Abstract
Background: In vascular medicine, peripheral arterial disease (PAD) and diabetic foot syndrome (DFS) are often considered synonymous with respect to the need for revascularization. In PAD patients, clinical symptoms reflect the degree of atherosclerotic disease, since peripheral innervation, including pain sensation, is not usually compromised. In DFS patients, however, symptoms of relevant foot ischemia are often absent and progression of ischemia goes unnoticed owing to diabetic polyneuropathy, the loss of nociception being the main trigger for foot ulcers. This review analyzes the fundamental differences between PAD and DFS against the background of polyneuropathy. Methods: The literature research for the 2014 revision of the German evidence-based S3-PAD-guidelines was extended to 2023. Results: Vascular examination is imperative for both, PAD and DFS. Stage-dependent revascularization is of utmost importance in PAD patients, especially those suffering from critical limb-threatening ischemia (CLTI). Successful therapy of DFS goes further, including infection and metabolic control, wound management, offloading the foot and lifelong prophylaxis in the course of a multidisciplinary treatment concept. Revascularization is not needed in all cases of DFS. Conclusions: There are fundamental differences between PAD and DFS with respect to pathophysiology, the anatomical distribution of arterial occlusive processes, the clinical symptoms, the value of diagnostic tools such as the ankle-brachial index, and classification. Also, therapeutic concepts differ substantially between the two patient populations.

Abstract
Background: Lower extremity arterial disease (LEAD) is caused by atherosclerotic plaque in the arterial supply to the lower limbs. The neutrophil to lymphocyte and platelet to lymphocyte ratios (NLR, PLR) are established markers of systemic inflammation which are related to inferior outcomes in multiple clinical conditions, though remain poorly described in patients with LEAD. Material and methods: This review was carried out in accordance with PRISMA guidelines. The MEDLINE database was interrogated for relevant studies. Primary outcome was the prognostic effect of NLR and PLR on clinical outcomes following treatment, and secondary outcomes were the prognostic effect of NLR and PLR on disease severity and technical success following revascularisation. Results: There were 34 studies included in the final review reporting outcomes on a total of 19870 patients. NLR was investigated in 21 studies, PLR was investigated in two studies, and both NLR & PLR were investigated in 11 studies. Relating to increased levels of systemic inflammation, 20 studies (100%) reported inferior clinical outcomes, 13 (92.9%) studies reported increased disease severity, and seven (87.5%) studies reported inferior technical results from revascularisation. Conclusions: The studies included in this review support the role of elevated NLR and PLR as key components influencing the clinical outcomes, severity, and success of treatment in patients with LEAD. The use of these easily accessible, cost effective and routinely available markers is supported by the present review.

Abstract
Patients with chronic limb-threatening ischemia, the terminal stage of peripheral artery disease, are frequently afflicted by below-the-knee disease. Although all patients should receive guideline-directed medical therapy, restoration of inline flow is oftentimes necessary to avoid limb loss. Proper patient selection and proficiency in endovascular techniques for below-the-knee revascularization are intended to prevent major amputation and promote wound healing. This review, a consensus among an international panel of experienced operators, provides guidance on these challenges from an endovascular perspective and offers techniques to navigate this complex disease process.

Abstract
OBJECTIVE There is no established consensus or guidelines for wound management after revascularization for patients with chronic limb-threatening ischemia (CLTI) without severe infection. This study is designed to evaluate the clinical effect of the wound management strategy on toe wounds after revascularization for CLTI. METHODS This retrospective cohort study was performed at eight institutions affiliated with Keio University School of Medicine in Japan and included 261 patients who underwent revascularization for CLTI between April 2019 and July 2021. We identified 132 patients with toe wounds from the database who had restored in-line blood flow to the foot. Patients were divided into two groups by the timing of toe resection after revascularization, which dictated the wound management policy. Group A (62 patients) underwent early toe amputation for suspected osteomyelitis, whereas group B (70 patients) underwent watchful waiting. The primary outcome was wound healing after revascularization; the secondary outcome was major amputation. We compared outcomes between groups A and B after propensity score matching. RESULTS Using propensity score matching, each patient in group A (33 patients) was matched with a patient in group B (33 patients). Wound healing in matched group A was significantly better than that in matched group B (respectively: 1-year wound healing rate: 90.0% vs 68.2%, P < .001; median wound healing time: 65 days vs 258 days, P < .01). Although five major amputations were necessary in matched group B, none were required in matched group A (P = .05). The high rate of major amputations in group B was attributed to the sudden exacerbation of infection. Limb salvage rate in matched group A exceeded matched group B (100.0% vs 90.5%: 1-year limb salvage rate, P = .02). CONCLUSIONS Early toe amputation for highly suspected osteomyelitis in patients with CLTI with toe wounds may expedite wound healing compared with watchful waiting, potentially avoiding unnecessary major amputation. Considering the wound management strategy is crucial when evaluating wound healing outcomes in patients with CLTI with revascularization.

Abstract
Timely revascularization is essential for limb salvage and to reduce mortality in patients with chronic limb-threatening ischemia (CLTI). In patients who are candidates for endovascular therapy and surgical bypass, the optimal revascularization strategy remains uncertain. Recently published randomized controlled trials (RCTs) have presented conflicting results. We conducted a trial-level meta-analysis to compare the outcomes between endovascular-first and surgery-first strategies for revascularization. PubMed, Web of Science, and the Cochrane Library were searched to identify RCTs comparing the outcomes of endovascular-first versus surgery-first strategies for revascularization in patients with CLTI. Data were pooled for major outcomes and their aggregate risk ratios (RRs) with 95% confidence intervals were calculated using a random-effects model. Kaplan-Meier curves for amputation-free survival and overall survival time were plotted using the pooled aggregated data from published curves, with their corresponding hazard ratios (HRs) and 95% confidence intervals reported for up to 5 years of follow-up. A total of 3 RCTs with 2,627 patients (1,312 endovascular-first and 1,315 surgery-first) were included in the meta-analysis. Of these, 1,864 patients (70.9%) were men and 347 (13.2%) were older than 80 years. Comparing the endovascular-first and surgery-first approaches, there was no significant difference in the overall (HR 0.92 [0.83 to 1.01], p = 0.09) or amputation-free survival (HR 0.98 [0.92 to 1.03], p = 0.42), reintervention (RR 1.24 [0.74 to 2.07], p = 0.41), major amputation, (RR 1.16 [0.87 to 1.54], p = 0.31), or therapeutic crossover (RR 0.92 [0.37 to 2.26], p = 0.85). In conclusion, data from available RCTs suggest that there is no difference in clinical outcomes between endovascular-first and surgery-first revascularization strategies for CLTI. A planned patient-level meta-analysis may provide further insight.

Abstract
Eliminating necrotic and infected tissues is crucial for limb salvage in patients with chronic limb-threatening ischemia (CLTI). However, extensive lesions that involve the midfoot frequently result in transtibial amputation, restricting ambulation and independent life. The Modified Pirogoff amputation, which includes a 90° rotation of the calcaneus and fixation with the tibia, has good functional outcomes in trauma cases. Here, we report two patients with CLTI successfully managed by a combination of revascularization and modified Pirogoff amputation, resulting in preserved ambulation without a prosthesis. Modified Pirogoff amputation may be a good alternative in revascularized CLTI with extensive tissue loss of the midfoot.

Abstract
Background: Peripheral artery disease (PAD) frequently leads to hospital admission. Sex related differences in in-patient care are a current matter of debate. Patients and methods: Data were provided from the German national in-patient sample provided by the Federal Bureau of Statistics (DESTATIS). Trends on risk profiles, therapeutic procedures, and outcomes were evaluated from 2014 until 2019 stratified by sex and PAD severity. Results: Two-thirds of an annual >191,000 PAD in-patient cases applied to male sex. Chronic limb-threatening ischemia (CLTI) was recorded in 49.6% of male and 55.2% of female cases (2019). CLTI was as a major risk factor of in-hospital amputation (OR 229) and death (OR 10.5), whereas endovascular revascularisation (EVR) with drug-coated devices were associated with decreased risk of in-hospital amputation (OR 0.52; all p<0.001). EVR applied in 47% of CLTI cases compared to 71% in intermittent claudication (IC) irrespective of sex. In-hospital mortality was 4.3% in male vs. 4.8% in female CLTI cases, minor amputations 18.4% vs. 10.9%, and major amputation 7.5% vs. 6.0%, respectively (data 2019; all p<0.001). After adjustment, female sex was associated with lower risk of amputation (OR 0.63) and death (OR 0.96) during in-patient stay. Conclusions: Male PAD patients were twice as likely to be admitted for in-patient treatment despite equal PAD prevalence in the general population. Among in-patient cases, supply with invasive therapy did not relevantly differ by sex, however is strongly reduced in CLTI. CLTI is a major risk factor of adverse short-term outcomes, whereas female sex was associated with lower risk of in-patient amputation and/or death.

Abstract
Peripheral arterial disease (PAD) is common in patients with symptomatic aortic stenosis. PAD exists as a spectrum, and patients with chronic limb-threatening ischemia (CLTI), the most severe form of PAD, are at high risk for limb loss and death. We seek to determine patient characteristics and clinical outcomes among patients who underwent TAVR with or without CLTI. We identified all hospitalizations for TAVR from October 2015 to December 2018 using the National Inpatient Sample database. Patients with any diagnosis of CLTI were identified using the International Classification of Diseases 10th Revision codes. The primary outcome was in-hospital mortality, and secondary outcomes were major complications, open revascularization, and endovascular revascularization after TAVR. During the study period, a total of 31,335 hospitalizations for TAVR procedures were included, including 7,048 (22.5%) in patients with CLTI. CLTI was associated with higher in-hospital mortality (odds ratio [OR] 1.4, 95% confidence interval [CI] 1.13 to 1.74, p = 0.002) and major complications (OR 1.2, 95% CI 1.09 to 1.25, p <0.001). CLTI was also associated with a significantly higher rate of open limb revascularization (OR 5.1, 95% CI 3.94 to 6.48, p <0.001) and endovascular revascularization (OR 4.0, 95% CI 3.54 to 4.59, p <0.001). CLTI among patients who underwent TAVR is associated with higher in-hospital mortality, major complications, and longer lengths of stay compared with patients without CLTI. However, the overall rates of adverse events remain low. Further studies are needed to optimize the multidisciplinary care of these patients before TAVR with a focus on shared decision-making.

Abstract
This Commentary highlights the under-recognized prevalence and heavy burden of peripheral artery disease (PAD) and its important role as a harbinger of complications of atherosclerotic cardiovascular disease. Although increasing in prevalence globally, PAD is being further accelerated with diabetes, and patients with advanced PAD are at high risk for chronic limb-threatening ischemia. The need for (repeated) revascularization and amputation places a heavy social burden on patients and family, and a heavy financial burden on the health care system, exceeding the cost of coronary artery and cerebrovascular diseases. Clinical trial research in PAD will be enhanced by widely agreed-upon definitions of major adverse cardiovascular events and major adverse limb events. Antithrombotic and lipid-lowering therapies are recommended but underutilized, while the optimal peri-interventional antithrombotic regimen is still under debate. Additional antiinflammatory treatment is currently an unaddressed strategy in the management of patients with PAD, and there is a strong case for the evaluation of widely available antiinflammatory agents such as colchicine.

Background: Ageing is a major cardiovascular risk factor with detrimental changes that culminate in a high atherosclerotic burden. Peripheral artery disease (PAD) is a major manifestation of atherosclerosis with high mortality. Guideline-recommended treatment is essential, however implementation is inadequate. With an ageing society, age-related inequalities are important and have not been elucidated in a high-risk PAD population on a nation-wide scale. We sought to analyse outpatient treatment structures and guideline adherence in treatment of PAD patients older than 80 years. Patients and methods: The study is based on ambulatory claims data comprising 70.1 million statutorily insured patients per year in Germany from 2009 to 2018. We analysed age-related differences in prevalence, pharmacotherapy and specialized outpatient care in PAD patients. Results: Of 17,633,970 PAD patients included, 28% were older than 80 years. PAD prevalence increased between 2008 and 2018 (1.85% vs. 3.14%), with the proportion of older patients increasing by a third (24.4% vs. 31.2%). Octogenarians were undertreated regarding guideline-recommended statin pharmacotherapy compared to younger patients while antiplatelets were prescribed more often (statins 2016: 46.5% vs. 52.4%; antiplatelets 2016 30.6% vs. 29.3%; p<.05). Furthermore, octogenarians received less specialized outpatient care (angiology: 6.4% vs. 9.5%, vascular surgery: 8.1% vs. 11.8%, cardiology: 25.2% vs. 29.2%, p<.05). Conclusions: Our results demonstrate that age-related differences in pharmacotherapy and specialized outpatient care of PAD patients are evident. While overall guideline-recommended outpatient treatment is low, patients 80 years and older are less likely to receive both, leaving age-related health inequalities a challenge of our future.

Abstract
PURPOSE Vessel calcification is estimated to be present in 30% to 50% of patients with peripheral arterial disease (PAD) and is one of the main challenges in endovascular treatment. The popliteal artery is unique compared with other arteries due to its exposure to significant deformation and biomechanical stress during knee motion. Intravascular lithotripsy (IVL) is a novel technique that uses acoustic pressure waves to cause microfractures within the intimal and medial wall calcification. Intravascular lithotripsy is safe in femoropopliteal and infrapopliteal lesions, but follow-up studies are lacking. Therefore, the purpose of this study was to describe the first follow-up outcomes of IVL in popliteal and infrapopliteal arterial disease. METHODS This prospective, multicenter cohort study included all patients treated with IVL in the popliteal and infrapopliteal arteries at 4 sites. Standardized follow-up with duplex ultrasonography was scheduled at 6 to 8 weeks and 12 months. The primary safety endpoint was a composite of major adverse events (MAEs) at 30 days. Primary efficacy endpoints were primary patency, limb salvage, and amputation-free survival (AFS) at 12 months. Secondary endpoints were primary-assisted patency and freedom from target lesion revascularization (TLR). Endpoints were distributed for patients with chronic limb-threatening ischemia (CLTI) and intermittent claudication (IC) and estimated using the Kaplan-Meier method. RESULTS Between April 2021 and March 2023, 29 patients with 30 limbs were treated. Diabetes mellitus (DM) and CLTI were present in 62.1% and 80.0% of patients, respectively. Within the 32 treated lesions, severe calcification was present in 84.4% and bailout stenting was necessary in 12.5% of the lesions. Four MAEs occurred within 30 days: 1 closure device failure, 1 major amputation, and 2 deaths, neither of which was related to the study device. The primary patency, primary-assisted patency, freedom from TLR, limb salvage, and AFS at 12 months were 68.8%, 90.0%, 93.3%, 83.9%, and 57.1% for CLTI patients, respectively. No events occurred in restenosis, re-occlusion, TLR, major amputation, or mortality in patients with IC. CONCLUSIONS This first-ever analysis on follow-up outcomes of IVL in the popliteal and infrapopliteal arteries demonstrated promising safety and efficacy outcomes with a low rate of bailout stenting. CLINICAL IMPACT Vessel calcification is a common feature in peripheral arterial disease (PAD) and is one of the main challenges in endovascular treatment. The popliteal artery is subjected to biomechanical stress during knee motion, which makes stenting unappealing and often leads to worse clinical outcomes. This study aimed to describe the first follow-up outcomes of IVL in popliteal and infrapopliteal arterial disease. As in line with previous studies, no relevant procedural complications were found and the rate of bail-out stenting was only 12.5%. Moreover, in a complex patient population, this study demonstrated promising safety and efficacy outcomes. The comparison of IVL with angioplasty alone or other vessel preparation devices for popliteal and infrapopliteal arterial disease is warranted.

Abstract
Percutaneous deep venous arterialization (pDVA) is an important technique in the pursuit of limb salvage for a certain high-risk subset of patients with chronic limb-threatening ischemia (CLTI) considered to have "no option" owing to the lack of tibial or pedal targets for revascularization. pDVA seeks to establish an arteriovenous connection at the level of the tibial vessels, in addition to tibial and/or pedal venoplasty, to provide a pathway for arterial perfusion via the tibial and/or plantar venous system. A commercial system for pDVA exists; however, it is not yet approved by the U.S. Food and Drug Administration. In the present report, we detail a method of pDVA that uses commercially available devices for a patient with no-option CLTI related to Buerger disease.

Abstract
An increasing proportion of patients with chronic limb-threatening ischemia are older and have multiple comorbidities, including diabetes and renal failure. For those who are not candidates for a surgical bypass, this set of patients presents a challenge to vascular surgeons and interventionalists owing to the complex below-the-knee and increasingly below-the-ankle disease pattern that can fail traditional approaches for endovascular intervention. Two techniques, the retrograde pedal access and the pedal-plantar loop technique, can be useful in these settings and in skilled hands can be used safely, with a high technical success rate. In patients with chronic limb-threatening ischemia who are not candidates for a single-segment saphenous vein bypass, the retrograde pedal access technique can be used not only in the setting of failed antegrade treatment, but also primarily when faced with a difficult groin or as an adjunct during a planned antegrade-retrograde intervention. The pedal plantar loop technique allows for retrograde access to tibial vessels without retrograde vessel puncture and additionally offers the ability to treat the pedal-plantar arch, which may have added benefit in wound healing. We describe the tips and tricks for these two techniques used in our limb salvage practice.

Abstract
For patients with "no-option" chronic limb-threatening ischemia, a final attempt can be made for limb salvage in the form of percutaneous deep vein arterialization (pDVA). In the present study, we describe five cases of pDVA using a BeBack crossing catheter (Bentley InnoMed GmbH; previously, the GoBack crossing catheter; Upstream Peripheral Technologies). From November 2021 to July 2022, five patients underwent pDVA using the BeBack crossing catheter. The demographic data, procedural details, and patient outcomes were recorded. Successful vascular crossing was achieved in all five cases using the BeBack device. No surgical complications were encountered. The limb salvage rate was 60%, and the wound closure rate was 40%. No mortalities occurred during the follow-up period. The findings from the present study demonstrate that the use of the BeBack crossing catheter for pDVA is safe and feasible.

Abstract
We report on two venous arterialization (VA) techniques for treatment of CLTI in patients traditionally considered as having no treatment options for standard arterial endovascular or surgical bypass procedures. Screening and the preprocedural workup findings are outlined as deciding factors in determining a patient's fitness for the two techniques, with a focus on careful preprocedure arterial duplex ultrasound and assessment for vein suitability. Cardiac and infection screening are also factors in determining patient suitability for VA. In addition, radiographic assessment for the presence of medial artery calcification, which is used as a marker of technical difficulty and is a predictor of poor outcomes, is required. Ultimately, anatomic factors are used to determine the decision between hybrid superficial VA and or endovascular deep VA. Those with an occluded anterior tibial artery and suitable great saphenous vein are prioritized to hybrid superficial VA, and those with an occluded posterior tibial artery to endovascular deep VA. Both procedures are described in detail in this report of vascular and surgical techniques.

Abstract
OBJECTIVES The treatment for chronic limb-threatening ischemia (CLTI) has changed dramatically in the last few decades with a shift toward an endovascular-first approach and aggressive revascularization to achieve limb salvage. As the size of the CLTI population and intervention rates increase, patients will continue to experience technical failure (TF). Here, we describe the natural history of patients after TF of endovascular intervention for CLTI. METHODS We conducted a retrospective cohort study of patients with CLTI who attempted endovascular intervention or bypass at our multidisciplinary limb salvage center from 2013 to 2019. Patient characteristics were collected according to the Society for Vascular Surgery's reporting standards. Primary outcomes included survival, limb salvage, wound healing, and revascularization patency. Product-limit Kaplan-Meier estimated survival functions for these outcomes, and between-group comparisons were made using Mantel-Cox log-rank nonparametric tests. RESULTS We identified 242 limbs from 220 unique patients who underwent primary bypass (n = 30) or attempted endovascular intervention (n = 212) at our limb salvage center. Endovascular intervention was a TF in 31 (14.6%) limbs. After TF, 13 limbs underwent secondary bypass and 18 limbs were managed medically. Patients who experienced TF tended to be older (P < .001), male (P = .003), current tobacco users (P = .014), have longer lesions (P = .001), and have chronic total occlusions of target arteries (P < .001) as compared with those who experienced technical success. Furthermore, the TF group had worse limb salvage (P = .047) and slower wound healing (P = .028), but their survival was not different. Survival, limb salvage, and wound healing were not different in patients who received secondary bypass or medical management after TF. The secondary bypass group was older (P = .012) and had a lower prevalence of tibial disease (P = .049) than the primary bypass group and trended toward decreased survival, limb salvage, and wound healing (P = .059, P = .083, and P = .051, respectively). CONCLUSIONS Increased age, male sex, current tobacco use, longer arterial lesions, and occluded target arteries are associated with TF of endovascular intervention. Limb salvage and wound healing are relatively poor after TF of endovascular intervention, but survival appears comparable with patients who experience technical success. Secondary bypass may not always rescue patients after TF, though our sample size limits statistical power. Interestingly, patients who received a secondary bypass after TF trended toward decreased survival, limb salvage, and wound healing compared with primary bypass.

Abstract
Background: Frailty is a complex multisystem syndrome associated with increased comorbidity and decreased physiological reserve. There are associations between frailty and adverse outcome in surgical patients. Chronic limb threatening ischemia (CLTI) is increasingly prevalent, with a typically frail patient population. Existing frailty scoring systems focus on functional measures and do not reliably assess comorbidities. The present study aims to describe the prognostic value of multimodal frailty assessment in patients with CLTI. Patients and methods: Patients >50 years old admitted as an emergency with CLTI between May 2020 to June 2021 were included. Frailty was measured using Clinical Frailty Score (CFS), and comorbidities with American Society of Anesthiologists score (ASA). A composite score combining CFS and ASA was derived and the prognostic value compared with each component score. The primary outcome was overall survival. Results: There were 249 eligible patients, 53.4% (n=133) had CFS>4. The mean (95% CI) overall survival for the CFS>4 cohort was 15.9 (13.6-18.3) months vs. 28.5 (26.1-30.9) months for CFS≤4 cohort (p<0.001). Increasing CFS-ASA score was associated with inferior survival on univariate (HR=2.84, 95% CI [1.96-4.11], p<0.001) and multivariate (HR=1.78, 95% CI [1.20-2.64], p<0.01) analyses. ROC-analysis showed comparable prognostic value of CFS and CFS-ASA to predict one-year survival. Conclusions: Frailty is highly prevalent and a poor prognostic indicator in patients with CLTI admitted as an emergency. Our results suggest that incorporating assessment of comorbidities into frailty assessment may offer prognostic value, but comparable to existing clinical frailty assessment. Further work to identify patients with inferior prognosis is required.

Abstract
Chronic limb-threatening ischaemia (CLTI) is a severe form of peripheral arterial disease (PAD) and is associated with an increased risk of amputation, mortality, and significantly impaired quality of life. International guidelines recommend considering timely revascularisation and optimal medical therapy to improve limb perfusion in individuals with CLTI. The 2 primary revascularization approaches for CLTI are open bypass surgery (BS) and endovascular therapy (EV), however, there is currently no consensus on the best initial treatment strategy for CLTI, leading to uncertainty among clinicians. To shed light on this issue, 2 recent trials, namely best endovascular versus best surgical therapy in patients with CLI (BEST-CLI) and bypass versus angioplasty for severe ischaemia of the leg (BASIL-2), have tried to provide valuable insights. While a definitive conclusion on the optimal revascularisation approach is still pending, these trials offer immediate and clinically relevant information to the diabetic foot multidisciplinary team. The trials encompassed a distinct range of patient cohorts and included participants with varying degrees of medical and physical frailty. Taken together, their findings, highlight the need for an individualised revascularisation strategy which accounts for underlying comorbidities, risk factors, disease severity, availability of suitable bypass conduits, surgical risks, and timely access to procedures. Regardless of the chosen strategy, early referral of patients with diabetes and CLTI to a specialist team within a multidisciplinary environment is crucial. Comprehensive care should encompass essential elements such as adequate debridement, infection control, offloading, glycaemic control, smoking cessation, and patient education. By addressing these aspects, healthcare providers can optimise the management and outcomes for individuals with CLTI and diabetes.

Abstract
Objectives: To estimate the effectiveness of balloon aortic valvuloplasty (BAV) for severe aortic stenosis (SAS) in patients scheduled for open surgery for chronic limb-threatening ischemia. Materials and Methods: Clinical data of patients from 2012 to 2018 were retrieved and summarized. The early outcomes and survival after BAV and open bypass were retrospectively investigated. Results: BAV was performed on seven dialysis patients. One patient died of mesenteric infarction 3 days after BAV; however, six patients were able to undergo open bypass at an average of 10 days (7-19 days) after BAV. One patient died of hemorrhagic shock before the wound healed; five patients underwent limb salvage. Four of these five patients could not undergo surgical aortic open valve replacement owing to advanced age or poor cardiac function and died within 2 years. Only one patient who underwent radical surgery after a bypass survived more than 4 years. Conclusion: BAV enabled open surgery and limb salvage in patients with SAS. Although BAV alone cannot ensure long-term survival, the procedure will continue to be important as a bridge technique to radical surgery, such as transcatheter aortic valve implantation and aortic valve repair, which are often avoided owing to infection.

Abstract
INTRODUCTIO Frailty is a chronic condition with complex aetiology and impaired functional performance, which has been associated altered body composition and chronic inflammation. Chronic Limb Threatening Ischaemia (CLTI) carries significant morbidity and mortality and is associated with poor quality of life. The present study aims to examine these relationships and their prognostic value in patients with CLTI. METHODS Consecutive patients presenting as unscheduled admissions to a single tertiary centre with CLTI were included over a 12-month period. Frailty was diagnosed using the clinical frailty scale (CFS). Body composition was assessed using CT at the L3 vertebral level (CT-BC) to generate visceral and subcutaneous fat indices (VFI, SFI), skeletal muscle index (SMI), and skeletal muscle density (SMD). SMI and SMD were combined to form the CT-sarcopenia score (CT-SS). Systemic inflammation was assessed by the modified Glasgow Prognostic Score (mGPS). The primary outcome was overall mortality. RESULTS There were 190 patients included with a median (IQR) follow-up of 22 (6) months (range 15-32 months), and 79 deaths during the follow-up period. 100 patients (53%) had a CFS > 4. CFS > 4 (HR 2.14, 95% CI 1.25 - 3.66, p <0.01), CT-SS (HR 1.47, 95% CI 1.03 - 2.09, p <0.05), and mGPS (HR 1.54, 95% CI 1.11 - 2.13, p <0.01) were independently associated with increased mortality. CT-SS (OR 1.88, 95% CI 1.09 - 3.24, p < 0.01) was independently associated with CFS > 4. Patients with CT-SS 0 & CFS ≤4 had 90% (SE 5%) 1-year survival, compared with 35% (SE 9%) in patients with CT-SS 2 & CFS >4 (p <0.001). Patients with mGPS 0 & CFS ≤ 4 had 94% (SE 4%) 1-year survival compared with 44% (SE 6%) in the mGPS 2 & CFS > 4 subgroup (p <0.001). CONCLUSIONS Frailty assessed by CFS was associated with CT-BC. CFS, CT-SS and mGPS were associated with poorer survival in patients presenting as unscheduled admissions with CLTI. CT-SS and mGPS may contribute to part of frailty and prognostic assessment in this patient cohort.

Abstract
OBJECTIVE Despite societal guidelines that peripheral vascular intervention (PVI) should not be the first-line therapy for intermittent claudication, a significant number of patients will undergo PVI for claudication within 6 months of diagnosis. The aim of the present study was to investigate the association of early PVI for claudication with subsequent interventions. METHODS We evaluated 100% of Medicare fee-for-service claims to identify all beneficiaries with a new diagnosis of claudication from January 1, 2015 to December 31, 2017. The primary outcome was late intervention, defined as any femoropopliteal PVI performed >6 months after the claudication diagnosis (through June 30, 2021). Kaplan-Meier curves were used to compare the cumulative incidence of late PVI for claudication patients with early (≤6 months) PVI vs those without early PVI. A hierarchical Cox proportional hazards model was used to evaluate the patient- and physician-level characteristics associated with late PVIs. RESULTS A total of 187,442 patients had a new diagnosis of claudication during the study period, of whom 6069 (3.2%) had undergone early PVI. After a median follow-up of 4.39 years (interquartile range, 3.62-5.17 years), 22.5% of the early PVI patients had undergone late PVI vs 3.6% of those without early PVI (P < .001). Patients treated by high use physicians of early PVI (≥2 standard deviations; physician outliers) were more likely to have received late PVI than were patients treated by standard use physician of early PVI (9.8% vs 3.9%; P < .001). Patients who had undergone early PVI (16.4% vs 7.8%) and patients treated by outlier physicians (9.7% vs 8.0%) were more likely to have developed CLTI (P < .001 for both). After adjustment, the patient factors associated with late PVI included receipt of early PVI (adjusted hazard ratio [aHR], 6.89; 95% confidence interval [CI], 6.42-7.40) and Black race (vs White; aHR, 1.19; 95% CI, 1.10-1.30). The only physician factor associated with late PVI was a majority of practice in an ambulatory surgery center or office-based laboratory, with an increasing proportion of ambulatory surgery center or office-based laboratory services associated with significantly increased rates of late PVI (quartile 4 vs quartile 1; aHR, 1.57; 95% CI, 1.41-1.75). CONCLUSIONS Early PVI after the diagnosis of claudication was associated with higher late PVI rates compared with early nonoperative management. High use physicians of early PVI for claudication performed more late PVIs than did their peers, especially those primarily delivering care in high reimbursement settings. The appropriateness of early PVI for claudication needs critical evaluation, as do the incentives surrounding the delivery of these interventions in ambulatory intervention suites.

Abstract
OBJECTIVE Optimizing medical management and risk factor modification are underutilized strategies in patients with chronic limb threatening ischemia (CLTI), despite evidence of improved outcomes. The Vascular Quality Initiative (VQI) registry is a tool to improve quality of vascular care. In this study, we used the VQI to evaluate trends in medical management in CLTI patients undergoing peripheral vascular interventions (PVI), and the impact of changes in management on overall survival (OS), amputation-free survival (AFS) and limb salvage (LS). METHODS Patients undergoing index PVI for CLTI between 2012-2016, with at least 24-month follow-up were identified from the national VQI registry. Patient details including smoking status and medication use, OS, LS, and AFS were analyzed with linear-by-linear association, t-test and logistic regression. RESULTS 12,370 PVI were completed in 11,466 patients. There was a significant increase in infrapopliteal interventions (29.8% → 39.0%; P < .001) and PVI performed for tissue loss (TL) (59.1% → 66.5%; P < .001). The percentage of current smokers at time of PVI decreased (36.2% → 30.7%; P = .036). At discharge, statins were initiated in 25%, aspirin in 45% and P2Y12 therapy in 58% of patients not receiving these medications prior to PVI. Over the course of follow-up, dual antiplatelet (DAPT) (41.1% → 48.0%; P < .001), ACE-inhibitor (46.2% → 51.3%; P < .001), and statin (70.4% → 77.5%; P < .001) use increased. Combined DAPT, ACE-inhibitor and statin use increased from 33.6% → 39.6% (P=<.001). Significant improvement in 24-month OS and AFS was noted (OS, 90.9% → 93.7%; P = .002: AFS, 81.2% → 83.1%; P = .046) but not LS (89.6% → 89.0%; P = .83). Combined therapy with P2Y12 inhibitors, statins and ACE-inhibitors was an independent predictor of improved OS (HR 0.61; 0.39 - 0.96, P = .034). DAPT was independent predictor of improved LS (HR 0.83; 0.79 - 0.87, P < .007). CONCLUSION Antiplatelet, ACE-inhibitor and statin use increased over the study period and was associated with improved OS and AFS. Limb salvage trends did not change significantly over time, possibly due to inclusion of patients with higher disease burden or inadequate medical management. Medical management, although improved, remained far from optimal and represents an area for continued development.

Abstract
Recently, a new low-density lipoprotein apheresis device (Rheocarna®; Kaneka Corporation, Osaka, Japan), a blood purification therapy, was approved in Japan for managing chronic limb-threatening ischemia with refractory ulcers. Here, we describe a case of chronic limb-threatening ischemia that was treated with the Rheocarna. A 65-year-old Asian man with an ulcer on the right heel was admitted to our hospital. Angiography revealed chronic total occlusion with severe calcification of the anterior tibial, peroneal, and posterior tibial arteries. The patient underwent distal bypass of the saphenous vein; however, the bypass was occluded in the early postoperative period. The Rheocarna was used, and the ulcers improved significantly postoperatively. Although endovascular treatment was eventually performed on the occluded bypass graft to completely heal the ulcer, the Rheocarna could be an alternative treatment option in challenging cases of chronic limb-threatening ischemia.

Abstract
PURPOSE Transmetatarsal amputation (TMA) with primary closure has long been an option for limb salvage in patients with advanced chronic limb-threatening ischemia (CLTI) with extensive tissue loss of the forefoot. However, TMA healing and closure techniques are challenging, specifically in high-risk patients. Guillotine transmetatarsal amputations (gTMA) with staged closure may provide an alternative treatment in this population. We report long-term outcomes of such technique. MATERIALS AND METHODS A single-center retrospective cohort study of CLTI patients undergoing gTMA between 2017 and 2020 was performed. Limb salvage, wound healing, and survival rates were quantified using Kaplan-Meier (KM) analysis. Multivariate regression was used to identify the effect of patient characteristics on the outcomes. RESULTS Forty-four gTMA procedures were reviewed. Median follow-up was 381 (interquartile range [IQR], 212-539.75) days. After gTMA, 87.8% (n=36) of the patients were able to ambulate after a median interval of 2 (IQR, 1-3) days. Eventual coverage was achieved in a personalized and staged approach by using a combination of skin substitutes (88.6%, n=39) ± split thickness skin grafts (STSG, 61.4%, n=27). KM estimates for limb salvage, wound healing, and survival were 84.1%, 54.5%, and 88.6% at 1 year and 81.8%, 63.8%, and 84.1% at 2 years. Wound healing was significantly associated with STSG application (p=0.002, OR=16.5, 95% CI 2.87-94.81). CONCLUSION gTMA resulted in high limb salvage rates during long-term follow-up in CLTI patients. Adjunctive STSG placement may enhance wound healing at the gTMA site, thus leading to expedited wound closure. Surgeons may consider gTMA as an alternative to reduce limb loss in CLTI patients at high risk of major amputation. CLINICAL IMPACT Currently, the clinical presentation of CLTI is becoming more complex to deal with due to the increasing comorbidities as the society becomes older. The data shown in this article means for clinicians that when facing diffused forefoot gangrene and extensive tissue loss, limb preservation could still be considered instead of major amputation. Guillotine transmetatarsal amputations in the setting of an aggressive multidisciplinary group, can be healed by the responsibly utilization of dermal substitutes and skin grafts leading to the preservation of the extremity, allowing mobility, avoiding of sarcopenia, and decreasing frailty. This will equate to maintenance of independent living and preservation of lifespan.

Abstract
Background Endothelial colony forming cells (ECFCs), alone or in combination with mesenchymal stem cells, have been selected as potential therapeutic candidates for critical limb-threatening ischemia (CLTI), mainly for those patients considered as “no-option,” due to their capability to enhance revascularization and perfusion recovery of ischemic tissues. Nevertheless, prior to translating cell therapy to the clinic, biodistribution assays are required by regulatory guidelines to ensure biosafety as well as to discard undesired systemic translocations. Different approaches, from imaging technologies to qPCR-based methods, are currently applied. Methods In the current study, we have optimized a cell-tracking assay based on DiR fluorescent cell labeling and near-infrared detection for in vivo and ex vivo assays. Briefly, an improved protocol for DiR staining was set up, by incubation of ECFCs with 6.67 µM DiR and intensive washing steps prior cell administration. The minimal signal detected for the residual DiR, remaining after these washes, was considered as a baseline signal to estimate cell amounts correlated to the DiR intensity values registered in vivo. Besides, several assays were also performed to determine any potential effect of DiR over ECFCs functionality. Furthermore, the optimized protocol was applied in combination with qPCR amplification of specific human Alu sequences to assess the final distribution of ECFCs after intramuscular or intravenous administration to a murine model of CLTI. Results The optimized DiR labeling protocol indicated that ECFCs administered intramuscularly remained mainly within the hind limb muscle while cells injected intravenously were found in the spleen, liver and lungs. Conclusion Overall, the combination of DiR labeling and qPCR analysis in biodistribution assays constitutes a highly sensitive approach to systemically track cells in vivo. Thereby, human ECFCs administered intramuscularly to CLTI mice remained locally within the ischemic tissues, while intravenously injected cells were found in several organs. Our data corroborate the need to perform biodistribution assays in order to define specific parameters such as the optimal delivery route for ECFCs before their application into the clinic.

Abstract
Background Pathologic studies have shown that in patients with critical limb threatening ischaemia (CLTI) medial arterial calcifications are frequently found and may be responsible for aggravating the disease. These extensive calcifitcations are found not only in arteries of the leg but also in the coronary arteries and the aorta. The progression of these calcifications is fast and they stiffen the vessel wall and may thus increase the cardiovascular risk. Reduction of progression of calcification may not only reduce the burden of CLTI but may also reduce the high residual cardiovascular risk. Medial calcifications have been halted by etidronate in other trials. Its potential to reduce the burden from peripheral vascular disease in CLTI and residual cardiovascular risk remains to be established. Methods This is an investigator-initiated multicenter, double blind, placebo-controlled, randomized trial comparing the effects of etidronate versus placebo in patients with CLTI. Subjects will be randomized to either treatment with etidronate for 12 months (cyclical 20 mg/kg for 2 weeks on and 10 weeks off) orally or placebo for 12 months (in a similar routine). The primary endpoint is the change in arterial calcification as quantified by CT-scan. Secondary endpoints are the number of amputations above and below the ankle, mortality, number of vascular interventions and quality of life. Discussion Up to now, the inert end stage of vascular disease in patients with CLTI, has been considered calcification of vessel walls. We believe there is reason to reverse causation and hypothesize that calcification causes vascular disease. This reversal can be proven in a clinical trial if halting the calcification process improves the outcome of the patient. Therefore we use etidronate, a bisphosphate that has proven to stop the calcification in several rare monogenetic calcifying diseases. We aim to perform this mechanistic proof-of-concept study hopefully leading to a clinical outcome study later on.

Abstract
Background: The healing of foot wounds in patients with diabetes mellitus is frequently complicated by critical limb threatening ischemia (neuro-ischemic diabetic foot syndrome, DFS). In this situation, imminent arterial revascularization is imperative in order to avoid amputation. However, in many patients this is no longer possible (“too late”, “too sick”, “no technical option”). Besides conservative treatment or major amputation, many alternative methods supposed to decrease pain, promote wound healing, and avoid amputations are employed. We performed a narrative review in order to stress their efficiency and evidence. Methods: The literature research for the 2014 revision of the German evidenced-based S3-PAD-guidelines was extended to 2020. Results: If revascularization is impossible, there is not enough evidence for gene- and stem-cell therapy, hyperbaric oxygen, sympathectomy, spinal cord stimulation, prostanoids etc. to be able to recommend them. Risk factor management is recommended for all CLTI patients. With appropriate wound care and strict offloading, conservative treatment may be an effective alternative. Timely amputation can accelerate mobilization and improve the quality of life. Conclusions: Alternative treatments said to decrease the amputation rate by improving arterial perfusion and wound healing in case revascularization is impossible and lack both efficiency and evidence. Conservative therapy can yield acceptable results, but early amputation may be a beneficial alternative. Patients unfit for revascularization or major amputation should receive palliative wound care and pain therapy. New treatment strategies for no-option CLTI are urgently needed.

Abstract
(1) Background: While tibial bypass surgery still plays a role in the treatment of patients with chronic limb-threatening ischemia and diabetic foot syndrome; only a few centers have recorded considerable numbers of these conditions. The current study aimed to determine contemporary practice with special focus on the performance of extra-anatomic grafting to the infrapopliteal arteries. (2) Methods: A retrospective, single-center study included patients with tibial bypass grafts from 1 January 2008 to 31 December 2019. Primary endpoints were complication rate, graft patency, amputation, overall survival, and major adverse cardiac (MACE) or limb event (MALE). The cohort was stratified by extra-anatomic vs. anatomic position. (3) Results: A total of 455 patients (31% female) with Rutherford stage 4 (12.5%) and 5/6 (69.5%) were included (thereof, 19.5% had high amputation risk according to the Wound Ischemia Foot Infection score). Autologous reconstruction was performed in 316 cases, and prosthetic reconstruction in 131 cases, with a total of 51 (11.2%) extra-anatomic grafts. Early occlusion rate was 9.0% with an in-hospital overall mortality of 2.8%. The in-hospital rate of MACE was 2.4% and of MALE, 1.5%. After one, three and five years, the primary patency of venous bypasses was 74.5%, 68.6% and 61.7%, respectively. For prosthetic grafts, this was 55.1%, 46.0%, and 38.3%, respectively (p < 0.001). The patency of extra-anatomic prosthetic grafts performed significantly better compared with anatomically positioned prosthetic grafts (log-rank p = 0.008). In multivariate analyses, diabetes (hazard ratio, HR 1.314, CI 1.023−1.688, p = 0.032), coronary artery disease (HR 1.343, CI 1.041−1.732, p = 0.023), and dialysis dependency (HR 2.678, CI 1.687−4.250, p < 0.001) were associated with lower odds of survival (4) Conclusion: In this large, single-center cohort, tibial bypass surgery demonstrated satisfactory results with overall low perioperative complication rates and long-term patency rates of 60% and 38%, respectively. Extra-anatomic bypasses represent a feasible alternative to venous grafts in terms of patency. A tailored, patient-centered approach considering predictors such as diabetes, dialysis dependency, and coronary artery disease along with prediction models may further improve the long-term results in the future.

Abstract
BACKGROUND Patients with lower extremity wounds from diabetes mellitus or peripheral artery disease (PAD) have a risk of amputation as high as 25%. In patients with arterial disease, revascularization decreases the risk of amputation. We aimed to determine if the early assessment of arterial perfusion correlates with the risk of amputation. METHODS We retrospectively reviewed patients referred to the vascular clinic over 18 months with Rutherford Grade 5 and 6 chronic limb-threatening ischemia to determine if patients had a pulse exam done at the time the wound was identified and when ankle brachial index (ABI) testing to evaluate perfusion was performed. Kaplan Meier analysis was used to determine if the timing of ABI testing affected the time to revascularization, wound healing, and risk of amputation. RESULTS Ninety-three patients with lower extremity wounds were identified. Of these, 59 patients (63%) did not have a pulse exam performed by their primary care provider when the wound was identified. Patients were classified by when they underwent ankle brachial index testing to assess arterial perfusion. Twenty-four had early ABI (<30 days) testing, with the remaining 69 patients having late ABI testing. Patients in the early ABI group were more likely to have a pulse exam done by their PCP than those in the late group, 12 (50%) vs. 22 (32%), P = 0.03. Early ABI patients had a quicker time to vascular referral (13 days vs. 91 days, P < 0.001). Early ABI patients also had quicker times to wound healing than those in the late group (117 days vs. 287 days, P < 0.001). Finally, patients that underwent early ABI were less likely to require amputation (Fig. 1), although this did not reach statistical significance (P = 0.07). CONCLUSIONS Early ABI testing expedites specialty referral and time to revascularization. It can decrease the time to wound healing. Larger cohort studies are needed to determine the overall effect of early ABI testing to decrease amputation rates.

Abstract
OBJECTIVE To evaluate the results of endovascular surgery in patients with chronic limb-threatening ischemia (CLTI) with infrainguinal arterial disease GLASS III. MATERIAL AND METHODS Treatment outcomes were analyzed for the period 2017-2018. Inclusion criteria were age over 18 years, CLTI, extended (>20 cm) stenosis de novo and occlusion of femoropopliteal segment (FPS) combined with occlusive lesion of tibial arteries. We analyzed 147 patients divided into 2 groups depending on stenting strategy. FPS-1-TA included 53 patients who underwent angioplasty (± stenting) of femoropopliteal arteries and lower leg arteries resulted at least one patent tibial artery. FPS-2-TA enrolled 94 patients who underwent angioplasty of femoropopliteal arteries and lower leg arteries resulted ≥2 patent tibial arteries. Mean age was 71.0±9.8 years. There were 75 men. Demographics and clinical characteristics of patients were similar. RESULTS Technical success rate was 100%. Mean length of stenting was 203 ± 99 mm. Occlusion of all 3 leg arteries correlated with high incidence of femoropopliteal stenting. In the FPS-1-TA group, stents were implanted in 39 patients, in the FPS-2-TA group - in 71 patients (73.6% and 75.5%, respectively, p=0.8). Braided nitinol stents were used for stenting of the lower third of superficial femoral artery and p1-p3 segments. Mean follow-up period was 22.6±1.1 months. Two-year results were not age-specific in our study. Kaplan-Meier overall survival, freedom from amputation and amputation-free survival for the entire sample were 79.6%, 81.0%, and 66.7%, respectively. We compared these values in both groups using Mantel-Cox log-rank test and obtained significant differences (67.9% vs 86.2%, p=0.004; 64.2% vs 90%, p<0.0001; 47.2% vs 77.7%, p<0.0001, respectively). CONCLUSION Our results are comparable with literature data regarding freedom from amputation and amputation-free survival. We obtained significant differences in overall survival and freedom from amputation depending on endovascular strategy for tibial arteries. Correction of distal vessels with recanalization of at least two tibial arteries is advisable for endovascular treatment of diffuse complex lesions.

Abstract
Chronic limb-threatening ischemia (CLTI) is prevalent and associated with morbidity and mortality. The published research concerning CLTI therapeutics is evolving. The goals of this review are to: 1) summarize the endpoints that are being used in trials assessing interventions for patients with CLTI; and 2) review gaps and discrepancies in current outcome definitions. A search was conducted of the PubMed database and ClinicalTrials.gov to identify studies published between January 2000 and March 2020 that evaluated treatment options for patients with CLTI. Meta-analyses, case series, case reports, abstracts, and expert opinion were excluded. Forty-nine studies (n = 11,667) were identified that fulfilled the inclusion criteria. Most trials reported clinical outcomes (mortality, 69.4%; limb events, 87.8%; target lesion revascularization, 83.7%). Mean follow-up duration was 23.7 months. In investigational device exemption trials, total follow-up and follow-up to primary outcomes were discordant (12 months vs 6 months; P = 0.0018). Hemodynamic testing was reported in 71.4%, usually ankle-brachial index. Patency was assessed in 89.8% of trials; ultrasound was used in 65.3% and invasive angiography in 85.7%, at baseline and/or during follow-up. Wound assessment was performed in 49.0% of studies, qualitative in 28.6% and quantitative in 20.4%. Finally, quality of life assessment was performed in 55% of studies. Definitions for many outcomes varied across studies. Consensus regarding which outcomes to study, uniform definitions, and optimal methods to measure some of these outcomes are yet to be established. A comprehensive effort by all stakeholders is needed to move the field of CLTI forward.

Abstract
Objective: The 2020 Global Vascular Guidelines aim at improving decision making in Chronic Limb-Threatening Ischemia (CLTI) by providing a framework for evidence-based revascularization. Herein, the Global Limb Anatomic Staging System (GLASS) serves to estimate the chance of success and patency of arterial pathway revascularization based on the extent and distribution of the atherosclerotic lesions. We report the preliminary feasibility results and observer variability of the GLASS. GLASS is a part of the new global guideline and posed as a promising additional tool for EBR strategies to predict the success of lower extremity arterial revascularization. This study reports on the consistency of GLASS scoring to maximize inter-observer agreement and facilitate its application. Methods: GLASS separately scores the femoropopliteal (FP) and infrapopliteal (IP) segment based on stenosis severity, lesion length and the extent of calcification within the target artery pathway (TAP). In our stepwise approach, we used two angiographic datasets. Each following step was based on the lessons learned from the previous step. The primary outcome was inter-observer agreement measured as Cohen’s Kappa, scored by two (step 1 + 2) and four (step 3) blinded and experienced observers, respectively. Steps 1 (n = 139) and 2 (n = 50) were executed within a dataset of a Dutch interventional RCT in CLTI. Step 3 (n = 100) was performed in randomly selected all-comer CLTI patients from two vascular centers in the United States. Results: In step 1, kappa values were 0.346 (FP) and 0.180 (IP). In step 2, applied in the same dataset, the use of other experienced observers and a provided TAP, resulted in similar low kappa values 0.406 (FP) and 0.089 (IP). Subsequently, in step 3, the formation of an altered stepwise approach using component scoring, such as separate scoring of calcification and adding a ruler to the images resulted in kappa values increasing to 0.796 (FP) and 0.730 (IP). Conclusion: This retrospective GLASS validation study revealed low inter-observer agreement for unconditioned scoring. A stepwise component scoring provides acceptable agreement and a solid base for further prospective validation studies to investigate how GLASS relates to treatment outcomes.

Abstract
OBJECTIVE The use of drug coated balloon (DCB) for angioplasty has shown superior efficacy against plain balloons for treating complex infrainguinal arterial disease. We report and compare the clinical outcomes following application of DCB(Paclitaxel) and plain angioplasty (POBA) in our tertiary care centre. METHODS A retrospective, single centre analysis of 301 patients with chronic limb-threatening ischemia involving the infrainguinal segment was conducted between September 2014 and September 2018, after approval from the Institutional review board. We analyzed clinical outcomes by measuring postoperative ABI improvement, restenosis requiring reintervention procedure, minor and major amputations at the end of 18 months. . To find the association between the group variables (POBA and DCB) and other risk variables, Chi-square test/Fisher's exact test was used. Multivariable logistic regression analysis was used. RESULTS Patients who underwent treatment with plain balloon (POBA) and DCB(Paclitaxel) angioplasty were 246(81.7%) and 55(18.3%) respectively. Our study group was predominantly male (Male: Female = 6.7:1), most patients were more than 50 years of age (n = 251, 83.4%). Smoking (n = 199, 66.1%) and diabetes (n = 210, 69.8%) were the most common atherosclerotic risk factors. Postoperative Ankle Brachial Pressure Index (ABI) improvement were similar in both groups (POBA = 57.7%; DCB = 69.8%; p = 0.103). Minor and major amputations following POBA were 26% and 22%; and DCB were 12.7% and 16.4% respectively. Re-stenosis requiring a re-interventional procedure within 18 months was 15%, (n = 37) following POBA; and 12.7% (n = 7) following DCB (p = 0.661). CONCLUSIONS This retrospective study shows similar clinical limb related outcomes following POBA and DCB at 18 months. However, our comparative analysis between the POBA and DCB groups was totally unadjusted and not adjusted for common confounders such as age and sex. Hence, for one to draw definitive conclusions leading to changes in clinical practice; a randomized, prospective study with a larger patient cohort is needed.

Abstract
BACKGROUND Negative pressure wound therapy (NPWT) has been established over years for treatment of chronic and complex wounds. OBJECTIVE Aim of this study was to investigate the effect NPWT on the microperfusion. METHODS Prospective single centre analysis of patients treated with NPWT due to acute (ACUTE) wounds after fasciotomy or patients with chronic wounds (CHRONIC) due to a chronic limb threatening ischemia was performed. NPWT was conducted through a three days sequence with a negative pressure of -120 mmHg. Before after and during the entire period of therapy the microperfusion was assessed (O2C™, LEA Medizintechnik). RESULTS Comparison of the perfusion values of 28 patients (CHRONIC/ACUTE 5/23, women/men 8/20) before and after the NPWT sequence showed a non-significant improvement in the CHRONIC group (supine position: p = 0.144, elevated position p = 0.068) and a significant decrease in the ACUTE group (supine position p = 0.012, elevated position p = 0.034). This effect could also been demonstrated during the NPWT over time (CHRONIC: supine position: p = 0.320, elevated position: p = 0.053, ACUTE: supine position: p = 0.021, elevated position: p = 0.012). CONCLUSION Microperfusion measurements showed alterations and differences in wound bed perfusion of acute and chronic wounds; acute wounds tended to a decrease of blood flow, whereas this effect was not seen in chronic wounds in peripheral artery disease.

Abstract
BACKGROUND There is an increasing incidence of peripheral arterial disease (PAD). The most common symptomatic presentation of PAD is intermittent claudication (IC), reproducible leg pain with ambulation. The progression of symptoms beyond IC is rare, and a nonprocedural approach of smoking cessation, supervised exercise therapy, and best medical therapy can mitigate progression of IC. Despite the lack of limb- or life-threatening sequelae of IC, invasive treatment strategies of IC have experienced rapid growth. Within our health care system, PAD is treated by multiple disciplines with varying practice patterns, providing an opportunity to investigate the progression of IC based on treatment strategy. This study aims to compare PAD progression and amputation in patients with IC with and without revascularization. METHODS This institutional review board-approved, single institute retrospective study reviewed all patients with an initial diagnosis of IC between June 11, 2003, and April 24, 2019. Revascularization was defined as endovascular or open. Time to chronic limb-threatening ischemia (CLTI) diagnosis and amputation were stratified by revascularization status using the Kaplan-Meier method. The association between revascularization status and each of CLTI progression and amputation using multivariable Cox regression, adjusting for demographic and clinical potential confounding variables was assessed. RESULTS We identified 1051 patients who met the inclusion criteria. Of these patients, 328 had at least one revascularization procedure and 723 did not. The revascularized group was younger than the nonrevascularized group (60.3 years vs 62.1 years; P = .013). There was no significant difference in sex or comorbidities in the two groups other than a higher rate of diabetes mellitus type 2 (32.3% vs 16.3%; P < .001) and COPD (4.3% vs 1.7%; P = .017) in the revascularized group. Multivariable Cox regression found revascularization of patients with IC to be significantly associated with the progression to CLTI (hazard ratio, 2.9; 95% confidence interval, 2.0-4.2) and amputation (hazard ratio, 4.5; 95% confidence interval, 2.2-9.5). These findings were also demonstrated in propensity-matched cohorts of 218 revascularized and 340 nonrevascularized patients. CONCLUSIONS Revascularization of patients with IC is associated with an increased rate of progression to CLTI and increased amputation rates. Given these findings, further studies are required to identify which, if any, patients with IC benefit from revascularization procedures.

Abstract
The publication of the Global Vascular Guidelines in 2019 provide evidence-based, best practice recommendations on the diagnosis and treatment of chronic limb-threatening ischemia (CLTI). Certainly, the multidisciplinary team, and more specifically one with collaborating podiatrists and vascular specialists, has been shown to be highly effective at improving the outcomes of limbs at risk for amputation. This article uses the Guidelines to answer key questions for podiatrists who are caring for the patient with CLTI.

Abstract
OBJECTIVE The aim was to evaluate the utility of frailty, as defined by the modified Frailty Index-1 1 (mFI-11) on predicting outcomes following endovascular revascularisation in Asian patients with chronic limb-threatening ischaemia (CLTI). METHODS CLTI patients who underwent endovascular revascularisation between January 2015 and March 2017 were included. Patients were retrospectively scored using the mFI-11 to categorise frailty as low, medium or high risk. Observed outcomes included 30-day complication rate and unplanned readmissions, 1-, 6- and 12-month mortality, and ambulation status at 6- and 12 months post-intervention. RESULTS A total of 233 patients (250 procedures) were included; 137 (58.8%) were males and the mean age was 69.0 (±10.7) years. 202/233 (86.7%) were diabetic and 196/233 (84.1%) had a prior diagnosis of peripheral arterial disease (PAD). The mean mFI-11 score was 4.2 (±1.5). 28/233 (12.0%), 155/233 (66.5%), and 50/233 (21.5%) patients were deemed low (mF-11 score 0-2), moderate (mFI-11 score 3-5) and high (mFI-11 score 5-7) frailty risk, respectively. High frailty was associated with an increased 12-month mortality (OR 8.54, 95% CI 1.05-69.5; p = 0.05), 30-day complication rate (OR 9.41, 95% CI 2.01-44.1; p < 0.01) and 30-day unplanned readmission (OR 5.06, 95% CI 1.06-24.2; p = 0.04). Furthermore, a high score was associated with a significantly worse 6- (OR 0.320, 95% CI 0.120-0.840; p = 0.02) and 12-month (OR 0.270, 95% CI 0.100-0.710; p < 0.01) ambulatory status. CONCLUSION The mFI-11 is a useful, non-invasive tool that can be readily calculated using readily available patient data, for prediction of medium-term outcomes for Asian CLTI patients following endovascular revascularisation. Early recognition of short- and mid-term loss of ambulation status amongst high-frailty patients in this challenging cohort of patients could aid decision-making for whether a revascularisation or amputation-first policy is appropriate, and manage patient and caregiver expectations on potential improvement in functional outcome.

Abstract
Recently, Society for Vascular Surgery guideline recommends evaluating anatomic pattern with use of Global Limb Anatomic Staging System (GLASS) in Chronic Limb-Threatening Ischemia (CLTI) patients. The aim of this study is to validate GLASS stage into CLTI patients on hemodialysis (HD) and investigate the impact of GLASS stage to wound healing and amputation-free survival (AFS). Between April 2009 and March 2018, we performed EVT for 154 limbs in CLTI patients on HD. GLASS was defined as femoropopliteal (FP) and infrapopliteal (IP) segments separately graded (0-4), then combined into three GLASS stages for the limb (I-III). We divided them into three GLASS stages with using this system. We compared the clinical outcomes between three groups (GLASS I, GLASS II, and GLASS III). Patient characteristics were almost similar between the three groups. Lesion characteristics was more complex and the rate of success was lower in GLASS III. Cox regression multivariate analysis revealed that diabetes mellitus (HR 2.4, 95% CI 1.37-4.01, p < 0.01) and WIfI high (HR 2.3, 95% CI 1.04-6.01, p = 0.04) were the predictors of non-wound healing, whereas age (HR 1.6, 95% CI 1.09-2.29, p = 0.01), WIfI clinical stage 4 (HR 2.4, 95% CI 1.30-4.36, p < 0.01), and non-ambulatory status (HR 2.0, 95% CI 1.17-3.29, p = 0.01) were the predictors of AFS. GLASS stage in CLTI patient on HD could not predict wound healing, and AFS in this study.

Abstract
OBJECTIVE Angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) reduce the risk of cardiovascular events in patients with peripheral artery disease. However, their effect on limb-specific outcomes is unclear. The objective of this study was to assess the effect of ACE inhibitors/ARBs on limb salvage (LS) and survival in patients undergoing peripheral vascular intervention (PVI) for chronic limb-threatening ischemia (CLTI). METHODS The Vascular Quality Initiative registry was used to identify patients undergoing PVI for CLTI between April 1, 2010, and June 1, 2017. Patients with complete comorbidity, procedural, and follow-up limb and survival data were included. Propensity score matching was performed to control for baseline differences between the groups. LS, amputation-free survival (AFS), and overall survival (OS) were calculated in matched samples using Kaplan-Meier analysis. RESULTS A total of 12,433 limbs (11,331 patients) were included. The ACE inhibitors/ARBs group of patients had significantly higher prevalence of coronary artery disease (31% vs 27%; P < .001), diabetes (67% vs 57%; P < .001), and hypertension (94% vs 84%; P < .001) and lower incidence of end-stage renal disease (7% vs 12%; P < .001). Indication for intervention was tissue loss in 64% of the ACE inhibitors/ARBs group vs 66% in the no ACE inhibitors/ARBs group (P = .005). Postmatching survival analysis at 5 years showed improved OS (81.8% vs 79.9%; P = .01) and AFS (73% vs 71.5%; P = .04) with ACE inhibitors/ARBs but no difference in LS (ACE inhibitors/ARBs, 88.3%; no ACE inhibitors/ARBs, 88.1%; P = .56). After adjustment for multiple variables in a Cox regression model, ACE inhibitors/ARBs were associated with improved OS (hazard ratio, 0.89; 95% confidence interval, 0.80-0.99; P = .03) and AFS (hazard ratio, 0.92; 95% confidence interval, 0.84-0.99; P = .04). CONCLUSIONS ACE inhibitors/ARBs are independently associated with improved survival and AFS in patients undergoing PVI for CLTI. LS rates remained unaffected. Further research is required to investigate the use of ACE inhibitors/ARBs in this population of patients, especially CLTI patients with other indications for therapy with ACE inhibitors/ARBs.

Abstract
BACKGROUND Endovascular therapy is often the preferred first treatment option for chronic limb threatening ischemia (CLTI) patients. Drug coated balloons (DCB) reduce restenosis rates compared to percutaneous transluminal angioplasty (PTA), however DCB use has not been studied systematically in patients with CLTI. Thus, the optimal treatment option for these complex lesions remains controversial. METHODS We report on 327 patients with CLTI treated either with DCB (n = 105) or non-DCB (n = 222) for femoropopliteal disease. Data were retrieved from the Excellence in Peripheral Artery Disease (XLPAD) registry (NCT01904851). Two DCB types were used at the discretion of the operator: Lutonix® (BARD Peripheral Vascular, Inc., Tempe, AZ, USA) and IN.PACT AdmiralTM (Medtronic, Santa Rosa, CA, USA). Odds ratios and the respective 95% confidence interval were synthesized to examine the association between the two groups in terms of all-cause mortality, target limb repeat endovascular or surgical revascularization, target vessel revascularization (TVR), major and minor amputation at 12 months of follow up. RESULTS The mean lesion length was 150.0 mm (SD:123.2) and 151.2 mm (SD:108.3) for the DCB and non-DCB group respectively. No difference between the two groups was detected in terms of all-cause mortality (2.86%vs2.7%,p = .94), target limb repeat endovascular or surgical revascularization (16.19%vs12.61%,p = .25), TVR (16.19%vs.11.71%,p = .26) or minor amputation (15.24%vs10.81%,p = .25) at 12 months of follow up. Although a higher incidence of 12 months major amputation was observed in the DCB group (11%vs.4%,p = .01), after adjusting for several risk factors the odds of major amputation were not statistically different between the DCB and non-DCB groups (OR:1.54;95%CI:0.53-4.51;p = .43). CONCLUSIONS Both DCB and non-DCB strategies are effective modalities for revascularization of patients with CLTI. No differences were identified between the DCB and non-DCB group in terms of late outcomes during 12 months of follow up.
