Abstract
BACKGROUND Increasing the levels of physical activity (PA) is widely recommended for people with chronic venous insufficiency (CVI). However, studies investigating the patterns of PA and adherence to PA guidelines using objective measures are lacking. OBJECTIVE The primary aim was to examine the patterns of PA and adherence to PA guidelines among patients with CVI. A secondary aim was to identify whether adherence to PA recommendations differed according to patients' sociodemographic and clinical characteristics. METHODS This cross-sectional study included 96 patients with CVI with Clinical-Etiology-Anatomy-Pathology (CEAP) C3 to C6 (69.1% women 59 ± 11 years; 51.5% C5-C6 on CEAP classification). Objective time spent in PA was measured by a triaxial accelerometer. To examine adherence to PA guidelines, patients were grouped as meeting (or) the recommendations if they had at least 150 min/week of moderate to vigorous PA. Sociodemographic and clinic characteristics were obtained by self-report. Binary logistic regression was employed to examine whether sociodemographic and clinical characteristics were associated with adherence to PA guidelines. T-tests were employed to compare PA levels at different intensities according to patients' age. RESULTS Patients spent an average of 311.4 ± 91.5 min/week, 42.1 ± 28.0 min/week, and 19.8 ± 17.8 min/week in low-light PA, high-light PA, and moderate-to-vigorous PA, respectively. The proportion of patients meeting PA recommendations was 36.2%, and older patients had lower odds (OR = 0.94; 95%CI: 0.89 to 0.99). Additional analysis reinforced that by showing lower time in high-light PA (51.2 ± 30.0 min/day vs. 31.9 ± 21.8 min/day; p = .001) and moderate-to-vigorous PA (24.3 ± 15.8 min/day vs. 14.8 ± 18.8 min/day; p = .012) among older patients than their peers younger. CONCLUSION Our findings showed that 36,2% of CVI patients met PA recommendations, with lower odds found among older patients. Public health interventions to enhance PA engagement among CVI patients should prioritize those who are older.

Abstract
Patient compliance and therapeutic precision of compression textiles (CTs) are frequently limited by the inaccurate pressure distributions along biological bodies in physical-based compression therapy. Therefore, the biomechanical influences of physiological tissue material characteristics of lower extremities on compression generations of CTs need to be explored systematically to improve pressure management efficacy. In this study, we developed three-dimensional (3D) homogenous finite element (FE) CT-leg systems to qualitatively compare the pressure diversities along lower limbs with different biomaterial tissue properties under each external compression level. Simultaneously, through the obtained leg circumferential displacement, a contact analysis model was applied to quantitatively explore the impact mechanisms of soft leg indentations on the pressure performance of CTs. Based on the experimental validation study, the proposed FE systems could be efficiently utilized for compression performance prediction (error ratio: 7.45%). Through the biomechanical simulation and theoretical calculations, the tissue stiffness characteristics of applied bodies showed significant correlations (p < 0.05) with the body circumferential displacements but no correlations (p > 0.05) with pressure delivery differences of CTs. This study facilitates the pressure fit design principle and leg mannequin material selection guidance for the development and experimental assessment of CTs. It also provides effective simulation methods for pressure prediction and property parametric optimization of compression materials.

J Vasc Surg Venous Lymphat Disord 2024; 12:101864. [PMID: 38518986 DOI: 10.1016/j.jvsv.2024.101864] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Revised: 01/31/2024] [Accepted: 02/22/2024] [Indexed: 03/24/2024]
Abstract
OBJECTIVE Endothermal heat-induced thrombosis (EHIT) is a potential complication of radiofrequency ablation (RFA). Data on effective prophylaxis of EHIT are limited. In 2018, a high-volume, single institution implemented strategies to decrease the incidence of EHIT, including a single periprocedural prophylactic dose of low-molecular-weight heparin to patients with a great saphenous vein (GSV) diameter of ≥8 mm or saphenofemoral junction (SFJ) diameter of ≥10 mm and limiting treatment to one vein per procedure. The size threshold was derived from existing literature. The study objective was to evaluate the effects of these institutional changes on thrombotic complication rates after RFA. METHODS A retrospective cohort control study was conducted using the Vascular Quality Initiative database. Data were collected for patients who underwent RFA with a GSV diameter of ≥8 mm or SFJ diameter of ≥10 mm from January 2015 to July 2022. The clinical end points were thrombotic complications (ie, thrombophlebitis, EHIT, deep vein thrombosis) and bleeding complications. Patient demographic and procedural variables were included in the analysis, and significant variables after univariable logistic regression were included in a multivariable logistic regression. RESULTS After the policy change, the overall vein center EHIT rate decreased from 2.6% to 1.5%, with a trend toward significance (P = .096). The inclusion criterion of a GSV diameter of ≥8 mm or an SFJ diameter of ≥10 mm yielded 845 patients, of whom 298 were treated before the policy change and 547 after. There was a significant reduction in the rate of EHIT classified as class ≥III (2.34 vs 0.366; P = .020) after the institutional changes. Treatment of two or more veins and an increased vein diameter were associated with an increased risk of EHIT (P = .049 and P < .001, respectively). No significant association was found between periprocedural anticoagulation and all-cause thrombotic complications or EHIT (P = .563 and P = .885, respectively). CONCLUSIONS The institutional policy changes have led to lower rates of EHIT, with a reduction in severe EHIT rates in patients with an ≥8-mm diameter GSV or a ≥10-mm diameter SFJ treated with RFA. Of the changes implemented, restricting treatment to one vein was associated with a reduction in severe EHIT. No association was found with periprocedural low-molecular-weight heparin, although a type 2 error might have occurred. Alternative strategies to prevent thrombotic complications should be explored, such as increasing the dosage and duration of periprocedural anticoagulation, antiplatelet use, and nonpharmacologic strategies.

Abstract
OBJECTIVE The goal of this study was to analyze trends in treatment access for chronic superficial venous disease and to identify disparities in care. METHODS This retrospective study was exempt from institutional review board approval. The American College of Surgeon National Surgical Quality Improvement Program database was used to identify patients who underwent vein stripping (VS) and endovenous procedures for treatment of chronic superficial venous disease. Endovenous options included radiofrequency ablation (RFA) and laser ablation. Data was available from 2011 to 2018 and demographic information was extracted for each patient identified by Current Procedural Terminology codes. For all racial and ethnic groups, trend lines were plotted, and the relative rate of change was determined within each specified demographic. RESULTS There were 21,025 patients included in the analysis. The overall mean age was 54.2 years, and the majority of patients were female (64.8%). In total, 27.9%, 55.2%, and 16.9% patients underwent VS, RFA, and laser ablation, respectively. Patients who received laser ablation were older (P < .001). Hispanic ethnicity was associated with significantly lower odds of receiving endovascular thermal ablation (EVTA) over VS (odds ratio [OR], 0.71; 95% confidence interval [CI], 0.64-0.78; P < .001). American Indian/Alaska Native patients were more likely to receive EVTA over VS (OR, 4.02; 95% CI, 2.48-6.86); similarly, Native Hawaiian/Pacific Islander patients were more likely to receive EVTA over VS, although this difference was not statistically significant (OR, 1.44; 95% CI, 0.93-2.27). On multinomial regression, Hispanic patients were less likely to receive RFA over VS, whereas American Indian/Alaskan Native patients were more likely to receive RFA over VS. In all racial and ethnic groups, the percentage of endovenous procedures increased, whereas vein stripping decreased. CONCLUSIONS Based on a hospital-based dataset, demographic indicators, including age, sex, race, and ethnicity, are associated with differences in endovenous treatments for chronic superficial venous insufficiency suggesting disparities in obtaining minimally invasive treatment options among certain patient groups.

Factors associated with lack of clinical improvement after vein ablation in the vascular quality initiative. J Vasc Surg Venous Lymphat Disord 2024; 12:101884. [PMID: 38552954 DOI: 10.1016/j.jvsv.2024.101884] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 03/10/2024] [Accepted: 03/19/2024] [Indexed: 04/20/2024]
Abstract
BACKGROUND Insurance companies have adopted variable and inconsistent approval criteria for chronic venous disease (CVD) treatment. Although vein ablation (VA) is accepted as the standard of care for venous ulcers, the treatment criteria for patients with milder forms of CVD remain controversial. This study aims to identify factors associated with a lack of clinical improvement (LCI) in patients with less severe CVD without ulceration undergoing VA to improve patient selection for treatment. METHODS We performed a retrospective analysis of patients undergoing VA for CEAP C2 to C4 disease in the Vascular Quality Initiative varicose veins database from 2014 to 2023. Patients who required intervention in multiple veins, had undergone prior interventions, or presented with CEAP C5 to C6 disease were excluded. The difference (Δ) in venous clinical severity score (VCSS; VCSS before minus after the procedure) was used to categorize the patients. Patients with a ΔVCSS of ≤0 were defined as having LCI after VA, and patients with ≥1 point decrease in the VCSS after VA (ΔVCSS ≥1) as having some benefit from the procedure and, therefore, "clinical improvement." The characteristics of both groups were compared, and multivariable regression analysis was performed to identify factors independently associated with LCI. A second analysis was performed based on the VVSymQ instrument, which measures patient-reported outcomes using five specific symptoms (ie, heaviness, achiness, swelling, throbbing pain, and itching). Patients with LCI showed no improvement in any of the five symptoms, and those with clinical improvement had a decrease in severity of at least one symptom. RESULTS A total of 3544 patients underwent initial treatment of CVD with a single VA. Of the 3544 patients, 2607 had VCSSs available before and after VA, and 420 (16.1%) had LCI based on the ΔVCSS. Patients with LCI were more likely to be significantly older and African American and have CEAP C2 disease compared with patients with clinical improvement. Patients with clinical improvement were more likely to have reported using compression stockings before treatment. The vein diameters were not different between the two groups. The incidence of complications was overall low, with minor differences between the two groups. However, the patients with LCI were significantly more likely to have symptoms after intervention than those with improvement. Patients with LCI were more likely to have technical failure, defined as vein recanalization. On multivariable regression, age (odds ratio [OR], 1.01; 95% confidence interval [CI], 1.00-1.02) and obesity (OR, 1.47; 95% CI, 1.09-2.00) were independently associated with LCI, as was treatment of less severe disease (CEAP C2; OR, 1.82; 95% CI, 1.30-2.56) compared with more advanced disease (C4). The lack of compression therapy before intervention was also associated with LCI (OR, 6.05; 95% CI, 4.30-8.56). The analysis based on the VVSymQ showed similar results. CONCLUSIONS LCI after VA is associated with treating patients with a lower CEAP class (C2 vs C4) and a lack of compression therapy before intervention. Importantly, no significant association between vein size and clinical improvement was observed.

Abstract
Chronic superficial venous disease, including superficial venous insufficiency, superficial venous thrombosis, and aneurysms, are prevalent conditions that affect millions of individuals worldwide. With chronic venous insufficiency specifically, the advent of office-based minimally invasive procedures in recent decades has significantly expanded access to outpatient treatment. However, as venous insufficiency is rarely life- or limb-threatening, the clinical diagnosis, diagnostic evaluation, and treatment indications should be considered carefully when recommending elective intervention. Appropriateness of care guidelines intend to aid providers and patients in the decision-making process, based on the available evidence in the scientific literature, to select the best care for the patient when treating their superficial venous disease.

Abstract
BACKGROUND Comprehensive vascular care includes both arterial and venous disease management. However, operative training in venous disease is often significantly overshadowed by arterial procedures, despite the public health burden of acute and chronic venous disease. The purpose of this study is to evaluate the case-mix and volume of venous procedures performed by graduating integrated vascular surgery residents and fellows in the United States. METHODS Accreditation Council for Graduate Medical Education national operative log reports were compiled for graduating integrated VSR (vascular surgery residency) and traditional vascular surgery fellowship (VSF) trainees from academic years 2013 to 2022. Only cases categorized as "surgeon fellow", "surgeon chief", or "surgeon junior" were included. Linear regression analysis was utilized to evaluate trends in case-mix and volume. RESULTS Over the 10-year study period, total vascular cases increased for both VSR (mean 870.5 ± 9.3 cases, annual change +9.5 cases/year, R2 = 0.77, P < 0.001) and VSF (mean 682.1 ± 6.9 cases, annual change +6.7 cases/year, R2 = 0.85, P < 0.001) trainees. Concurrently, the proportion of venous cases in the VSR group decreased from 12.5% to 7.3% (annual change -3.7 cases/year, R2 = 0.72, P < 0.001). VSR trainees experienced an annual decrease in 4 of the top 5 venous case types performed, including venous angioplasty/stenting (-1.6 cases/year, P = 0.002), vena cava filter placement (-0.9 cases/year, P = 0.002), endoluminal ablation (-0.2 cases/year, P = 0.47), diagnostic venography (-1.7 cases/year, P < 0.001), and varicose vein treatment (-1.0 cases/year, P < 0.001). Venous cases proportions also decreased in the VSF group from 8.4% to 6.2% (annual change -2.2 cases/year, R2 = 0.54, P = 0.002). VSF trainees experienced an annual decrease in 4 of the top 5 venous case types, including venous angioplasty/stenting (-1.5 cases/year, P = 0.003), diagnostic venography (-1.2 cases/year, P < 0.001), vena cava filter placement (-0.2 cases/year, P = 0.44), endoluminal ablation (-0.6 cases/year, P < 0.001), and varicose vein treatment (-0.1 cases/year, P = 0.04). Both VSR and VSF trainee groups graduated with fewer than 5 cases for each of the following venous procedures-percutaneous mechanical thrombectomy, venous thrombolysis, open venous reconstruction, sclerotherapy, venous embolectomy, portal-systemic shunting, venous ulceration treatment, and arteriovenous malformation treatment. CONCLUSIONS Current vascular residents and fellows have limited exposure to venous procedures, in part due to a proportional decline in venous cases. More robust venous operative experience is needed during surgical training. Further studies are needed to understand whether this discrepancy in venous and arterial training impacts career progression and patient outcomes.

Effect of junctional reflux on the venous clinical severity score in patients with insufficiency of the great saphenous vein (JURY study). J Vasc Surg Venous Lymphat Disord 2024; 12:101700. [PMID: 37956904 PMCID: PMC10939725 DOI: 10.1016/j.jvsv.2023.101700] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Revised: 09/29/2023] [Accepted: 10/02/2023] [Indexed: 11/21/2023]
Abstract
OBJECTIVE Effective treatment options are available for chronic venous insufficiency associated with superficial venous reflux. Although many patients with C2 and C3 disease based on the CEAP (Clinical-Etiological-Anatomical-Pathophysiological) classification have combined great saphenous vein (GSV) and saphenofemoral junction (SFJ) reflux, some may not have concomitant SFJ reflux. Several payors have determined that symptom severity in patients without SFJ reflux does not warrant treatment. In patients planned for venous ablation, we tested whether Venous Clinical Severity Scores (VCSS) are equivalent in those with GSV reflux alone compared with those with both GSV and SFJ reflux. METHODS This cross-sectional study was conducted at 10 centers. Inclusion criteria were: candidate for endovenous ablation as determined by treating physician; 18 to 80 years of age; GSV reflux with or without SFJ reflux on ultrasound; and C2 or C3 disease. Exclusion criteria were prior deep vein thrombosis; prior vein ablation on the index limb; ilio-caval obstruction; and renal, hepatic, or heart failure requiring prior hospitalization. An a priori sample size was calculated. We used multiple linear regression (adjusted for patient characteristics) to compare differences in VCSS scores of the two groups at baseline, and to test whether scores were equivalent using a priori equivalence boundaries of +1 and -1. In secondary analyses, we tested differences in VCSS scores in patients with C2 and C3 disease separately. RESULTS A total of 352 patients were enrolled; 64.2% (n = 226) had SFJ reflux, and 35.8% (n = 126) did not. The two groups did not differ by major clinical characteristics. The mean age of the cohort was 53.9 ± 14.3 years; women comprised 74.2%; White patients 85.8%; and body mass index was 27.8 ± 6.1 kg/m2. The VCSS scores in patients with and without SFJ reflux were found to be equivalent; SFJ reflux was not a significant predictor of VCSS score; and mean VCSS scores did not differ significantly (6.4 vs 6.6, respectively, P = .40). In secondary subset analyses, VCSS scores were equivalent between C2 patients with and without SFJ reflux, and VCSS scores of C3 patients with SFJ reflux were lower than those without SFJ reflux. CONCLUSIONS Symptom severity is equivalent in patients with GSV reflux with or without SFJ reflux. The absence of SFJ reflux alone should not determine the treatment paradigm in patients with symptomatic chronic venous insufficiency. Patients with GSV reflux who meet clinical criteria for treatment should have equivalent treatment regardless of whether or not they have SFJ reflux.

Abstract
Superficial venous thrombosis (SVT), an inflammatory-thrombotic process of a superficial vein, is a relatively common event that may have several different underlying causes. This phenomenon has been generally considered benign, and its prevalence has been historically underestimated; the estimated incidence ranges from about 0.3 to 1.5 event per 1000 person-years, while the prevalence is approximately 3 to 11%, with different reports depending on the population studied. However, such pathology is not free of complications; indeed, it could extend to the deep circulation and embolize to pulmonary circulation. For this reason, an ultrasound examination is recommended to evaluate the extension of SVT and to exclude the involvement of deep circulation. Also, SVT may be costly, especially in the case of recurrence. Therefore, accurate management is necessary to prevent sequelae and costs related to the disease. This review aims to analyse the epidemiology of SVT, its complications, optimal medical treatment, and open questions with future perspectives.

[PMID: 37952570 DOI: 10.1016/j.avsg.2023.09.088] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2022] [Revised: 07/18/2023] [Accepted: 09/18/2023] [Indexed: 11/14/2023]
Abstract
BACKGROUND Chronic venous insufficiency is a common medical condition that afflicts over 30 million adults in the United States. Treatment and management have changed dramatically over the past 20 years with the introduction of various endovenous therapies, including radiofrequency ablation (RFA) and cyanoacrylate closure using the Venaseal system. In this study, we explore a direct comparison of outcomes between RFA and VenaSeal conducted by a single surgeon within a managed care organization. METHODS Between May 2020 and December 2021, there were 87 patients undergoing 97 total procedures who were treated with either VenaSeal (n = 55) or RFA (n = 42), conducted by a single surgeon within a managed care organization. Primary outcomes included successful greater saphenous vein (GSV) closure, postoperative deep vein thrombosis (DVT), embolization, saphenofemoral junction (SFJ) thrombosis, skin reaction (allergic or thrombophlebitis), or procedure-related emergency room (ER) and urgent care (UC) visits. Retrospective chart review was conducted to describe patient demographics, indications for treatment, treatment details (number of access sites and indication for treatment), as well as follow-up adjunctive vein procedures (sclerotherapy and stab phlebectomy). RESULTS All patients had postprocedural ultrasound (US) performed within 7 days by the operating surgeon and mean overall patient follow-up from index procedure was 12 months; 2 patients were lost to follow-up due to death. All operations utilized intraoperative US, and SFJ thrombosis was not observed in any patient postprocedure. The average age of VenaSeal and RFA groups was 59.05 and 59.51 years, respectively. The average number of access sites during the procedure for VenaSeal and RFA was 1.56 and 1.20, respectively. Of the 55 VenaSeal treatments, 9.1% of patients reported postoperative skin reactions, and 9.1% of patients underwent subsequent stab phlebectomy (22 stabs on average). Of the 42 RFA treatments, 7.1% of RFA patients reported postoperative skin reactions, and 9.5% underwent subsequent stab phlebectomy (36 stabs on average). The percentage of patients who had postoperative UC or emergency department visits related to the procedure in the VenaSeal and RFA groups was 3.6% and 0%, respectively. CONCLUSIONS Both VenaSeal and RFA demonstrated effective vein closure of the GSV at 12-month follow-up, with VenaSeal demonstrating continued noninferiority to RFA. Based on our data, postoperative skin reactions do not appear to be significantly higher with VenaSeal treatment, as previously reported.

Abstract
This study describes trends in surgical versus endovascular interventions for treatment of chronic superficial venous disease (SVD) in the Medicare population. Medicare Part B data from 2010 to 2018 were obtained. Claims for SVD treatment were identified using Healthcare Common Procedure Coding System codes. Total percentage change in utilization rates and market share was determined for each provider group. Utilization of SVD treatments increased by 58%, mostly owing to growing utilization of endovascular treatments. There was a 66% decrease in surgical treatments. The utilization of ablation and sclerotherapy plateaued in 2016 and decreased in 2017-2018 with the advent of mechanochemical ablation, endovenous microfoam, and cyanoacrylate adhesive, respectively. Analysis showed that endovascular utilization increased across most specialties, with the largest growth seen in cardiology by 427%. Radiologists showed utilization growth of 125%, encompassing 11% of the market share. Endovascular treatment for SVD remains predominant, with increased utilization and concomitant decrease in surgical methods.

Abstract
Peripheral venous hypertension has emerged as a prominent characteristic of venous disease (VD). This disease causes lower limb edema due to impaired blood transport in the veins. The phlebotonic drugs in use showed moderate evidence for reducing edema slightly in the lower legs and little or no difference in the quality of life. To enhance the probability of favorable experimental results, a virtual screening procedure was employed to identify molecules with potential therapeutic activity in VD. Compounds obtained from multiple databases, namely AC Discovery, NuBBE, BIOFACQUIM, and InflamNat, were compared with reference compounds. The examination of structural similarity, targets, and signaling pathways in venous diseases allows for the identification of compounds with potential usefulness in VD. The computational tools employed were rcdk and chemminer from R-Studio and Cytoscape. An extended fingerprint analysis allowed us to obtain 1846 from 41,655 compounds compiled. Only 229 compounds showed pharmacological targets in the PubChem server, of which 84 molecules interacted with the VD network. Because of their descriptors and multi-target capacity, only 18 molecules of 84 were identified as potential candidates for experimental evaluation. We opted to evaluate the berberine compound because of its affordability, and extensive literature support. The experiment showed the proposed activity in an acute venous hypertension model.

Abstract
INTRODUCTION The prevalence of lower limb edema is high among patients with chronic venous disease (CVD). Several clinical studies with various designs have assessed the effect of micronized purified flavonoid fraction (MPFF) on edema. The aim of this work was to provide a comprehensive and accurate evaluation of the reduction in ankle and calf circumference as an indicator of lower limb edema reduction in patients with CVD treated with MPFF by combining studies that use different designs in a single group meta-analysis. EVIDENCE ACQUISITION We conducted a systematic literature review in April 2022 based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria to identify prospective studies investigating the effect of oral MPFF treatment 1000 mg/day on ankle and calf circumference in patients with CVD. Studies with population including at least one patient with an ulcer were excluded. All prospective studies irrespectively of design (i.e., interventional and non-interventional studies, randomized controlled trials (RCTs), non-randomized studies, studies without a control or reference treatment) were eligible. The Medline, Embase and Cochrane databases were searched. Endpoints were ankle and calf circumference measurements and their overall mean change from baseline estimated with random-effects meta-analysis methods. The evaluation criterion feeling of swelling was also analyzed as a standardized mean change (SMC) with 95% confidence intervals after combination of quantitative scales. EVIDENCE SYNTHESIS Among 861 articles identified, eight studies (five RCTs including one placebo-controlled, three non-comparative studies) met the criteria. The overall population consisted of 1635 patients, predominantly female (89% ranging from 64% to 94%) with a mean age of 47 years ranging from 41 to 48 years. Mean reduction in ankle circumference was 6.0 mm (95%CI: 3.6 to 8.4; P<0.001) and 7.0 mm (95%CI: 0.9 to 13.1; P=0.024) after two and at least six months of treatment respectively. The results were similar when considering the study type RCTs and non-RCTs. Mean reduction in calf circumference was 5.7 mm (95%CI: 2.8 to 8.6; P<0.001) and 6.7 mm (95%CI: 5.2 to 8.1; P<0.001), at two months and at the last post-baseline evaluation respectively. Heterogeneity among studies was statistically significant (degree of consistency I2=93.5%; P<0.001 and I2=81.1%, P<0.01 for ankle and calf circumference, respectively). In the three studies reporting the effect on feeling of swelling a significant standardized mean change (SMC) reduction of 2.2 (95%CI: 0.2 to 4.2; P=0.028) on a quantitative scale was observed after two months of treatment with MPFF. CONCLUSIONS MPFF appeared to be effective in reducing ankle and calf circumference as well as feeling of swelling irrespective of study design. The circumference reduction is present at short and long term, suggesting that benefit occurs early and is maintained overtime. Despite the observed heterogeneity among included studies, this meta-analysis supports the significant therapeutic efficacy of MPFF in reducing lower-limb edema in patients with CVD.

Abstract
INTRODUCTION VEIN STEP was conducted to collect international data on the management of chronic venous disease (CVD) and to assess the effectiveness of conservative treatments for the relief of CVD signs and symptoms. METHODS This international, observational, prospective, longitudinal, cohort study recruited adult outpatients consulting for symptomatic CVD. The primary objective was the effectiveness of conservative treatments on symptoms, signs and quality of life in a real-life setting assessed using a range of patient-reported outcome measures: 10-cm Visual Analog and Patient Global Impression of Change scales for symptoms; Venous Clinical Severity Score for physician assessment of signs; and 14-item ChronIc Venous Insufficiency Questionnaire (CIVIQ-14) for quality of life. At inclusion, patients were prescribed conservative treatment according to the physicians' usual practice. Follow-up visits took place at weeks 2 and 4, with an optional week 8 visit. RESULTS The analysis set comprised 6084 subjects (78% female) from nine countries with a mean age of 50.6 ± 13.8 years and BMI of 28.0 ± 4.9 kg/m2. The most common CEAP classifications were C1 (23.0%), C2 (31.6%), and C3 (30.7%). Conservative therapy consisted of oral venoactive drugs (VADs; 95.8% of subjects) including micronized purified flavonoid fraction (MPFF 75.5%) and diosmin (18.8%), compression (52.0%), and topicals (31.5%). Conservative therapy led to global symptom improvement in 89% of patients after 2 weeks and 96% at 4 weeks. Pain, leg heaviness, cramps, and sensation of swelling were improved in 82%, 71%, 45.5%, and 46% of patients, respectively. Conservative therapy was associated with a decrease over time in patient-assessed global symptom intensity: - 2.37 ± 1.73 (P < 0.001) and physician-assessed disease severity - 1.83 ± 2.82 (P < 0.001). Among the VADs, MPFF-based conservative therapy was associated with the greatest reduction in symptom and sign intensity. Improvements in CIVIQ-14 were observed with all treatments but were greatest for MPFF. CONCLUSION In this prospective study conducted in the real-world setting, treatment with conservative therapy, in particular MPFF, was associated with meaningful improvements in the clinical signs and symptoms of disease as well as in quality of life in patients with CVD.

Abstract
INTRODUCTION The progression of chronic venous disease (CVD) is characterized by edema of the legs and/or venous ulcers of the lower limbs in association with cutaneous signs and/or skin alterations, such as hyperpigmentation, corona phlebectatica, telangiectasia, eczematous dermatitis, lipodermatosclerosis, atrophie blanche, cellulitis, and induration. Xioglican cream is a galactosaminoglycan polysulfate and hyaluronic acid-containing medical device with strong hydrophilic, moisturizing, and soothing properties. This post-marketing observational study evaluated topical Xioglican cream in the amelioration of skin manifestations and clinical signs and symptoms in patients with CVD treated in routine clinical practice. METHODS Adult patients (18-75 years) with a clinical diagnosis of C2-C3 CVD according to Clinical, Etiology, Anatomy, and Pathophysiology (CEAP) classification who received 12 weeks of treatment with Xioglican (applied up to 3 times daily), according to investigator decision (and consistent with conventional clinical practice and established standard of care), were enrolled from two study sites in Italy. A range of endpoints were used to evaluate efficacy, safety, effect on patient quality of life (QoL), and patient satisfaction with topical application of Xioglican cream in the physiological restoration of skin signs and symptoms. RESULTS In patients with CVD (n = 30), Xioglican cream reduced CVD-related skin manifestations and associated symptoms, with significant reductions in leg circumference [mean ± standard deviation (SD): - 3.21 ± 3.39 cm for left and - 2.92 ± 2.70 cm for right legs, both p < 0.0001] and local edema (- 5.52 ± 7.94 cm, p = 0.0034) and significant improvement in Venous Clinical Severity Scores (mean 0.52 ± 1.94 decrease from baseline, p = 0.1952) observed after 12 weeks. Skin burning, pain, aching or tiredness, and QoL were also significantly improved. There was no change in CEAP classification. Globally, 92.0% of patients were "Very satisfied" or "Satisfied" with the product. CONCLUSIONS Topical treatment with Xioglican cream improves the signs, symptoms, and QoL of patients with CVD class C2-C3.

Abstract
OBJECTIVE The benefit of using electric stimulation therapy (EST) to heal venous leg ulcers (VLUs) is not well established. The main aim of this systematic review was to evaluate the effects of ulcer EST in VLU healing. METHODS A systematic search of the literature was conducted using the databases PubMed, Scopus, and Web of Science and included original studies that reported VLU healing after EST. The inclusion criteria were at least two surface electrodes placed on or near the wound or a planar probe covering the ulcer area to be treated. The Cochrane risk of bias tool for randomized control trials (RCTs) and Joanna Briggs Institute critical appraisal checklist for case series were used to evaluate the risk of bias. RESULTS This review included eight RCTs and three case series involving a total of 724 limbs in 716 patients with VLUs. The mean patient age was 64.2 years (95% confidence interval, 62.3-66.2), and 46.2% (95% confidence interval, 41.2%-50.4%) were men. The active electrode was placed on the wound with the passive electrode placed on healthy skin (n = 6), the two electrodes were placed on either side of the wound edges (n = 4), or a planar probe was used (n = 1). The pulsed current was the most used waveform (n = 9). The change in the ulcer size was the main method used to determine ulcer healing (n = 8), followed by the ulcer healing rate (n = 6), exudate levels (n = 4), and the time to healing (n = 3). Five RCTs detected a statistically significant improvement in at least one VLU healing outcome, after EST compared with the control group. In two of these, EST was better than the control but only for patients who had not undergone surgical treatment of VLU. CONCLUSIONS The findings from the present systematic review support the use of EST to accelerate wound healing of VLUs, especially for patients who are not surgical candidates. However, the significant variation in electric stimulation protocols represents an important limitation to its use and should be addressed in future studies.

Abstract
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.

Abstract
Background: Compression therapy is the gold standard for the treatment of chronic venous insufficiency (CVI). Two-layer bandage (2LB) systems have been shown to be a safe and effective treatment option. Objective: To estimate the total cost per response (CPR) for the resolution of edema and wounds in patients with CVI treated with a 2LB system as part of their overall wound healing regimen. Methods: A probabilistic decision tree model was developed to estimate the incremental CPR for a 2LB system. The model simulated 10 000 patients to estimate the CPR for the resolution of edema and wound healing. The analysis was performed using clinical data from a published single-arm, multicenter prospective study of CVI indicated for compression therapy. The response outcomes of interest were resolution of edema and rate of wound healing. The follow-up time was a maximum of 6 weeks, and the perspective of the study was a US outpatient treatment center. Economic data for compression therapy were based on the public prices of a 2LB system. Dressing changes occurred per manufacturer instructions for use. Results: The study comprised 702 patients (56% female), with a total of 414 wounds. The median duration of the wounds was 42 days, and the median size at the initial visit was 3.5 cm2. The average pain reduction fell by 67% using a visual analog score. Bandages were typically changed once or twice a week (51.7%). Wound healing occurred in 128 of the 414 wounds (30.9%). The expected incremental CPR of a 2LB system for the resolution of edema was $65.67 (range, $16.67-$124.32). The expected incremental CPR of a 2LB system for the healing of a wound was $138.71 (range, $35.71-$273.53). Conclusion: This economic evaluation complements previous clinical effectiveness and safety studies of 2LB systems for the treatment of CVI. The results demonstrate that the costs of incorporating 2LB into standard wound-healing protocols are negligible compared with overall treatment costs. Two-layer bandages may be considered a cost-effective first-line system for the treatment of wounds caused by CVI.

[PMID: 37086915 DOI: 10.1016/j.jvsv.2023.03.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 02/15/2023] [Accepted: 03/11/2023] [Indexed: 04/24/2023]
Abstract
Venous disease is prevalent, undertreated, and frequently unrecognized. During the past two decades, new treatment modalities have changed how venous disease is approached. Some of these treatment modalities are only available in certain centers or locations and access to care could be inequitable. Although venous disease affects millions in the United States, we have little understanding of the gender, socioeconomic, and ethnic disparities in both superficial and deep venous disease presentation. In an effort to better understand the treatment of male and female patients from different gender, ethnic, and socioeconomic backgrounds, literature searches were conducted to investigate how these patients were evaluated and treated. PubMed was used to search literature using the terms "venous insufficiency," "superficial venous disease," "venous thromboembolism," "deep vein thrombosis," "DVT," "May-Thurner," and "pulmonary embolism," with gender, sex, racial, and socioeconomic disparities and differences within the keywords. In addition, once articles were discovered, the "similar articles" function was used to expand the search. The included studies were restricted to those reported from 1995 to the present. Given the paucity of data, no study was excluded. It is readily apparent that there is not enough data to make decisions that would modify treatment to affect the outcomes of patients with differing backgrounds and gender. Studies currently are limited to evaluating patients by sex assigned at birth without interrogation of their identified gender. It is imperative that consideration is given to evaluating gender and ethnic differences, because treatment options might need to be tailored accordingly. Outreach and education for underserved patient populations with improvement in access to care must also be incorporated into the healthcare system. Additional work in this area is required. Further data collection and research related to demographic disparities among patients with venous disease is necessary to better understand the differences that could change treatment algorithms tailored to specific groups.

Sanches‐Pinto DC, Eriksson E, Gomez DS, Nunes MPT, Gemperli R, Soriano FG. Minced skin grafts for chronic wounds compared to conventional mesh grafts. Health Sci Rep 2023; 6:e1353. [PMID: 37359407 PMCID: PMC10285033 DOI: 10.1002/hsr2.1353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 06/02/2023] [Accepted: 06/05/2023] [Indexed: 06/28/2023] Open
Abstract
Background and Aims Skin grafting is the single most effective method to close a chronic wound. The current standard of care is to use meshed split thickness skin grafts. This entails the use of surgical instruments that need to be autoclaved and to have a power source, which usually requires an OR facility. The minced skin technique uses single use, presterilized instruments and the procedure can be done under local anesthesia, by a wound care practitioner, in a wound clinic, a physician's office or even at the bedside. The current study was designed to determine if the results from micrografting were non inferior to conventional mesh grafting. Methods In a prospective non inferiority study, 26 chronic ulcers were treated with micrografting (MSG) and 24 with conventional mesh grafts 1:3 (control group-CG) in a total of 21 patients, 10 male and 11 female. The donor site areas in the MSG group were predetermined to 2.5 × 5 cm and the mesh grafts expansion was set at 1:3. Results In the first weeks postoperatively, micrograft healing initially lagged behind the conventional mesh grafts but at 60 days after grafting, all MSG wounds were healed. The MSG wounds had better pigmentation, less itching, and less scarring. The micrografting procedure was easy to learn and expeditious to perform. The MSG mean expansion was 9.1 compared to three times (CG). Conclusion The MSG procedure is not inferior to conventional mesh grafting, requires smaller donor sites, and can be done with single use instruments, under local anesthesia, with early discharge.

Abstract
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.

Abstract
BACKGROUND The efficacy and tolerability of the new micronized purified flavonoid fraction (MPFF) 1000 mg once-daily chewable formulation in comparison with the established MPFF 500 mg conventional tablet at the same daily dose are unknown. METHODS CHEWY was an international, multicenter, double-blind, double-dummy, randomized, parallel group, non-inferiority phase III study conducted in adult patients with symptomatic chronic venous disease (CVD). Patients were randomly allocated to MPFF 1000 mg chewable or MPFF 2x500 mg daily treatment. The primary efficacy endpoint for clinical non-inferiority (non-inferiority margin predefined at 1 cm) was lower limb discomfort (LLD) assessed by a 10 cm electronic visual analog scale (eVAS) at 8 weeks. Secondary endpoints included leg pain (LP), leg heaviness (LH), and quality of life (QoL) measured by the eCIVIQ-14 questionnaire. Overall acceptability was assessed at each visit by patient and investigator. RESULTS Three hundred and nine patients were randomized to MPFF 1000 mg chewable and 302 to MPFF 2x500 mg. After 8 weeks, LLD decreased from baseline by -3.6±2.4 cm and -3.6±2.5 cm in the MPFF chewable and 2x500 mg groups, respectively. Non-inferiority of the once-daily chewable formulation compared with twice daily tablets on improving LLD was demonstrated (adjusted between-group difference [Standard Error]) (E [SE]) = 0.00 (0.18) cm, 95%CI -0.35; 0.35, non-inferiority P value <0.0001. Decreases of similar magnitude were observed at 8 weeks for LP and LH in both treatment arms: -3.4±2.3 cm and -3.5±2.5 cm, respectively for LP, and -3.5±2.5 cm and -3.5±2.6 cm, respectively for LH. QoL (global score) improved by -21.0±17.2 and -22.5±20.1 in the MPFF 1000 mg chewable group and 2x500 mg groups, respectively (E [SE]=1.03 [1.20], 95%CI [-1.32; 3.38]), with similar improvements in the QoL subscore components in both groups. Treatment acceptability was high for both patients and physicians and tolerability similar to the tablet formulation. CONCLUSIONS MPFF 1000 mg chewable was non-inferior to MPFF 2x500 mg tablets with respect to its effect on LLD. Both formulations were associated with improvements of similar magnitude in lower limb symptoms and QoL. The chewable formulation was observed to be well tolerated and well accepted. Once-daily MPFF chewable tablet offers patients with CVD a good alternative treatment regimen.

Abstract
OBJECTIVES The aim of this study was to evaluate the epidemiology of varicose vein stripping in Brazil's largest city, São Paulo. METHODS Open and anonymous data regarding varicose vein surgeries between 2008 and 2018 were evaluated from the TabNet platform of the Municipal Health Secretary of São Paulo, Brazil. RESULTS Most patients were female and adults. A total of 66,577 varicose vein surgeries were performed in public hospitals and outpatient clinics in São Paulo, with a statistically significant increase for both unilateral (p=0.003) and bilateral (p<0.001) procedures. Since 2016, unilateral procedures have been performed more frequently than bilateral procedures. Most procedures were associated with same-day (54.8%) or next-day (32%) discharge. The in-hospital mortality rate was 0.0045%. The total amount reimbursed was $20,693,437.94, corresponding to a mean value of $310.82 per procedure. CONCLUSION Surgeries to treat chronic vein disease totaled 66,577 in 11 years, demanding $20,693,437.94 from the public health system. The majority of treated patients were female, over 40 years of age, and local residents. Procedure rates have increased over the years. The in-hospital mortality rate was very low (0.0045%).

Venous Wall of Patients with Chronic Venous Disease Exhibits a Glycolytic Phenotype. J Pers Med 2022; 12:jpm12101642.

Abstract
Chronic venous disease (CVeD) is a rising medical condition characterized by a broad spectrum of disorders in the venous system. Varicose veins (VVs) represent a frequent clinical manifestation of CVeD, particularly in the lower limbs. Prior histopathological studies have defined a set of alterations observed in the venous wall of patients with VVs, affecting their structure and behavior. Metabolic changes in the veins appear to be a critical biological mechanism aiding our understanding of the pathogenesis of CVeD. In this sense, previous studies have identified a potential role of a glycolytic phenotype in the development of different vascular disorders; however, its precise role in CVeD remains to be fully explored. Thus, the aim of the present study was to analyze the gene and protein expression of glucose transporter 1 (GLUT-1) and the glycolytic enzymes PGK-1, ALD, GA3PDH and LDH in the VVs of patients with CVeD (n = 35) in comparison to those expressed in healthy subjects. Our results display enhanced gene and protein expression of GLUT-1, PGK-1, ALD, GA3PDH and LDH in patients with CVeD, suggesting a glycolytic switch of the venous tissue. Greater understanding of the impact of this glycolytic switch in patients with CVeD is required to define a possible pathophysiological role or therapeutic implications of these changes.

Abstract
BACKGROUND Pregnancy is a known risk factor for developing varicose veins (VV). However, pregnancy is often considered a homogeneous entity and few studies have examined if specific characteristics and complications of pregnancy may influence VV formation. This study sought to identify which pregnancy-specific factors are associated with the development of VV. METHODS All women who gave birth (live or still) between 1998-2020 within a multicenter healthcare system were retrospectively identified and followed through all hospital encounters (inpatient and outpatient). The primary outcome was VV, defined as any encounter with a primary diagnosis code for VV or procedure for VV. The study period for each woman was the time from the first to last encounter. Extended Cox regression modeling evaluated the association between VV and pregnancy-related factors as a time-varying covariates while controlling for patient comorbidities. RESULTS There were 156,622 women with a median follow-up of 8.3 years (IQR: 2.7-16.6 years) included. During this time, 225,758 deliveries occurred. The 10- and 20-year freedom from VV was 97.0% (95%CI: 96.8-97.1%) and 92.7% (95%CI: 92.4-93.0%), respectively, from the estimated start of first pregnancy. Overall, 4,028 (2.57%) developed VV during the follow-up period and 1,594 (1.02%) underwent a procedure for VV. After risk adjustment, increasing parity was significantly associated with VV, with each subsequent pregnancy increasing hazard of developing VV (parity=1: HR 1.78; 95%CI: 1.55-1.99; p<0.001; parity≥6: HR 4.83; 95%CI: 2.15-1.99-10.9; p<0.001), Other significant pregnancy factors included excessive weight gain in pregnancy (HR 1.44; 95%CI: 1.09-1.91; p=0.011), post-term pregnancy (HR 1.12; 95%CI: 1.02-1.21; p=0.021), preeclampsia (HR 0.79; 95%CI: 0.70-0.90; p<0.001), and postpartum transfusion of platelets, plasma, or cryoprecipitate (HR 2.05; 95%CI: 1.19-3.53; p=0.001). CONCLUSION Increasing parity, excessive weight gain in pregnancy, post-term pregnancy, and preeclampsia affect the development of VV after pregnancy. Though varicose veins after pregnancy are likely underreported and true incidence is unknown, women should be counseled about the impact of these factors on VV development after pregnancy.

Abstract
The importance of chronic venous disease (CVD), as a cause of reduced quality of life and increased costs to healthcare systems, is expected to rise in parallel with population aging and the increasing prevalence of obesity. Venoactive drugs (VADs) are frequently used to treat the symptoms and signs of CVD. The most commonly used and widely studied VAD, micronised purified flavonoid fraction (MPFF), is effective at all stages of CVD, and has been shown to significantly reduce leg pain, leg heaviness and swelling, as well as ankle oedema and functional discomfort, in clinical trials. Recently, experiments employing animal models of CVD have demonstrated that MPFF has anti-inflammatory and venotonic effects at the microvalve level, and a pilot clinical study in patients with CVD has provided support for these findings. Collectively, these results suggest that early initiation of MPFF treatment may have the potential to favourably alter the clinical course of the disease, although further clinical data are required to confirm these findings. International guidelines on CVD management strongly recommend MPFF to reduce symptoms and improve quality of life. Studies are now needed to investigate the impact of long-term treatment on disease progression.

Abstract
BACKGROUND varicose vein surgeries are the most commonly performed vascular procedure to treat the most prevalent vascular disease, chronic venous disease. However, nationwide studies on the epidemiology of varicose vein surgeries are scarce, none in developing countries. Therefore, we designed this study to assess the total number of varicose vein surgeries performed between 2008 and 2019 in the Public Health System, which exclusively insures more than 160 million Brazilians, their trends, costs and mortality rates. METHODS public and open data referring to all surgeries to treat chronic venous disease between 2008 and 2019 were extracted from the Brazilian Ministry of Health database. RESULTS 869,220 surgeries were performed to treat chronic venous disease in Brazilian public hospitals and outpatient clinics, with an average rate of 4.5 surgeries per 10,000 inhabitants per year. Starting in 2015, we observed a slight non-significant downward trend in the total number of procedures. The total amount reimbursed by the government was US$ 232,775,518.11. A total of 49 deaths were reported after varicose vein surgery, corresponding to a mortality rate of 0.0056%. CONCLUSIONS 869,220 surgeries were performed to treat chronic venous disease over twelve years, with an overall rate of 4.52 procedures per 10,000 population per year. The mortality rate was very low, 0.0056%.

Abstract
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.
