Abstract
BACKGROUND Post-thrombotic syndrome (PTS) is the main long-term complication of deep vein thrombosis (DVT). Several therapies are being evaluated to prevent or to treat PTS. Identifying the patients most likely to benefit from these therapies presents a significant challenge. OBJECTIVES The objective of this review was to identify risk factors for PTS during the acute phase of DVT. ELIGIBILITY CRITERIA We searched the PubMed and Cochrane databases for studies published between January 2000 and January 2021, including randomized clinical trials, meta-analyses, systematic reviews and observational studies. RESULTS Risk factors for PTS such as proximal location of DVT, obesity, chronic venous disease, history of DVT are associated with higher risk of PTS. On the initial ultrasound-Doppler, a high thrombotic burden appears to be a predictor of PTS. Among the evaluated biomarkers, some inflammatory markers such as ICAM-1, MMP-1 and MMP-8 appear to be associated with a higher risk of developing PTS. Coagulation disorders are not associated with risk of developing PTS. Role of endothelial biomarkers in predicting PTS has been poorly explored. Lastly, vitamin K antagonist was associated with a higher risk of developing PTS when compared to direct oral anticoagulants and low molecular weight heparin. CONCLUSIONS Several risk factors during the acute phase of VTE are associated with an increased risk of developing PTS. There is a high-unmet medical need to identify potential biomarkers for early detection of patients at risk of developing PTS after VTE. Inflammatory and endothelial biomarkers should be explored in larger prospective studies to identify populations that could benefit from new therapies.

Abstract
BACKGROUND Chronic venous insufficiency (CVI) often leads to venous ulcers. The relationship between ankle joint range of motion (ROM) and venous ulcers remains under-investigated. This study aims to clarify this relationship using ultrasound imaging. METHODS We conducted a study on 20 patients with unilateral venous ulcers. Ankle ROM and popliteal vein blood flow were measured using a goniometer and ultrasound, respectively. The measurements were compared between the affected and unaffected limbs. RESULTS A significant reduction in ROM and popliteal vein blood flow was observed in the limbs with venous ulcers compared to the unaffected limbs. The data suggest a correlation between reduced ankle mobility and the development of venous ulcers. CONCLUSION The study underscores the importance of maintaining ankle mobility in patients with CVI to prevent venous ulcers. A multifactorial approach is essential for managing these conditions effectively.

Abstract
OBJECTIVE Chronic venous disease is a common condition and has a significant impact on patients' health status. Validated patient-reported outcome measures (PROMs) used to assess health status are needed to measure health status. This state-of-the-art review summarizes the current validation evidence for disease-specific PROMs for chronic venous disease and provides a framework for their use in the clinical setting. METHODS A literature search in OVID Embase and Medline was conducted to identify relevant English-language studies of chronic venous disease that used disease-specific PROMs between January 1, 1993, and June 30, 2022. Abstracts and titles from identified studies were screened by four investigators, and full-text articles were subsequently screened for eligibility. Data on validation of disease-specific PROMs was abstracted from each included article. Classical test theory was used as a framework to examine a priori defined validation criteria for content validity, reliability (construct validity, internal reliability, and test-retest reliability), responsiveness, and expansion of the validation evidence base (use in randomized controlled trials and comparative effectiveness research, cultural or linguistic translations, predictive validity, or establishing the minimal clinically important difference threshold, defined as smallest amount an outcome or measure is perceived as a meaningful change to patients). The PROMs were categorized into three groups based on the manifestations of disease of the population for which they were developed. The overall validity of each PROM was assessed across three stages of validation including content validity (phase 1); construct validity, reliability, and responsiveness (phase 2); and expansion of the validation evidence base (phase 3). RESULTS Of 2338 unique studies screened, 112 studies (4.8%) met inclusion criteria. The eight disease-specific PROMs identified were categorized into three groups: (1) overall chronic venous disease (C1 to C6); (2) C1 to C4 disease; and (3) C5 to C6 disease. Assessed by group, the Chronic Venous Insufficiency Questionnaire met criteria for validation at all three phases for patients with C1 to C4 disease, and the Charing Cross Venous Ulcer Questionnaire met criteria for validation at all three phases for patients with C5 to C6 disease. There were no PROMs that met all criteria for validation for use in overall chronic venous disease (C1 to C6). CONCLUSIONS Of the eight PROMs assessed in this review, only two met prespecified criteria at each phase for validation. The Chronic Venous Insufficiency Questionnaire and Charing Cross Venous Ulcer Questionnaire should be considered for use in patients with chronic venous disease without venous ulcers and with venous ulcers, respectively.

Abstract
BACKGROUND Microfoam ablation (MFA) and radiofrequency ablation (RFA) are both approved by the Food and Drug Administration for treatment of proximal saphenous truncal veins. The objective of our study was to compare early postoperative outcomes between MFA and RFA following treatment of incompetent thigh saphenous veins. METHODS A retrospective review of a prospectively maintained database was conducted of patients who underwent treatment of incompetent great saphenous veins (GSVs) or anterior accessory saphenous veins (AASVs) in the thigh. All the patients underwent duplex ultrasound of the treated leg at 48 to 72 hours postoperatively. Patients were excluded from analysis if concomitant stab phlebectomy was performed. Demographic data, CEAP (clinical, etiologic, anatomic, pathophysiologic) class, venous clinical severity score (VCSS), and adverse events were recorded. RESULTS Between June 2018 and September 2022, 784 consecutive limbs (RFA, n = 560; MFA, n = 224) underwent venous closure for symptomatic reflux. A total of 200 consecutive thigh GSVs and ASVs treated within the study period using either MFA (n = 100) or RFA (n = 100) were identified. The patients were predominantly women (69%) with a mean age of 64 years. The preoperative CEAP classification was similar between the MFA and RFA groups. The mean preoperative VCSS was 9.4 ± 2.6 for the RFA patients and 9.9 ± 3.3 for the MFA patients. Among the RFA patients, the GSV was treated in 98% and the AASV in 2% compared with the GSV in 83% and the AASV in 17% in the MFA group (P < .001). The mean operative time was 42.4 ± 15.4 minutes in the RFA group and 33.8 ±16.9 minutes in the MFA group (P < .001). The median follow-up was 64 days for the study cohort. The mean postoperative VCSS declined to 7.3 ± 2.1 in the RFA group and 7.8 ± 2.9 in the MFA group. Complete closure occurred in 100% of the limbs after RFA and 90% after MFA (P = .005). Eight veins were partially closed and two remained patent following MFA. The incidence of superficial phlebitis was 6% and 15% (P = .06) after RFA and MFA, respectively. Overall, symptomatic relief was 90% following RFA and 89.5% following MFA. The complete ulcer healing rate for the entire cohort was 77.8%. Deep venous proximal thrombus extension (RFA, 1%; vs MFA, 4%; P = .37) and remote deep vein thrombosis (RFA, 0%; vs MFA, 2%; P = .5) showed a trend toward being higher following MFA but the difference did not reach statistical significance. All were asymptomatic and resolved with short-term anticoagulation therapy. CONCLUSIONS MFA and RFA are both safe and effective for treating incompetent thigh saphenous veins, with excellent symptomatic relief and a low incidence of postprocedure adverse thrombotic events. RFA resulted in improved complete closure rates following initial treatment compared with MFA. The operative times were shorter with MFA. Both modalities can be used for patients with active venous ulcers with good healing rates. Longer term studies are required to characterize the durability of MFA closure for above knee truncal veins.

Abstract
BACKGROUND Up to one half of patients with a diagnosis of deep vein thrombosis will develop post-thrombotic syndrome (PTS). Patients with PTS can develop venous leg ulcers (VLUs) due to post-thrombotic obstructions (PTOs) that contribute to prolonged ambulatory venous hypertension. The current treatments for PTS, which include chronic thrombus, synechiae, trabeculations, and inflow lesions, do not target PTOs, and such obstructions can affect stenting success. The aim of the present study was to determine whether removal of chronic PTOs using percutaneous mechanical thrombectomy would promote VLU resolution and positive outcomes. METHODS In this retrospective analysis, the characteristics and outcomes for patients with VLUs secondary to chronic PTO who were treated using the ClotTriever System (Inari Medical) between August 2021 and May 2022 were assessed. Technical success was considered the ability to cross a lesion and introduce the thrombectomy device. Clinical success was defined as a decrease of ≥1 in the severity category for the ulcer diameter using the revised venous clinical severity score (score 0, no VLU; score 1, mild VLU [size <2 cm]; score 2, moderate VLU [size 2-6 cm]; score 3, severe VLU [size >6 cm]) at the latest follow-up visit. RESULTS A total of 11 patients with 15 VLUs on 14 limbs were identified. Their mean age was 59.7 ± 11.8 years, and four patients (36.4%) were women. The median VLU duration was 11.0 months (interquartile range [IQR], 6.0-17.0 months), and 2 patients had VLUs secondary to a deep vein thrombosis event >40 years previously. All treatments were performed in a single session, with technical success achieved in 100% of the 14 limbs. A median of five passes (IQR, four to six passes) with the ClotTriever catheter were performed per limb. Chronic PTOs were successfully extirpated, and intraprocedural intravascular ultrasound showed effective disruption of venous synechiae and trabeculations. Stents were placed in 10 limbs (71.4%). The time to VLU resolution or the latest follow-up was 12.8 ± 10.5 weeks, and clinical success was achieved for all 15 VLUs (100%), with the revised venous clinical severity score for the ulcer diameter improving from a median of 2 (IQR, 2-2) at baseline to a median score of 0 (IQR, 0-0) at last follow-up. The VLU area had decreased by 96.6% ± 8.7%. Of the 15 VLUs, 12 (80.0%) had resolved completely, and 3 had demonstrated near-complete healing. CONCLUSIONS All patients showed complete or near-complete VLU healing within a few months after mechanical thrombectomy. Mechanical extirpation and interruption of chronic PTOs allowed for luminal gain and restoration of cephalad inflow. With additional investigation, mechanical thrombectomy with the study device could prove a vital component to the treatment of VLUs secondary to PTOs.

Abstract
There are 5 common types of chronic nonhealing lower-extremity wounds: arterial, venous, diabetic foot ulcer, pressure, and mixed or atypical. Each chronic wound type has distinct features, and understanding the underlying cause will dictate the wound treatment plan. Here, the authors review the distinguishing wound properties for these 5 common chronic nonhealing lower-extremity wounds and outline a comprehensive treatment plan that addresses wound perfusion, debridement, infection control, moisture balance, and use of complementary advanced wound care products.

Abstract
OBJECTIVE In the present study, we summarize our experience in locating the nidus of arteriovenous malformations (AVMs) with a dominant outflow vein (DOV) in the lower extremities and eradicating the nidus with ethanol and coils. METHODS Twelve patients with lower extremity AVMs who underwent ethanol embolization combined with DOV occlusion from January 2017 to May 2018 were enrolled in the present study. Selective angiography was used to locate the nidus of the AVMs, which was eradicated using ethanol and coils via the direct puncture pathway. All treated patients underwent postoperative follow-up (mean, 25.5 months; range, 14-37 months). RESULTS The 12 patients underwent a total of 29 procedures (mean, 2.4; range, 1-4) with 27 detachable coils and 169 Nester coils (Cook Medical Inc, Bloomington, IN). Of the 12 patients, 7 (58.3%) had a complete response and 5 (41.7%) a partial response. Three patients (25%) had minor complications such as blister and superficial skin ulcers during follow-up. However, they recovered spontaneously and completely. No major complications were recorded. CONCLUSIONS Ethanol embolization combined with coil-assisted DOV occlusion has the potential to eradicate the nidus of lower extremity AVMs with acceptable complication rates.

Abstract
INTRODUCTION Traumatic arteriovenous fistula (TAVF) may be challenging to diagnose and can be misjudged as skin lesions or ulcers, including cutaneous leishmaniasis. Here, we present a patient with TAVF misdiagnosed and treated as cutaneous leishmaniasis. CASE PRESENTATION A 36-year-old male presented with a non-healing venous ulcer in his left leg, which was misdiagnosed and treated as cutaneous leishmaniasis. He was referred to our clinic, where color Doppler sonography showed arterial flow in the left great saphenous vein, and Computed tomographic (CT) angiography revealed left superficial femoral artery fistula to the femoral vein. The patient had a history of shotgun injury six years ago. Surgical closure of the fistula was done. The ulcer healed completely one month after the surgery. DISCUSSION AND CONCLUSION TAVF may present as skin lesions or ulcers. Our report emphasizes the importance of thorough physical examination and history taking and the use of color Doppler sonography in order to avoid unnecessary diagnostic and therapeutic modalities.

Abstract
BACKGROUND Venous ulcers usually present a torpid evolution with a negative impact on patients' quality of life. In primary care, they account for 2.5% of nursing consultations and their treatment represents high costs for national health systems. These patients usually have a low level of physical activity, with muscle pump dysfunction of the lower limbs, which may improve with increased physical activity. The purpose of this study is to analyse the effectiveness of a structured intervention involving physical activity and exercise (Active Legs) as an adjuvant treatment in improving healing of chronic venous ulcers at 3 months follow-up. METHODS A randomized, multicentre clinical trial. A total of 224 individuals receiving primary nursing care with a diagnosis of venous ulcer, with a diameter of 1 cm or greater and an ankle-brachial index between 0.8 and 1.3, able to comply with the study requirements and consenting to participate, will be sequentially included (112 per group). Both groups will receive the standard treatment in primary care, with cleansing, debridement and healing in a moist environment together with multilayer compression therapy. The intervention group will also receive a structured educational intervention involving lower limb physical exercise and daily ambulation guidelines. The primary response variables will be complete healing -understood as complete and sustained epithelialisation for at least 2 weeks- and time to healing. The secondary variables will be degree of healing, ulcer area, quality of life, pain and variables related to the healing process, prognosis, and recurrences. Sociodemographic variables, adherence to treatment and satisfaction variables will also be recorded. Data will be collected at baseline, at 3 months and at 6 months follow-up. Survival analysis (Kaplan-Meier and Cox) will be performed to measure primary effectiveness. Intention-to-treat analysis. DISCUSSION If the intervention is effective, a cost-effectiveness analysis could be conducted and implemented as an additional intervention in the usual venous ulcer treatment in primary care.

Abstract
OBJECTIVE This retrospective trial analyzed the effect of predetermined variables on venous ulcer healing after endovenous ablation of insufficient veins. METHODS A total of 259 patients presenting 273 venous leg ulcers (VLUs) at Oulu University Hospital vascular outpatient clinic between January 2010 and December 2020 were included in the study. In addition to compression therapy, all patients received endovenous ablation (endothermal ablation and/or foam sclerotherapy) to promote venous healing. The hazard ratio (HR) for an ulcer to heal was analyzed in univariate analysis of predetermined factors, including age, sex, recurrent venous ulcer, presence of great saphenous vein or small saphenous vein reflux, persistent superficial vein reflux after ablation, recanalization in treated segments, ulcer age, body mass index >35 kg/m2, history of deep vein thrombosis, history of erysipelas, ability to move, smoking, hypertension, atrial fibrillation, coronary artery disease, diabetes mellitus, and cardiac insufficiency. Logistic regression was used in a multivariate analysis to identify independent risk factors for ulcer healing. RESULTS In the univariate analysis, healing was negatively associated with persistent superficial vein reflux after ablation (HR, 0.117; 95% confidence interval [CI], 0.088-0.354), recanalization in treated segments (HR, 0.161; 95% CI, 0.060-0.433), nonambulatory patient (HR, 0.322; 95% CI, 0.130-0.800), history of deep vein thrombosis (HR, 0.518; 95% CI, 0.294-0.910), and presence of small saphenous vein reflux (HR, 0.565; 95% CI, 0.384-0.830). Independent risk factors included persistent superficial vein reflux after ablation (HR, 0.123; 95% CI, 0.0051-0.295). All the patients in the persistent superficial vein reflux group had their VLUs eventually healed after further endovenous treatment. CONCLUSIONS When treating patients with VLUs, persistent superficial vein reflux after ablation was negatively associated with ulcer healing. After additional endovenous ablative treatment, ulcers with persistent reflux eventually healed.

Abstract
OBJECTIVE An active venous leg ulcer (VLU) caused by lower extremity venous insufficiency is challenging to treat and will often recur after initially healing. In the present study, we compared the symptomatic outcomes and need for reoperation after iliac vein stenting (IVS) in patients with an active VLU (VLU+) and those without an active VLU (VLU-). METHODS A single-institution database of patients with chronic venous outflow obstruction who underwent IVS from August 2011 to June 2021 was analyzed. Symptoms were quantified using the venous clinical severity score. The patients were divided into two cohorts: those with (VLU+) and without (VLU-) VLUs. RESULTS A total of 872 patients (71 VLU+ and 801 VLU-) were identified. Many of the demographics and comorbidities differed between the two cohorts, and these variables were included in the multivariable analysis. On univariate analysis, the VLU+ cohort was more likely to need a major reoperation (odds ratio, 1.94; 95% confidence interval, 1.01-3.52; P = .036). However, on multivariable analysis, the difference was not statistically significant (odds ratio, 1.17; 95% confidence interval, 0.55-2.40; P = .667). Additionally, the VLU+ cohort required a significantly greater mean total of reoperations (1.4 vs 1.0; P = .006) than the VLU- cohort. Comparatively, for patients who underwent at least one reoperation, the difference in the mean total number of reoperations was even greater for the VLU+ cohort (2.6 vs 1.8; P = .001). The results from the Kaplan-Meier log-rank test revealed no differences in the reintervention-free survival time (P = .980). Both cohorts experienced a durable mean reduction in the venous clinical severity score. The ulcer healing rates for the VLU+ cohort at 6, 12, 24, and 36 months were 38%, 47%, 52%, and 59%, respectively. The ulcer recurrence rates for the VLU+ cohort were 4%, 10%, 19%, and 30% at 6, 12, 24, and 36 months, respectively, with a median time to recurrence of 1.2 years. CONCLUSIONS Patients with active VLUs who underwent a first reintervention after initial IVS, on average, required an additional reintervention.

Abstract
BACKGROUND Chronic venous disease (CVD), comprising impaired lower limb venous return, will lead to chronic distal venous pressure overload manifested by various clinical signs and symptoms and resulting in diminished quality of life. The CEAP (Clinical, Etiology, Anatomy, and Pathophysiology) classification of CVD distinguishes six stages (C0-C6) using clinical, etiologic, anatomic, and pathophysiologic parameters. In the present study, we analyzed the effects of adapted physical activity (APA) and patient-oriented therapeutic education (PTE) programs on the clinical signs, symptoms, and quality of life of patients with CVD. METHODS Our analysis, in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) recommendations, included a search of PubMed, CINAHL and LiSSa databases, using a single search equation. RESULTS A total of 21 studies were selected for analysis. The analysis revealed first, that patients at stage C0 to C5 had had access to an APA program. This therapy alleviated the clinical signs and symptoms and improved the patients' quality of life. The beneficial effects of APA were greater in the programs that had included aquatic activities than in the program that were exclusively dry-land programs. Second, patients at stage C6 had predominantly followed a PTE program. This therapy showed beneficial effects on the clinical signs and symptoms. However, the quality of life had rarely been assessed. CONCLUSIONS At present, APA and PTE programs comprise useful and complementary therapeutic options for the care of patients with CVD. Two of the studies included in our review had evaluated the effects of combining these two approaches, notably in the context of balneotherapy, and reported promising results.

Abstract
OBJECTIVE Varicose vein is a vascular disorder that may cause negative impact on quality of life. However, little is known about the association between varicose vein and major depressive disorder. The aim of this study was to evaluate the risks of major depressive disorder among individuals with varicose veins. METHOD The study subjects of this retrospective cohort study were selected based on Chang Gung Research Database data from January 1st, 2005, to December 31st, 2015. We used ICD-9-CM codes 454 to determine the subjects diagnosed with varicose veins. We matched patients with varicose veins to participants without varicose veins at a 1:4 ratio by gender, age, and index date. The follow-up period for new onset major depressive disorder was extended to December 31st, 2017. The hazard ratios of major depressive disorder were estimated using Cox regression analysis with competitive risk model adjusting with gender, age, and comorbidities. RESULTS A total of 10,640 patients with varicose veins and 42,560 matched controls were enrolled. The varicose veins group had higher incidence rates of new onset major depressive disorder (adjusted hazard ratio 1.46; 95% confident interval, 1.17-1.82, p < 0.001). Compared with matched controls, varicose veins patients with or without venous ulcers had 2.26- and 1.39-times increased risk of developing new onset major depressive disorder, respectively. CONCLUSIONS Patients with varicose veins have an increased risk in developing major depressive disorder. Clinicians should be aware of mental health in patients with varicose veins, and psychosocial support is important for these patients.

Abstract
INTRODUCTION To determine whether the local administration of insulin glargine compared with placebo in nondiabetic patients with venous ulcers (VUs) leads to increased wound healing. METHODS A randomized controlled trial using a split-plot design was performed in 36 adults with leg VUs >25 cm2 and more than 3 mo of evolution. Each hemi-wound received either 10 UI insulin glargine or saline solution once a day for 7 d. Size of the wounds, thermal asymmetry, the number of blood vessels, and the percentage area of collagen content in wound biopsies were assessed at baseline and after 7 d of treatment. Blood capillary glucose was monitored once a day after the insulin injection. RESULTS After 7 d of treatment, the hemi-wounds treated with insulin glargine were significantly smaller, had less thermal asymmetry, more blood vessels, and more collagen content than the saline-treated side. Correlation between thermal asymmetry and the number of blood vessels was also found (r2 = 66.2, P < 0.001). No patient presented capillary glucose levels ≤3.3 mmol/L nor any adverse effects. CONCLUSIONS In nondiabetic patients with chronic VUs, the topical administration of insulin glargine seems to be safe and promotes wound healing and tissue repair after 7 d of treatment.

Abstract
OBJECTIVE The aim of the present study was to examine whether severe chronic venous disease (CVD) is associated with a greater risk of major adverse cardiovascular events (MACE) compared with mild CVD. METHODS Participants with CVD were prospectively recruited from outpatient vascular departments at two hospitals in North Queensland, Australia. CVD severity was ascertained by vascular specialists using the CEAP (clinical, etiologic, anatomic, pathophysiologic) classification. MACE, defined as myocardial infarction, stroke, or cardiovascular death, were identified from the outpatient follow-up and linked medical records. Kaplan-Meier and Cox proportional hazard analyses were used to examine the association of CVD severity with the occurrence of MACE. A subanalysis was performed in which participants with CEAP C5 and C6 (severe CVD) were compared with those with CEAP C2 to C4 (mild CVD). RESULTS A total of 774 participants were included and followed up for a median of 3.09 years (interquartile range, 1.09-8.14 years). The participants with C6 CVD (n = 69) had a threefold greater risk of MACE (hazard ratio, 3.03; 95% confidence interval, 1.02-9.03; P = .046) compared with those with C2 CVD (n = 326) after adjusting for other risk factors. Participants with severe CVD had an increased risk of MACE compared with those with mild CVD (adjusted hazard ratio, 2.37; 95% confidence interval, 1.12-5.04; P = .024). CONCLUSIONS Individuals with severe CVD have an increased risk of MACE compared with those with mild CVD, independently of traditional risk factors. Further research is required to clarify the cause of the excess risk.

Abstract
OBJECTIVE Patients requiring thermal or chemical ablation of below knee (BK) truncal veins often have their proximal saphenous veins treated initially and comprise a study population with multilevel, refractory chronic venous insufficiency. The study objective was to assess the outcomes after microfoam ablation of BK truncal and tributary veins in patients with a history of proximal great saphenous vein (GSV) ablation or stripping. METHODS A retrospective review of a prospectively maintained database was performed. All the patients who had undergone endovenous chemical ablation with commercially manufactured polidocanol microfoam for symptomatic BK truncal vein reflux after a previous saphenous ablation or stripping were identified. The patients had undergone duplex ultrasound scanning 48 to 72 hours after the procedure; those who had not adhered to the recommended follow-up protocol were excluded. The demographic data, CEAP (clinical, etiologic, anatomic, pathophysiologic) classification, venous clinical severity score (VCSS), procedure details, adverse thrombotic events, and follow-up data were abstracted. RESULTS Between April 2018 and April 2021, 201 limbs were treated for symptomatic superficial truncal vein reflux with microfoam ablation. Of the 201 limbs, 68 in 49 patients met the inclusion criteria for the present study. The veins treated included the BK GSV (n = 45) and small saphenous vein (n = 23). The median follow-up was 97 days (range, 33-457 days) for the entire cohort. Most patients (63%) had a preoperative CEAP classification of C4 to C6. The median preoperative VCSS was 12.5. All the limbs that had undergone microfoam ablation in this cohort had a previously treated proximal ipsilateral GSV, with either thermal ablation or stripping. The median postoperative VCSS after BK treatment decreased to 10 (P < .001). The closure rate at the last follow-up was 96%. The overall symptomatic relief was 78% at the last follow-up. The absolute ulcer healing rate during the study period was 64% (16 of 25 ulcers had healed). One patient had developed thrombus extension into the popliteal vein, which resolved with anticoagulation therapy. One asymptomatic patient had developed nonocclusive thrombus in a gastrocnemius vein after small saphenous vein ablation. Because she was asymptomatic, anticoagulation therapy was not prescribed. Postoperative pain, phlebitis, and swelling were reported in 12%, 12%, and 2% of patients, respectively, and all had resolved at the last follow-up visit. Three limbs treated with chronic oral anticoagulant agents had had recanalized truncal veins during the study period after initial closure. No pulmonary emboli or neurologic adverse events were reported. No symptoms of saphenous or sural nerve injury had occurred. CONCLUSIONS Endovenous chemical ablation with commercially manufactured polidocanol microfoam of BK truncal veins is a safe and effective treatment for patients with severe, refractory chronic venous insufficiency and prior saphenous interventions. This technique results in excellent overall closure rates and symptomatic relief with low adverse venous thrombotic events, across a wide range of CEAP classes.

Abstract
Lower extremity ulcerations contribute to significant morbidity and economic burden globally. Chronic wounds, or those that do not progress through healing in a timely manner, are estimated to affect 6.5 million people in the United States alone causing, significant morbidity and economic burden of at least an estimated $25 billion annually. Owing to the aging population and increasing rates of obesity and diabetes mellitus globally, chronic lower extremity ulcers are predicted to increase. Here, we explore the pathophysiology, diagnosis, and management of the most (and least) commonly seen lower extremity ulcers.

Abstract
OBJECTIVE The development of a venous leg ulcer (VLU) represents the most severe clinical manifestation of a chronic venous disease. Despite major progress, there is a limited understanding of VLU pathogenesis and wound healing biology. Treatment of VLUs remains a serious challenge for physicians of different specialties. This communication focuses on describing the rationale and scientific basis for topical wound care in the management of VLUs. METHODS A literature review was performed to summarize methods with proven efficacy in VLU management. A systematic literature search was also performed to identify new evidence from the randomized controlled trials published within 2014-2021. The scientific challenges, clinical practice concerns, economic obstacles, and possible directions for further research have been discussed. RESULTS Hundreds of topical products have been advertised for the treatment of VLUs. Published data on topical treatment of venous ulcers is insufficient, scattered, weak, and has significant methodological flaws. Forty-three randomized controlled trials on topical treatment of VLUs have been published within 2014-2021. Clinical practice guidelines need to be updated. Major gaps in knowledge have been identified, and suggestions for future research directions have been provided. CONCLUSIONS The American Venous Forum Research Committee would like to bring attention to topical wound care for VLUs as a critical gap in knowledge, and encourage scientists, practitioners, and industry to collaborate to fill this gap.

Abstract
OBJECTIVE Venous insufficiency is often not readily recognized as a contributing etiology to nonhealing wounds by nonvascular surgery specialists, potentially delaying appropriate treatment to achieve wound healing and increasing healthcare costs. The objective of the present study was to understand the time and resources used before the definitive treatment of venous ulcers. METHODS A single-institution retrospective medical record review of C6 patients undergoing radiofrequency saphenous and perforator vein ablation from May 2016 to January 2018 identified 56 patients with 67 diseased limbs. The numbers of inpatient, emergency department, and wound care visits and the intervals to vein ablation from the initial evaluation of the ulceration by a healthcare provider were collected. The demographics, comorbidities, previous venous interventions, wound characteristics, duplex ultrasound imaging, and available wound healing follow-up through July 2018 were assessed for all patients. RESULTS For the 67 limbs examined, 588 total healthcare visits were performed for wound assessment before a referral to a vascular surgeon, with 413 visits at a wound care center (70% of all visits). Other specialty visits included emergency medicine (17.9% of limbs) and rheumatology (22.4% of limbs). Six patients (nine limbs) were admitted to inpatient services for treatment of their ulceration. Overall, the patients were seen an average of 8.6 ± 9.7 times for their ulcer with the wound center before determination of a contributing venous etiology and subsequent treatment. These visits translated to a median of 230 days (interquartile range, 86.5-1088 days) between the first identification of the ulcer by healthcare providers and subsequent accurate diagnosis and definitive treatment of their venous disease with radiofrequency saphenous and perforator vein ablation. After intervention, 18.64% of the limbs had healed at 1 month, 33.92% had healed at 3 months, 50% had healed at 6 months, and 82.92% had healed by 12 months. CONCLUSIONS An earlier and accurate diagnosis of the venous contribution to ulcers and subsequent appropriate treatment of venous etiologies in wound formation by a vascular venous specialist could significantly improve healing and minimize resource usage.

Abstract
OBJECTIVE To compare the use of high saphenous ligation and stripping, radiofrequency ablation, and subfascial endoscopic perforator surgery for the treatment of active venous ulcers. METHODS One hundred ninety-five (n = 195) subjects who were treated for venous leg ulcers were enrolled between 2009 and 2014. Three groups were formed (Group A: high saphenous ligation and total stripping, Group B: radiofrequency ablation of the great saphenous vein + perforators, and Group C: radiofrequency ablation of the great saphenous vein + subfascial endoscopic perforator surgery) (n = 65 for each group). The venous clinical severity score for baseline, 1st, 6th, and 12th months, great saphenous vein occlusion at the 1st, 6th, and 12th months, and ulcer rates for the 1st, 2nd, 3rd, 4th, and 5th years were recorded. RESULTS For venous clinical severity score, only the first month decrease was significant for the subfascial endoscopic perforator surgery group (p = 0.001). Great saphenous vein occlusion was higher at the 6th and 12th months for the high saphenous ligation and stripping and subfascial endoscopic perforator surgery groups than for the radiofrequency ablation group (p = 0.036 and p = 0.037). The rate of ulcers for the subfascial endoscopic perforator surgery group was lower at the second, third, fourth, and fifth years (p = 0.011). No significant difference was found between groups for the five-year recovery rates (p > 0.05). CONCLUSION Subfascial endoscopic perforator surgery technique in conjunction with radiofrequency ablation of axial vein was superior to both high saphenous ligation and stripping and radiofrequency ablation of axial and perforators for ulcer healing.

Abstract
BACKGROUND Venous leg ulceration is a widespread, debilitating pathology with high recurrence rates. Conservative treatment using graduated compression dressings may be associated with unacceptable ulcer recurrence rates. Early superficial venous ablation encourages ulcer healing and reduces recurrence. However, many of this cohort display concomitant ilio-caval stenosis, which further contributes to lower limb venous hypertension and ulceration. An approach that combines early superficial venous ablation with early treatment of ilio-caval stenotic disease may significantly improve ulcer healing and recurrence rates. We question whether early iliac vein interrogation with intravascular ultrasound (IVUS), stenting of significant occlusive disease plus superficial venous ablation, in patients with active venous leg ulceration, will produce superior ulcer healing to standard therapy. METHODS This is a prospective, multi-centre, randomised controlled, feasibility trial recruiting patients with lower limb venous ulceration and saphenous venous incompetence. Patients will be randomised to undergo either truncal ablation and compression therapy or truncal ablation, simultaneous iliac interrogation with intravascular ultrasound and stenting of significant (> 50%) iliac vein lesions plus compression therapy. The primary feasibility outcome will be the rate of eligible patient participation while the primary clinical outcomes will be ulcer healing and procedural safety. Secondary outcomes include time to healing, quality of life and clinical scores, ulcer recurrence rates and rates of post-thrombotic syndrome. Follow-up will be over a 5-year period. This feasibility trial is designed to include 60 patients. Should it be practicable a total of 594 patients would be required to adequately power the trial to definitively address ulcer-healing rates. DISCUSSION This trial will be the first randomised trial to examine the role iliac interrogation and intervention in conjunction with standard operative therapy in the management of venous ulceration related to superficial truncal venous incompetence.

Abstract
OBJECTIVE Venous leg ulcers (CEAP [clinical, etiologic, anatomic, pathophysiologic] class 6) represent the most severe form of chronic venous insufficiency. As closure techniques for superficial venous reflux evolve, direct outcome comparisons of treatments are integral, because many studies have already demonstrated that early endovenous intervention improves wound healing. The present study compared the rates of venous wound healing between two techniques of superficial vein closure: ClosureFast radiofrequency ablation (RFA) and adhesive closure (VenaSeal; both Medtronic, Inc, Minneapolis, Minn). METHODS We performed a multi-institutional retrospective review of all patients with CEAP class 6 who had undergone closure of their truncal veins from 2015 to 2020. Patients undergoing ClosureFast RFA were compared with those undergoing VenaSeal adhesive closure. The primary endpoint was the interval to wound healing from initial vein closure. The secondary endpoints included ulcer recurrence and infection rates. Bivariate analysis involved the χ2, Fisher exact, t, and Wilcoxon rank sum tests. Multivariate linear regression analysis was used to examine the factors affecting the time to wound healing in the most predictive model. Statistical significance was defined as P < .05. RESULTS A total of 119 patients with CEAP 6 were included, with a median follow-up of 105 days (interquartile range, 44-208 days). Of the 119 limbs, 68 were treated with RFA and 51 with VenaSeal. Significantly more patients undergoing RFA had had a history of deep vein thrombosis (29% vs 10%; P = .01) and deep venous reflux (82% vs 51%; P = .003). The VenaSeal patients were older (72 years vs 65 years; P = .02) with a greater rate of coronary artery disease (16% vs 37%; P = .01). The median time to wound healing after the procedure was significantly shorter for VenaSeal than for RFA (43 vs 104 days; P = .001). Two RFA patients developed a postprocedure infection. The ulcer recurrence rate was 19.3% (22.1% for RFA vs 13.7% for VenaSeal; P = .25). On multivariate analysis, the treatment modality was the only significant predictor of the time to wound healing. When stratified by ulcer size as small (<3 cm2) vs large (>3 cm2), VenaSeal closure healed the wounds significantly faster for all ulcers. CONCLUSIONS ClosureFast and VenaSeal are both safe and effective treatments to eliminate truncal venous insufficiency. VenaSeal showed a superior time to wound healing compared with ClosureFast in both large and small ulcers.

Abstract
Introduction Endovenous techniques such as ultrasound guided foam sclerotherapy, thermal methods, or glues are generally recommended to occlude incompetent veins. However, these methods can be technically challenging and risky for patients with severe atrophic skin disorders like lipodermatosclerosis or atrophie blanche. High intensity focused ultrasound (HIFU), which has been shown to coagulate and occlude veins successfully, may offer an alternative method. This case report details ultrasound guided HIFU to occlude non-invasively a refluxing perforator vein causing active ulcers. Report A 95 year old man presented to the Institute for Functional Phlebology (Melk, Austria) with painful recurrent ulcers in his left medial calf. His limb was scored C2,3,4a, b,6, Ep, Ap, Pr,18 according to the Clinical, Etiology, Anatomic, Pathophysiology (CEAP) classification. Lower limb ultrasound revealed a refluxing posterior tibial perforating vein, measuring 2.7 mm in diameter at the level of the fascia. Extracorporeal HIFU pulses were delivered to this vein with the Sonovein device (Theraclion, Malakoff, France). Sonication was applied for eight seconds at a mean acoustic power of 80 W. The patient was followed up for three months post-treatment and occlusion was evaluated by duplex ultrasound. There were no complications during treatment or follow up. Three months after the treatment, reflux was abolished and the two initially active ulcers had healed. Discussion Although this is an early report, this study shows that HIFU can be successful in ablation of incompetent perforator veins in the treatment of venous leg ulcers. Endovenous methods are not suited to all patients with severe skin disorders. High intensity focused ultrasound can treat venous leg disorders non-invasively. Treatments have been performed on a refluxing perforator vein causing active ulcers. Short-term results showed that this technique is as good as other thermal therapies.

Abstract
OBJECTIVE Thrombus extension into the deep venous system following superficial vein chemical ablation with Varithena polidocanol microfoam has been reported. The objective of this study was to assess the effect of intraoperative improved techniques during treatment for patients with symptomatic varicose veins and their impact on extension of thrombus into deep veins. METHODS A retrospective review of a prospectively maintained database was performed. All patients who underwent endovenous chemical ablation with polidocanol microfoam (Varithena, Boston Scientific, Marlborough, Mass) for symptomatic superficial axial and tributary vein reflux were identified. Patients had postoperative duplex (48-72 hours) scanning after the procedure; those who did not adhere to the recommended follow-up were excluded. Demographic data, CEAP Classification, Venous Clinical Severity Score, procedure details, and follow-up data were abstracted. RESULTS Between April 2018 and August 2020, 157 limbs in 122 patients were treated with Varithena microfoam; 129 limbs in 99 patients met our inclusion criteria. Veins treated included the great saphenous vein (n = 89), anterior accessory saphenous vein (n = 15), small saphenous vein (n = 14), and tributary veins (n = 56). Adjunctive techniques during treatment included intraoperative elevation of the limb to greater than 45°, ultrasound mapping and digital occlusion of large perforator veins, limitation of foam volume per session, injection of sterile saline before treatment, and compression of the limb in the elevated position. The preoperative Venous Clinical Severity Score was 11.4 and decreased after treatment to 9.7. The immediate closure rate was 95% with 81% overall symptomatic relief at last follow-up. The mean follow-up was 113.5 days for the entire cohort; two limbs (1.5%) required postoperative anticoagulation for thrombus extension into the deep venous system (common femoral vein n = 1; popliteal vein n = 1) postoperatively for a mean of 22 days. Both resolved with anticoagulation. One asymptomatic limb developed a femoral vein deep venous thrombosis and one symptomatic late deep venous thrombosis was noted 4 months after the procedure. Postoperative pain and phlebitis were reported in 15.6% and 14.8% of patients, respectively, and all had resolved at last follow-up. No pulmonary emboli were noted and no neurologic or visual adverse events were recorded. CONCLUSIONS Adjunctive techniques during microfoam ablation decreased thrombotic complications in our series compared with those reported in earlier phase III clinical trials. Excellent early closure and symptomatic improvement were also noted. Endovenous microfoam ablation with Varithena is a safe and effective nontumescent, nonthermal alternative to laser and radiofrequency ablation.

Abstract
OBJECTIVE We evaluated the effect of first-visit foam sclerotherapy compared with scheduled treatment for patients with venous ulceration. METHODS The study design was a retrospective comparative study. From December 2009 to October 2019, a total of 245 venous ulcers in 214 patients (including recurrent ulcers) were treated at Oulu University Hospital. Of these 245 venous ulcers, 143 were treated with first-visit foam sclerotherapy (group A) and 102 with scheduled treatment (group B). All patients received endovenous ablation (foam sclerotherapy and/or endothermal ablation) and compression therapy to promote venous ulcer healing. The primary outcome was the interval to ulcer healing, determined by Kaplan-Meier survival analysis. The secondary outcomes included the time to ulcer healing from the receipt of referral and ulcer recurrence. RESULTS The median time to ulcer healing was 2.3 months for group A and 3.2 months for group B (P = .002). The estimated median ulcer healing times after referral for a first session of endovenous ablation were 2.7 months with a delay of <1 month from the referral, 3.3 months with a delay of 1 to 2 months, and 5.0 months with a delay of >2 months (P = .002). In group A, recurrent ulcers were recorded for 11 patients (7.7%). In group B, recurrent ulcers were recorded for 12 patients (11.8%; P = .281). CONCLUSIONS The results of the present retrospective comparative study support first-visit foam sclerotherapy as an effective method to initiate endovenous ablation to promote venous ulcer healing. In venous ulcers, delays to endovenous ablation should be avoided whenever possible.

Abstract
BACKGROUND Chronic leg ulcers affect a large portion of the adult population and cause a significant social and economic impact, related to outpatient and hospital care, absence from work, social security expenses, and reduced quality of life. The correct diagnosis and therapeutic approach are essential for a favorable evolution. OBJECTIVE To gather the experience of Brazilian dermatologists, reviewing the specialized literature to prepare recommendations for the diagnosis and treatment of the main types of chronic leg ulcers. METHODS Seven specialists from six university centers with experience in chronic leg ulcers were appointed by the Brazilian Society of Dermatology to reach a consensus on the diagnosis and therapeutic management of these ulcers. Based on the adapted DELPHI methodology, relevant elements were considered in the diagnosis and treatment of chronic leg ulcers of the most common causes; then, the recent literature was analyzed using the best scientific evidence. RESULTS The following themes were defined as relevant for this consensus - the most prevalent differential etiological diagnoses of chronic leg ulcers (venous, arterial, neuropathic, and hypertensive ulcers), as well as the management of each one. It also included the topic of general principles for local management, common to chronic ulcers, regardless of the etiology. CONCLUSION This consensus addressed the main etiologies of chronic leg ulcers and their management based on scientific evidence to assist dermatologists and other health professionals and benefit the greatest number of patients with this condition.

Abstract
OBJECTIVES To investigate whether radiofrequency endovenous ablation (RFA) of saphenous and perforating veins increases venous leg ulcer (VLU) healing rates and prevents ulcer recurrence. METHOD This prospective, open-label, randomized, controlled, single-center trial recruited 56 patients with VLU divided into: compression alone (CR, N = 29) and RFA plus compression (RF, N = 27). Primary endpoints were ulcer recurrence rate at 12 months; and ulcer healing rates at 6, 12, and 24 weeks. Secondary endpoints were ulcer healing velocity; and Venous Clinical Severity Score (VCSS). RESULTS Recurrence was lower in the RF group (p < .001), as well as mean VCSS after treatment (p = .001). There were no significant between-group differences in healing rates. Healing velocity was faster in the RF group (p = 0.049). In the RF group, 2 participants had type 1 endovenous heat-induced thrombosis (EHIT). CONCLUSIONS RFA plus compression is an excellent treatment for VLU because of its safety, effectiveness, and impact on ulcer recurrence reduction and clinical outcome.Registration: Clinicaltrials.gov, NCT03293836, clinicaltrials.gov.

Abstract
OBJECTIVE Iliocaval outflow obstruction was investigated in patients with venous ulcers caused by primary superficial disease and chronic deep vein disease METHODS: After clinical assessment, patients with healed or active venous leg ulcers underwent lower extremity duplex ultrasound examination to identify the presence of venous disease in the superficial, deep and perforating systems. Bilateral contrast venography and intravascular ultrasound examination were then performed to determine the presence and degree of iliocaval obstructive lesions. RESULTS This retrospective study included a total of 59 patients with 71 legs presenting active or healed ulcer. There were 16 limbs (22.5%) with superficial venous reflux associated with normal infrainguinal deep veins (group I) and 55 limbs (77.5%) with infrainguinal post-thrombotic deep venous disease (group II). Using venography and intravascular ultrasound examination, the incidence of >50% of venous obstruction in the iliocaval system in groups I and II were 75% and 83.6%, respectively. All obstructive lesions in group I were nonthrombotic. However, group II included thrombotic, nonthrombotic and combinations of the two types of obstructions. Group II had more ulcers (1.73 ± 1.3 vs 1.17 ± 0.5; P = .03), larger ulcers (>6 cm in 34.1% vs 8.3%), longer duration of ulcers (71.3 ± 110.5 months vs 37.9 ± 40.4 months; P = .03), smaller diameter of refluxing superficial veins (7.7 ± 2.6 mm vs 15.1 ± 6.6 mm; P = .001), and higher incidence of occluded iliocaval systems (18 [32.7%] vs 0; P = .003) than group I. After the exclusion of bilateral cases and thrombotic obstructions, the incidence of >50% nonthrombotic obstruction in ipsilateral and contralateral sides was 76.5% and 24.4%, respectively (P = .003). CONCLUSIONS The results of this study revealed that the majority of patients with venous ulcers with either infrainguinal primary superficial or post-thrombotic deep venous disease had an element of iliocaval venous obstruction.

Abstract
Compression therapy is the basis for treating the cause of venous ulcers and preventing recurrence. Various systems are currently available for applying compression and adapting them to patients' needs can improve adherence to treatment. Understanding the principles that underlie compression therapy is essential for success. Although this paper focuses mainly on venous ulcers, compression has also proven beneficial for other conditions, such as lymphedema and wounds resulting from injury or inflammation.

Abstract
BACKGROUND Limb compression is a key component of protocols used to heal venous leg ulcers (VLUs). A novel ambulatory pneumatic compression device was tested in comparison with multilayered bandage (MLB) compression systems for the treatment of VLUs in a prospective randomized clinical trial. METHODS Patients with VLUs measuring 1.5 to 50 cm2 with duration of 1 to 24 months were randomized to treatment with a pneumatic compression device, the ACTitouch adaptive compression therapy (ACT) system (Tactile Medical, Minneapolis, Minn), or MLB. The ACT group patients were seen in the clinic at weeks 1, 2, 4, 6, 9, 12, and 16 or until wounds healed; the MLB group was seen weekly for bandage and dressing changes for 16 weeks or until wounds healed. All other aspects of VLU care were standardized between the two groups. The primary study objective was to compare the VLU percentage area reduction at 16 weeks in the ACT group compared with the MLB group. RESULTS There were 56 patients randomized to treatment with ACT (n = 26) or MLB (n = 30). In the ACT group, five patients exited because of skin or wound problems related to the ACT device and five withdrew because of the inconvenience of using the device. Therefore, the trial was halted before full randomization so improvements to the ACT device could be made. Data collected on 42 patients who were able to tolerate treatment for the 16-week study period (per protocol group) showed that both groups experienced similar rates of wound healing. In the per protocol population, the percentage area size reduction was greater for the ACT group compared with the MLB group (83.8% vs 70.5%, respectively), whereas no significant differences were noted in the percentage of wounds that healed by 16 weeks (60.0% vs 63.0%, respectively). CONCLUSIONS In this truncated clinical trial, a novel dual-mode ambulatory compression device, when tolerated, achieved wound healing results similar to those with MLB for chronic VLUs. The device requires modifications to improve the patient's comfort and ease of use. However, this mode of therapy appears to have promise for improving the cost-effectiveness of treatment for chronic VLUs.

Abstract
OBJECTIVE The objective of this study was to define the current forms of treatment in a contemporary population of lymphedema (LED) patients for LED related to breast cancer, the most prevalently diagnosed LED comorbidity in Western countries, and phlebolymphedema with venous leg ulcer (PLEDU), a sequela of chronic venous disease. The goals of LED therapy are to reduce edema, thereby improving function and related symptoms, and to improve skin integrity to prevent development of infection. Treatment is generally nonsurgical: conservative care, including complex physical therapy, manual lymphatic drainage, and compression bandaging; or pneumatic compression device (PCD) therapy by a simple nonprogrammable device or an advanced programmable device. METHODS To determine the frequency of individual types of treatment for LED and their relationship to breast cancer-related lymphedema (BCRL) and PLEDU, we queried claims from a deidentified Health Insurance Portability and Accountability Act-compliant commercial administrative insurance database with >165 million members. A total of 26,902 patients identified with LED who had been enrolled with continuous medical benefits for 12 months before and after the index date for the complete years 2012 through 2016 were separated into four treatment categories: no treatment, conservative care, simple PCD (SPCD), and advanced PCD. LED treatment was related to the BCRL and PLEDU comorbidities. RESULTS BCRL patients, who represented 32.1% of all study patients, made up 41% of all patients receiving conservative care and 24% of patients receiving PCD therapy. By contrast, PLEDU patients (9.6% of study patients) were proportionally under-represented in the conservative care group (7.8%) but composed a disproportionately high share of the PCD therapy group (17.7%). PLEDU patients represented 23.5% of all LED patients prescribed SPCD therapy, whereas BCRL patients composed 10.3% of total LED patient SPCD prescriptions (P < .001). CONCLUSIONS Our analysis of a large health care administrative database showed clear differences between the way BCRL and PLEDU patients are treated. Compared with BCRL patients, PLEDU patients were less likely to receive conservative care and more likely to be prescribed SPCDs for pneumatic compression therapy. These differences suggest that lymphatic therapy may be undervalued for treatment of chronic venous swelling and prevention and treatment of PLEDU.

Abstract
In chronic venous ulcers (CVUs), which account for up to 75% of leg ulcers, the inflammatory stage of wound healing fails to down-regulate, preventing progression to proliferation, remodeling and eventual epithelialisation. The roles of reactive oxygen species (ROS) in the oxidative burst and pathogen killing are well known, but ROS also have important functions in extra-cellular and intra-cellular signalling. Iron deposition, resulting from venous reflux, primes macrophages towards a persistent inflammatory response, with ongoing stimulation by bacteria potentially playing a role. Generation of excessive ROS by activated inflammatory cells causes tissue destruction and disintegration of the dermis, and then at later stages, a failure to heal. Here, we review the evidence for ROS in CVU formation and in normal and delayed healing. We also discuss how ROS modulation might be used to influence the healing of these complex wounds, which cause long-term morbidity and are associated with a significant financial burden to healthcare systems.

Abstract
OBJECTIVE To evaluate the impact of three treatment modalities, superficial truncal vein ablation, perforator vein ablation, and deep venous stenting on venous leg ulcer (VLU) healing, as well as their cumulative effect on ulcer healing, in an attempt to establish the best algorithm for the treatment of chronic and recalcitrant VLUs. METHODS Multicenter retrospective cohort study using a standardized database to evaluate patients with chronic venous ulcers treated between January 2013 and December 2017. RESULTS Eight-hundred thirty-two consecutive patients with VLU were identified at 11 centers in the United States. All patients were initially managed with wound care and compression for at least 2 months. Compression and wound care management alone, used in 187 patients, led to ulcer healing in 75% of patients by 36 months. Ulcer recurrence in patients managed without surgery at 6, 12, and 24 months was 3%, 5% and 15%, respectively. Five hundred twenty-eight patients underwent ablation of incompetent superficial veins, and 344 of those also underwent incompetent perforator ablation. Patients who underwent truncal vein ablation alone had an ulcer healing rate of 51% at 36 months. Patients who received both superficial and perforator ablation were significantly younger, and had a 17% improvement in healing at 36 months (68% vs 51%, respectively), but there was no impact of combined superficial and perforator ablations on ulcer recurrence rates. One hundred thirty-four patients had stenosis of one of more lower extremity deep veins and 95 (71%) underwent endovenous stenting. Ulcer healing and recurrence rates for those who underwent stent placement alone was 77% and 27%, respectively, at 36 months. Patients who underwent deep venous stenting and ablation of both incompetent truncal and perforator veins had an ulcer healing rate of 87% at 36 months and ulcer recurrence of 26% at 24 months. CONCLUSIONS This study demonstrates that correction of superficial truncal vein reflux, as well as deep vein stenosis, both contribute to healing of VLU. Patients who fail to heal their VLU after superficial and perforator ablation should have the iliocaval system imaged to identify hemodynamically significant stenoses or occlusions amenable to stenting, which facilitates venous ulcer healing even in patients with large ulcers.

Abstract
OBJECTIVE Endovenous radiofrequency ablation (RFA) is one of the most popular techniques for correcting superficial vein reflux. However, the effectiveness of RFA of superficial vein reflux in patients with active or healed venous leg ulcer (VLU) is unknown. Accordingly, the objective of this study was to evaluate the healing rate, the recurrence rate, and the factors significantly associated with healing and recurrence in patients with active or healed VLU who had superficial venous reflux treated with RFA. METHODS We retrospectively reviewed all healed VLU or active VLU patients treated with RFA at the Division of Vascular Surgery, Department of Surgery, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand, during January 2011 to December 2017 to evaluate the rate of VLU healing and recurrence. Time to healing and time to ulcer recurrence were determined by Kaplan-Meier survival analysis. Risk factors were assessed to determine their association with VLU healing and recurrence by Cox regression survival analysis. RESULTS RFA of the great saphenous vein (n = 56), anterior accessory saphenous vein (n = 5), or both (n = 1) was performed on 62 limbs with active (n = 32) or healed (n = 30) VLUs. The mean age of patients was 65.4 ± 9.8 years, and 80% were female. Deep venous insufficiency was present in 10 limbs (16%). Pathologic perforating vein was found in 17 patients (27%). Concomitant ultrasound-guided foam sclerotherapy (UGFS) of the pathologic perforating vein was performed in 12 limbs (19%). Concomitant phlebectomy was performed in 19 limbs (31%). The median follow-up time was 753 days after RFA. VLU healed in 31% of patients at 3 months, in 56% at 6 months, and in 66% at 1 year after RFA. Concomitant UGFS of the pathologic perforating vein was the only factor significantly associated with VLU healing (hazard ratio, 2.84; 95% confidence interval, 1.07-7.55; P = .037). VLU recurrence was found in 8% of patients at 1 year, in 14% at 2 years, and in 23% at 3 years after RFA. Deep vein reflux was the only identified risk factor for VLU recurrence (hazard ratio, 3.72; 95% confidence interval, 1.05-13.21; P = .042). CONCLUSIONS UGFS of the pathologic perforating vein at the time of RFA of saphenous vein reflux improved VLU healing. VLU recurrence was more frequent in patients with concomitant deep vein reflux. The authors suggest performing UGFS of the pathologic perforating vein at the time of RFA to improve VLU healing and monitoring of patients with associated deep vein reflux for ulcer recurrence.

Abstract
BACKGROUND Venous leg ulcers represent the most common chronic wound problem managed in Australian primary care. Despite the prevalence of the condition, there is an evidence-practice gap in both diagnosis and management of venous leg ulcers. OBJECTIVE We used the Theoretical Domains Framework to identify barriers and enablers perceived by primary care practitioners in implementing venous leg ulcer guidelines in clinical practice. DESIGN We collected data to explore the experiences of practice nurses and general practitioners related to their use of clinical practice guidelines in management of venous leg ulcers. SETTING(S) We recruited participants from primary care settings located in metropolitan and rural areas across Victoria, Australia. PARTICIPANTS We recruited general practitioners (15) and practice nurses (20). METHODS We conducted 35 semi-structured face-to-face and telephone interviews. Content analysis of health practitioners' statements was performed and barriers to implementing clinical practice guidelines were mapped across the Theoretical Domains Framework theoretical domains. RESULTS Six main domains from the Theoretical Domains Framework (Environmental context and resources, Knowledge, Skills, Social influences, Social/Professional Role and Identity and Belief about Capabilities) best explained these barriers and enablers. Many participants were not aware of venous leg ulcer clinical practice guidelines. Those that were aware, stated that finding and accessing guidelines was challenging and most participants relied on other sources of information. Venous leg ulcer management was greatly influenced by professional experience and suggestions from colleagues. Other barriers included busy clinical practice, absence of handheld Doppler ultrasonography, insufficient skills and a lack of confidence related to the use of technology to rule out arterial involvement prior to compression application, a particular skill related to venous leg ulcer management that will impact on healing outcomes. CONCLUSIONS We identified a number of barriers and the lack of enablers that influence the uptake of venous leg ulcer clinical practice guidelines in primary care. This paper adds a theoretically sound, systematic approach for understanding and addressing the behaviour change required to improve translation of venous leg ulcer clinical practice guidelines in clinical practice. Tweetable abstract: The need to optimise venous leg ulcer clinical practice guidelines (CPG) has never been greater as the current estimate of health cost is AUD3billion and increasing due to rising epidemics of diabetes and obesity. We found most primary care health practitioners are unaware of CPG and this will impact on health and healing outcomes in Australian primary care.

Abstract
Venous ulcers are the most severe manifestation of post-thrombotic syndrome (PTS). We have previously demonstrated that formation of compact fibrin clots resistant to lysis is observed in patients following deep-vein thrombosis (DVT) who developed PTS. The current study investigated whether unfavourable fibrin clot properties can predict post-thrombotic venous ulcers. In a cohort study on 186 consecutive patients following DVT, we determined plasma fibrin clot characteristics, including clot permeability and lysability, inflammatory markers, thrombin generation, fibrinolysis proteins at 3 months since the index event. Occurrence of PTS and venous ulcers was recorded during follow-up (median, 53; range 24 to 76 months). Fifty-seven DVT patients (30.6%) developed PTS, including 12 subjects (6.45%) with a venous ulcer (4 individuals with recurrent ulcers). Patients who developed ulcers compared with the remainder had at enrolment 13.0% lower clot permeability (Ks), 17.4% longer clot lysis time (CLT), 13.1% longer lag phase of clot formation, and 5.0% higher maximum absorbance, with no difference in fibrinogen, C-reactive protein, and thrombin generation. The baseline prothrombotic fibrin clot phenotype (Ks ≤ 6.5 × 10-9 cm2 and CLT > 100 min) was associated with a higher risk of ulcers [hazard ratio (HR), 5.37; 95% confidence interval (CI), 1.3-21.5]. A multivariate model adjusted for age, sex, and fibrinogen showed that independent predictors of the ulcer occurrence were body mass index (HR 1.53; 95% CI 1.30-1.86), CLT (HR 1.43; 95% CI 1.04-2.05), and α2-antiplasmin (HR 0.95; 95% CI 0.90-0.99). This study suggests that formation of denser fibrin clots with impaired fibrinolysis predisposes to post-thrombotic venous ulcers.

Abstract
INTRODUCTION This prospective study of foam sclerotherapy for varicose veins aimed to determine the outcomes of treatment including ulcer healing and complication rates in our unit. Data were collected prospectively over a 10-year period and maintained on a database by our vascular sciences unit, which performed the planning and post-treatment venous duplex scans. Patients undergoing treatment due to venous ulceration were identified from this database. An initial cohort of patients underwent a follow-up scan and assessment at one year. MATERIALS AND METHODS Patients were treated with foam sclerotherapy, in multiple sessions if required, to occlude all incompetent superficial veins greater than 3 mm in size. We used 3% sodium tetradecyl sulphate as our sclerosing agent, according to our departmental protocol, followed by a period of compression therapy. Patients underwent pre- and post-treatment scans to assess venous competence, the effects of treatment and any complications that arose. RESULTS We identified 336 patients treated for clinical, aetiological, anatomical and pathophysiological stage 5/6 venous ulceration. At six weeks post-treatment, 21% had fully healed ulcers and a further 46.1% were clinically improving with no further venous incompetence. The remainder continued treatment. An initial cohort of 162 patients was assessed at one year and 77.1% ulcers remained healed. The remainder demonstrated some venous incompetence and ultimately 12.5% required further treatment. Our complication rates were similar to those quoted in published meta-analyses including a deep vein thrombosis rate of 1.16%. CONCLUSIONS Foam sclerotherapy remains a useful treatment option for venous ulceration with a low morbidity rate.

Abstract
BACKGROUND Venous ulcers are painful, recurrent, and difficult to heal. Electronic medical records (EMRs) are often not optimized to track wounds. Specialized wound care programs may not interface with office-based records, creating a need to standardize the process of venous ulcer measurement and dressing documentation within existing systems. This work describes the creation of an EMR protocol to track venous ulcer size, to standardize dressings, to address related health issues, and to improve education of the patient. We hypothesized that the institution of an EMR protocol to track clinical features of venous ulcer patients, including wound size and health status, would facilitate wound healing. METHODS We performed a retrospective review of a prospective database from September 2014 to May 2017. Modifications to the EMR included the formation of a venous ulcer patient list, a dressing tracker, calculation of total ulcer area, graphing of ulcer size over time, and images of the wound area. Patient education materials were created through the EMR and loaded into an automatic end-visit printout that emphasized smoking cessation, weight loss, and consultation with specialty services as necessary. Quarterly meetings with the supervising physician were established to review each patient's wound progress and to target areas of improvement. RESULTS During the study period, 204 patients with chronic C5 and C6 disease were observed. Before the start of the project, the healing rate was 53.3%. Wound healing rates improved from 59.5% (quarter 1) to 77.94% (quarter 8). In the quarter before the project started, there were no patients who had quit or cut down on smoking or smokeless tobacco, no patients who were referred for weight loss consultation, and nine who were already patients of bariatric surgery. During the study period, 29% of patients quit smoking, 19% decreased smoking, and 20% cut down smokeless tobacco use. There were 54 patients who underwent advanced arterial evaluation; 175 patients underwent sclerotherapy and 137 patients had endovenous thermal ablation to treat axial reflux in the affected limb. The EMR modification project took 13 months to craft and to implement, with approximately 8 hours of meeting time from the surgical team. CONCLUSIONS A comprehensive care model for venous ulcer patients through EMR modification improved overall patient care, increased communication between providers, and facilitated ulcer healing. EMR modification can be introduced with an acceptable time investment on the part of both the provider and the institutional information technology team.

Abstract
Klippel-Trenaunay syndrome is a rare disorder consisting of the triad of vascular and/or lymphatic malformations, capillary malformations, and soft tissue or bony hypertrophy. Symptom control is the mainstay of treatment for these patients, with many of the symptoms never fully being relieved. In this case report, we present the case of a 46-year-old man with chronic lower extremity ulcerations unresponsive to wound care therapy. Owing to the chronic nature of his wounds and associated pain, reconstruction of his iliac vein was performed using polytetrafluoroethylene graft and an arteriovenous fistula.

Abstract
OBJECTIVE Chronic venous leg ulcers (VLUs) affect up to 2% of the general population, resulting in a significant socioeconomic burden. Placental tissue that contains mesenchymal stem cells and active growth factors has been shown to be beneficial in healing of chronic wounds. We compared the efficacy of a human viable wound matrix (hVWM) of cryopreserved placental tissue for the treatment of refractory VLUs with standard therapy. METHODS This prospective single-center open-label single-arm study enrolled patients with Clinical, Etiology, Anatomy, and Pathophysiology clinical class C6 VLUs. The ulcers of all enrolled patients had failed to heal after a trial of standard therapy of at least 12 weeks, which included weekly multilayer compression therapy along with local wound care. The same patients subsequently received application of hVWM (Grafix; Osiris Therapeutics, Columbia, Md) every 1 to 2 weeks in addition to standard therapy. Healing with hVWM therapy was then compared with standard therapy, with each patient serving as his own control. RESULTS There were 30 VLUs in 21 consecutive eligible patients who were enrolled in the study. All patients were men with an average age of 67 years (standard deviation [SD], ±10.8 years), and the average area of venous ulcers before hVWM initiation was 12.2 cm2 (SD, ±14.6 cm2; range, 3.3-12.3 cm2). Duplex ultrasound confirmed superficial or deep system venous reflux in all patients. Complete ulcer healing was achieved in 53% (16/30) of VLUs refractory to standard therapy after application of hVWM. There was a mean reduction in wound surface area by 79% (SD, ±27.3%; P < .001 compared with standard therapy) after a mean treatment time of 10.9 weeks. Eighty percent of VLUs were reduced in size by half compared with 25% with standard therapy (P < .001). The mean rate of reduction in ulcer area after hVWM applications was 1.69% per day vs 0.73% per day with standard therapy (P = .01). CONCLUSIONS Cryopreserved placental tissue (hVWM) improves healing processes to achieve complete wound closure in a significant proportion of chronic VLUs refractory to standard therapy. Adjunctive therapy with hVWM provides superior healing rates in refractory VLUs.

Abstract
BACKGROUND Guidelines as well as multiple RTCs support the use of intermittent pneumatic compression (IPC) for the treatment of venous leg ulcers when conservative measures fail. Unfortunately, the clinical usefulness of IPC is significantly limited by the physical limitations of pneumatic motors, which leads to bulky devices with slow inflation cycles, uncomfortable sleeves, lack of patient mobility, and ultimately poor patient compliance with therapy. A novel mechanical device for lower leg graded intermittent sequential compression was designed to address these limitations of IPC therapy for venous leg ulcer treatment by providing rapid compression cycles in a truly wearable device that offers the additional benefit of monitoring compression dose and patient compliance. The wearable intermittent compression (WIC) device was hypothesized to provide improved augmentation of venous flow compared with both baseline and standard IPC therapy. METHODS Ten patients with Clinical, Etiologic, Anatomic and Pathophysiologic class 3 to 6 venous insufficiency were recruited under institutional review board approval. The primary end point for the study was augmentation of venous blood flow as measured by peak venous velocity. Patients underwent measurement of peak venous velocity in centimeters per second at the popliteal and femoral veins for the following conditions: (1) baseline, (2) WIC device on a low setting, and (3) WIC device on a high setting. In five patients, an additional measurement of peak venous velocity in centimeters per second at the popliteal and femoral veins was completed while wearing a commercially available IPC device. RESULTS Both low and high settings of the WIC device resulted in higher average peak venous velocities when compared with both baseline and the IPC device (P < .05). No patients reported discomfort with either the WIC device or the IPC device during therapy. CONCLUSIONS The WIC device significantly increases the augmentation of venous flow as measured by peak venous velocity in both the popliteal and femoral veins in patients with Clinical, Etiologic, Anatomic and Pathophysiologic class 3 to 6 venous insufficiency. In addition, the WIC device was found to be easy to use and comfortable during therapy. Future studies are planned to determine if the WIC improvements in venous flow augmentation and patient compliance will lead to higher rates of venous ulcer healing.

Abstract
BACKGROUND Despite regular treatment of venous leg ulcers (VLUs), some fail to heal. Although several risk factors have previously been identified to be associated with the failure of VLUs to heal, the majority of studies are limited to <24-week follow-up. METHODS A retrospective cohort study was performed at an academic vascular and wound center. A total of 65 patients with VLUs who were observed for a year or more were identified. These patients underwent a variety of treatments following the Society for Vascular Surgery and American Venous Forum VLU guidelines. Risk factors, which were based on previously defined elements for failure of VLUs to heal after a period of treatment, were examined. Both univariate (unadjusted) and multivariate (adjusted) logistic regression analyses were used to assess the magnitude of effect that a given risk factor had on healing. RESULTS Of 65 patients treated for a minimum of 52 weeks, 19 (29%) remained unhealed. By univariate analysis, deep venous disease (P = .01; odds ratio [OR], 5.82; 95% confidence interval [CI], 1.49-22.72), history of deep venous thrombosis (P < .001; OR, 14.06; 95% CI, 3.77-52.39), and depression (P = .04; OR, 3.89; 95% CI, 1.10-13.80) were all shown to be significant risk factors for nonhealing. The patient's race (ie, being nonwhite; P = .02; OR, 103.45; 95% CI, 1.94-5.53 × 103), deep venous disease (P = .05; OR, 37.0; 95% CI, 1.05-1.31 × 103), and history of deep venous thrombosis (P = .01; OR, 122.4; 95% CI, 3.09-4.84 × 103), however, were all shown to be significant for nonhealing under multivariate analysis. In addition, identification of an incompetent perforator (P = .02; OR, 0.006; 95% CI, 9.27 × 10-5-0.44) was conversely shown to be a good prognostic factor for healing. CONCLUSIONS This study confirmed that risk factors known to be associated with the failure of a VLU to heal-deep venous disease and post-thrombotic etiology-were significant at 52 weeks, whereas depression and race (nonwhite) are novel risk factors. An analysis of markers of access to care showed no difference between white and nonwhite, suggesting other factors as a cause. The predominance of deep venous disease in the unhealed vs healed cohort (84% vs 48%) highlights the need for a viable treatment option for deep venous disease due to reflux. Overall, this study emphasizes the need to consider all risk factors when evaluating a patient for VLU to coordinate an effective treatment plan and to identify gaps in our treatment.

Abstract
A 57-year-old man with post-thrombotic syndrome presented to the vascular clinic with multiple recurrent nonhealing ulcerations, swelling, and hyperpigmentation of the right lower extremity 30 years after a Palma procedure. On venography, a right to left femoral-femoral Palma bypass graft was noted to be patent, with occlusion of the iliac vein. Endovascular stenting of the right iliac veins led to complete resolution of symptoms and ulcer healing. The bypass and the stents remain patent 4 years after the procedure.

Abstract
BACKGROUND Different methods are available for the treatment of venous ulcers. Most current approaches focus on a combination of topical and compressive therapy. Adjuvant low-level laser therapy may be helpful in lesions with a protracted healing course, but evidence for its use is still limited. This paper describes the protocol of a randomized controlled trial designed to compare the effect of adjuvant low-level laser therapy versus conventional venous ulcer tissue repair, evaluated by a nurse using clinical indicators from the Nursing Outcomes Classification (NOC). METHODS/DESIGN For this prospective randomized controlled trial, 40 adult patients of both sexes with active venous ulcers will be recruited. Subjects will be selected by the sealed-envelope method without any annotation or external identification that might refer to the type of study group. At the time of unblinding, a label with the description of the group to which the patient belongs (that is, control or intervention) will be found inside the envelope. Conventional treatment (topical medication and compressive therapy) will be offered to both groups. Additionally, the intervention group will receive adjuvant low-level laser therapy. All patients will be followed weekly until ulcer healing or for a maximum of 16 weeks. Evaluation of tissue repair will be based on 14 clinical indicators drawn from NOC for wound healing (secondary intention) and tissue integrity (skin and mucous membranes). The primary endpoint will be decreased wound size and scar formation. This laser therapy is expected to enhance the quality, speed, and effectiveness of the treatment of venous ulcers, a chronic condition. This should reduce associated costs to the health service and allow patients to resume their daily activities sooner. DISCUSSION This randomized clinical trial will use a validated method to investigate the effect of a novel intervention for the treatment of venous ulcers.

Abstract
Venous ulcers are a common chronic problem in many countries especially in Northern Europe and USA. The overall prevalence of this condition is 1% rising to 3% in the over 65 years of age. Over the last 25 years, there have been many developments applicable to its diagnosis and treatment. These advances, notwithstanding healing response and recurrence, are variable, and the venous ulcer continues to be a clinical challenge. The pathogenesis of venous ulcers is unrelieved or ambulatory venous hypertension resulting mostly from deep venous thrombosis leading to venous incompetence, lipodermatosclerosis, leucocyte plugging of the capillaries, tissue hypoxia and microvascular dysfunction. It is not known what initiates venous ulcers. Triggers vary from trauma of the lower extremity to scratching to relieve itchy skin over the ankle region. Venous ulcers can be painful, and this condition presents an increasing burden of care. A systematic analysis of the role of technology used for diagnosis and management strongly supports the use of compression as a mainstay of standardised care. It further shows good evidence for the potential of some treatment procedures to accelerate healing. This article reviews the pathogenetic mechanisms, current diagnostic methods and standard care and its limitations.

Abstract
Introduction Compression therapy is well-established standard of care for chronic leg ulcers from venous disease and lymphedema. Chronic leg ulcers and lymphedema have a significant impact on quality of life, driven by pain, foul odor, and restricted mobility. Provision of layered compression therapy in resource-limited settings, as in Western Kenya and other regions of sub-Saharan Africa, is a major challenge due to several barriers: availability, affordability, and access to healthcare facilities. When wound care providers from an Academic Model Providing Access to Healthcare (AMPATH) health center in Western Kenya noted that a donated, finite supply of two-component compression bandages was helping to heal chronic leg ulcers, they began to explore the potential of finding a local, sustainable solution. Dermatology and pharmacy teams from AMPATH collaborated with health center providers to address this need. Methods Following a literature review and examination of ingredients in prepackaged brand-name kits, essential components were identified: elastic crepe, gauze, and zinc oxide paste. All of these materials are locally available and routinely used for wound care. Two-component compression bandages were made by applying zinc oxide to dry gauze for the inner layer and using elastic crepe as the outer layer. Feedback from wound clinic providers was utilized to optimize the compression bandages for ease of use. Results Adjustments to assembly of the paste bandage included use of zinc oxide paste instead of zinc oxide ointment for easier gauze impregnation and cutting the inner layer gauze in half lengthwise to facilitate easier bandaging of the leg, such that there were two rolls of zinc-impregnated gauze each measuring 5 inches × 2 m. Adjustments to use of the compression bandage have included increasing the frequency of bandage changes from 7 to 3 days during the rainy seasons, when it is difficult to keep the bandage dry. Continuous local acquisition of all components led to lower price quotes for bulk materials, driving down the production cost and enabling a cost to the patient of 200 KSh (2 USD) per two-component compression bandage kit. Wound care providers have provided anecdotal reports of healed chronic leg ulcers (from venous stasis, trauma), improved lymphedema, and patient tolerance of compression. Conclusions Low-cost locally sourced two-component compression bandages have been developed for use in Western Kenya. Their use has been initiated at an AMPATH health center and is poised to meet the need for affordable compression therapy options in Western Kenya. Studies evaluating their efficacy in chronic leg ulcers and Kaposi sarcoma lymphedema are ongoing. Future work should address adaptation of compression bandages for optimal use in Western Kenya and evaluate reproducibility of these bandages in similar settings, as well as consider home- or community-based care delivery models to mitigate transportation costs associated with accessing healthcare facilities.

Abstract
Venous ulcer is an extremely common aetiology of lower extremity ulceration, which affects approximately 1% population in most of the countries, and the incidence rate increases with age and female gender. Proper assessment and diagnosis of both the patient and ulcer are inevitable in order to differentiate venous ulcers from other lower extremity ulceration and to frame an adequate and individualised management plan. Venous ulcers generally persist for weeks to many years and are typically recurrent in nature. This consensus aims to present an evidence-based management approach for the patients with venous ulcers. Various management options for venous ulcers include compression therapy, minimally invasive procedures like sclerotherapy and ablation techniques, surgical procedures, debridement and medical management with micronised purified flavonoid fraction (MPFF). Compression therapy is the mainstay treatment for venous ulcer. However, in failure cases, surgery can be preferred. Medical management with MPFF as an adjuvant therapy to standard treatment has been reported to be effective and safe in patients with venous ulcer. In addition to standard therapy, diet and lifestyle modification including progressive resistance exercise, patient education, leg elevation, weight reduction, maintaining a healthy cardiac status and strong psychosocial support reduces the risk of recurrence and improves the quality of life in patients with venous ulcer.

Abstract
The clinical variability and professional uncertainty in the prevention and treatment of lower extremity venous ulcers (VU) has as a main consequence, the fact that patients can be subjected to diagnostic and therapeutic tests, sometimes of dubious utility, these may even be harmful to the health of the patient and that, at other times, certain procedures or processes that may be appropriate to the patient's situation and needs may be omitted. It is for this reason that a series of specific documents called clinical practice guidelines for the approach of VU (CPG-VU) have been created, with the aim of improving the effectiveness and quality of care, reducing unjustified variability and establishing homogeneous criteria for its handling. Nevertheless, the literature shows that not all CPGs have the same methodological and evidence-drawing criteria. Many of them are of poor scientific quality and editorial rigor. This implies that CPGs should be periodically reviewed and updated based on the most current evidence and their quality contrasted with validated instruments such as AGREE-II. After an analysis of the quality of six CPG-VU available today, it has been possible to identify what guidelines are recommended for its implementation in the practice of care, which should be modified to improve their applicability and development of the evidence.

Abstract
Skin grafting is one of the most common surgical procedures in the area of non-healing wounds by which skin or a skin substitute is placed over a wound to replace and regenerate the damaged skin. Chronic leg ulcers are an important problem and a major source of expense for Western countries and for which many different forms of treatment have been used. Skin grafting is a method of treatment that decreases the area of chronic leg ulcers or heals them completely, thus improving a patient's quality of life. Skin grafting is an old technique, rediscovered during the first and second world wars as the main treatment for wound closure. Nowadays, skin grafting has a pivotal role in the context of modern wound healing and tissue regeneration. The aim of this review was to track and to analyse the specific outcomes this technique achieved, especially in the last decade, in relation to venous, arterial, diabetic, rheumatoid and traumatic leg ulcers. Our main findings indicate that autologous split-thickness skin grafting still remains the gold standard in terms of safety and efficacy for chronic leg ulcers; skin grafting procedures have greater success rates in chronic venous leg ulcers compared to other types of chronic leg ulcers; skin tissue engineering, also supported by genetic manipulation, is quickly expanding and, in the near future, may provide even better outcomes in the area of treatments for long-lasting chronic wounds.
