    Abstract 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 We also searched clinical trials registries for ongoing and unpublished studies, and scrutinised reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional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; I
    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.

    Abstract Background: International guidelines recommend postprocedural compression when treating symptomatic superficial venous incompetence (SVI). This updated review of RCTs investigated the requirement for postprocedural compression and how it can be applied optimally.
    Methods: The National Institute for Health and Care Excellence's Healthcare Databases Advanced Search engine was used to identify all English-language RCTs of compression following treatment for SVI. Outcomes of interest included postprocedural pain, venous thromboembolism, health-related quality of life (HRQoL), and anatomical occlusion.
    Results: A total of 18 studies were included comprising some 2584 treated limbs. Compression was compared with no compression in four studies, nine studies compared different durations of compression, and a further five compared different types of compression. A 1-2-week period of compression was associated with a mean reduction of 11 (95 per cent c.i. 8 to 13) points in pain score on a 100-mm visual analogue scale compared with a shorter duration (P < 0.001). This was associated with improved HRQoL and patient satisfaction. Longer durations of compression did not add further benefit. There was low-quality evidence suggesting that 35-mmHg compression with eccentric thigh compression achieved lower pain scores than lower interface pressures. There were no significant differences in venous thromboembolism rates or technical success in any group, including no compression.
    Conclusion: Postprocedural compression of 1-2 weeks after SVI treatment is associated with reduced pain compared with a shorter duration. The optimal interface pressure and type of compression, and the impact on venous thromboembolism risk, remain to be determined.

    Abstract Background: Standardization of access to treatment and compliance with clinical guidelines are important to ensure the delivery of high-quality care to people with varicose veins. In the National Health Service (NHS) in England, commissioning of care for people with varicose veins is performed by Clinical Commissioning Groups (CCGs) and clinical guidelines have been developed by the National Institute for Health and Care Excellence (NICE CG168). The Evidence-Based Intervention (EBI) programme was introduced in the NHS with the aim of improving care quality and supporting implementation of NICE CG168. The aim of this study was to assess access to varicose vein treatments in the NHS and the impact of EBI.
    Methods: CCG policies for the delivery of varicose vein treatments in the NHS in England were obtained from 2017 (before EBI introduction) and 2019 (after EBI introduction) and categorized by two independent reviewers into levels of compliance with NICE CG168. Hospital Episode Statistics data were compared with the NICE commissioning model predictions. A quality-adjusted life-year was valued at £20 000 (Euro 23 000 15 November 2022).
    Results: Despite the introduction of the EBI programme, CCG compliance with NICE CG168 fell from 34.0 per cent (64 of 191) to 29.0 per cent (55 of 191). Some 33.0 per cent of CCG policies (63 of 191) became less compliant and only 7.3 per cent (14 of 191) changed to become fully compliant. Overall, 66.5 per cent of CCGs (127 of 191) provided less than the recommended intervention rate before EBI and this increased to 73.3 per cent (140 of191) after EBI. The overall proportion of patients estimated to require treatment annually who received treatment fell from 44.0 to 37.0 per cent. The associated estimated loss in net health benefit was between £164 and 174 million (Euro 188 million and 199 million 15 November 2022) over 3 years. A compliant policy was associated with a higher intervention rate; however, commissioning policy was associated with only 16.8 per cent of the variation in intervention rate (R2 = 0.168, P < 0.001).
    Conclusion: Many local varicose vein commissioning policies in the NHS are not compliant with NICE CG168. More than half of patients who should be offered varicose vein treatment are not receiving it, and there is widespread geographical variation. The EBI programme has not been associated with any improvement in commissioning or access to varicose vein treatment.

    Abstract Background: Mechanochemical ablation (MOCA) is an alternative method to endovenous thermal ablation (EVTA) for the treatment of superficial venous incompetence that does not require tumescent anaesthesia. The aim of this study was to compare the outcomes from RCTs of MOCA versus EVTA.
    Methods: A search was conducted in MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL). Meta-analysis inclusion was restricted to RCTs comparing MOCA against EVTA. Outcomes included anatomical occlusion rate, disease-specific quality of life using the Aberdeen Varicose Vein Questionnaire, procedural and postprocedural pain, and rates of venous thromboembolism.
    Results: Four RCTs were included in the meta-analysis comprising 654 patients. The anatomical occlusion rate at 1 year was lower after MOCA than EVTA (risk ratio 0.85, 95 per cent c.i. 0.78 to 0.91; P < 0.001). No significant differences were detected in procedural pain (mean difference -3.25, -14.25 to 7.74; P = 0.560) or postprocedural pain (mean difference -0.63, -2.15 to 0.89; P = 0.420). There were no significant differences in Aberdeen Varicose Vein Questionnaire score at 1 year (mean difference 0.06, -0.50 to 0.62; P = 0.830) or in incidence of venous thromboembolism (risk ratio 0.72, 95 per cent c.i. 0.14 to 3.61; P = 0.690).
    Conclusion: The rate of successful anatomical occlusion after MOCA is significantly lower than that after EVTA, but there is no difference in procedural and postprocedural pain between the two interventions. Long-term data are required to assess the impact of the reduced vein occlusion rate on clinical outcomes such as quality of life and reintervention.

    Abstract Objective: This RCT compares the clinical, technical and quality of life outcomes after EVLA and MOCA.
    Summary of background data: Thermal ablation is the current mainstay treatment for SVI. Newer nonthermal methods of treatment have been developed which do not require the use of tumescent anesthesia. The potential advantages of these newer methods should be tested in RCTs to ascertain their role in the future treatments of SVI.
    Methods: This single-center RCT enrolled patients with symptomatic, unilateral, single-axis SVI. Eligible patients were equally randomized to either EVLA or MOCA, both with concomitant phlebectomy when necessary. The joint primary outcomes were intraprocedural axial ablation pain scores and anatomical occlusion at 1 year. Secondary outcomes included postprocedural pain, venous clinical severity score (VCSS), quality of life (Aberdeen varicose veins questionnaire and EuroQol 5-domain utility index), patient satisfaction and complication rates.
    Results: One hundred fifty patients were randomized equally between the 2 interventions. Both groups reported low intraprocedural pain scores; on a 100 mm visual analog scale, pain during axial EVLA was 22 (9-44) compared to 15 (9-29) during MOCA; P = 0.210. At 1 year, duplex derived anatomical occlusion rates after EVLA were 63/69 (91%) compared to 53/69 (77%) in the MOCA group; P = 0.020. Both groups experienced significant improvement in VCSS and AVVQ after treatment, without a significant difference between groups. Median VCSS improved from 6 (5-8) to 0 (0-1) at one year; P < 0.001. Median AVVQ improved from 13.8 (10.0-17.7) to 2.0 (0.0-4.9); P < 0.001. One patient in the MOCA group experienced DVT.
    Conclusions: Both EVLA and MOCA were highly efficacious in treating SVI; patients improved significantly in terms of disease severity, symptoms, and QoL. Both resulted in low procedural pain with a short recovery time. Axial occlusion rates were higher after EVLA. Long term follow-up is warranted to assess the effect of recanalization on the rate of clinical recurrence.
