Risk factors for venous ulceration in patients with varicose veins of lower extremities

The aim of this case-control study was to explore the potential risk factors for venous ulceration in patients with varicose veins of lower extremities and to establish a simplified diagnostic score model. Seventy subjects with varicose veins of lower extremities and venous ulceration were compared with 1164 controls with varicose veins of lower extremities and no history of venous ulceration. Stepwise multivariate logistic regression analysis was used to identify the risk factors for venous ulceration. The steps in developing the diagnostic score model were based on the Framingham Heart study. The area under the receiver operating characteristic curve (AUC) was calculated to assess the diagnostic ability of the diagnostic score model. Multivariate analysis showed that men, overweight, obesity, longer duration varicose veins, deep venous valve insufficiency, low lymphocyte counts, and high fibrinogen content were independently associated with an increased risk of venous ulceration. The AUC for the diagnostic score model was 0.75, which indicated good discriminatory ability. Special attention should be paid to the high-risk group of patients with lower extremity varicose veins. The diagnostic score model might be a useful screening tool for clinicians, policy makers, and patients.

The relationship between demographic factors and syncopal symptom in pediatric vasovagal syncope

This research proposed to retrospectively analyze 20 years of clinical data and investigate the relationship between demographic factors and syncopal symptom in pediatric vasovagal syncope. A total of 2513 children, 1124 males and 1389 females, age range 3-18 years, who presented to Department of Pediatric Cardiovasology, Children's Medical Center, The Second Xiangya Hospital, Central South University with unexplained syncope or pre-syncope and were diagnosed with vasovagal syncope were retrospectively collected and divided into syncope group (n = 1262) and pre-syncope group (n = 1251). (1) Females had a 36% increased risk of syncope compared to males, a 27% increased risk of syncope for every 1-year increase in age, and a 2% decreased risk of syncope for every 1 cm increase in height. (2) A non-linear relationship between age, height, weight and syncope was observed. When age > 10.67 years, the risk of syncope increases by 45% for each 1-year increase in age; when height < 146 cm, the risk of syncope decreases by 4% for each 1 cm increase in height; when weight < 28.5 kg, the risk of syncope decreases by 10% for each 1 kg increase in weight. Demographic factors are strongly associated with syncopal symptom in pediatric vasovagal syncope and can help to predict the risk.

Investigation of the effect of visceral adiposity index on venous clinical severity score in patients with chronic venous insufficiency

INTRODUCTION

Chronic venous insufficiency (CVI) is a common disease affecting millions worldwide. Age, obesity, female gender, sedentary life, and long-standing at work causing orthostasis have been identified as predisposing factors.

OBJECTIVE

The visceral adiposity index (VAI) is an important indicator of abdominal obesity. Various studies in the cardiovascular field have shown that it may be more predictive than body mass index (BMI).

METHODS

A total of 171 consecutive patients diagnosed with low-grade (C0-C3) superficial primary CVI in our clinic, between November 2021 and December 2022, were included in this prospective study. Venous Clinical Severity Score (VCSS) values were calculated. The patients were divided into two groups according to their VCSS values (Group 1: VCSS ≤6 and Group 2: VCSS >6).

RESULTS

There were 110 patients in Group 1 with a median age of 42 (18-50) years. There was no difference between the groups in terms of gender, smoking, hypertension frequency, height, weight, body mass index, hemoglobin values, lymphocyte, neutrophil, mean platelet volume, urea, creatinine, high-density lipoprotein, low-density lipoprotein, triglyceride, and total cholesterol values (p > .05). Multivariate logistic regression analysis was performed to reveal the predictive factors of high VCSS values in patients. As a result of the analysis, VAI (Odds Ratio (OR): 1.775; 95% Confidence Interval (CI): 1.389-2.269; p < .001) and CRP (OR: 2.641; 95% CI: 1.431-4.875; p = .002) values were identified as independent predictors in predicting high VCSS values.

CONCLUSION

This current study showed that high VAI values affect clinical complaints in patients with low-grade CVI. In line with our results, clinical recommendations can be made to reduce VAI values in low-stage CVI patients.

Venous ulcers: look at the patient, not at the ulcer! Risk factors and comorbid conditions in venous ulcers of lower limbs

BACKGROUND

In venous leg ulcers (VLU), risk factors and comorbidities may affect prognosis and recurrence. Aim of this paper was to assess risk factors and most frequent medical conditions in venous ulcers.

METHODS

This a single center retrospective study from January 2017 to December 2020 on 172 patients with VLU admitted at our Center for Ulcer therapy in San Filippo Neri Hospital in Rome; data about medical history, Duplex scanning results and lifestyle questionnaire were collected in an Excel database and evaluated with Fisher test. Patients with lower limbs arterial insufficiency were excluded.

RESULTS

Incidence of VLU in patients over 65 was twice that in patients under 65 and woman were affected by VLU more than men (59.3% vs. 40.7%; P<0.001); more significant comorbidities were arterial hypertension in 44.19% (P=0.06), heart disease in 35.47% (P<0.001), chronic obstructive pulmonary disease (COPD) in 16.28% (P=0.008). In 33 patients (19% of cases) a trauma caused the ulcer. Diabetes, obesity, chronic renal insufficiency and orthopedic disease do not seem to have a direct influence on VLU.

CONCLUSIONS

Age, female sex, arterial hypertension, heart disease and COPD were significant risk factors. Thinking "globally" to the patient rather than only taking the ulcer into account is the key for a long-lasting therapeutic result; comorbidities are interconnected so weight loss, an exercise program for calf pump and compression must all be part of the VLU therapy, not only to heal the existing ulcer but also to prevent recurrences.

Race, sex, and socioeconomic disparities affect the clinical stage of patients presenting for treatment of superficial venous disease

OBJECTIVE

Superficial venous disease has a U.S. prevalence of nearly 30%, with advanced disease contributing to a significant healthcare burden. Although the risk factors for venous disease are well known, the correlation between race, sex, socioeconomic status, and disease severity on presentation is not well established. The area deprivation index (ADI) is a validated metric with respect to regional geography, social determinants of health, and degree of socioeconomic disadvantage. In the present study, we aimed to identify the disparities and the effect that the ADI, in addition to race and sex, has among patients associated with an advanced venous disease presentation.

METHODS

A retrospective review between 2012 and 2022 was performed at four tertiary U.S. institutions to identify patients who underwent endovenous closure of their saphenous veins. Patient demographics, state ADI, comorbidities, CEAP (clinical, etiologic, anatomic, pathophysiologic) classification, and periprocedural outcomes were included. Pearson's correlation was performed between the CEAP classification and ADI. Poisson regression analysis was performed to identify factors predicting for an increasing CEAP classification at presentation. Variables with P < .05 were deemed significant.

RESULTS

A total of 2346 patients underwent endovenous saphenous vein closure during the study period, of whom 7 were excluded because of a lack of follow-up data. The mean age was 60.4 ± 14.9 years, 65.9% were women, and 55.4% were White. Of the 2339 patients, 73.3% presented with an advanced CEAP class (≥3). The mean state ADI for the entire cohort was 4.9 ± 3.1. The percent change in the CEAP classification is an increase of 2% and 1% for every level increase in the state ADI for unadjusted (incidence rate ratio [IRR] = 1.02; P < .001) and adjusted (IRR = 1.01; P < .001) models, respectively. Black race has a 12% increased risk of a higher CEAP class on presentation compared with White race (IRR = 1.12; P = .005). Female sex had a 16% lower risk of a higher CEAP presentation compared with male sex (IRR = 0.84; P < .01).

CONCLUSIONS

Low socioeconomic status, Black race, and male sex are predictive of an advanced CEAP classification on initial presentation. These findings highlight the opportunity for improved mechanisms for identification of venous disease and at-risk patients before advanced disease progression in known disadvantaged patient populations.

Chronic Venous Insufficiency With Emphasis on the Geriatric Population

The underpinning of Chronic Venous Insufficiency (CVI) is valvular dysfunction, which manifests on a spectrum depending on the severity of insufficiency and duration of the disease. The mainstay of treatment relies on compression therapy of a proper type and intensity. In older adults, special consideration must be taken during the patient encounter to account for age-related factors. This review discusses the clinical presentation, diagnosis, and mimicking of CVI, focusing mainly on older adults. The epidemiology, risk factors, disease burden, and grave complications -- such as thrombosis and ulceration, are reviewed. The physiological impacts of CVI are described, providing the background for treatment strategies, including non-invasive, medical, and surgical therapies. The findings show advanced age to be an important risk factor contributing to CVI and that other age-related factors add to the risk of severe complications. Clinical assessments combined with objective measurements that assess localized skin water using tissue dielectric constant values or whole limb assessments may aid in the differential diagnosis. Furthermore, understanding the mechanism of action of compression therapy, the mainstay of CVI treatment, and its physiological impacts, allows for its informed use in geriatric patients with increased risks of potential compression-related side effects.

Natural History of Varicose Veins of the Legs

Objective To assess the natural history of saphenous and non-saphenous varicose veins using the results of the Bonn Vein Studies and data published in literature.

Methods We used the data of the Bonn Vein Studies (BVS) 1 and 2 to assess if preexisting non-saphenous varicose veins (NSVV) in persons who had no saphenous varicose veins (SVV) at baseline have an impact on the incidence of SVV during the follow-up of 6.6 years and vice versa. SVV where defined as tortuous or not-tortuous refluxing saphenous veins. The statistical evaluation was performed using SAS version 9.4 (SAS Institute, Cary, North Carolina). In addition, we performed a review of publications concerning the natural history of varicose veins (VV) using PubMed.

Results In the BVS the overall incidence of SVV within the follow-up time of 6.6 years was 8.0 % (n = 133 of 1661; 95 % CI: 6.8–9.4). 7.2 % (n = 107 of 1492) without VV in BVS 1 and 19.8 % (n = 26) of patients with preexisting NSVV developed SVV. The relative risk for the development of SVV in patients with preexisting NSVV was 2.44 (95% CI: 1.64–3.64) adjusted for age and sex. The overall incidence of NSVV was markedly higher with 13.3 % (n = 226 of 1661; 95 % CI: 11.8–15.1). During follow-up 148 patients (9.9 %) without VV in BVS 1 developed NSVV. 48.5 % (n = 78) of patients with preexisting SVV developed NSVV during follow-up. The relative risk for the development of NSVV in patients with preexisting SVV was 4.10 (95% CI: 3.26–5.16), adjusted for age and sex.

In published studies the development of VV is preceded by venous reflux. Initial VV may develop at any segment and the results from literature suggest that the location of VV and reflux at the time of the investigation depends on age. In younger individuals more distal location are reported with an ascending progression in the majority but also descending progression is possible.

Conclusions Based on the results of the Bonn Vein Studies 1 and 2 we could demonstrate, that preexisting SVV increase the risk of developing NSVV and preexisting NSVV increase the risk of developing SVV in a similar way. Venous reflux may initially occur in any segment of the venous system and may progress in antegrade and/or retrograde fashion. In younger adults initial VV seem to be localized more often in distal parts of the legs with an antegrade progression over time.

FEATURES OF RHEOVASOGRAPHIC PARAMETERS OF THE TIBIA IN VOLLEYBALL PLAYERS OF A HIGH LEVEL OF SKILL OF THE YOUTH AGE

OBJECTIVE

Aim of the work was to determine the peculiarities of rheographic parameters of the tibia in volleyball players of the general group and individual somatotypes.

PATIENTS AND METHODS

Materials and Methods: A comprehensive examination of 108 highly skilled volleyball players and 130 practically healthy girls aged between 16 and 20 years who did not play sports was conducted. The rheovasographic parameters of the tibia were determined using tetrapolar reocardiography on a computer diagnostic complex with the assessment of amplitude, time, and indicators of the ratio of amplitude and time rheovasographic parameters. A somatotypological study was conducted based on a calculated modification of the Heath-Carter method (1990) with the division of volleyball players and non-athletes into 4 constitutional groups: mesomorphic, ectomorphic, ecto-mesomorphic, and intermediate type.

RESULTS

Results: Significant differences in the value of individual amplitude and most tibia rheovasographic parameters between volleyball players and girls of the control group were revealed. In athletes, the amplitudes of the systolic, diastolic and rapid blood filling, the duration of the rheographic wave, the time of the ascending and descending parts of the rheogram and slow blood filling were statistically significantly higher. Somatotypological features of peripheral hemodynamic indicators were determined in volleyball players; the greatest differences in the indicators of regional blood circulation on the tibia were recorded for representatives of the ectomorphic somatotype; between volleyball players and non-athletes with ecto-mesomorphic somatotype, there was no significant difference in the value of all tibia rheovasographic parameters.

CONCLUSION

Conclusion: Systematic training and competitions lead to prominent changes in rheovasographic indicators of the tibia in young female volleyball players, which are manifested by a better state of capillary and venous blood filling of the tibia muscles, but at the same time a reduced speed of regional blood flow due to a reduced tone of the vascular wall of small and medium arteries.

Factors associated with chronic venous disease: study in 1,136 patients treated for varicose veins of the lower limbs in a specialized clinic

Background

Varicose veins are a highly prevalent condition in the general population, generating variable reasons for consultation that can alter the patient's quality of life, with prevalence and associated factors that vary in different series.

Objectives

To describe the epidemiological profile of patients who consulted for varicose veins by evaluating main symptoms and associated variables.

Methods

Between 2019 and 2020, 1,136 patients attending vascular surgery consultation in a specialized outpatient center were evaluated. Demographic variables, presented symptoms, complications, and associated factors, such as body mass index, parity and family history, were recorded.

Results

A total of 1136 patients were evaluated (79.8% women and 20.2% men), with a mean age of 53.51 years. The presence of symptoms was similar in men and women; the most frequent complications were ulcer, varicorrhage, and superficial venous thrombosis. Most patients showed CEAP 1, 2 and 3 (n = 909) and more than half were overweight or obese (n = 679) with a predominance of those classified as C4. Sixty-nine per cent had a positive family history of varicose veins. There was no difference between severity of varicose veins and time working in the standing or sitting position, but there was a greater presence of C5 or C6 ulcer among patients standing for more than 4 hours.

Conclusions

Describing the characteristics of patients with varicose veins helps to understand the disease and to focus efforts towards those who are more susceptible. The results of this research are similar to those found in other populations.

Contribution of the Elastic Component and Venous Wall Arterialization in Patients with Venous Reflux

Chronic venous disease (CVeD) is defined as a set of disorders affecting the venous system mainly manifested in the form of varicose veins. CVeD is characterized by a sustained venous hypertension, leading to a plethora of functional and structural changes in the vein that may cause valve incompetence and pathologic reflux. In turn, venous reflux aggravates the venous hypertension and enhances the progression of CVeD into the most advanced stages. Previous studies have proposed that there are several alterations in the venous wall preceding the valve dysfunction and venous reflux. Besides, it has also been identified that young patients with CVeD present premature aging and changes in the venous wall composition that may be related to the presence of venous reflux. In this context, the aim of the present study is to examine the possible pathophysiological role of elastic fibers and their precursors in the venous wall of patients with reflux in comparison to those without reflux, considering the variable age in both groups (<50 years and ≥50 years). We performed immunohistochemical and quantitative polymerase chain reaction (PCR) in order to assess the protein and gene expression of tropoelastin, fibrillin-1, fibulins 4 and 5, lysyl oxidase and lysyl oxidase like 1, respectively. In parallel, we assessed the elastin content through histological techniques (orcein stain) in this group of patients. Our results show significant changes in elastic fibers and their precursors in young patients with pathologic reflux when compared with elder patients with reflux and young patients without reflux. These variations suggest that the venous system of young patients with venous reflux appears to present an enhanced dynamism and arterialization of the venous wall, which may be associated with a premature aging and pathological environment of the tissue.

Understanding Chronic Venous Disease: A Critical Overview of Its Pathophysiology and Medical Management

Chronic venous disease (CVD) is a multifactorial condition affecting an important percentage of the global population. It ranges from mild clinical signs, such as telangiectasias or reticular veins, to severe manifestations, such as venous ulcerations. However, varicose veins (VVs) are the most common manifestation of CVD. The explicit mechanisms of the disease are not well-understood. It seems that genetics and a plethora of environmental agents play an important role in the development and progression of CVD. The exposure to these factors leads to altered hemodynamics of the venous system, described as ambulatory venous hypertension, therefore promoting microcirculatory changes, inflammatory responses, hypoxia, venous wall remodeling, and epigenetic variations, even with important systemic implications. Thus, a proper clinical management of patients with CVD is essential to prevent potential harms of the disease, which also entails a significant loss of the quality of life in these individuals. Hence, the aim of the present review is to collect the current knowledge of CVD, including its epidemiology, etiology, and risk factors, but emphasizing the pathophysiology and medical care of these patients, including clinical manifestations, diagnosis, and treatments. Furthermore, future directions will also be covered in this work in order to provide potential fields to explore in the context of CVD.

Drug-induced peripheral oedema: An aetiology-based review

Many drugs are responsible, through different mechanisms, for peripheral oedema. Severity is highly variable, ranging from slight oedema of the lower limbs to anasarca pictures as in the capillary leak syndrome. Although most often noninflammatory and bilateral, some drugs are associated with peripheral oedema that is readily erythematous (eg, pemetrexed) or unilateral (eg, sirolimus). Thus, drug-induced peripheral oedema is underrecognized and misdiagnosed, frequently leading to a prescribing cascade. Four main mechanisms are involved, namely precapillary arteriolar vasodilation (vasodilatory oedema), sodium/water retention (renal oedema), lymphatic insufficiency (lymphedema) and increased capillary permeability (permeability oedema). The underlying mechanism has significant impact on treatment efficacy. The purpose of this review is to provide a comprehensive analysis of the main causative drugs by illustrating each pathophysiological mechanism and their management through an example of a drug.

Possible Assessment of Calf Venous Pump Efficiency by Computational Fluid Dynamics Approach

Three-dimensional simulations of peripheral, deep venous flow during muscular exercise in limbs of healthy subjects and in those with venous dysfunction were carried out by a computational fluid-dynamics (CFD) approach using the STAR CCM + platform. The aim was to assess the effects of valvular incompetence on the venous calf pump efficiency. The model idealizes the lower limb circulation by a single artery, a capillary bed represented by a porous region and a single vein. The focus is on a segment of the circuit which mimics a typical deep vein at the level of the calf muscle, such as the right posterior tibial vein. Valves are idealized as ball valves, and periodic muscle contractions are given by imposing time-dependent boundary conditions to the calf segment wall. Flow measurements were performed in two cross-sections downstream and upstream of the calf pump. Model results demonstrate a reduced venous return for incompetent valves during calf exercise. Two different degrees of valvular incompetence are considered, by restricting the motion of one or both valves. Model results showed that only the proximal valve is critical, with a 30% reduction of venous return during calf exercise in case of valvular incompetence: the net flow volume ejected by the calf in central direction was 0.14 mL per working cycle, against 0.2 mL for simulated healthy limbs. This finding appeared to be consistent with a 25% reduction of the calf ejection fraction, experimentally observed in chronic venous disease limbs compared with healthy limbs.

The 2020 update of the CEAP classification system and reporting standards

The CEAP (Clinical-Etiology-Anatomy-Pathophysiology) classification is an internationally accepted standard for describing patients with chronic venous disorders and it has been used for reporting clinical research findings in scientific journals. Developed in 1993, updated in 1996, and revised in 2004, CEAP is a classification system based on clinical manifestations of chronic venous disorders, on current understanding of the etiology, the involved anatomy, and the underlying venous pathology. As the evidence related to these aspects of venous disorders, and specifically of chronic venous diseases (CVD, C2-C6) continue to develop, the CEAP classification needs periodic analysis and revisions. In May of 2017, the American Venous Forum created a CEAP Task Force and charged it to critically analyze the current classification system and recommend revisions, where needed. Guided by four basic principles (preservation of the reproducibility of CEAP, compatibility with prior versions, evidence-based, and practical for clinical use), the Task Force has adopted the revised Delphi process and made several changes. These changes include adding Corona phlebectatica as the C4c clinical subclass, introducing the modifier "r" for recurrent varicose veins and recurrent venous ulcers, and replacing numeric descriptions of the venous segments by their common abbreviations. This report describes all these revisions and the rationale for making these changes.

Influence of reimbursement policies on phlebological surgical practice in Belgium between 2007 and 2017

BACKGROUND

To date, it is unclear how treatment of patients with chronic venous disease (CVD) is influenced by national reimbursement systems. In Belgium, catheters or fibers used for endovenous thermal ablation (EVTA) are reimbursed only once in a lifetime. The potential impact of the Belgian public health insurance reimbursement policy on surgical practice in phlebology needs to be investigated.

METHODS

Billing data available from the Belgian National Institute for Health and Disability Insurance (NIHDI) were used for analyzing the distribution of specific surgical procedures for treating varicose veins and their relative use from 2007 to 2017. The potential influence of age, sex, social status and geographical origin of insured patients on surgical practice in Belgium were studied.

RESULTS

The annual intervention rate was 343 per 100,000 insured individuals for 2017 with a slight annual increase over the period 2007-2017 (+ 0.83% per year). Patients with limited resources, benefiting from a preferential reimbursement system, had a significantly lower intervention rate than those having the usual system (P<0.001). There was a large geographical variation in the use of care, ranging from 172 to 549 per 100.000 insured in 2017. The number of classic surgical procedures decreased (-6.17% per year) in the period 2015-2017) while EVTA, newly reimbursed in Belgium since 2012, increased during the same period (+ 3.6% per year). This evolution was more pronounced in the north (Flanders) than in the south (Wallonia) of the country. Bilateral treatment increased considerably from 2012 and stabilized at 33% of all surgical interventions in 2016 and 2017.

CONCLUSIONS

Available data of the NIHDI in Belgium highlight remarkable differences in the use of care for CVD, depending on social status and geographical origin of insured patients. The introduction of EVTA techniques has been adopted more rapidly in the north of the country and has led to an increased percentage of bilateral procedures.

Development of a Minimum Data Set Registry for Chronic Venous Insufficiency of the Lower Limbs

The purpose of this study was to develop a minimum data set (MDS) registry for the prevention, diagnosis and treatment of chronic venous insufficiency (CVI) of the lower limbs. We designed the instrument in two phases, comprising a literature review and an e-Delphi study to validate the content. We obtained a total of 39 documents that we used to develop a registry with 125 items grouped in 7 categories, as follows: Patient examination, venous disease assessment methods, diagnostic tests to confirm the disease, ulcer assessment, treatments to manage the disease at all its stages, patient quality of life, and patient health education. The instrument content was validated by 25 experts, 88% of whom were primary healthcare and hospital nurses and 84% had more than 10 years' experience in wound care. Using a two-round Delphi approach, we reduced the number of items in the MDS-CVI to 106 items. The categories remained unchanged. We developed an MDS for CVI with seven categories to assist healthcare professionals in the prevention, early detection, and treatment history of CVI. This tool will allow the creation of a registry in the primary care setting to monitor the venous health state of the population.

Predictors of exercise capacity in chronic venous disease patients

Objectives

The aim of this study was to determine predictors of exercise capacity and explore the relationship between exercise capacity, lower extremity performance level, pain, fatigue, physical activity, sleep quality, and quality of life in patients with chronic venous disease.

Methods

A total of 170 chronic venous disease patients who were referred to the Cardiovascular Surgery department were included. Assessment tools included the six-minute walk test for exercise capacity, repeated sit-to-stand test for lower limb performance level, Visual Analog Scale for pain, Fatigue Severity Scale for fatigue, Pittsburgh Sleep Quality Index for sleep quality, International Physical Activity Questionnaire for physical activity, and Venous Insufficiency Epidemiological and Economic Study’s Quality of Life questionnaire for quality of life.

Results

Exercise capacity was weakly and negatively correlated with body mass index (r = –0.391, p < 0.001), pain level (r = –0.268, p < 0.001), age (r = –0.355, p < 0.001), and fatigue severity (r = –0.141, p < 0.05). There was a weak positive correlation in walking distance with quality of life (r = –0.129, p < 0.05) and education level (r = 0.166, p < 0.05), whereas moderate positive correlation was observed between walking distance and lower limb performance level (r = 0.518, p < 0.001). Lower limb performance level was a significant predictor of exercise capacity, accounting for 50% of the variance.

Conclusions

Exercise capacity is an important determinant of morbidity. Therefore, there is a need to improve lower extremity performance and functional mobility in patients suffering from chronic venous disease.

Gravity force is not a sole explanation of reflux flow in incompetent great saphenous vein

OBJECTIVE

This study aimed to evaluate the impact of gravity, reservoir size, and competence of the ostial valve on venous reflux in different body positions.

METHODS

Our study included 61 lower limbs with primary incompetence of the great saphenous vein (GSV). The diameter of the GSV and its cross-sectional area, time-averaged mean velocity (TAMEAN), and reflux time (RT) were measured with duplex ultrasound with pulsed wave Doppler. Reflux volume (RV) and reflux volume flow rate (Q) were calculated. The measurements were carried out in three body positions: horizontal, A; seated upright with stretched legs, B; and vertical, C. Distal automatic cuff compression-decompression (120 mm Hg) was used as a provocation maneuver.

RESULTS

There was 100% occurrence of reflux in the patient positions B and C. Reflux was observed in 91.8% of cases in position A. All reflux parameters (TAMEAN, RT, Q, RV) and the size of the vein were significantly different in the three studied positions. The patient's height did not influence the magnitude of change in reflux parameters. All reflux parameters increased more significantly when the position changed from A to B than from B to C (TAMEAN, +103% and +37%; GSV diameter, +33% and +5%; RV, +408% and +65%, respectively).

CONCLUSIONS

Observed positional changes in reflux parameters suggest that gravitational forces are not a sole explanation for reflux flow in incompetent GSV. It is likely that the gravitational effect on venous flow is mediated by the changes in vein diameter and the total volume of the venous reservoir of the leg.

Refining diagnosis and management of chronic venous disease: Outcomes of a modified Delphi consensus process

Chronic venous disease (CVD) is a common condition with major health consequences that is associated with poor long-term prognosis, significant socioeconomic impact, disabling symptoms and reduced quality of life. To provide practical guidance for diagnosis and management of CVD, a Delphi panel of 5 experts in steering committee and 28 angiologists/vascular surgeons met with the major aim of providing a supplement for established national and international guidelines. A total of 24 statements were voted upon in two rounds, of which consensus was reached on 22 statements, indicating a high level of overall agreement. Consensus was reached on 7 of 8 statements relative to diagnosis (CEAP classification, diagnostic tools, QoL assessment, diagnostic imaging) and on 15 of 16 statements on management (conservative treatments, compressive therapy, pharmacological therapy, surgical treatment). The results of the consensus reached are discussed herein from which it is clear that diagnostic and management approaches utilising personalised therapies tailored to the individual patient should be favoured. While it is clear that additional studies are needed on many aspects of diagnosis and management of CVD, the present Delphi survey provides some key recommendations for clinicians treating CVD that may be useful in daily practice.

Major risk factors for chronic venous disease development in women: is childbirth among them?

Many studies have reported that Chronic venous disease (CVD) occurs more in females than males, due to pregnancy. The study was conducted over the period 2014-2015 at the Dermatovenereological clinic, Novi Sad, Serbia. We performed a cross-sectional study of 554 women. According to Clinical-Etiology-Anatomy-Pathophysiology (CEAP) staging, the sample was divided into three groups: Mild CVD (classes 1-3 by CEAP) - n = 72; Severe CVD (classes 4-6 by CEAP) - n = 122 and a Control (no CVD) - n = 360 patients. The age range of participants was 18 to 93 years (average 54.92 years). Most important CVD risk factors were examined in detail. Out of 554 examinees, 22.03% had severe CVD, and 12.99% had mild CVD. Bivariate analyses showed a significantly higher proportion of women who had deliveries in the severe CVD and mild CVD groups, compared with the control group. Other significantly related factors were older age, family history of varicose veins, standing job position and hypertension. After performing multiple logistic regression analysis, older age, standing job position and family history of varicose veins remained significant, while childbirth lost its significance. Our results suggest that childbirths are not associated with the occurrence of CVD.

Men present with higher clinical class of chronic venous disease before endovenous catheter ablation

BACKGROUND

Risk factors for chronic venous disease (CVD) have been widely reported in population health management. However, predisposing factors associated with patients treated for advanced stages of CVD have yet to be established. We examined the demographics and risk factors associated with advanced clinical presentation of CVD for patients referred for vein ablation.

METHODS

Retrospective analysis of our institutional Vascular Quality Initiative Varicose Vein Registry included endovenous laser treatment and radiofrequency ablation procedures at our tertiary institution, community hospital, and outpatient vein clinic between January 2015 and December 2016. All incompetent truncal veins were divided into two groups based on the Clinical, Etiology, Anatomy, and Pathophysiology clinical class of CVD: mild-moderate (C1-C3) and severe (C4-C6). The two groups were compared in terms of their demographics and medical comorbidities using univariate and multivariate analysis. Data analysis was conducted on SPSS 22.0 (IBM Corp, Armonk, NY).

RESULTS

During the study period, a total of 650 incompetent truncal veins were ablated. The mean age of patients was 58 years, and 73% were female. Severe CVD composed 21% of the cohort. Male sex was a risk for advanced CVD (odds ratio, 2.6; P < .001). Older age was also associated with severe CVD; the average age was 63 years for patients with advanced stage CVD vs 56 years for mild to moderate CVD (P < .001). Race, diabetes, body mass index, number of pregnancies, congestive heart failure, history of venous thromboembolism, current anticoagulation, and history of smoking or current smoking status did not affect the severity of CVD.

CONCLUSIONS

Among patients treated with vein ablation for superficial venous insufficiency, older age and male sex were associated with increased severity of advanced CVD. Despite the higher incidence of varicose veins among women, men are more likely to have clinically advanced CVD when they present for truncal vein ablation.

Clinical outcomes after varicose vein procedures in octogenarians within the Vascular Quality Initiative Varicose Vein Registry

BACKGROUND

Whereas chronic venous insufficiency and varicose veins (VVs) are a universally recognized problem, they are frequently underappreciated as major contributors to long-term morbidity in the elderly despite the increasing prevalence with age. Previous studies have demonstrated that chronic venous insufficiency and VV treatments in patients ≥65 years old yield an overall benefit; however, there have been few data as to whether octogenarians are undergoing these procedures and with what success. As such, our objectives were to investigate the procedures selected, to examine clinical outcomes after VV procedures in elderly patients ≥80 years old, and to explore complication rates (both systemic and leg specific) after VV procedures in patients ≥80 years old.

METHODS

We performed a retrospective review using the Vascular Quality Initiative Varicose Vein Registry of all VV procedures performed for ≥C2 disease from January 2015 to February 2017. We divided all procedures into three age groups: patients <65 years, patients ≥65 to 79 years, and patients ≥80 years. Statistical testing included χ² test for categorical variables and Student t-test for continuous variables. Two comparisons were performed: first, comparing patients <65 years old with patients ≥65 to 79 years old; and second, comparing patients ≥65 to 79 years old with patients ≥80 years old.

RESULTS

There were a total of 12,262 procedures performed, with 8608 procedures in the patients <65 years, 3226 in patients 65 to 79 years, and 428 procedures in patients ≥80 years. A total of 22,050 veins were treated during the 12,262 procedures. Almost half of procedures (46.51%; n = 5703) had only one vein treated during a single procedure. Between age groups, the percentage of one vein treated increased as the patient's age increased, ranging from 45.39% (n = 3875) for patients <65 years to 48.55% (n = 1555) for patients between 65 and 79 years and 64.08% (n = 273) for patients ≥80 years. Patients in the group ≥80 years had an overall lower average body mass index and were more likely to be receiving anticoagulation and to undergo truncal procedures alone compared with the other groups. The group ≥80 years had a significant improvement in both Venous Clinical Severity Score (4.37 ± 4.16; P < .001) and patient-reported outcomes (8.79 ± 7.27; P < .001) from before to after the procedure. Overall complications were low in all age groups. The octogenarians had no higher risk of systemic complications.

CONCLUSIONS

Vascular specialists are performing VV procedures in octogenarians and are more likely to perform truncal only therapy. In addition, octogenarians have statistically significant improvement of Venous Clinical Severity Score and patient-reported outcomes with a low risk of complications despite more advanced venous disease at presentation.

Plasma concentration of selected biochemical markers of endothelial dysfunction in women with various severity of chronic venous insufficiency (CVI)-A pilot study

BACKGROUND

Although the endothelial dysfunction is considered to be implicated in the pathogenesis of chronic venous insufficiency (CVI) the endothelial status in patients with venous disorders is still not fully evaluated. Therefore the aim of the study was to measure the concentration of selected markers of endothelial dysfunction: von Willebrand factor (vWf), soluble P-selectin (sP-selectin), soluble thrombomodulin (sTM) and soluble VE-cadherin (sVE-cadherin) in CVI women who constitute the most numerous group of patients suffering from venous disease.

MATERIALS AND METHODS

Forty four women with CVI were involved in the study and divided into subgroups based on CEAP classification. Concentration of vWf, sP-selectin, sTM and sVE-cadherin were measured and compared with those obtained in 25 healthy age and sex-matched women.

RESULTS

It was found that the concentration of sTM increased and sVEcadherin decreased along with disease severity in CVI women. A significant rise of sTM was observed especially in CVI women, with the highest inflammation status reflected by hsCRP or elastase concentration, and in CVI women with a high oxidative stress manifested by an increased plasma MDA. A significant fall of circulating sVE-cadherin was reported in CVI women with moderate to highest intensity of inflammation and oxidative stress. There was no change in vWF and sP-selectin concentration at any stage of CVI severity.

CONCLUSIONS

The results of the present study demonstrate the presence of endothelial dysfunction in women suffering from CVI which seems to progress with the disease severity and may be associated with inflammation and enhanced oxidative stress.

Analysis of the dynamics of venous blood flow in the context of lower limb temperature distribution and tissue composition in the elderly

OBJECTIVE

The elderly are particularly vulnerable to degenerative diseases, such as circulatory and respiratory system and vascular system diseases. The objective of this study was therefore to evaluate the distribution of temperature and the dynamics of venous blood flow in the lower limbs (LLs) and to assess the interdependence of these parameters in terms of the somatic components in males and females participating in activities at the University of the Third Age.

MATERIALS AND METHODS

The study included 60 females (mean age 67.4 years) and 40 males (mean age 67.5 years). A body composition assessment was performed using the bioimpedance technique - Tanita BC-418MA. The following parameters were examined: fat%, fat mass, fat-free mass, and total body water. The minimal, maximal, and mean temperature values and their distributions were examined using infrared thermographic camera VarioCAM Head. Measurements of the venous refilling time and the work of the LL venous pump were examined using a Rheo Dopplex II PPG.

RESULTS

In males, the mean value of the right LL temperature was 30.58 and the mean value of the left LL was 30.28; the P-value was 0.805769. In females, the mean value of the right LL temperature was 29.58 and the mean value of the left limb was 29.52; the P-value was 0.864773. In males, the right limb blood flow was 34.17 and the left limb blood flow was 34.67; the P-value was 0.359137. In females, the right limb blood flow was 26.89 and the left limb blood flow was 26.09; the P-value was 0.796348.

CONCLUSION

Research results showed that the temperature distribution and the dynamics of blood flow are not significantly different between the right and left extremities in both males and females. However, significant temperature differences were found between the gender groups. Significantly higher temperature values in both the right and left extremities were recorded in males than in females.

Prophylactic GSV surgery in elderly candidates for hip or knee arthroplasty

Aging is one of the major risk factors for varicose veins. The same is for Knee and Hip Osteoarthritis. Most of the patients undergoing to Hip (THA) or Knee (TKA) arthroplasty are over sixteen. Varicose veins, excluding thrombophilia, are the most significant risk factors for VTE after THA and TKA. This study investigates on the usefulness of prophylactic treatment of GSV insufficiency in elderly patients undergoing to orthopedic surgery. A retrospective study enrolling 44 over-sixty five patients, undergoing to TKA or THA. 24 patients underwent to traditional surgery and 20 to EVLA. The presence of evident varicosities and/or a saphenic reflux lasting > 500 ms has been considered as operability criterion. Both in surgery and EVLA group has been performed the ablation of visible varicosities and only saphenic refluxing traits.

RESULTS

1 case of symptomatic DVT was recorded after arthroplasty. A statistically significant difference (p = 0.006) of recovery time between surgery and EVLA groups has been detected. There is not a statistically significant difference in long-term recurrence rate between surgery and EVLA.

CONCLUSIONS

It is useful to program GSV surgery, before treat hip or knee. This study showed a 50% decrease in the incidence of postoperative DVT.

[CHANGES IN RHEOGRAPHIC INDICATORS OF SHIN IN ATHLETES OF DIFFERENT KINDS OF SPORTS]

We determined the changes of time, amplitude and derivatives of these indicators of rheovasograms of shin in sportsmen of youth age and high level of skills engaged in volleyball, athletics and wrestling with sports experience at least 3 years. We determined significant differences in the value of time, amplitude and derivatives of these indicators ofrheovazograms of shin in males youth age, depending on the impact of intense exercise. The volleyball players compared to youth who do not exercise, reliably large values of the overall tone of the arteries (11,2%), arteries of large diameter (8,2%), arteries of medium and small diameters (13,5%), time ascending part of rheovazograms (2%) and a slow passage (5,9%) and less dycrotycs index (17%), duration ofrheographic wave (3,7%), time descending part of rheovazograms (10%). The persons of control group had higher values of baseline impedance than wrestlers (9,9%) and athletes (13,7%) and all amplitude indicators rheograms of the shin than athletes (average 12-15%) and wrestlers (22-23%). The size and volume of blood flow to the arteries of the extremities adapted to the metabolic needs of the relevant muscles. In volleyball players compared to the athletes, a lower duration of rheographic wave (10%), time of downlink part of the rheograms (12,7%), the base impedance (17,2%), amplitude of the systolic wave (17%) and rapid blood filling (21%), all indicators tone of arteries (12,2-16,9%) and greater value of time of rising part of rheograms (3,5%) and slow blood filling (5,9%). Wrestlers compared to the athletes have a lower duration of rheographic wave (6,1%), time of downlink part of the rheograms (6,1%), the amplitude of the systolic wave (9,3%), compared with volleyball players set lower values of average speed of fast blood filling (15,6%), tone of arteries with different diameters (15-16,5%), all amplitude indicators (20-28%), time slow blood filling (9,7%), ascending parts rheogram (10,3%). Thus, the level ofphysical activity and especially muscle activity has a significant effect on the performance of regional blood flow.

Obesity and lower limb venous disease - The epidemic of phlebesity

Introduction Lower limb venous disease affects up to one half, and obesity up to one quarter, of the adult population. Many people are therefore affected by, and present to health services for the treatment of both conditions. This article reviews the available evidence of pathophysiological and clinical relationship between obesity and varicose veins, chronic venous insufficiency and ulceration and deep vein thrombosis. Methods A literature search of PubMed and Cochrane libraries was performed in accordance with PRISMA statement from 1946 to 2015, with further article identification from following cited references for articles examining the relationship between obesity and venous disease. Search terms included obesity, overweight, thrombosis, varicose veins, CEAP, chronic venous insufficiency, treatment, endovenous, endothermal, sclerotherapy, bariatric surgery and deep vein thrombosis. Results The proportion of the population suffering from lower limb venous disease and obesity is increasing. Obesity is an important risk factor for all types of lower limb venous disease, and obese patients with lower limb venous disease are more likely to be symptomatic as a result of their lower limb venous disease. The clinical diagnosis, investigation, imaging and treatment of lower limb venous disease in obese people present a number of challenges. The evidence base underpinning medical, surgical and endovenous management of lower limb venous disease in obese people is limited and such treatment may be associated with worse outcomes and increased risks when compared to patients with a normal body mass index. Conclusion Lower limb venous disease and obesity are both increasingly common. As such, phlebologists will be treating ever greater numbers of obese patients with lower limb venous disease, and clinicians in many other specialties are going to be treating a wide range of obesity-related health problems in people with or at risk of lower limb venous disease. Unfortunately, obese people have been specifically excluded from many, if not most, of the pivotal studies. As such, many basic questions remain unanswered and there is an urgent need for research in this challenging and increasingly prevalent patient group.

Symptoms in patients with skin changes due to chronic venous insufficiency often lead to emergency care service: an Italian observational study

Chronic venous insufficiency (CVI) is the most advanced form of chronic venous disease (CVD), and is often associated with skin changes such as hyperpigmentation, eczema, lipodermatosclerosis and venous skin ulceration that cause discomfort, pain, sleep disturbances, absenteeism in the workplace, disability and deteriorated quality of life (QoL). The purpose of this study is to evaluate the prevalence of CVI and skin changes in patients who turn to Continuous Assistance Services due to the presence of disturbing symptoms of their condition. Data were evaluated by consulting the medical records, during a 16-month period, available with three Continuous Assistance Services of the Italian territory. The overall population of the referring centres consisted of 1186 patients [739 females (62·31%) and 447 males (37·69%)]. Seventy-nine patients (6·66%) consulted the emergency unit for venous symptoms related to CVD. Patients with more severe disease (CVI, categories C4-C6) represented the majority accounting for 60·75%, while patients with moderate disease (C3) accounted for 35·44% and patients with mild disease (C1-C2 stages) accounted for 3·79%. The main finding of this study is that despite CVI not being a disease that commonly requires medical emergency/urgency intervention, patients with CVI, especially in advanced stage with skin changes, may turn to Continuous Assistance Service for treating bothersome symptoms related to their condition.

The influence of age and gender on venous symptomatology. An epidemiological survey in Belgium and Luxembourg

Aim

The aim of this study is to measure the incidence of the symptoms in patients with chronic venous disease (CVD) and to look for the influence of age on the severity of symptoms for both genders.

Materials and methods

A survey was carried out in Belgium and Luxembourg between May and September 2013. Patient recruitment was done by 406 general practitioners (GPs). Each GP screened 10–20 consecutive patients older than 18 years. Inquiries were made regarding the presence of symptoms and possible signs of CVD. Patients with diagnosed CVD filled out a questionnaire including a quality of life score (CIVIQ-14). These data were converted into a CIVIQ Global Index Score (GIS). Statistical analysis was performed in order to calculate the effect of age and gender on the number of symptoms and the estimated probabilities of having CVD.

Results

Totally 6009 patients were included in this survey. The mean age was 53.4 years. Of all, 61.3% of the patients have CVD (C1-C6). Of all, 64.7% of patients were symptomatic. Age and female gender were major risk factors for developing CVD. Most common symptoms were ‘heavy legs’ (70.4%), pain (54.0%), and sensation of swelling (52.7%). The number of symptoms increases with age ( p < 0.001). Female patients have significantly more symptoms in comparison with male patients in all age groups. In both females and males, age is negatively correlated with GIS score ( p < 0.001). The estimated probability of having CVD was significantly higher for woman compared to men and increases with age for both gender.

Conclusion

CVD is a very common progressive disease with age as a major risk factor. Increasing age results in a higher C-classification, more symptoms, and a lower GIS score (quality of life). Female gender interacts significantly with age and results in a more advanced stage of CVD.

The impact of obesity on venous insufficiency

Association between chronic venous disease and obesity has recently been studied, with indications that it may worsen in obese patients. The aim of study was to correlate clinical classes of chronic venous disease according to Clinical Etiology Anatomy Pathophysiology (CEAP) classification and body mass index, as well as to compare the severity of chronic venous disease in obese and nonobese patients. This retrospective cross-sectional prevalence study was conducted at the Maringá State University and Belczak Vascular Center along a period of 2 years, consisting of a random sample of 482 patients with complaints compatible with chronic venous disease. Data obtained from patient’s files included gender, age, weight and height (for calculating body mass index), and clinical class (C) of chronic venous disease according to CEAP classification. Statistical analysis included Spearman’s correlation coefficient, Chi-square test (for comparing frequencies), and Student’s t-test (for comparing means). Significant positive correlation between body mass index and clinical classes was established for women (0.43), but not for men (0.07). Obesity (body mass index ≥ 30.0) was significantly more frequent in patients with chronic venous disease in clinical classes 3 (p < 0.001) and 4 (p = 0.002) and less frequent in patients with chronic venous disease in clinical class 1 (p < 0.001). This study evidenced significant correlation between body mass index and clinical classes of chronic venous disease in women, but not in men. It also corroborated the negative impact of obesity on the clinical severity of chronic venous disease.

Radiofrequency Ablation as First-line Treatment of Varicose Veins

Endovascular radiofrequency ablation is a minimally invasive method to safely treat symptomatic refluxing varicose veins. A retrospective chart review was used to determine patient demographics, disease severity, treatment algorithm, and outcome in patients who underwent radiofrequency ablation of symptomatic refluxing veins that had failed conservative management. Statistical analysis was done using GraphPad Demo Version (San Diego, CA). Two hundred forty-one limbs in 179 patients (average age, 53 years; 73% females, 27% males) were treated. Preprocedure Clinical Etiological Anatomic and Pathologic (CEAP) scores were C2s: 236, C3s: 4, and C5s:1. Procedures were performed in the office using tumescent anesthetic; all patients could ambulate immediately after the procedure. Postprocedure total occlusion (TO) rate was seen in 93 per cent of limbs (223 limbs) at 3 months and 91 per cent of limbs (220 limbs) at 12 months posttreatment. No relationship was found between patients who did not have total occlusion and age, sex, diameter of veins, CEAP scores, preoperative reflux time, and volume of tumescent anesthetic ( P > 0.05). The VNUS procedure is an in-office, minimally invasive procedure with a low complication rate and quick recovery. Total occlusion rates are high and there is improvement in disease severity after treatment.

Factors related to venous ulceration: a cross-sectional study

The aim of the study was to determine the factors related to venous ulceration. Patients with venous ulceration (278 patients) were compared with 1401 patients in other categories of clinical classification of venous disease (clinical, etiologic, anatomic, and pathophysiological [CEAP]). Demographic, anthropometric, and clinical data were collected. Univariate and multivariate logistic regression analyses were used. According to multivariate analyses, risk factors for venous ulceration were age, male sex, personal history of superficial and deep venous thrombosis, diabetes, high blood pressure, skeletal or joint disease in the legs and emphysema or chronic obstructive pulmonary disease, higher body mass index and physical inactivity, parental history of ankle ulcer as well as reflux in deep and perforator veins, deep obstruction, and combination of reflux and obstruction. It seems reasonable to pay special attention to patients in whom the postulated risk factors for venous ulceration are present.

Clinical and anatomic outcomes of endovenous radiofrequency ablation performed on symptomatic small-diameter great saphenous veins

OBJECTIVE

The efficacy of radiofrequency ablation (RFA) for symptomatic varicose veins is well established. Alternatively, there is less consensus and little data on outcomes when treating great saphenous veins (GSV) of small diameter (≤5 mm). The purpose of this study is to assess clinical and anatomical outcomes of RFA on symptomatic patients with small GSV.

METHODS

A retrospective analysis was performed on our symptomatic patients who received RFA of incompetent GSV without any concomitant adjunctive procedures between January 2008 and December 2011. Limbs with GSV thigh diameter ≤5 mm and >5 mm on duplex while standing were subject to review. Clinical success was defined as an improvement in Venous Clinical Severity Score (VCSS) at 3 months. Anatomic success was defined as absence of venous flow ≤3 cm distal to the saphenofemoral junction on duplex ultrasound examination. Changes in CEAP class were noted.

RESULTS

In 307 patients, 55 limbs in 44 patients met inclusion criteria. Baseline median VCSS was 4 (interquartile range [IQR], 4, 5) for those patients with diameter ≤5 mm. Clinical success was seen in 83% of limbs at 3 months with a median VCSS change of -2 (IQR, -3, -1). None of the treated limbs had phlebectomy for symptomatic refluxing GSV varicosities prior to 3-month follow up. One phlebectomy was performed for cosmesis at 78 days postprocedure. Anatomic success was achieved in 96% of limbs at 3 months. Baseline median CEAP was 2 (IQR, 2, 2). The median CEAP change at 3 months was 0 (IQR, -1, 0). One patient experienced thrombus extension into the saphenofemoral junction at 4 days.

CONCLUSIONS

In our experience, RFA of symptomatic small-diameter GSV provides comparable clinical and anatomic outcomes to that of current published data. Our findings suggest that these patients benefit clinically from RFA.

Body mass index and primary chronic venous disease--a cross-sectional study

OBJECTIVES

This study aims to investigate whether overweight and obesity are related to the clinical (C) category of clinical, etiologic, anatomic and pathophysiologic (CEAP) classification of chronic venous disease (CVD).

DESIGN

A cross-sectional study.

MATERIALS AND METHODS

The study was conducted in Serbia, in the year 2011. Men and women aged >18 years, consecutively coming to venous specialists because of venous problems in the legs, were included in the study. Patients demographic, anthropometric and clinical data were collected. For the analysis, univariate and multivariate logistic regressions were used.

RESULTS

The study comprised 1116 subjects with primary CVD, 384 (34.4%) men and 732 (65.6%) women. Among them 464 (41.6%) were normal-weight patients (body mass index (BMI) < 25.0 kg m(-2)), 476 (42.7%) were overweight (BMI = 25.0-29.9 kg m(-2)) and 176 (15.8%) were obese (BMI ≥ 30.0 kg m(-2)). According to multivariate analysis, the CEAP C category of CVD was significantly more advanced in overweight and obese patients, the association being more pronounced in obese. Compared groups did not differ in the presence of venous reflux. In univariate analysis, venous obstruction was related to overweight and obesity but this association did not substantially affect the relationship between obesity and CEAP C categories of CVD.

CONCLUSION

The CEAP C categories of CVD were significantly related to overweight and obesity, and this association was independent of age, sex and some other postulated risk factors.

Trophic ulcers-Practical management guidelines

The management of patients with trophic ulcers and their consequences is difficult not only because it is a recurrent and recalcitrant problem but also because the pathogenesis of the ulcer maybe different in each case. Methodically and systematically evaluating and ruling out concomitant pathologies helps to address each patient's specific needs and hence bring down devastating complications like amputation. With incidence of diabetes being high in our country, and leprosy being endemic too the consequences of neuropathy and angiopathy are faced by most wound care specialists. This article presents a review of current English literature available on this subject. The search words were entered in PubMed central and appropriate abstracts reviewed. Relevant full text articles were retrieved and perused. Cross references from these articles were also reviewed. Based on these articles and the authors’ experiences algorithms for management have been presented to facilitate easier understanding. It is hoped that the information presented in this article will help in management of this recalcitrant problem.
