage of CVI according to clinical CEAP classification. There is almost equal sex distribution among the stages of CVI except in advanced stage, in stage C4, C5 and C6 there is 10 patients out of them 9 are male and only 1 is female. Relationship of symptoms with BMI of the patients were also sort out and found that, in C3 group of CEAP classification out of 61 patients 46 are obese according to BMI, of which 32 are female and 14 are male and only 17 patients have BMI within normal range, but in other group there is no significant difference in incidence between two groups.   DOI = 10.3329/jom.v9i1.1421 J MEDICINE 2008; 9 : 20-26
