The influence of socioeconomic factors on intervention and postoperative healing of venous ulcers: a prospective study.

OBJECTIVE: In previous studies, venous ulcers (VUs) have been found to occur more often in patients with lower socioeconomic status. The aim of this study was to explore if socioeconomic factors influence the delay of referral to a vascular service or the time to healing after superficial venous intervention. METHOD: In this prospective study, patients answered a questionnaire about the duration and recurrence of their VU, comorbidities, body mass index (BMI), smoking, alcohol, social and physical activities, ambulatory status, education, marital status, housing, perceived economic status and dependence on home care. Postoperative complications, VU healing and recurrence were noted one year after superficial venous intervention. RESULTS: A total of 63 patients were included in this study (30 females and 33 males), with a mean age of 71.2 years (range: 37-92 years). Duration of the present VU in patients was: <3 months in 48%; 3-6 months in 27%; 6-12 months in 11%; and >12 months in 14%. Risk factors for delayed referral were recurrent VU (odds ratio (OR): 4.92; p=0.021); walking impairment (OR: 5.43; p=0.009) and dependence on home care (OR: 4.89: p=0.039) in a univariable analysis. The latter was the only significant finding in a multivariable analysis with socioeconomic risk factor (OR: 4.89; p=0.035). In 85% of patients, their VU healed without recurrence during one year follow-up. Healing took longer if the patients: were of older age (p=0.033); had a normal BMI (independent samples t-test, p=0.028); had a recurrent VU (OR: 5.00; p=0.049); or walking impairment (Fishers exact test, OR: 9.14; p=0.008), but no significant socioeconomic risk factors were found. CONCLUSION: In this study, socioeconomic factors were not important risk factors for delayed referral of VU patients to a vascular service or prolonged healing time after superficial venous intervention.

Diagnosis and treatment of venous leg ulcers: S2k Guideline of the German Society of Phlebology and Lymphology (DGPL) e.V.

This S2k guideline on venous leg ulcers was created on the initiative and under the leadership of the German Society of Phlebology and Lymphology (DGPL). The guideline group also consisted of representatives from the German Society for Phlebology and Lymphology, German Dermatological Society, German Society for General Medicine, German Society for Angiology, German Society for Vascular Surgery and Vascular Medicine, German Society for Surgery, German Society for Dermatosurgery, German Society for Wound Healing and Wound Treatment, Professional Association of Phlebologists and Lymphologists and Initiative Chronische Wunden. The aim of this guideline is to combine the different approaches and levels of knowledge of the respective professional groups on the basis of consensus, so that a basic concept for the best possible treatment of patients with venous leg ulcers can be provided. A total of 70 specific recommendations were formulated and agreed upon, divided into the subject areas of diagnostics, therapy, prevention of recurrences, and everyday challenges. The guideline thus reflects the current state of scientific knowledge and is intended to be widely used as the best available document for the treatment of patients with venous leg ulcers in everyday clinical practice.

Addressing the Impact of Deep Venous Stenting on the Management of Venous Ulcer.

BACKGROUND: Venous ulcers are a late and severe form of chronic venous insufficiency and account for 70% of all etiologies that cause leg ulcers in the lower limb, and they account for 20% of the 2.5 million cases complaining of chronic venous disease. Our study aims to investigate the effect of venous stenting of the deep veins on the healing of the venous ulcer. METHODS: This is a single-center, retrospective study conducted on prospectively recorded medical records of 78 patients with chronic deep venous diseases-C6 (either nonocclusive iliac venous lesion or post-thrombotic syndrome). Our lesion involved May-Thurner lesions, occlusions, insufficiencies, or stenoses owing to an affection of the venous outflow segment. All our patients underwent endovascular management, and those who did not respond successfully were transitioned to compression therapy. We then compared the outcomes of both groups in terms of ulcer healing and quality of life. RESULTS: A total of 78 patients (78 limbs), with a mean age of 39.6 ± 8.06 (range: 22-60) years, were treated. Fifty-four patients (67.9%) were males, and 24 (32.1%) were female. The etiology was primary nonocclusive iliac venous lesion in 12 limbs (16.2%) and secondary post-thrombotic obstructions in 66 (83.7%). Follow-up of the ulcer with compliance to compression therapy and standard care of the ulcer, sustained ulcer healing (reduction in ulcer area) was achieved in 60% of limbs, and most of the nonocclusive healing occurred within the first 3 months (P < 0.01). CONCLUSIONS: Our results show that deep venous stenting is associated with high wound healing rates. This rate reaches a statistically significant difference in 3 months, but this difference doesn't reach statistical significance at 6 months, with less recurrence and improved quality of life with a high cumulative patency rate, and compression therapy is the mainstay of the conservative management of venous ulceration.

Impact of great saphenous vein ablation on healing and recurrence of venous leg ulcers in patients with post-thrombotic syndrome: A retrospective comparative study.

BACKGROUND: The optimal treatment approach for patients with active venous leg ulcers (VLUs) and post-thrombotic syndrome (PTS) associated with great saphenous vein (GSV) reflux remains unclear. To address this gap, we retrospectively compared the outcomes of patients with post-thrombotic VLU with an intact GSV vs those with a stripped or ablated GSV. METHODS: We retrospectively analyzed data from 48 patients with active VLUs and documented PTS, who were treated at a single center between January 2018 and December 2022. Clinical information, including ulcer photographs, was recorded in a prospectively maintained digital database at the initial and follow-up visits. Two patient groups-group A (with an intact GSV) and group B (with a stripped or ablated GSV)-were compared in terms of time to complete healing, proportion of ulcers achieving complete healing, and ulcer recurrence during the follow-up period. RESULTS: There were no significant differences in age, gender, initial ulcer size, or ulcer duration between the two groups. All included patients had femoropopliteal post-thrombotic changes. Group A had significantly more completely healed ulcers (33 of 34 ulcers, 97%) compared with group B (10 of 14 ulcers, 71%) (P = .008). Group A also exhibited a significantly shorter time to complete ulcer healing (median: 42.5 days, interquartile range [IQR]: 65) compared with group B (median: 161 days, IQR: 530.5) (P = .0177), with a greater probability of ulcer healing (P = .0084). Long-term follow-up data were available for 45 of 48 patients (93.7%), with a mean duration of 39.6 months (range: 5.7-67.4 months). The proportion of ulcers that failed to heal or recurred during the follow-up period was significantly lower in group A (9 of 32 ulcers, 27%) compared with group B (11 of 13 ulcers, 85%) (P = .0009). In addition, in a subgroup analysis, patients with an intact but refluxing GSV (12 of 34) had a significantly shorter time to heal (median: 34 days, IQR: 57.25) (P = .0242), with a greater probability of ulcer healing (P = .0091) and significantly fewer recurrences (2 of 12, 16%) (P = .006) compared with group B. CONCLUSIONS: Our findings suggest that removal of the GSV through stripping or ablation in patients with post-thrombotic deep venous systems affecting the femoropopliteal segment may result in delayed ulcer healing and increased ulcer recurrence. Patients with an intact GSV had better outcomes, even when the refluxing GSV was left untreated. These findings emphasize the potential impact of GSV treatment on the management of VLUs in individuals with PTS. Further investigation is needed to validate these results and explore alternative therapeutic strategies to optimize outcomes for this patient population.

Dehydrated human amnion/chorion membrane to treat venous leg ulcers: a cost-effectiveness analysis.

OBJECTIVE: To evaluate the cost-effectiveness of dehydrated human amnion/chorion membrane (DHACM) in Medicare enrolees who developed a venous leg ulcer (VLU). METHOD: This economic evaluation used a four-state Markov model to simulate the disease progression of VLUs for patients receiving advanced treatment (AT) with DHACM or no advanced treatment (NAT) over a three-year time horizon from a US Medicare perspective. DHACM treatments were assessed when following parameters for use (FPFU), whereby applications were initiated 30-45 days after the initial VLU diagnosis claim, and reapplications occurred on a weekly to biweekly basis until completion of the treatment episode. The cohort was modelled on the claims of 530,220 Medicare enrolees who developed a VLU between 2015-2019. Direct medical costs, quality-adjusted life years (QALYs), and the net monetary benefit (NMB) at a willingness-to-pay threshold of $100,000/QALY were applied. Univariate and probabilistic sensitivity analyses (PSA) were performed to test the uncertainty of model results. RESULTS: DHACM applied FPFU dominated NAT, yielding a lower per-patient cost of $170 and an increase of 0.010 QALYs over three years. The resulting NMB was $1178 per patient in favour of DHACM FPFU over the same time horizon. The rate of VLU recurrence had a notable impact on model uncertainty. In the PSA, DHACM FPFU was cost-effective in 63.01% of simulations at the $100,000/QALY threshold. CONCLUSION: In this analysis, DHACM FPFU was the dominant strategy compared to NAT, as it was cost-saving and generated a greater number of QALYs over three years from the US Medicare perspective. A companion VLU Medicare outcomes analysis revealed that patients who received AT with a cellular, acellular and matrix-like product (CAMP) compared to patients who received NAT had the best outcomes. Given the added clinical benefits to patients at lower cost, providers should recommend DHACM FPFU to patients with VLU who qualify. Decision-makers for public insurers (e.g., Medicare and Medicaid) and commercial payers should establish preferential formulary placement for reimbursement of DHACM to reduce budget impact and improve the long-term health of their patient populations dealing with these chronic wounds.

Use of amniotic membrane in hard-to-heal wounds: a multicentre retrospective study.

OBJECTIVE: Hard-to-heal (chronic) wounds negatively impact patients and are a source of significant strain on the healthcare system and economy. These wounds are often resistant to standard of care (SoC) wound healing approaches due to a diversity of underlying pathologies. Cellular, acellular, and matrix-like products, such as amniotic membranes (AM), are a potential solution to these challenges. A growing body of evidence suggests that AM may be useful for treatment-resistant wounds; however, limited information is available regarding the efficacy of dehydrated amniotic membrane (DHAM) on multi-aetiology, hard-to-heal wounds. Therefore, we analysed the efficacy of DHAM treatment in reducing the size of hard-to-heal diabetic and venous leg ulcers (VLUs) that had failed to improve after SoC-based treatments. METHOD: In this multicentre retrospective study, we analysed wound size during clinic visits for patients being treated for either diabetic or VLUs. During each visit, the treatment consisted of debridement followed by application of DHAM. Each wound was measured after debridement and prior to DHAM application, and wound volumes over time or number of DHAM applications were compared. RESULTS: A total of 18 wounds in 11 patients were analysed as part of this study. Wounds showed a significant reduction in volume after a single DHAM application, and a 50% reduction in wound size was observed after approximately two DHAM applications. These findings are consistent with reports investigating DHAM treatment of diabetic ulcers that were not necessarily resistant to treatment. CONCLUSION: To our knowledge, this study is the first to directly compare the efficacy of standalone DHAM application to hard-to-heal diabetic and venous leg ulcers, and our findings indicate that DHAM is an effective intervention for resolving these types of wounds. This suggests that implementing this approach could lead to fewer clinic visits, cost savings and improved patient quality of life.

Healing of Venous Leg Ulcers Influenced by Individual Aspects: Cluster Analysis in a Specialist Wound Management Clinic.

INTRODUCTION/OBJECTIVE: Venous Leg Ulcers (VLU) present a challenging healing process. Attaining healing is a primary treatment objective, commonly pursued in Primary Health Care (PHC) or Specialist Wound Management Clinics. Our objective was to examine the association and interplay between sociodemographic, health, clinical, and care factors with the outcomes of VLU treatment in patients undergoing care at a Specialist Wound Management Clinic. METHODS: Longitudinal, observational study took place in a center for the treatment of chronic injuries linked to PHC. The sociodemographic aspects, health status and habits, clinical and care aspects of patients with VLU were scrutinized over a 1-year period. RESULTS: The sample comprised 103 participants, with some still under treatment (Treatment Group-TG/ n = 60) and others having achieved VLU healing (Healing Group-HG/ n = 43). An association between sociodemographic, health, clinical, and care factors and the healing outcome (HG) was identified. A moderate correlation was observed between factors predisposing to healing in the sociodemographic group and health habits. Notably, among sociodemographic factors, the older age group and improvements in health, particularly the reduced use of alcohol/smoking, appeared to exert the most significant influence on healing. Additionally, specialized service monitoring and the application of compression therapy were contributory factors. CONCLUSIONS: These findings substantiate the hypothesis that sociodemographic, health, clinical, and care-related aspects are intertwined with VLU healing. Protective factors associated with healing interacted synergistically, fostering a positive outcome over one year of treatment.

Prognostic models for clinical outcomes in patients with venous leg ulcers: A systematic review.

OBJECTIVE: The purpose of this review was to identify prognostic models for clinical application in patients with venous leg ulcers (VLUs). METHODS: Literature searches were conducted in Embase, Medline, Cochrane, and CINAHL databases from inception to December 22, 2021. Eligible studies reported prognostic models aimed at developing, validating, and adjusting multivariable prognostic models that include multiple prognostic factors combined, and that predicted clinical outcomes. Methodological quality was assessed using the CHARMS checklist and PROBAST short form questionnaire. RESULTS: Thirteen studies were identified, of which three were validation studies of previously published models, four reported derivation and validation of models, and the remainder reported derivation models only. There was substantial heterogeneity in the model characteristics, including 11 studies focused on wound healing outcomes reporting 91 different predictors. Three studies shared similar predicted outcomes, follow-up timepoint and used a Cox proportional hazards model. However, these models reported different predictor selection methods and different predictors and it was therefore not feasible to summarize performance, such as discriminative ability. CONCLUSIONS: There are no standout risk prediction models in the literature with promising clinical application for patients with VLUs. Future research should focus on developing and validating high-performing models in wider VLU populations.

Testing the feasibility of a co-designed intervention, comprising self-managed, home-based, exercise training with embedded behavioural support and compression therapy for people with venous leg ulcers receiving treatment at home (FISCU-II).

BACKGROUND: Venous leg ulcers (VLUs) heal slowly, are painful for patients and are costly for healthcare systems; they also affect patients' quality of life. Previous work suggests that supervised exercise training used in combination with compression therapy may offer clinical benefits. However, a large population of people with VLUs are unable to access such an intervention due to frailty and age. OBJECTIVES: To assess the feasibility of 'FISCU Home' (a co-designed, 12-week home-based self-managed lifestyle programme based on exercise and behaviour support) as an adjunct therapy to compression in people with VLUs. METHODS: Forty people with VLUs, receiving treatment at home, were recruited from community nursing and tissue viability teams, and via a newspaper advertisement. Participants were randomized 1 : 1 either to exercise with behaviour support (three times per week) plus compression therapy or compression only. The feasibility of the programme was assessed using progression criteria that included exercise attendance rate, loss to follow-up, patient preference(s) and adverse events (AEs). Baseline assessments were repeated at 12 weeks and 6 months. Secondary outcomes (i.e. ulcer recurrence, healing rate and healing time) were also documented at these intervals. Intervention and healthcare utilization costs were calculated. RESULTS: The study recruitment rate was 65%, while 75% of the exercise group participants attended all scheduled exercise sessions. All participants completed compression therapy. No serious AEs or exercise-related AEs were reported. Median (interquartile range) ulcer healing time was shorter in the exercise group [29 (7-108) vs. 42 (6-116) weeks]. CONCLUSIONS: The feasibility and acceptability of both a home- and exercise-based lifestyle intervention in conjunction with compression therapy and the study procedures are supported.

Cost-effectiveness analysis of intralesional and perilesional recombinant human epidermal growth factor vs hydrocolloid therapy in venous ulcer treatment in the Colombian context.

OBJECTIVE: To perform a comparative analysis of health care expenses and outcomes in response to the question: What is the cost-effectiveness of intralesional and perilesional recombinant human epidermal growth factor (rhEGF) compared with hydrocolloid therapy in patients diagnosed with chronic venous insufficiency without infection in Colombia? METHODS: A Markov model was used to determine cost effectiveness over a 5-year period, considering the perspective of the health system in Colombia. The study included patients aged >18 years diagnosed with chronic venous insufficiency and used clinical studies to calculate the probabilities of epithelialization, infection, recurrence, and mortality. RESULTS: RhEGF is more expensive per unit than hydrocolloids, but it is proven to be effective at healing ulcers in 8 to 12 weeks, even in complex cases. Hydrocolloids, in contrast, typically require 29.5 weeks on average, and ≤46 weeks for complex cases. Despite the cost, rhEGF is more cost effective because it achieves results comparable with hydrocolloid therapy at a lower cost per additional quality-adjusted life-year. CONCLUSIONS: Based on cost-effectiveness analysis, rhEGF is a superior alternative to hydrocolloids for treating venous ulcers in Colombia. Not only is it more affordable, but it also enhances patients' quality of life and streamlines the health care system's resource use.

Diagnosing and Managing Venous Stasis Disease and Leg Ulcers.

Venous insufficiency is a common medical condition that affects many individuals, especially those with advanced age. Chronic venous insufficiency can lead to secondary cutaneous changes that most commonly present as stasis dermatitis but can progress to more serious venous ulcers. Although venous ulcers are the most common cause of lower extremity ulcers, the differential diagnosis of leg ulcers is broad. This article will discuss clinical clues to help guide patient workup and will review basic clinical evaluation and management of common leg ulcers.

Análisis costo-efectividad del tratamiento con terapia compresiva en la cicatrización de úlceras venosas / Cost-effectiveness analysis of the treatment with compressive therapy in the healing of venous ulcers / Análise de custo-efetividade do tratamento com terapia compressiva na cicatrização de úlceras venosas

Objetivo: analizar el costo-efectividad y calcular la relación costoefectividad incremental del tratamiento multicapa compresivo con respecto al inelástico (bota de Unna y estiramiento corto) según la literatura actual. Método: estudio cuantitativo de costo-efectividad a través de un modelo con ayuda del software TreeAge® para la elaboración del árbol de decisión. Los supuestos anunciados se obtuvieron mediante el uso de datos secundarios de la literatura para estimar el costo y la efectividad de los parámetros asumidos. Para ello, se realizó una revisión sistemática de la literatura con metaanálisis. Resultados: el árbol de decisión, después del Roll Back, mostró que la terapia multicapa prevaleció sobre las alternativas en el caso base, presentó un costo intermedio por aplicación, pero obtuvo la mayor efectividad. El gráfico del análisis de costo-efectividad también demostró que había un dominio extendido de la bota de Unna sobre el vendaje de estiramiento corto. El análisis de sensibilidad reveló que el vendaje multicapa sigue siendo la alternativa con mayor costoefectividad, dentro del umbral de disposición a pagar. Conclusión: la alternativa con mayor costo-efectividad fue el vendaje multicapa, considerado estándar de oro en la literatura. La segunda alternativa con mayor costo-efectividad fue la bota de Unna, la terapia más utilizada en Brasil.

Objective: to analyze the cost-effectiveness and calculate the incremental cost-effectiveness ratio of multilayer compressive treatment in relation to inelastic (Unna boot and short stretch) therapy according to the current literature. Method: quantitative study about cost-effectiveness through modeling with the aid of TreeAge® software for construction of the decision tree. The anticipated assumptions were obtained by using secondary literature data to estimate the cost and effectiveness of the assumed parameters. A systematic literature review with meta-analysis was performed for this end. Results: the decision tree after Roll Back showed that the multilayer therapy dominated the alternatives in the base case, representing an intermediate cost per application, although with the highest effectiveness. The cost-effectiveness analysis graph also showed extended dominance of the Unna boot in relation to the short stretch bandage. The sensitivity analysis showed that multilayer bandage remains a more cost-effective alternative, within the threshold of willingness to pay. Conclusion: the most cost-effective alternative was multilayer bandage, considered the gold standard in the literature. The second most cost-effective alternative was the Unna boot, the most used therapy in Brazil.

Aquacel Ag Advantage/Ag+ Extra and Cutimed Sorbact in the management of hard-to-heal wounds: a cohort study.

OBJECTIVE: To compare Aquacel Ag Advantage/Ag+ Extra (Aquacel Ag+) (Convatec, UK) and Cutimed Sorbact (Sorbact) (Essity, US) dressings indicated for the treatment of patients with venous leg ulcers (VLUs), diabetes foot ulcers (DFUs) and pressure injuries (PIs) for clinical performance and outcomes using real-world evidence in Germany and the US. METHOD: This study was a chart audit review of patients who used either Aquacel Ag+ or Sorbact dressings in the 24 months prior to October 2022. Healthcare providers with access to electronic medical records and charts were asked to capture data via patient record forms. The quantitative data were analysed. RESULTS: Findings in Germany were comparable between Aquacel Ag+ and Sorbact with regards to wound description, management and treatment outcomes, including percent area reduction and wound closure. A difference was that a greater proportion of Sorbact patients required surgery (0% versus 11%; p=0.039). In the US, a greater proportion of wounds were worsening before dressing in the Aquacel Ag+ cohort (49% versus 34%; p=0.010). A multinomial logistic regression yielded the result that patients who received Aquacel Ag+ were 3.53 times more likely to have the wound completely healed (p=0.033). CONCLUSION: Both Aquacel Ag+ and Sorbact dressings are widely used in Germany and the US for patients with VLUs, DFUs and PIs. Our study found two important differences: patients who used Aquacel Ag+ were less likely to need further surgery in Germany; and in the US, there were significantly higher odds that wounds would completely heal with Aquacel Ag+ dressings compared to Sorbact.

Nutritional Status of People with a Coexisting Chronic Wound and Extended Assessment Using Bioelectrical Impedance.

The diagnosis of malnutrition should be one of the pillars of comprehensive patient care, especially in the case of patients with large wounds, prolonged healing, or comorbidities. The condition for a reliable and accurate nutritional diagnosis is to link it with the parameters of nutritional status assessment at the basic level (anthropometric measurements and clinical assessment) and in depth (biochemical tests and bioelectrical impedance). A prospective study included a sample of 60 patients with coexisting chronic wounds (venous ulcers, diabetic foot syndrome, pressure injury) treated at the Wound Treatment Clinic of Fr. B. Markiewicz Podkarpackie Oncology Center (Poland). The method of estimation and diagnostic survey was used; the research tool was a scientific research protocol consisting of four parts. Self-care capacity was assessed based on the Barthel scale, nutritional status using blood biochemical parameters, and electrical bioimpedance. Wounds were classified according to the extent, depth of tissue structures, and potential infection. Subjects with pressure ulcers had statistically significantly lower fat-free mass component indices compared to those with diabetic foot syndrome and venous ulceration. The subjects with pressure ulcers had significantly lower values of body composition components compared to those with diabetic foot syndrome and venous ulcers. In the group of patients with pressure ulcers, the lowest values of albumin (3.20 g/dL), hemoglobin (10.81 g/dL), and nutritional risk index (NRI) (88.13 pts.) scores were confirmed. Subjects with pressure ulcers with limited self-care presented a non-physiological nutritional status, indicating a risk of malnutrition. Local actions related to wound treatment should be preceded by a general examination, considering the state of augmented nutrition with the use of electrical bioimpedance.

Endovenous ablation for venous leg ulcers.

BACKGROUND: Venous leg ulcers (VLUs) are a serious manifestation of chronic venous disease affecting up to 3% of the adult population. This typically recalcitrant and recurring condition significantly impairs quality of life, and its treatment places a heavy financial burden upon healthcare systems. The longstanding mainstay treatment for VLUs is compression therapy. Surgical removal of incompetent veins reduces the risk of ulcer recurrence. However, open surgery is an unpopular option amongst people with VLU, and many people are unsuitable for it. The efficacy of the newer, minimally-invasive endovenous techniques has been established in uncomplicated superficial venous disease, and these techniques can also be used in the management of VLU. When used with compression, endovenous ablation aims to further reduce pressure in the veins of the leg, which may impact ulcer healing. OBJECTIVES: To determine the effects of superficial endovenous ablation on the healing and recurrence of venous leg ulcers and the quality of life of people with venous ulcer disease. SEARCH METHODS: In April 2022 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scrutinised reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions on the language of publication, but there was a restriction on publication year from 1998 to April 2022 as superficial endovenous ablation is a comparatively new technology. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing endovenous ablative techniques with compression versus compression therapy alone for the treatment of VLU were eligible for inclusion. Studies needed to have assessed at least one of the following primary review outcomes related to objective measures of ulcer healing such as: proportion of ulcers healed at a given time point; time to complete healing; change in ulcer size; proportion of ulcers recurring over a given time period or at a specific point; or ulcer-free days. Secondary outcomes of interest were patient-reported quality of life, economic data and adverse events. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed studies for eligibility, extracted data, carried out risk of bias assessment using the Cochrane RoB 1 tool, and assessed GRADE certainty of evidence. MAIN RESULTS: The previous version of this review found no RCTs meeting the inclusion criteria. In this update, we identified two eligible RCTs and included them in a meta-analysis. There was a total of 506 participants with an active VLU, with mean durations of 3.1 months ± 1.1 months in the EVRA trial and 60.5 months ± 96.4 months in the VUERT trial. Both trials randomised participants to endovenous treatment and compression or compression alone, however the compression alone group in the EVRA trial received deferred endovenous treatment (after ulcer healing or from six months). There is high-certainty evidence that combined endovenous ablation and compression compared with compression therapy alone, or compression with deferred endovenous treatment, improves time to complete ulcer healing (pooled hazard ratio (HR) 1.41, 95% CI 1.36 to 1.47; I2 = 0%; 2 studies, 466 participants). There is moderate-certainty evidence that the proportion of ulcers healed at 90 days is probably higher with combined endovenous ablation and compression compared with compression therapy alone or compression with deferred endovenous treatment (risk ratio (RR) 1.14, 95% CI 1.00 to 1.30; I2 = 0%; 2 studies, 466 participants). There is low-certainty evidence showing an unclear effect on ulcer recurrence at one year in people with healed ulcers with combined endovenous treatment and compression when compared with compression alone or compression with deferred endovenous treatment (RR 0.29, 95% CI 0.03 to 2.48; I2 = 78%; 2 studies, 460 participants). There is also low-certainty evidence that the median number of ulcer-free days at one year may not differ (306 (interquartile range (IQR) 240 to 328) days versus 278 (IQR 175 to 324) days) following combined endovenous treatment and compression when compared with compression and deferred endovenous treatment; (1 study, 450 participants). There is low-certainty evidence of an unclear effect in rates of thromboembolism between groups (RR 2.02, 95% CI 0.51 to 7.97; I2 = 78%, 2 studies, 506 participants). The addition of endovenous ablation to compression is probably cost-effective at one year (99% probability at GBP 20,000/QALY; 1 study; moderate-certainty evidence). AUTHORS' CONCLUSIONS: Endovenous ablation of superficial venous incompetence in combination with compression improves leg ulcer healing when compared with compression alone. This conclusion is based on high-certainty evidence. There is moderate-certainty evidence to suggest that it is probably cost-effective at one year and low certainty evidence of unclear effects on recurrence and complications. Further research is needed to explore the additional benefit of endovenous ablation in ulcers of greater than six months duration and the optimal modality of endovenous ablation.

A New Powder Dressing for Management of Chronic Venous Ulcers.

BACKGROUND: A new powder dressing (TPD) is a methacrylate-based powder formulation that transforms in situ into a shape-retentive matrix upon hydration to create optimum moist wound healing conditions. The following randomized, controlled, clinical study aimed to evaluate the role of TPD in the management of chronic venous ulcers (CVU). METHODS: The randomized controlled prospective study enrolled 60 CVU patients. After randomization, patients in the treatment group ( n = 30) were treated with TPD, whereas those in the control group ( n = 30) received conventional compression dressing therapy. RESULTS: After treatment, patients in the TPD group had significantly higher rates of complete ulcer healing at 12 weeks (43.3% vs 10.0%, p = .004) and 24 weeks (86.7% vs 40.0%, p = .001) when compared with conventional dressing group. Moreover, patients in the TP dressing group had significantly shorter time to complete ulcer healing [mean (95% CI): 16.7 (14.1-19.3) versus 37.0 (30.8-43.2) weeks, p = .001]. In addition, patients in the TPD group had significantly fewer number of dressings, less severe pain after dressing, and lower need for systemic analgesics. CONCLUSION: Use of TPD in management of CVUs was associated with significantly higher healing rates, shorter duration to healing, and lower pain.
