The aim of this paper is to demonstrate the location of the venous foot pump using an anatomical study. Four hundred cadaveric feet were injected with green neoprene latex followed by a dissection. A coloured segmentation of the venous system was achieved. The Lejars’ concept of the venous sole of the foot is incorrect: the true blood venous reservoir of the foot is located deeply in the plantar veins, between the plantar muscles. The medial and mostly lateral plantar veins converge into the plexus shaped calcaneal crossroad, where the blood is ejected upwards into the two posterior tibial veins. In addition, the several medial perforators of the foot directly connect the deep system (medial plantar veins) to the superficial venous system (medial marginal vein). This forms a true ‘medial functional unit’ which is unique in the limb given its directional flow is from deep to superficial. In conclusion, the plantar veins play an important role in the physiology of the venous return since a venous reservoir of 25 mL of blood is mobilized upwards with each step during walking. Therefore, the impairment of the foot pump by a static foot disorder should be considered as an important risk factor for chronic venous disease, and should be evaluated and corrected in any patient with venous insufficiency.

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.

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: Epidemiological study related to the detection of chronic venous disease (CVD) in a Belgian population and gathering of a maximum amount of epidemiological data on CVD. Method: Survey based on a questionnaire completed by a general practitioner during consultation. Results: In total 3813 files of patients with CVD were completed and analysed. Of these patients suffering from CVD, 70% were women with a mean body mass index of 26.2 and a clinical, aetiological, anatomical and pathological elements classification as follows: C0 = 14; 10%; C1 = 14; 19%; C2 = 14; 29%; C3 = 14; 19%; C4 = 14; 16%; C5 = 14; 4%; C6 = 14; 3%. Risk factors, clinical signs, complications and therapeutic approach are analysed and described. Conclusion: High level of statistically analysable data could be obtained within a reasonable period. The study confirms the socioeconomic importance of CVD. For example, an industrial disablement of an average duration of 23.6 days is found in 6% of patients.

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.

Objectives: To present a novel scoring system for lower-extremity venous pathology (the LOVE score) and our experiences using it in our clinical practice to identify venous pathology with duplex ultrasound (DUS) and magnetic resonance venography (MRV). Method: A total of 40 patients, 30 suspected of chronic venous disease and 10 with acute deep vein thrombosis (DVT) were examined from the inferior vena cava (IVC) to the popliteal vein using DUS and MRV. The image findings were reported using the LOVE score. Results The majority of deep veins (368 out of 378 segments) were completely visualized by both our imaging techniques and could be analysed using the LOVE score. Both imaging techniques reported comparable findings with regard to the visualization of thrombus, obstruction, collaterals, trabeculations, anatomic variations and central venous compression (e.g. May–Thurner). Conclusions: The LOVE score can be used to expand and standardize the documentation of imaging the deep venous system beyond thrombosis, to help identify (optimal) treatment options in patients with venous disease, in both the clinical and research setting. This first assessment shows that both DUS and MRV are capable of systematically identifying a multitude of changes in the venous system.

Symptoms of chronic venous insufficiency have been known since antiquity. The prevalence of chronic venous insufficiency in Western Europe and the USA has been reported within the range from from 1 to 40% in women and from 1 to 17% in men [1]. As reported by the European authors, the average prevalence of chronic venous insufficiency with class C2-C6 (according to the CEAP classification) among the European population reaches 30% [2]. Edema syndrome remains one of the leading manifestations of chronic venous disease. Compression therapy is one of the main ways to combat edema. The arsenal of devices for the treatment of edematous syndrome is steadily expanding with the development of medical science. Today, in addition to inelastic compression wrap and elastic compression garments, brand-new compression products, circaid adjustable inelastic compression wraps are available.

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

Venous Function

Chronic venous disease is a common problem with a significant impact upon both afflicted individuals and the healthcare system. Normal venous function requires patency of the axial veins with a series of venous valves, and muscle pumps. Dysfunction of any of the normal structures may lead to venous hypertension and development of chronic venous insufficiency. There is a spectrum of manifestations of chronic venous insufficiency including skin changes and venous leg ulcers. Venous duplex ultrasound may be used to confirm the diagnosis and provide anatomical detail. The treatment of chronic venous insufficiency will be based on the severity of disease and guided by anatomical and pathophysiological considerations. Compressive garments have been a mainstay in treatment. Interventional methods have replaced many traditional surgical techniques but are still typically reserved for unsatisfactory response to conservative measures.

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.
