Abstract
OBJECTIVE The Bypass versus Angioplasty in Severe Ischaemia of the Leg-2 (BASIL-2) randomised controlled trial has shown that, for patients with chronic limb threatening ischaemia (CLTI) who require an infrapopliteal (IP) revascularisation a vein bypass (VB) first revascularisation strategy led to a 35% increased risk of major amputation or death when compared with a best endovascular treatment (BET) first revascularisation strategy. The study aims are to place the BASIL-2 trial within the context of the CLTI patient population as a whole and to investigate the generalisability of the BASIL-2 outcome data. METHODS This was an observational, single centre prospective cohort study. Between 24 June 2014 and 31 July 2018, the BASIL Prospective Cohort Study (PCS) was performed which used BASIL-2 trial case record forms to document the characteristics, initial and subsequent management, and outcomes of 471 consecutive CLTI patients admitted to an academic vascular centre. Ethical approval was obtained, and all patients provided fully informed written consent. Follow up data were censored on 14 December 2022. RESULTS Of the 238 patients who required an infrainguinal revascularisation, 75 (32%) had either IP bypass (39 patients) or IP BET (36 patients) outside BASIL-2. Seventeen patients were initially randomised to BASIL-2. A further three patients who did not have an IP revascularisation as their initial management were later randomised in BASIL-2. Therefore, 95/471 (20%) of patients had IP revascularisation (16% outside, 4% inside BASIL-2). Differences in amputation free survival, overall survival, and limb salvage between IP bypass and IP BET performed outside BASIL-2 were not subject to hypothesis testing due to the small sample size. Reasons for non-randomisation into the trial were numerous, but often due to anatomical and technical considerations. CONCLUSION CLTI patients who required an IP revascularisation procedure and were subsequently randomised into BASIL-2 accounted for a small subset of the CLTI population as a whole. For a wide range of patient, limb, anatomical and operational reasons, most patients in this cohort were deemed unsuitable for randomisation in BASIL-2. The results of BASIL-2 should be interpreted in this context.

Abstract
BACKGROUND Venous leg ulcer (VLU) disease constitutes the most severe form of chronic venous insufficiency. We performed a network meta-analysis and meta-regression to investigate the efficacy and safety of the various available interventions in the treatment of VLU. METHODS We conducted a systematic research corresponding to the instructions by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement for studies reporting on surgical or endovenous interventions for the treatment of VLU. Following data extraction, we performed a Bayesian network meta-analysis and meta-regression. Primary endpoints included VLU healing and recurrence. The secondary endpoint was postintervention complications. RESULTS Seventeen studies evaluating the impact of compression monotherapy, radiofrequency ablation (RFA), endovenous laser ablation (EVLA), sclerotherapy, and saphenous vein surgery on VLU treatment, consisting of 2156 patients (2186 VLU) were included. When compared to compression monotherapy, RFA was the only treatment displaying a statistically-significant impact on ulcer healing, odds ratio (OR) 5.80 (95% credibility interval (CI): 1.08-35.07), while EVLA, RR 0.06 (95% CI: 0.00-0.57), sclerotherapy, RR 0.07 (95% CI: 0.00-0.68) and RFA, RR 0.12 (95% CI: 0.01-0.91) were the 3 interventions reducing VLU recurrence. EVLA (SUCRA, 69.65) ranked as the most efficient intervention concerning ulcer recurrence reduction. Regarding postintervention complications, EVLA was the only intervention displaying a statistically-significant increased risk compared to compression monotherapy, RR 14.3 (95% CI: 2.03-172.56). Meta-regression analysis exploring the impact of perforator treatment on VLU failed to predict healing, β = -0.27 (95% CI: -2.55 to 1.85), recurrence, β = -0.02 (95% CI: -2.96 to 2.75) and complication outcomes, β = -0.089 (95% CI: -3.13 to 2.85). During sensitivity analysis, RFA and sclerotherapy failed to sustain their effects on ulcer healing and ulcer recurrence, respectively. In addition, sclerotherapy displayed statistically-significant inferior outcomes compared to both EVLA and RFA regarding ulcer recurrence. CONCLUSION This is the first network meta-analysis examining the effect of various interventions on VLU disease. While we have demonstrated the efficacy of RFA and ELVA in ulcer recurrence prevention, our results regarding the impact of RFA and sclerotherapy on VLU healing and recurrence, respectively, should be interpreted with caution. In addition, this review raises questions concerning the value of surgery and perforator interventions in the treatment of VLU. Further research through randomized controlled trials is required. CLINICAL IMPACT Our review has revealed the significant efficacy of endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) in effectively reducing the incidence of ulcer recurrence when compared to compression monotherapy. These outcomes hold the potential to provide relevant insights to both medical practitioners and patients, thereby informing a more prudent and enlightened decision-making approach. Such informed decisions, aimed at mitigating the recurring occurrence of venous leg ulcers, carry profound significance given the considerable socioeconomic implications associated with this medical condition.

Abstract
BACKGROUND Chronic limb-threatening ischaemia is the severest manifestation of peripheral arterial disease and presents with ischaemic pain at rest or tissue loss (ulceration, gangrene, or both), or both. We compared the effectiveness of a vein bypass first with a best endovascular treatment first revascularisation strategy in terms of preventing major amputation and death in patients with chronic limb threatening ischaemia who required an infra-popliteal, with or without an additional more proximal infra-inguinal, revascularisation procedure to restore limb perfusion. METHODS Bypass versus Angioplasty for Severe Ischaemia of the Leg (BASIL)-2 was an open-label, pragmatic, multicentre, phase 3, randomised trial done at 41 vascular surgery units in the UK (n=39), Sweden (n=1), and Denmark (n=1). Eligible patients were those who presented to hospital-based vascular surgery units with chronic limb-threatening ischaemia due to atherosclerotic disease and who required an infra-popliteal, with or without an additional more proximal infra-inguinal, revascularisation procedure to restore limb perfusion. Participants were randomly assigned (1:1) to receive either vein bypass (vein bypass group) or best endovascular treatment (best endovascular treatment group) as their first revascularisation procedure through a secure online randomisation system. Participants were excluded if they had ischaemic pain or tissue loss considered not to be primarily due to atherosclerotic peripheral artery disease. Most vein bypasses used the great saphenous vein and originated from the common or superficial femoral arteries. Most endovascular interventions comprised plain balloon angioplasty with selective use of plain or drug eluting stents. Participants were followed up for a minimum of 2 years. Data were collected locally at participating centres. In England, Wales, and Sweden, centralised databases were used to collect information on amputations and deaths. Data were analysed centrally at the Birmingham Clinical Trials Unit. The primary outcome was amputation-free survival defined as time to first major (above the ankle) amputation or death from any cause measured in the intention-to-treat population. Safety was assessed by monitoring serious adverse events up to 30-days after first revascularisation. The trial is registered with the ISRCTN registry, ISRCTN27728689. FINDINGS Between July 22, 2014, and Nov 30, 2020, 345 participants (65 [19%] women and 280 [81%] men; median age 72·5 years [62·7-79·3]) with chronic limb-threatening ischaemia were enrolled in the trial and randomly assigned: 172 (50%) to the vein bypass group and 173 (50%) to the best endovascular treatment group. Major amputation or death occurred in 108 (63%) of 172 patients in the vein bypass group and 92 (53%) of 173 patients in the best endovascular treatment group (adjusted hazard ratio [HR] 1·35 [95% CI 1·02-1·80]; p=0·037). 91 (53%) of 172 patients in the vein bypass group and 77 (45%) of 173 patients in the best endovascular treatment group died (adjusted HR 1·37 [95% CI 1·00-1·87]). In both groups the most common causes of morbidity and death, including that occurring within 30 days of their first revascularisation, were cardiovascular (61 deaths in the vein bypass group and 49 in the best endovascular treatment group) and respiratory events (25 deaths in the vein bypass group and 23 in the best endovascular treatment group; number of cardiovascular and respiratory deaths were not mutually exclusive). INTERPRETATION In the BASIL-2 trial, a best endovascular treatment first revascularisation strategy was associated with a better amputation-free survival, which was largely driven by fewer deaths in the best endovascular treatment group. These data suggest that more patients with chronic limb-threatening ischaemia who required an infra-popliteal, with or without an additional more proximal infra-inguinal, revascularisation procedure to restore limb perfusion should be considered for a best endovascular treatment first revascularisation strategy.

Abstract
The diagnosis of peripheral arterial disease (PAD) is not always evident as symptoms and signs may show great variation. As all grades of PAD are linked to both an increased risk for cardiovascular complications and adverse limb events, awareness of the condition and knowledge about diagnostic measures, prevention and treatment is crucial. This article presents in a condensed form information on PAD and its management.

Abstract
BACKGROUND The Global Limb Anatomic Staging System (GLASS) is a new method of quantifying the anatomic severity of infrainguinal disease in patients with chronic limb-threatening ischemia. However, because GLASS has undergone limited validation, its value as an aid to shared decision-making regarding the choice of revascularization strategy remains incompletely defined. Here we report the relationship between GLASS and outcomes in a contemporary series comprising all 309 patients who underwent an attempt at femoropopliteal and/or infrapopiteal endovascular therapy for chronic limb-threatening ischemia in our unit between 2009 and 2014. METHODS Baseline patient characteristics and outcome data including immediate technical success (ITS), amputation-free survival (AFS), overall survival, limb salvage, freedom from reintervention (FF-R), and freedom from major adverse limb events (FF-MALE) were obtained from hospital databases. GLASS grades and stage were obtained from pre-endovascular therapy angiographic imaging. Outcome data were censored on May 31, 2017. RESULTS Baseline patient characteristics were similar across different GLASS femoropopliteal and IP grades and overall limb stages. Worsening GLASS stage was associated with a significant reduction in ITS (97.5% vs 91.5% vs 84.0%; P = .029). At 72 months FF-R (hazard ratio, 2.00; 95% confidence interval, 1.11-3.57; P = .020) and FF-MALE (hazard ratio, 1.76, 95% confidence interval, 1.10-2.81; P = .019) were significant worse in GLASS stage 3 than in stage 2 limbs. CONCLUSIONS In our study, there were significant differences in ITS, FF-R and FF-MALE between limbs with GLASS stage 2 and 3 disease. However, further GLASS refinement seems likely to be required if its usefulness in everyday clinical practice as an aid to shared decision-making regarding the choice of revascularization strategy is to be maximized.

Abstract
BACKGROUND Ultrasound guided foam sclerotherapy (UGFS) is a flexible and highly utilised tool in the treatment of varicose veins (VVs), both as a primary treatment and as an adjunct to other treatments. Concern remains regarding the risk of neurological adverse events (AEs) such as migraine, visual disturbance and serious adverse events (SAEs) such as cerebrovascular accident that have been reported after UGFS treatments. AIM To determine the incidence of neurological AEs and SAEs after UGFS. METHODS A prospective, multicentre, post-authorisation safety study across Europe (both private and government) was performed between January 2015-2020. Neurological adverse events after UGFS with Fibrovein® (Sodium Tetradecyl Sulfate) 1 and 3% physician generated foam. RESULTS 8056 patients underwent treatment. There were 46 AE (including 5 SAEs), 30 (65%) SAEs were in female patients. Mean age was 55 years with mean body mass index (BMI) of 27. Univariable logistic regression demonstrate that UGFS only treatment (i.e. no adjunctive treatment), liquid-to-gas ratio, gas type and total foam volume (1% sodium tetradecyl sulfate, STS) were significantly associated with the odds of experiencing the outcome. Multivariable logistic regression model exhibits that migraine and total foam volume (1% STS) maintained statistical significance thus associated with the odds of adverse events. CONCLUSIONS This study demonstrates that UGFS with Fibrovein is safe with a very low incidence of neurological AEs and SAEs. Past history of migraine, use of physiological gas (O2/CO2) and increasing volumes of 1% foam increase the risk of AEs.

Abstract
OBJECTIVE Chronic limb-threatening ischemia (CLTI) is a growing global problem due to the widespread use of tobacco and increasing prevalence of diabetes. Although the financial consequences are considerable, few studies have compared the relative cost-effectiveness of different CLTI management strategies. The Bypass vs Angioplasty in Severe Ischaemia of the Leg (BASIL)-2 trial is randomizing patients with CLTI to primary infra-popliteal (IP) vein bypass surgery (BS) or best endovascular treatment (BET) and includes a comprehensive within-trial cost-utility analysis. The aim of this study is to compare over a 12-month time horizon, the costs of primary IP BS, IP best endovascular treatment (BET), and major limb major amputation (MLLA) to inform the BASIL-2 cost-utility analysis. METHODS We compared procedural human resource (HR) costs and total in-hospital costs for the index admission, and over the following 12-months, in 60 consecutive patients undergoing primary IP BS (n = 20), IP BET (n = 20), or MLLA (10 transfemoral and 10 transtibial) for CLTI within the BASIL prospective cohort study. RESULTS Procedural HR costs were greatest for BS (BS £2551; 95% confidence interval [CI], £1934-£2807 vs MLLA £1130; 95% CI, £1046-£1297 vs BET £329; 95% CI, £242-£390; P < .001, Kruskal-Wallis) due to longer procedure duration and greater staff requirement. With regard to the index admission, MLLA was the most expensive due to longer hospital stay (MLLA £13,320; 95% CI, £8986-£18,616 vs BS £8714; 95% CI, £6097-£11,973 vs BET £4813; 95% CI, £3529-£6097; P < .001, Kruskal-Wallis). The total cost of the index admission and in-hospital care over the following 12 months remained least for BET (MLLA £26,327; 95% CI, £17,653-£30,458 vs BS £20,401; 95% CI, £12,071-£23,926 vs BET £12,298; 95% CI, £6961-£15,439; P < .001, Kruskal-Wallis). CONCLUSIONS Over a 12-month time horizon, MLLA and IP BS are more expensive than IP BET in terms of procedural HR costs and total in-hospital costs. These economic data, together with quality of life data from BASIL-2, will inform the calculation of incremental cost-effectiveness ratios for different CLTI management strategies within the BASIL-2 cost-utility analysis.

Abstract
BACKGROUND Since the turn of the millennium there has been a world-wide trend towards an endovascular first where possible revascularisation strategy for chronic limb threatening (CLTI). There is concern that this may be inappropriate and can result in net patient harm. The aim of this study, therefore, is to compare important clinical outcomes following femoro-popliteal plain balloon angioplasty (FP-PBA), with selective use of bare metal stents (BMS), in a contemporary series (CS) of patients treated in our unit between 2009 and 2014 with those observed following FP-PBA +/- BMS in the UK NIHR HTA-funded Bypass versus Angioplasty in Severe Ischaemia of the Leg (BASIL-1, B1) trial (treated 1999-2004). METHODS Baseline and clinical outcome data (amputation free survival, AFS; overall survival, OS; limb salvage, LS; freedom from re-intervention, FF-R; freedom from major adverse limb events, FF-MALE) were obtained from prospectively gathered hospital data and B1 trial case record forms. RESULTS There were 237 CS and 218 B1 patients. CS patients were older (77 vs 73 years, p=.0002). B1 patients were more likely to be current smokers, less likely to be on best medical therapy, and underwent more extensive endovascular interventions. CS had more hospital admissions (4 vs 2, p<.0001) before they reached their primary endpoint (AFS). Immediate technical success was non-significantly higher in the CS patients (87% vs 83%, p=0.2). BMS were used in 20 (8%) CS and 2 (1%) B1 patients (p=.0002). AFS (HR = 0.64, 95%CI: 0.49 to 0.82, p = .0005) and OS (HR = 0.58, 95% CI: 0.44 to 0.76, p = .0001) were significantly worse in the CS cohort. There was no significant difference in LS, FF-R or FF-MALE. CONCLUSIONS CLTI patients managed in our unit (2009-2014) by means of a FP-PBA +/- BMS first where possible revascularisation strategy experience significantly worse AFS and OS than patients treated with FP-PBA +/- BMS in the B1 trial ten years earlier (1999-2004).

Abstract
INTRODUCTION Despite the BASIL-1 trial concluding that bypass surgery (BS) was superior to plain balloon angioplasty (PBA) in terms of longer-term amputation free (AFS) and overall survival (OS), CLTI patients are increasingly offered an endovascular-first revascularization strategy. This study investigates whether the results of BASIL-1 are still relevant to current practice by comparing femoro-popliteal (FP) BS with PBA in a series of CLTI patients treated in our unit 10 years after BASIL-1 (1999-2004). METHODS We retrospectively analyzed prospectively gathered hospital data pertaining to 279 patients undergoing primary FP BS or PBA for CLTI in the period 2009 to 2014. We report baseline characteristics, 30-day morbidity and mortality, major adverse cardiovascular events (MACE) and long-term AFS, limb salvage (LS), OS, major adverse limb events (MALE), and freedom from re-intervention (FFR). RESULTS 234 (84%) and 45 (16%) patients underwent PBA and BS respectively. PBA patients were significantly older (77 vs 71 years, P = 0.001) and more likely to be female (45% vs 28%, P = 0.026). Bollinger and GLASS anatomic scores were significantly more severe in the BS group. Technical success was better for BS (100% vs 87%, P = 0.007). Index hospital stay was shorter for PBA (9.1 vs 15.6 days, P = 0.035) but there was no difference in hospital days or admissions over the next 12 months. AFS (HR 1.00), LS (HR 1.44), OS (HR 0.81), MALE (HR 1.25) and FFR (HR = 1.00) were not significantly different between PBA and BS. CONCLUSION Important clinical outcomes following FP BS and PBA for CLTI have not changed significantly in our unit in the 10 years following the BASIL-1 trial. BASIL-1 therefore remains relevant to our current practice and should inform our approach to the management of CLTI going forward.

Abstract
INTRODUCTION A published subgroup analysis of the Bypass versus Angioplasty in Severe Ischaemia of the Leg (BASIL)-1 trial suggests that, in patients with chronic limb threatening ischemia (CLTI) due to infra-popliteal (IP) disease, clinical outcomes are better following vein bypass surgery (BS) than after plain balloon angioplasty (PBA). The aim of the present study is to determine if clinical outcomes following IP revascularization in our unit are concordant with those found in BASIL-1. METHODS We analyzed prospectively gathered data pertaining to 137 consecutive CLTI patients undergoing IP PBA or BS between 2009 and 2013. We compared 30-day morbidity and mortality, days in hospital (index admission and out to 12-months), amputation free survival (AFS), overall survival (OS), limb salvage (LS), and freedom from arterial re-intervention (FFR). Patient outcomes were censored on 1 February 2017, providing a minimum 3 years follow-up. RESULTS Patients undergoing BS (73/137, 47%) tended to be younger, have less comorbidity, and were more likely to be on best medical therapy (BMT). BS patients spent more days in hospital during the index admission (median 9 vs 5, p = .003), but not out to 12 months (median 15 vs 13, NS). BS patients suffered more 30-day morbidity (36% vs 10%, p < .001), mainly due to infective complications, but not mortality (3.1% vs 6.8%, NS). AFS (p = .001) and OS (p < .001), but not LS or FFR, were better after BS. CONCLUSIONS CLTI patients selected for revascularization by means of IP BS had better long-term outcomes in terms of AFS and OS, but not FFR or LS. Although we await the results of the BASIL-2 trial, current data support the BASIL-1 sub-group analysis which suggests that patients requiring revascularization for IP disease should have BS where possible and that PBA should usually be reserved for patients who are not suitable for BS.

Abstract
Objectives: To compare outcomes in patients randomized to infrapopliteal (IP) plain balloon angioplasty (PBA) for chronic limb-threatening ischemia within the Bypass versus Angioplasty in Severe Ischemia of the Leg (BASIL)-1 trial between 1999 and 2004 with outcomes in consecutive patients undergoing IP PBA at an academic vascular unit a decade later (2009-2013, Contemporary series [CS]). Methods: Individual patient data were obtained from prospective BASIL-1 (48 patients) and CS databases (73 patients). All had a minimum of 3-years of follow-up. Outcomes studied were amputation-free survival (AFS), overall survival (OS), major (above ankle) limb amputation, arterial reintervention, immediate technical success, and length of hospital stay for the index procedure and during the following 12-month period. Statistical analysis was performed using SAS version 9.4. Results: The BASIL and CS cohorts were well matched for gender, age, diabetes, previous stroke, myocardial infarction and arterial intervention, and presence of tissue loss. More patients in BASIL-1 underwent concomitant treatment of the superficial femoral (60% vs 37%, P = .01) and above knee popliteal (60% vs 34%, P = .005) arteries. Immediate technical success increased from 73% in BASIL-1 to 90% in the CS ( P = .01). Between the two cohorts, there were no differences in AFS (hazard ratio [HR] = 1.00, 95% confidence interval [CI]: 0.65-1.54, P = 1.0), OS (HR = 1.04, 95% CI: 0.66-1.62, P = .9), major amputation (HR = 0.86, 95% CI: 0.37-1.97, P = .7), or reintervention (HR = 0.61, 95% CI: 0.29-1.27, P = .2). Contemporary series patients spent significantly fewer days in hospital following the index procedure ( P = .02) and also over the following 12 months ( P = .002). Conclusions: Despite improvements in the immediate technical angiographic success of IP PBA between BASIL and the CS, there were no significant improvements in survival outcomes. Results from BASIL-2 and BEST-CLI are required in order to properly define the clinical and cost-effectiveness of endovascular treatment in such patients.

Abstract
GUIDELINE SUMMARY Chronic limb-threatening ischemia (CLTI) is associated with mortality, amputation, and impaired quality of life. These Global Vascular Guidelines (GVG) are focused on definition, evaluation, and management of CLTI with the goals of improving evidence-based care and highlighting critical research needs. The term CLTI is preferred over critical limb ischemia, as the latter implies threshold values of impaired perfusion rather than a continuum. CLTI is a clinical syndrome defined by the presence of peripheral artery disease (PAD) in combination with rest pain, gangrene, or a lower limb ulceration >2 weeks duration. Venous, traumatic, embolic, and nonatherosclerotic etiologies are excluded. All patients with suspected CLTI should be referred urgently to a vascular specialist. Accurately staging the severity of limb threat is fundamental, and the Society for Vascular Surgery Threatened Limb Classification system, based on grading of Wounds, Ischemia, and foot Infection (WIfI) is endorsed. Objective hemodynamic testing, including toe pressures as the preferred measure, is required to assess CLTI. Evidence-based revascularization (EBR) hinges on three independent axes: Patient risk, Limb severity, and ANatomic complexity (PLAN). Average-risk and high-risk patients are defined by estimated procedural and 2-year all-cause mortality. The GVG proposes a new Global Anatomic Staging System (GLASS), which involves defining a preferred target artery path (TAP) and then estimating limb-based patency (LBP), resulting in three stages of complexity for intervention. The optimal revascularization strategy is also influenced by the availability of autogenous vein for open bypass surgery. Recommendations for EBR are based on best available data, pending level 1 evidence from ongoing trials. Vein bypass may be preferred for average-risk patients with advanced limb threat and high complexity disease, while those with less complex anatomy, intermediate severity limb threat, or high patient risk may be favored for endovascular intervention. All patients with CLTI should be afforded best medical therapy including the use of antithrombotic, lipid-lowering, antihypertensive, and glycemic control agents, as well as counseling on smoking cessation, diet, exercise, and preventive foot care. Following EBR, long-term limb surveillance is advised. The effectiveness of nonrevascularization therapies (eg, spinal stimulation, pneumatic compression, prostanoids, and hyperbaric oxygen) has not been established. Regenerative medicine approaches (eg, cell, gene therapies) for CLTI should be restricted to rigorously conducted randomizsed clinical trials. The GVG promotes standardization of study designs and end points for clinical trials in CLTI. The importance of multidisciplinary teams and centers of excellence for amputation prevention is stressed as a key health system initiative.

Vein bypass may be preferred for average-risk patients with advanced limb threat and high complexity disease, while those with less complex anatomy, intermediate severity limb threat, or high patient risk may be favored for endovascular intervention. All patients with CLTI should be afforded best medical therapy including the use of antithrombotic, lipid-lowering, antihypertensive, and glycemic control agents, as well as counseling on smoking cessation, diet, exercise, and preventive foot care. Following EBR, long-term limb surveillance is advised. The effectiveness of nonrevascularization therapies (eg, spinal stimulation, pneumatic compression, prostanoids, and hyperbaric oxygen) has not been established. Regenerative medicine approaches (eg, cell, gene therapies) for CLTI should be restricted to rigorously conducted randomizsed clinical trials. The GVG promotes standardization of study designs and end points for clinical trials in CLTI. The importance of multidisciplinary teams and centers of excellence for amputation prevention is stressed as a key health system initiative.

Abstract
Background NICE Clinical Guidelines (CG) 168, published in July 2013, recommend specialist vascular referral for all leg ulcers, defined as a break in the skin below the knee that has not healed within two weeks. Aim To examine the impact of CG168 on the primary care management of leg ulcers using The Health Improvement Network database. Methods An eligible population of approximately two million adult patients was analysed over two 18-month periods before and after publication of CG168. Those with a new diagnosis of leg ulcers in each time period were analysed in terms of demographics, specialist referral and superficial venous ablation. Results We identified 7532 and 7462 new diagnoses of leg ulcers in the pre- and post-CG168 cohorts, respectively. Patients with a new diagnosis of leg ulcers were elderly (median age: 77 years both cohorts) and less likely to be male (47% both cohorts). There were 2259 (30.0%) and 2329 (31.2%) vascular service referrals in the pre- and post-CG168 cohorts, respectively (hazard ratio, 1.05, 95% CI: 0.99, 1.11, p = 0.096). The median interval between general practitioner diagnosis and referral was 1.5 days in both cohorts. Patients from both cohorts who were referred for a new diagnosis of leg ulcers were equally likely to receive superficial venous ablation. Conclusions Disappointingly, we have been unable to demonstrate that publication of NICE CG168 has been associated with a meaningful change in leg ulcer management in primary care in line with guideline recommendations.

Abstract
OBJECTIVE/BACKGROUND In a pilot study, a relationship between abdominal aortic aneurysm (AAA) diameter and serum interleukin (IL)-1α levels was reported, and that endothelial cell (EC) activation in vitro in response to serum from patients with AAA was blocked by anti-IL-1α antibodies. The aim of the present study was to further investigate the relationship between serum IL-1α and asymptomatic infrarenal AAA size, morphology, and growth rates. METHODS Serum IL-1α was measured using enzyme linked immunosorbent assay in 101 patients with asymptomatic, infrarenal AAA and related to aneurysm size, morphology, and growth rates. RESULTS IL-1α was measured in 101 patients. There was no statistically significant difference in mean age between men and women. IL-1α was detectable in 62.4% of patients; median IL-1α titre was 3.26 pg/mL. There was no statistically significant relationship between IL-1α and maximum AAA antero-posterior diameter as measured by ultrasound (p = .649), AAA morphology (aortic length [p = .394], sac [p = .369], and thrombus volume [p = .629]) as measured on computed tomography, absolute increase in AAA diameter (p = .214), or AAA growth rate (p = .230). CONCLUSION IL-1α is detectable in the majority of patients with infrarenal AAA, but the cause and clinical significance of this novel observation remains unknown.

Abstract
BACKGROUND For a cytokine to have a role as a clinically useful biomarker, it must be measureable in a practical, reliable, and reproducible manner. Furthermore, assays from different manufacturers should produce comparable results. The aim of this paper was to examine the effect of 2 sample processing methodologies and compare 9 commercially available immunoassays for their measurement of serum interleukin (IL)-1α in patients with abdominal aortic aneurysm. METHODS Two sample processing methodologies and 9 manufacturers' immunoassays were compared. Each immunoassay was also tested for detection of both IL-1α isoforms. RESULTS A positive signal for IL-1α was found in all serum samples, in all immunoassays, using both processing methods. In the majority, titer concentrations were unquantifiable with values below manufacturers' detectable range. Variability in titer concentrations was seen across all immunoassays. With the exception of 1 immunoassay, all were able to detect both IL-1α isoforms. CONCLUSIONS Researchers wishing to measure serum cytokines levels should be aware that differences in sample processing methods and manufacturers' immunoassays can affect the results. This may result in misleading conclusions being drawn about biological processes underpinning a wide range of inflammatory diseases.

Abstract
OBJECTIVE The aim was to compare outcomes in a subgroup of patients with infrapopliteal (IP) disease randomised to infrapopliteal vein bypass (VB) or plain balloon angioplasty (PBA) in the original BASIL trial. METHODS A comparison of outcomes from patients randomised to VB or PBA undergoing revascularisation for severe limb ischaemia (SLI) because of IP disease with or without femoropopliteal disease. Data were extracted from case report forms from the BASIL trial. The primary outcome was amputation free survival (AFS); secondary outcomes included overall survival (OS), 30 day mortality and morbidity, freedom from arterial re-intervention, immediate technical success, repeat and crossover interventions, length of hospital stay, and quality of revascularisation. RESULTS A total of 104 patients were identified in the BASIL study with IP disease, 56 randomised to IP VB, and 48 to IP PBA. Groups were similar at baseline except for more chronic kidney disease and non-steroidal anti-inflammatory drug use in the VB group, and more previous surgical arterial intervention and antihypertensive use in the PBA group. There were no statistically significant differences in AFS or OS; however, clinically important trends were apparent in favour of a VB first strategy. Patients allocated to VB demonstrated significantly quicker relief of rest pain when compared with PBA (p = .005), but no significant differences in improved tissue healing. Median length of index hospital admission was significantly greater in the VB than in the PBA group (18 vs. 10 days, p < .0001) but there was no difference between the two groups in median total hospital stay between randomisation and the primary endpoint (VB 43.5 vs. PBA 42 days). CONCLUSIONS Further randomised trials, like BASIL-2 and BEST-CLI, are required to determine whether patients with severe limb ischaemia who require IP revascularisation and who are suitable for VB should have bypass or endovascular intervention as their primary revascularisation procedure.

Abstract
Background Leg ulcers are a common cause of morbidity and disability and result in significant health and social care expenditure. The UK National Institute for Health and Care Excellence (NICE) Clinical Guideline (CG)168, published in July 2013, sought to improve care of patients with leg ulcers, recommending that patients with a break in the skin below the knee that had not healed within two weeks be referred to a specialist vascular service for diagnosis and management. Aim Determine the impact of CG168 on referrals to a leg ulcer service. Methods Patients referred with leg ulceration during an 18-month period prior to CG168 (January 2012–June 2013) and an 18-month period commencing six months after (January 2014–June 2015) publication of CG168 were compared. Results There was a two-fold increase in referrals (181 patients, 220 legs vs. 385 patients, 453 legs) but no change in mean age, gender or median-duration of ulcer at referral (16.6 vs. 16.2 weeks). Mean-time from referral to specialist appointment increased (4.8 vs. 6 weeks, p = 0.0001), as did legs with superficial venous insufficiency (SVI) (36% vs. 44%, p = 0.05). There was a trend towards more SVI endovenous interventions (32% vs. 39%, p = 0.271) with an increase in endothermal (2 vs. 32 legs, p = 0.001) but no change in sclerotherapy (24 vs. 51 legs) treatments. In both groups, 62% legs had compression. There was a reduction in legs treated conservatively with simple dressings (26% vs. 15%, p = 0.0006). Conclusions Since CG168, there has been a considerable increase in leg ulcer referrals. However, patients are still not referred until ulceration has been present for many months. Although many ulcers are multi-factorial and the mainstay of treatment remains compression, there has been an increase in SVI endovenous intervention. Further efforts are required to persuade community practitioners to refer patients earlier, to educate patients and encourage further investment in chronically underfunded leg ulcer services.

Abstract
Background UK National Institute for Health and Care Excellence (NICE) clinical guidelines (CG) 168, published in July 2013, aimed to improve the management of lower limb venous disease by newly recommending interventional treatment for all people affected by symptomatic varicose veins (VV) and specialist vascular referral for all people suffering from a leg ulcer (LU) that had been present for ≥2 weeks. This study aims to determine if CG168 has increased access to vascular services, particularly for the socially deprived, who might be expected to have greater need for such services. Methods The study was performed in a highly multi-cultural, socio-economically diverse, mixed urban/suburban population of approximately 1.2 million people living in and around East Birmingham, UK. Index of multiple deprivation quintile (IMD-Q) was used as a measure of social deprivation to compare levels of social deprivation of people undergoing interventions for symptomatic VV or referred with an LU during 18-month periods before and after the publication of CG168. The referring general practitioner practices (GPPs) were also recorded. Results There was no change in overall IMD-Q distribution before and after CG168 in terms of VV interventions. However, there was a non-significant increase in proportions of people classified as IMD-Q5 (the most deprived quintile). After CG168, fewer IMD-Q5 people with LU were referred, with a shift in referrals towards those from less socially deprived areas. More GPP referred people with both VV and LU after CG168, and those that referred patients before and after CG168 tended to refer more after CG168. Conclusions CG168 has increased VV interventions as well as the number referred with LU. However, this improvement in access to treatment and referral may have disproportionately favoured the more socio-economic privileged. Professional and public education is required to ensure that the beneficial impact of the CG168 recommendations are maximised and that those with the greatest health needs have equal access to evidence-based management of their venous disease.

Abstract
Objective: To compare the safety and efficacy of Varisolve® 1% polidocanol microfoam sclerosant with alternative treatments for patients with varicose veins and trunk vein incompetence. Methods: An open-label, multicentre, prospective trial of 710 patients randomized to receive either Varisolve® or alternative treatment (surgery or sclerotherapy). The endpoint was ultrasound-determined occlusion of trunk vein(s) and elimination of reflux, analysed against a non-inferiority hypothesis. Results: Overall, non-inferiority was demonstrated with 83.4% efficacy for Varisolve® compared with 88.1% for alternative treatment at three months, and the corresponding magnitudes were 78.9 and 80.4% at 12 months. Surgery was superior to Varisolve®, but the success rate of 68.2% for Varisolve® (surgery 87.2%) was poor compared with 93.8% success for Varisolve® achieved in those randomized to Varisolve® or sclerotherapy. Varisolve® was superior to sclerotherapy at 12 months ( P = 0.001). Deep vein thrombosis occurred in 11/437 (2.5%) after Varisolve®, in 1/125 (0.8%) after sclerotherapy and in none after surgery. No pulmonary emboli were detected. Conclusion: Overall, Varisolve® was non-inferior to alternative treatment. Surgery was more efficacious, but Varisolve® caused less pain and patients returned to normal more quickly. The Varisolve® technique is a useful additional treatment for varicose veins and trunk vein incompetence.

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

Abstract
OBJECTIVE Although varicose veins are a common cause of morbidity, the UK National Health Service and private medical insurers have previously sought to ration their treatment in a non-evidence based manner in order to limit health-care expenditure and reimbursement. In July 2013, the UK National Institute for Health and Care Excellence published new national Clinical Guidelines (CG168) to promote evidence-based commissioning and management of varicose veins. The aim of this study was to evaluate the impact of CG168 on the referral and management of varicose veins at the Heart of England NHS Foundation Trust, Birmingham, UK. METHODS Interrogation of a prospectively gathered database, provided by the Heart of England NHS Foundation Trust Performance Unit, of patients undergoing interventions for varicose veins since 1 January 2012. Patients treated before (group 1) and after (group 2) publication of CG168 were compared. RESULTS There were 253 patients, 286 legs (48% male, mean (range) age 54 (20-91) years) treated in group 1, and 417 patients, 452 legs, (46% male, mean (range) age 54 (14-90) years) treated in group 2, an increase of 65%. CG168 was associated with a significant reduction in the use of surgery (131 patients (52%) group 1 vs. 127 patients (30%) group 2, p = 0.0003, χ(2)), no change in endothermal ablation (30 patients (12%) group 1 vs. 45 patients (11%) group 2), a significant increase in ultrasound-guided foam sclerotherapy (92 patients (36%) group 1 and 245 patients (59%) group 2, p = 0.0001, χ(2)) and an increase in treatment for C2/3 disease (53% group 1 and 65.2% group 2, p = 0.0022, χ(2)). CONCLUSIONS Publication of National Institute for Health and Care Excellence CG168 has been associated with a significant increase (65%) in the number of patients treated, referral at an earlier (CEAP C) stage and increased use of endovenous treatment. CG 168 has been highly effective in improving access to, and quality of care, for varicose veins at Heart of England NHS Foundation Trust.

Abstract
Objective The last 10 years have seen the introduction into everyday clinical practice of a wide range of novel non-surgical treatments for varicose veins. In July 2013, the UK National Institute for Health and Care Excellence recommended the following treatment hierarchy for varicose veins: endothermal ablation, ultrasound-guided foam sclerotherapy, surgery and compression hosiery. The aim of this paper is to review the randomised controlled trials that have compared endothermal ablation and ultrasound-guided foam sclerotherapy to determine if the level 1 evidence base still supports an “endothermal ablation first” strategy for the treatment of varicose veins. Methods A PubMed and OVID literature search (until 31 January 2015) was performed and randomised controlled trials comparing endothermal ablation and ultrasound-guided foam sclerotherapy were obtained. Results Although anatomical success appeared higher with endothermal ablation than ultrasound-guided foam sclerotherapy, clinical success and patient-reported outcomes measures were similar. Morbidity and complication rates were very low and not significantly different between endothermal ablation and ultrasound-guided foam sclerotherapy. Ultrasound-guided foam sclerotherapy was consistently less expensive that endothermal ablation. Conclusions All endovenous modalities appear to be successful and have a role in modern day practice. Although further work is required to optimise ultrasound-guided foam sclerotherapy technique to maximise anatomical success and minimise retreatment, the present level 1 evidence base shows there is no significant difference in clinical important outcomes between ultrasound-guided foam sclerotherapy and endothermal ablation. As ultrasound-guided foam sclerotherapy is less expensive, it is likely to be a more cost-effective option in most patients in most healthcare settings. Strict adherence to the treatment hierarchy recommended by National Institute for Health and Care Excellence seems unjustified.

Abstract
Abstract
Background
The aim was to determine the long-term (5–8 years) outcomes of ultrasound-guided foam sclerotherapy (UGFS) for varicose veins using health-related quality of life (HRQL), patient-reported outcomes (PROMs), patient satisfaction and retreatment rates.
Methods
Consecutive patients undergoing UGFS between April 2004 and May 2007 were invited for review at least 5 years after treatment. Patients completed generic (Short Form 12) and disease-specific (Aberdeen Varicose Vein Symptom Severity Score, AVSS) HRQL instruments, and questionnaires enquiring about lower limb symptoms, lifestyle factors and satisfaction with treatment. Data on retreatments were recorded prospectively.
Results
A total of 391 limbs in 285 patients were included (81·2 per cent response rate) at a median of 71 (i.q.r. 67–78) months following first UGFS treatment. Originally 72·1 per cent had symptomatic, uncomplicated varicose veins, 21·9 per cent had undergone surgery previously, 87·2 per cent had treatment of great saphenous veins and 19·9 per cent treatment of short saphenous veins. Disease-specific HRQL scores improved significantly at long-term follow-up, with 88·5 per cent having an improved AVSS compared with baseline. Regarding lower limb symptoms and lifestyle improvement, 62·7–93·8 per cent of patients had their pretreatment expectations met or exceeded. Overall, 82·0 per cent were very satisfied with their treatment and only 3·3 per cent were dissatisfied; 91·0 per cent would recommend the treatment to others. Some 15·3 per cent of limbs required retreatment by 5 years (Kaplan–Meier analysis).
Conclusion
UGFS has durable results as reported by PROMs to at least 5 years. Only 15·3 per cent of limbs required retreatment for recurrence during follow-up.

Abstract
OBJECTIVES To determine the relationship between lower limb symptoms and generic health-related quality of life (HRQL) in patients with varicose veins (VV). METHODS 284 patients on the waiting list for VV treatment completed the Short Form-12 (SF12) and a questionnaire asking about the presence of lower limb symptoms commonly attributed to venous disease (pain or ache, itching, tingling, cramp, restless legs, a feeling of swelling, and heaviness). RESULTS Median age was 57 years (interquartile range 45-67); 100 (35%) were male, and 182 (64%) had CEAP clinical grade 2 or 3 disease. Jonckheere-Terpstra test for trend revealed that both physical (P < .0005) and mental (P = .001) HRQL worsened as the reported number of symptoms increased. Patients reporting tingling (P = .016, Mann-Whitney U test), cramp (P = .001), restless legs (P < .0005), swelling (P < .0005), and heaviness (P < .0005) had a significantly worse physical HRQL than those who did not. Mental HRQL was also significantly worse in patients with tingling (P = .010), cramp (P = .008), restless legs (P = .040), swelling (P = .001), and heaviness (P = .035). These significant relationships remained, and pain was also correlated with worse physical HRQL (P = .011), when linear regression was performed to control for CEAP clinical grade, age and sex. CONCLUSIONS Physical and mental HRQL is significantly worse in VV patients with lower limb symptoms irrespective of the clinical stage of disease. This observation confirms that VV are not primarily a cosmetic problem and that NHS rationing of treatment to those with CEAP C4-6 disease excludes many patients who would benefit from intervention in terms of HRQL. Generic HRQL instruments also allow comparison with interventions for other chronic conditions.
