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.

Abstract
PURPOSE OF REVIEW This paper provides a concise update on the management of peripheral artery disease (PAD). RECENT FINDINGS PAD continues to denote a population at high risk for mortality but represents a threat for limb loss only when associated with foot ulcers, gangrene, or infections. Performing either angiogram or non-invasive testing for all patients with foot ulcers, gangrene, or foot infections will help increase the detection of PAD, and refined revascularization strategies may help optimize wound healing in this patient group. Structured exercise programs are becoming available to more patients with claudication as methods to improve adherence to community-based exercise programs will improve. Finally, ensuring more patients with PAD receive aspirin therapy and statins may improve long-term survival, while further research will help determine if adding newer antiplatelet or anticoagulant medications may reduce leg amputations in selected patients. Clinicians should have a low threshold to obtain an angiogram and to pursue revascularization in patients with foot ulcers, gangrene, or foot infections. In patients with claudication, clinicians should maximize the benefits derived from exercise therapy and medical management before offering percutaneous or surgical revascularization.

Abstract
There is significant variability and equipoise in the management of critical limb ischemia (CLI). The Best Endovascular vs Best Surgical Therapy in Patients with Critical Limb Ischemia (BEST-CLI) trial, funded by the National Heart, Lung, and Blood Institute, is a prospective, open label, multicenter, multispecialty randomized controlled trial designed to compare treatment efficacy, functional outcomes, cost-effectiveness, and quality of life for 2100 patients suffering from CLI. BEST-CLI is enrolling those patients who are determined to be candidates for open surgical or endovascular revascularization and is designed to be comprehensive, pragmatic, and balanced. Enrollment is occurring at >130 sites across the world, and BEST-CLI is nearing the finish line. Although the trial has encountered a number of obstacles, they are being successfully navigated. This trial promises to establish an evidence-based standard of care in the management of this population of vulnerable patients.

Abstract
Lower extremity critical limb ischemia (CLI) represents symptoms related to end-stage atherosclerotic peripheral arterial disease manifested by rest pain and tissue loss. It is associated with increased risk of limb amputation and cardiovascular-related mortality. The prevalence and cost of CLI are expected to increase with both the aging of the U.S. population and continued influence of smoking and diabetes. Treatments encompass measures to reduce cardiovascular risk and preserve limb viability. Despite increasing popularity of endovascular modalities, revascularization with either surgical bypass or endovascular intervention is the cornerstone of therapy. Adequate Level I data to guide decisions regarding optimal strategies to treat CLI, particularly in patients who are candidates for both open and percutaneous approaches, are currently lacking. Ongoing randomized controlled trials aim to resolve the clinical equipoise.

Abstract
BACKGROUND The objective of this study was to assess the ability of a novel, automated Conformité Européenne marked vascular early warning system (VEWS) device to detect peripheral arterial disease in patients with incompressible ankle arteries and non-measurable ankle brachial pressure index (ABPI) secondary to diabetes. METHODS Recruited patients had diabetes, recent magnetic resonance angiography evidence of peripheral arterial disease (PAD), and incompressible vessels on ABPI. VEWS indices of each leg were automatically calculated by using optical infrared and red sensors applied to the foot, with readings obtained with the subject's leg both flat and elevated. Indices <1.03 and ≤0.94 were considered upper and lower diagnostic cutoff limits for PAD. Bollinger scores were calculated from the magnetic resonance angiography. A Best Bollinger Score (BBS) of <4 was defined as no significant PAD. RESULTS All patients had tissue loss. Per protocol analysis of 28 limbs in 14 patients: VEWS had a sensitivity of 94% and specificity 20% for the detection of PAD at <1.03 cutoff and sensitivity 89% and specificity 80% at ≤0.94 cutoff. There was a good correlation between the VEWS index and BBS (-0.637; P = 0.0003). CONCLUSION VEWS is a safe, simple-to-use, promising tool to assist in the diagnosis of PAD in patients with incompressible vessels due to diabetes.

Abstract
The treatment of chronic total occlusions (CTO) in patients with peripheral arterial disease (PAD) is a complex topic with multiple treatment techniques and treatment strategies. The interventionalist treating patients with PAD should have both a defined treatment algorithm and multiple techniques available for crossing these challenging lesions. This article will cover techniques for treating CTOs and provide an overview of current available evidence.

Abstract
Objective: This population-based retrospective cohort study investigates long-term results of femoropopliteal bypass and femoropopliteal endovascular intervention (PTA) in patients with critical ischemia, with focus on limb salvage and amputation-free survival. Methods: All patients who underwent femoropopliteal bypass or femoropopliteal PTA for critical ischemia without other simultaneous intervention between 1999 and 2013 were included. Stratification was according to treatment modality and symptoms, rest pain, or ischemic ulcer/gangrene. We assessed technical success, 30-day complications, length of stay, recurrent interventions, limb salvage, survival, and amputation-free survival in all patients. Results: We identified 292 operations in 264 patients, 140 bypass and 152 PTA. In 32 PTA cases, the patients were explicitly deemed unfit for bypass surgery. This group had significantly inferior technical success and limb salvage ( P = .00). In other patients, technical success was 96% for bypass and 93% for PTA, while limb salvage after 5 years was 78% for bypass and 81% for PTA. Reoperation for local complications was performed in 16% after bypass and 2% after PTA ( P = .00). Mean length of stay was 8 days after bypass and 1.9 days after PTA ( P = .00). Conclusions: Long-term follow-up showed similar technical success and good limb salvage for both PTA and bypass patients in this clinical cohort. Patients who were unfit for bypass surgery had significantly inferior technical success and limb salvage. PTA was associated with shorter hospital stay and fewer reoperations for local complications. The findings support a PTA first strategy in all cases where technical success is likely.

Abstract
Objectives Readmissions to hospital after surgical procedures are considered as reflective of poor quality of healthcare provided during the index hospitalization and are associated with increased costs of healthcare. Aortoiliac occlusive disease represents an aggressive form of atherosclerotic disease and has been traditionally treated with open surgical bypasses. Endovascular interventions for aortoiliac occlusive disease are associated with comparable outcomes to open surgical procedures. The purpose of this study is to review the factors associated with hospital readmission after aortoiliac endovascular interventions. Methods The 2015 procedure targeted American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database and general and vascular surgery NSQIP participant user file (PUF) were used for this analysis. Patient, diagnosis and procedure characteristics of patients undergoing aortoiliac endovascular interventions were reviewed. Bivariate analysis was used to identify the relationship between the independent variables and 30-day readmission. The significant variables from the bivariate analysis were used to generate a multivariable logistic regression model. The predicted probability of readmission was calculated. Results Out of 823 patients, 86 were readmitted. Readmission was related to the principal procedure in 48 (73.9%) patients. A total of 61 (7%) patients underwent an unplanned operation within 30 days after the index procedure. A multivariable logistic regression model identified the following variables to be significantly associated with 30-day risk of readmission: the use of pre-procedural beta blocker (OR = 2.06, 95% CI = 1.23 - 3.45, P < 0.01), external/internal iliac intervention (OR = 1.95, 95% CI = 1.18 - 3.20, P <0.01), critical limb ischemia (OR = 1.80, 95% CI = 1.10 - 2.94, P <0.05), and unplanned return to the operating room (OR = 11.65, 95% CI = 6.35 - 21.35, P <0.01). The predicted probability of readmission was as follows: 5.5% for critical limb ischemia, 5.9% for external iliac artery angioplasty/stenting, 6.2% for preoperative beta blockers, 17.7% for patients with cardiac arrest, 27% for unplanned return to the operating room, and 94.7% for patients with all of these risk factors. Conclusion Readmissions after endovascular interventions for severe atherosclerotic disease can be used as a quality metric. Several factors place a patient at a high risk for readmission. Unplanned return to the operating room, cardiac arrest, preoperative beta blockers, location of disease, and preoperative symptoms are independent risk factors for hospital readmission. Unplanned return to the operating room is associated with 11.65-fold increase in the risk of hospital readmission.

Abstract
The optimal approach for repeat revascularization after failed endovascular intervention for critical limb ischemia (CLI) is unclear. This study compared major adverse limb events (MALEs) and major adverse cardiac events (MACEs) between lower extremity bypass (LEB) and repeat endovascular intervention (REI) in patients with prior failed ipsilateral endovascular intervention. American College of Surgeons National Surgical Quality Improvement Program database identified patients undergoing LEB and endovascular intervention for CLI from 2011 to 2014. We compared REI to LEB with single-segment saphenous vein (LEB-SV) and LEB alternative conduit (LEB-alt). Primary outcomes were 30-day MALE and MACE. Multivariate analysis identified independent predictors of MALE and MACE. A total of 1567 revascularizations were performed after failed ipsilateral endovascular intervention (REI: 683 [43.5%], LEB-SV: 570 [36.4%], LEB-alt: 314 [20.0%]). There were 994 and 573 suprageniculate and infrageniculate revascularizations, respectively. Major adverse cardiac events were significantly lower after REI compared to LEB (REI: 15 [2.2%], LEB-SV: 33 [5.8%], LEB-alt: 21 [6.7%], P < .001). Major adverse limb event were not different between groups ( P = .99). In patients with CLI presenting after failed endovascular intervention, REI is associated with lower MACE without an increased risk of MALE compared to LEB. When the anatomy is amenable, REI should be considered a less morbid first option.

Abstract
BACKGROUND Based on prospective vein bypass trials for lower leg ischemia, objective performance goals (OPG) were established by the Society for Vascular Surgery (SVS) and are used as a benchmark tool for open and endovascular treatments. This study aims to analyze OPG of all patients with critical limb ischemia (CLI) treated by open revascularization techniques at a tertiary care facility in routine practice. METHODS From January 2005 to March 2013, 315 patients (mean age 72 years) with CLI were retrospectively included in this study. Inclusion criteria were patients with Fontaine stage III and IV, realized revascularization with open surgical procedures (bypass grafting or endarterectomy), or hybrid method (open + endovascular). Exclusion criteria were primary major amputations, patients with revascularization treatments of the index leg within the last 3 months, and missing aftercare. Primary end point was "amputation-free survival" (AFS), and secondary end point was "freedom from major adverse limb event + perioperative death (30 days)" (MALE + POD) according to the SVS. The technical end point was primary patency. Mean follow-up was 34 months. The following variables were studied: clinical stage (Fontaine), previous interventions, bypass material used, and site of the distal anastomosis. The statistical evaluation and preparation was carried out using the Kaplan-Meier estimator and the log-rank test. A multivariate analysis was performed using the Cox proportional hazards model. A P value ≤0.05 was considered to be statistically significant. RESULTS A total of 128 patients (31%) fulfilling the adjusted SVS OPG criteria showed significantly better results for AFS, MALE + POD, and primary patency (P = 0.013, P = 0.015, P = 0.002, respectively). Regarding the AFS (1 year: 74%), multivariate analysis displayed significant worse results for patients with end-stage renal disease (hazard ratio [HR] 2.90, 95% confidence interval [CI] 1.83-4.60, P < 0.001) and Fontaine stage IV (HR 1.69, 95% CI 1.11-2.57, P = 0.015). Regarding MALE + POD (1 year: 64%), male patients (HR 0.64, 95% CI 0.46-0.90, P = 0.011) showed a significantly better outcome and patients without previous interventions of the index leg (HR 1.51, 95% CI 1.09-2.09, P = 0.013) showed a significantly worse outcome. CONCLUSIONS In this study, we were able to show that it is possible to reach the efficacy of OPGs set by SVS in a surgically treated all-comers cohort of CLI patients. Nevertheless, patients who did not fulfill the SVS OPG criteria showed significantly worse results for AFS and MALE + POD.

Abstract
OBJECTIVE/BACKGROUND Lower limb peripheral arterial disease (PAD) is becoming increasingly common. Lower limb perfusion, as determined by the ankle brachial pressure index (ABPI), is a recognised predictor of overall mortality. The increasing role of non-invasive imaging in patient assessment may aid in the ability to predict poor patient outcomes. METHODS This study included all patients undergoing a lower limb arterial duplex over a period of 20 months. The site and burden of atherosclerosis within the lower limb was determined using the well validated Bollinger score. Patient demographic data were also collated. The primary outcome measure was all cause mortality. RESULTS A total of 678 patients were included (median age 74 years). The overall median follow up period was 69.9 months. Of these, 307 patients reached the primary end point, which was death. Independent predictors of all cause mortality included total Bollinger score (odds ratio [OR] 1.11, 95% confidence interval [CI] 1.05-1.18 [p < .001]; OR per 10 points), femoropopliteal Bollinger score (OR 1.34, 95% CI 1.11-1.08 [p = .05]; OR per 10 points), and crural Bollinger score (OR 1.03, 95% CI 1.01-1.03 [p = .03]). There was also a significant association between mortality and age, a prior history of ischaemic heart disease, a history of congestive cardiac failure and chronic renal failure (chronic kidney disease ≥ 3). Statin and antiplatelet therapy were protective. CONCLUSION This contemporary study confirms poor long-term outcomes still exist in patients with PAD. The site and severity of lower limb atherosclerosis are independent predictors of long-term mortality.

Abstract
PURPOSE OF REVIEW This review summarizes the risks of lower extremity amputation associated with critical limb ischemia (CLI) and discusses current therapies that can prevent amputation in CLI. RECENT FINDINGS CLI remains an under-recognized condition associated with high rates of major amputation and disparities in care. Optimal medical therapy can reduce the risk of major adverse cardiovascular and limb events, but revascularization combined with close wound care remains the cornerstone of amputation prevention. Endovascular revascularization has become more common over time and has been associated with a reduction in amputation rates. Ongoing clinical trials will help inform best practices for revascularization strategies and techniques. Vascular care is inconsistent across the USA, with significant variation in access to care revascularization rates and rates of major amputation. Major amputation can be prevented in patients with CLI when optimal medical therapy, lifestyle modification, and revascularization are provided in a multidisciplinary setting.

Abstract
BACKGROUND Endovascular treatment of symptomatic peripheral artery disease has gained widespread acceptance. The efficacy and safety of drug-coated balloon (DCB) angioplasty in the setting of critical limb ischemia in comparison to conventional surgery has not been demonstrated. We have compared our results with DCB angioplasty to conventional bypass surgery in patients with critical limb ischemia (CLI). METHODS A total of 187 patients with CLI treated over a 6-year period between 2006 and 2012 by a single operative team constituted the study population. Between 2006 and 2009, all patients underwent conventional surgery. Between 2009 and 2012, the investigators adopted endovascular approach with the use of IN.PACT Admiral (Medtronic Inc., Santa Rosa, CA, USA). Data collection was achieved prospectively. RESULTS A total 210 procedures (100 surgery, 110 endovascular) were performed over a 6-year period. A 72% of all bypasses were performed using saphenous vein grafts with above-the-knee bypass as the technique of choice in 80% of the cases. 6-mm DCB was used in 41% of the patients. Procedural success rates (98% vs. 99%, NS) as well as clinical success rates (99% vs. 99%, P=NS) and operative mortality (3.7% vs. 2%, NS) was similar in both groups. Primary patency for DCB vs. bypass groups 91.8% vs. 88.9%, respectively (P=0.31) at 12 months and 82.7% vs. 82.8% at 24 months, respectively (P=0.28). Freedom from clinically-driven target lesion revascularization at 12 months was similar in both groups (87.6% vs. 85%, P=0.33). Primary patency for DCB vs. bypass groups at 24 months was 82.7% vs. 82.8%, respectively (P=0.28). CONCLUSIONS DCB angioplasty yields comparable results to surgery in the setting of critical ischemia. The efficacy and the safety of DCBs in more complex lesions is to be investigated with randomized trials.

Abstract
Retrograde pedal access is a technique utilized with increasing frequency by many interventionists to address patients with advanced multilevel peripheral artery disease and significant comorbidities. This approach to revascularization is being used both in patients who fail traditional antegrade access and in some patients thought to be poor candidates for antegrade approach. However, the lack of randomized controlled trial data, or long-term results, coupled with the associated potential risks including dissection, spasm, and thrombosis have rendered retrograde pedal access a controversial topic. This article details the pros and cons associated with the debate surrounding retrograde pedal access and highlights the current literature and remaining questions regarding outcomes of this technique.

Abstract
Outpatient use of atherectomy for peripheral arterial disease has grown rapidly and outcomes are poorly understood. We analyzed outcomes of atherectomy done for claudication, comparing office and hospital outpatient settings. Analysis of Medicare Part B claims data was performed for incident femoral–popliteal or tibial–peroneal atherectomy from 2012 to 2014. Longitudinal analysis assessed services 18 months before, during, and up to 18 months after the incident peripheral vascular intervention (PVI). Differences between office-based and hospital outpatient-based settings were assessed using χ2 and Fisher exact tests. Comparing procedure settings, significant differences in race (femoral–popliteal: P = .04, tibial–peroneal: P = .001), chronic renal failure (femoral–popliteal: P = .002), and hypertension (femoral–popliteal: P = .01, tibial–peroneal: P = .006) were found. Nine hundred twenty-four patients undergoing femoral–popliteal atherectomy were analyzed (262 office based, 662 hospital outpatient based); 42.7% of office-based and 36.9% of hospital outpatient-based femoral–popliteal atherectomy patients had repeat PVI within 18 months ( P = .10). Major amputation was performed in 2.3% and 3.2% of patients in office and hospital outpatient settings, respectively ( P = .47). Four hundred twenty-three patients undergoing tibial–peroneal atherectomy were analyzed (202 office based, 221 hospital outpatient based); 46.5% of office-based and 38.9% of hospital outpatient-based tibial–peroneal atherectomy patients had repeat PVI within 1 year ( P = .11). Major amputation was performed in 5.0% and 8.1% of patients in office and hospital outpatient settings, respectively ( P = .19). Our study demonstrates higher than expected rates of major amputation for patients undergoing peripheral arterial atherectomy with regard to previously reported rates. Further studies may be required to prove the efficacy and safety of atherectomy for occlusive disease in the femoral–popliteal and tibial–peroneal segments to ensure outcomes are not worse than the natural history of medically managed claudicants.

Abstract
In this seminar, I would like to discuss the recent hybrid operations in patients with peripheral arterial diseases. Hybrid is generally defined as combinations of different types of things. In the surgical community, it is loosely defined as therapy combining open surgery (OS) and endovascular therapy (EVT). In practice, combination surgery of diseased inflow vessels by EVT and outflow vessels by OS is a typical example, namely, the combination therapy of thromboendarterectomy (TEA) for common femoral artery and EVT (PTA and stenting) for iliac artery in patients with PAD (ilio-femoral lesions). Also, there is the potential of various combinations of OS and EVT for complex lesions. Unfortunately, we do not have specific guidelines for hybrid therapy of PAD, but in clinical practices, justified decision-making for surgical indication is strictly required. I emphasize that the cardiovascular surgeon (or vascular specialist) must have the ability of decision-making for suitable combination therapy of OS and EVT which adheres to existing specific guidelines.

Abstract
OBJECTIVE There are conflicting reports about outcomes after infrainguinal bypass for chronic limb-threatening ischemia (CLTI) in patients with diabetes. We compared perioperative outcomes between patients with and patients without diabetes in the current era. METHODS The National Surgical Quality Improvement Program vascular module, 2011 to 2014, was used to identify patients undergoing infrainguinal revascularization for CLTI. Patients with and without diabetes were compared in terms of presentation, comorbidities, operative approach, and 30-day outcomes. Major adverse limb events (MALEs) included 30-day major reintervention or amputation, and major adverse cardiovascular events (MACEs) included 30-day myocardial infarction, cardiac arrest, stroke, or death. Multivariable logistic regression was used to adjust for baseline differences. RESULTS We identified 8887 patients undergoing open (5744; 50% diabetic) or endovascular (3143; 62% diabetic) treatment for CLTI. Patients with diabetes were younger and more often nonwhite, nonsmokers, and obese. Patients with diabetes presented more often with tissue loss (71% vs 47%; P < .001) and were more likely to be treated with endovascular intervention (41% vs 29%; P < .001). The 30-day mortality was similar before (open, 3.1% vs 2.8% [P = .53]; endovascular, 2.6% vs 2.1% [P = .37]) and after adjustment for baseline differences (open: odds ratio [OR], 1.1 [95% confidence interval (CI), 0.7-1.5]; endovascular: OR, 1.2 [95% CI, 0.7-2.0]). Patients with diabetes had longer lengths of stay (open, 8 vs 6 days [P < .001]; endovascular, 3 vs 2 days [P < .001]) and higher 30-day readmission rates (open, 21% vs 18% [P < .01]; endovascular, 20% vs 15% [P < .01]); however, these differences were no longer significant after adjustment for baseline differences. Patients with diabetes had a higher rate of MACEs (7.0% vs 5.1%; P < .01) and lower rate of MALEs (8.1% vs 10%; P < .01) after bypass. After adjustment, patients with diabetes still had a lower rate of MALEs (OR, 0.7; 95% CI, 0.6-0.9) but no longer had a higher rate of MACEs (OR, 1.2; 95% CI, 0.9-1.6). CONCLUSIONS CLTI patients with diabetes undergoing revascularization have similar 30-day outcomes compared with those without diabetes, although they appear to be at lower risk for MALEs after bypass. Prolonged length of stay and readmission in patients with diabetes is not due to underlying diabetic disease but likely secondary to other baseline comorbidities, such as higher rates of tissue loss. Concern for worse perioperative outcomes in patients with diabetes after lower extremity bypass is unsubstantiated and should not discourage a physician from performing an open bypass.

Abstract
BACKGROUND Femoro-popliteal bypass is implemented to save limbs that might otherwise require amputation, in patients with ischaemic rest pain or tissue loss; and to improve walking distance in patients with severe life-limiting claudication. Contemporary practice involves grafts using autologous vein, polytetrafluoroethylene (PTFE) or Dacron as a bypass conduit. This is the second update of a Cochrane review first published in 1999 and last updated in 2010. OBJECTIVES To assess the effects of bypass graft type in the treatment of stenosis or occlusion of the femoro-popliteal arterial segment, for above- and below-knee femoro-popliteal bypass grafts. SEARCH METHODS For this update, the Cochrane Vascular Information Specialist searched the Vascular Specialised Register (13 March 2017) and CENTRAL (2017, Issue 2). Trial registries were also searched. SELECTION CRITERIA We included randomised trials comparing at least two different types of femoro-popliteal grafts for arterial reconstruction in patients with femoro-popliteal ischaemia. Randomised controlled trials comparing bypass grafting to angioplasty or to other interventions were not included. DATA COLLECTION AND ANALYSIS Both review authors (GKA and CPT) independently screened studies, extracted data, assessed trials for risk of bias and graded the quality of the evidence using GRADE criteria. MAIN RESULTS We included nineteen randomised controlled trials, with a total of 3123 patients (2547 above-knee, 576 below-knee bypass surgery). In total, nine graft types were compared (autologous vein, polytetrafluoroethylene (PTFE) with and without vein cuff, human umbilical vein (HUV), polyurethane (PUR), Dacron and heparin bonded Dacron (HBD); FUSION BIOLINE and Dacron with external support). Studies differed in which graft types they compared and follow-up ranged from six months to 10 years.Above-knee bypassFor above-knee bypass, there was moderate-quality evidence that autologous vein grafts improve primary patency compared to prosthetic grafts by 60 months (Peto odds ratio (OR) 0.47, 95% confidence interval (CI) 0.28 to 0.80; 3 studies, 269 limbs; P = 0.005). We found low-quality evidence to suggest that this benefit translated to improved secondary patency by 60 months (Peto OR 0.41, 95% CI 0.22 to 0.74; 2 studies, 176 limbs; P = 0.003).We found no clear difference between Dacron and PTFE graft types for primary patency by 60 months (Peto OR 1.67, 95% CI 0.96 to 2.90; 2 studies, 247 limbs; low-quality evidence). We found low-quality evidence that Dacron grafts improved secondary patency over PTFE by 24 months (Peto OR 1.54, 95% CI 1.04 to 2.28; 2 studies, 528 limbs; P = 0.03), an effect which continued to 60 months in the single trial reporting this timepoint (Peto OR 2.43, 95% CI 1.31 to 4.53; 167 limbs; P = 0.005).Externally supported prosthetic grafts had inferior primary patency at 24 months when compared to unsupported prosthetic grafts (Peto OR 2.08, 95% CI 1.29 to 3.35; 2 studies, 270 limbs; P = 0.003). Secondary patency was similarly affected in the single trial reporting this outcome (Peto OR 2.25, 95% CI 1.24 to 4.07; 236 limbs; P = 0.008). No data were available for 60 months follow-up.HUV showed benefits in primary patency over PTFE at 24 months (Peto OR 4.80, 95% CI 1.76 to 13.06; 82 limbs; P = 0.002). This benefit was still seen at 60 months (Peto OR 3.75, 95% CI 1.46 to 9.62; 69 limbs; P = 0.006), but this was only compared in one trial. Results were similar for secondary patency at 24 months (Peto OR 4.01, 95% CI 1.44 to 11.17; 93 limbs) and at 60 months (Peto OR 3.87, 95% CI 1.65 to 9.05; 93 limbs).We found HBD to be superior to PTFE for primary patency at 60 months for above-knee bypass, but these results were based on a single trial (Peto OR 0.38, 95% CI 0.20 to 0.72; 146 limbs; very low-quality evidence). There was no difference in primary patency between HBD and HUV for above-knee bypass in the one small study which reported this outcome.We found only one small trial studying PUR and it showed very poor primary and secondary patency rates which were inferior to Dacron at all time points.Below-knee bypassFor bypass below the knee, we found no graft type to be superior to any other in terms of primary patency, though one trial showed improved secondary patency of HUV over PTFE at all time points to 24 months (Peto OR 3.40, 95% CI 1.45 to 7.97; 88 limbs; P = 0.005).One study compared PTFE alone to PTFE with vein cuff; very low-quality evidence indicates no effect to either primary or secondary patency at 24 months (Peto OR 1.08, 95% CI 0.58 to 2.01; 182 limbs; 2 studies; P = 0.80 and Peto OR 1.22, 95% CI 0.67 to 2.23; 181 limbs; 2 studies; P = 0.51 respectively)Limited data were available for limb survival, and those studies reporting on this outcome showed no clear difference between graft types for this outcome. Antiplatelet and anticoagulant protocols varied extensively between trials, and in some cases within trials.The overall quality of the evidence ranged from very low to moderate. Issues which affected the quality of the evidence included differences in the design of the trials, and differences in the types of grafts they compared. These differences meant we were often only able to combine and analyse small numbers of participants and this resulted in uncertainty over the true effects of the graft type used. AUTHORS' CONCLUSIONS There was moderate-quality evidence of improved long-term (60 months) primary patency for autologous vein grafts when compared to prosthetic materials for above-knee bypasses. In the long term (two to five years) there was low-quality evidence that Dacron confers a small secondary patency benefit over PTFE for above-knee bypass. Only very low-quality data exist on below-knee bypasses, so we are uncertain which graft type is best. Further randomised data are needed to ascertain whether this information translates into an improvement in limb survival.

Abstract
Intra-arterial digital subtraction angiography (DSA) is commonly used for the diagnosis and treatment of patients with critical limb ischemia (CLI). The aim of this study was to analyze the incidence of contrast-induced nephropathy (CIN) in patients with CLI and to assess their outcomes. Between May 2013 and May 2014, a prospective and observational study was conducted with 107 patients admitted exclusively for CLI treatment. The main outcomes included hemodialysis independence (HI) and overall survival (OS), as assessed by Kaplan-Meier curves. Overall, there was a predominance of males (57%), with a mean age of 70.5 (10.7) years. The incidence of CIN was 35.5%, and chronic kidney failure was the only factor associated with elevated risk of this condition (relative risk [RR] = 1.9; 95% confidence interval = 1.17-3.09; P = .017). The median follow-up was 645 days, and in 720-day analyses, patients who experienced CIN had worse HI (81.2% vs 96.3%; P = .0107) and OS (49.5% vs 66.3%; P = .0463). The current study found a high incidence of CIN in patients with CLI after DSA. This renal impairment was associated with a worse prognosis in terms of survival.

Abstract
Data on efficacy outcomes of endovascular versus surgical revascularization in patients with critical limb ischemia (CLI) in contemporary practice are limited. In this prospective cohort study, 353 consecutive patients with CLI were enrolled and allocated to endovascular (PTA [percutaneous transluminal angioplasty]), surgical (SURG), or no revascularization (No REVASC) after interdisciplinary consensus. Outcome measures were sustained primary clinical success (sPCS; survival without major amputation, repeated target extremity revascularization, and freedom from CLI), limb salvage, and amputation-free survival. Propensity-matched Kaplan-Meier analyses and stratified log-rank tests were performed. The PTA, SURG, and No REVASC groups consisted of 264, 62, and 27 patients, respectively. Compared to SURG patients, PTA patients were significantly older, had more risk factors, and more often had ischemic lesions. Propensity score-adjusted analyses showed no significant differences: sPCS was 51.3%/52.2%, limb salvage rate 91.5%/93.7%, and major amputation-free survival 90.5%/87.2% at 12 months for PTA and SURG, respectively. Amputation-free survival for the No REVASC group was 69% at 12 months. In conclusion, endovascular and surgical revascularization in CLI has comparable efficacy outcomes after 12 months. Contemporary overall outcome of patients with CLI is considerably better compared to earlier studies.

Abstract
Critical limb ischemia (CLI) is the most severe form of peripheral arterial disease (PAD) that may result in limb loss and even death; thus, the fast and proper treatment should be employed as earlier as possible to prevent these catastrophic consequences. Arterial revascularization is almost always an indispensable treatment option for CLI. Although both endovascular and surgical revascularization procedures have an important role, nowadays, the hybrid revascularization as a combination of these revascularization procedures has also gained increasing popularity in the treatment of patients with CLI. This review provides an update on the arterial revascularization strategies for the treatment of CLI.

Abstract
Patients with critical limb ischemia necessitate immediate intervention to restore blood flow to the affected limb. Endovascular procedures are currently preferred for these patients. We describe the case of an 80-year-old female patient who presented to our department with ischemic rest pain and ulceration of the left limb. The patient had history of left femoral popliteal bypass surgery, femoral thromboendarterectomy and patch angioplasty of the same limb 2 years ago. Doppler sonography and magnetic resonance angiography revealed an occlusion of the left superficial femoral artery (SFA) and popliteal artery and of all three infra-popliteal arteries. Due to severe comorbidities, the patient was scheduled for a digital subtraction angiography. An antegrade approach was first attempted, however the occlusion could not be passed. After revision of the angiography acquisition, a stent was identified at the level of the mid SFA, which was subsequently directly punctured, facilitating the retrograde crossing of the occlusion. Thereafter, balloon angioplasty was performed in the SFA, popliteal artery and posterior tibial artery. The result was considered suboptimal, but due to the large amount of contrast agent used, a second angiography was planned in 4 wk. In the second session, drug coated balloons were used to optimize treatment of the SFA, combined with recanalization of the left fibular artery, to optimize outflow. The post-procedural course was uneventful. Ischemic pain resolved completely after the procedure and at 8 wk of follow-up and the foot ulceration completely healed.

Abstract
True axillary artery aneurysms in children are rare and mostly caused by blunt trauma. Idiopathic bilateral axillary aneurysms in children are even more infrequent, and evidence for optimal management is scarce. Moreover, the maximum follow-up time of interventions reported in pediatric axillary artery aneurysms was less than 1 year, and long-term outcomes remained unknown. In this report, we presented a 6-year-old child with bilateral axillary artery aneurysms treated by saphenous vein reconstruction with a 5-year follow-up. Meanwhile, we reviewed the etiology and treatment of true axillary artery aneurysm in children, which we hope would add information to the scarce evidence of management of true axillary artery aneurysms in children.

Abstract
Background Owing to the aging population, the number of elderly patients with critical limb ischemia (CLI) has increased. The consequence of amputation is immense. However, at the moment, information about the mortality after amputation in the elderly vascular patients is unknown. For this reason, this study evaluated mortality rates and patient-related factors associated with mortality after a major amputation in elderly patients with CLI. Methods From 2006 to 2013, we included patients aged >70 years who were treated for chronic CLI by primary or secondary major amputation within or after 3 months of initial therapy (revascularization or conservative management). Outcome measurements were mortality after major amputation and factors associated with mortality (age, comorbidity and timing of amputation). Results In total, 168/651 patients (178 legs; 26%) underwent a major amputation. Patients were stratified by age: 70–80 years (n=86) and >80 years (n=82). Overall mortality after major amputation was 44%, 66% and 85% after 1, 3 and 5 years, respectively. The 6-month and 1-year mortality in patients aged 80 years or older was, respectively, 59% or 63% after a secondary amputation <3 months versus 34% and 44% after a secondary amputation >3 months. Per year of age, the mortality rate increased by 4% (P=0.005). No significant difference in mortality after major amputation was found in the presence of comorbidity or according to Rutherford classification. Conclusion Despite developments in the treatment of CLI by revascularization, amputation rates remain high and are associated with tremendous mortality rates. Secondary amputation after a failed attempt of revascularization causes a higher mortality. Further research concerning timing of amputation and patient-related outcome is needed to evaluate if selected patients might benefit from primary amputation.

Abstract
Critical limb ischemia (CLI) is the most advanced form of peripheral artery disease. It is associated with significant morbidity and mortality and high management costs. It carries a high risk of amputation and local infection. Moreover, cardiovascular complications remain a major concern. Although it is a well-known entity and new technological and therapeutic advances have been made, this condition remains poorly addressed, with significantly heterogeneous management, especially in nonexperienced centers. This review, from a third-level dedicated inpatient and outpatient cardioangiology structure, aims to provide an updated summary on the topic of CLI of its complexity, encompassing epidemiological, social, economical and, in particular, diagnostic/imaging issues, together with potential therapeutic strategies (medical, endovascular, and surgical), including the evaluation of cardiovascular risk factors, the diagnosis, and treatment together with prognostic stratification.

Abstract
AIM The incremental cost of peripheral orbital atherectomy system (OAS) plus balloon angioplasty (BA) versus BA-only for critical limb ischemia was estimated. MATERIALS & METHODS A deterministic simulation model used clinical and healthcare utilization data from the CALCIUM 360° trial and current cost data. Incremental cost of OAS + BA versus BA-only included differential utilization during the procedure and adverse-event costs at 3, 6 and 12-months. RESULTS For every 100 procedures, incremental annual costs to the hospital were US$350,930 lower with OAS + BA compared with BA-only. Despite higher upfront costs, savings were realized due to reduced need for revascularization, amputation and end-of-life care over 6-12-month postoperative period. CONCLUSION Atherectomy with OAS prior to BA was associated with cost savings to the hospital.

Abstract
Black patients have a higher prevalence of peripheral artery disease (PAD) than white patients, and also tend to have a greater extent and severity of disease, and poorer outcomes. The association of race with quality of health (QOH) after peripheral vascular intervention (PVI), however, is less well-known. In our study, we hypothesized that after PVI, black patients experience worse QOH than white patients. We retrospectively assessed racial differences in health status using responses to the Peripheral Arterial Questionnaire (PAQ) at baseline (pre-PVI) and up to 6 months following PVI among 387 patients. We used the PAQ summary score (which includes physical limitation, symptoms, social function and quality of life) as a measure of QOH. We compared QOH scores at baseline and at follow-up after PVI between black ( n=132, 34.1%) and white ( n=255, 65.9%) patients. We then computed the change in score from baseline to follow-up for each patient (the delta) and compared the median delta between the two groups. Multivariable regression was used to model the delta QOH after controlling for factors associated with race or with the delta QOH. There was no significant difference in mean QOH by race either at baseline ( p=0.09) or at follow-up ( p=0.45). There was no significant difference in the unadjusted median delta by race (white 25.3 vs black 21.5, p=0.28) and QOH scores improved significantly at follow-up in both groups, albeit the improvement was marginally lower in black compared with white patients after adjustment for baseline confounders ( b = -6.6, p=0.05, 95% CI -13.2, -0.11).

Ann Vasc Surg 2017; 44:253-260. [PMID: 28479423 DOI: 10.1016/j.avsg.2017.01.027] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2016] [Revised: 12/06/2016] [Accepted: 01/15/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND There has been growing scrutiny in the treatment of patients with peripheral artery disease due to the utilization of resources to manage this complex patient population. The purpose of this study was to determine the factors associated with prolonged length of stay (LOS > 7 days) following lower extremity bypass using data from the Vascular Quality Initiative as well as to define the additional costs incurred due to prolonged LOS in our health system. METHODS Summary statistics were performed of patients undergoing lower extremity bypass from 2010 to 2015. Student's t-tests and χ2 tests were performed to compare those with and without prolonged LOS. Multivariable logistic regression was then performed to determine the independent predictors for increased LOS. We then compared our institutional LOS with that of representative institutions from the University Health System Consortium and evaluated the impact of prolonged LOS on limb salvage and survival. RESULTS This study included 334 patients with a mean age of 66.4 ± 12.4 years, 64.7% males, 58.5% of white race, 11.1% on dialysis, 80.5% smokers, and 53.6% with diabetes. The mean LOS was 15.7 ± 12.2 days. Prolonged LOS was associated with transfer (15.4% vs. 2.3%, P = 0.001), diabetes (58.3% vs. 40.2%, P = 0.004), critical limb ischemia (71.3% vs. 49.4%, P < 0.001), preoperative need for ambulatory assistance (44.5% vs. 16.1%, P < 0.001), prior ipsilateral bypass (6.9% vs. 1.1%, P = 0.042), urgent surgery (39.7% vs. 9.8%, P < 0.001), tibial or distal target vessel (52.7% vs. 28.0%, P < 0.001), use of vein (65.4% vs. 46.3%, P = 0.002), return to operating room (42.6% vs. 1.2%, P < 0.001), ambulatory assistance (65.0% vs. 34.1%, P < 0.001) as well as discharge anticoagulant (22.8% vs. 9.8%, P = 0.010). Multivariable logistic regression identified urgency (odds ratio [OR] = 5.09, 95% confidence interval [CI] 2.16-12.02, P < 0.001), critical limb ischemia (OR = 3.12, 95% CI 1.65-5.90, P < 0.001), return to OR (OR = 40.30, 95% CI 5.36-303.20, P < 0.001), use of vein (OR = 2.19, 95% CI 1.18-4.07, P = 0.013), and the need for anticoagulation at discharge (OR = 2.56, 95% CI 1.03-6.33, P = 0.043) as independent predictors of LOS > 7 days. Prolonged hospital stays accounted for an additional $40,561.64 in total cost and $26,028 in direct costs incurred. Despite these increased costs, limb salvage and overall survival were not adversely impacted in the prolonged LOS group in follow-up. CONCLUSIONS Lower extremity bypass is associated with a longer than expected LOS in our health system, much of which can be attributed to return to the OR for minor amputations and wound issues. This led to added total and direct costs, where the majority of this increase was attributable to prolonged LOS. Limb salvage and overall survival were preserved, however, in this subset of patients in follow-up. These findings suggest that lower extremity bypass patients are a resource-intensive population of patients, but that these costs are worthwhile in the setting of preserved limb salvage and overall survival.

Variability in Atherosclerotic Disease Progression within the Infrainguinal Arterial Circulation is Dependent on Both Patient and Anatomical Factors. Ann Vasc Surg 2017; 44:289-298.

Abstract
BACKGROUND Studies suggest 25% of patients with symptomatic peripheral arterial disease develop symptom progression over time, yet there is minimal data related to actual atherosclerotic progression. METHODS Patients who underwent consecutive duplex imaging of the lower limb arteries, at least 6 months apart with no intervening arterial intervention, were identified. Atherosclerotic burden was determined for both femoropopliteal (FP) and crural (CR) arterial segments utilizing the Bollinger score (BoS). Overall change in BoS over time was determined, and patients were divided into group 1: disease progression and group 2: no change/disease regression. Patient demographics, comorbidities, and long-term outcomes were collated. RESULTS A total of 215 FP segments (155 men; median age 74 years) were assessed with 82 limbs showing atherosclerotic disease progression. FP atherosclerotic progression was associated with increased age, a diagnosis of ischemic heart disease and hypertension, and a lack of prescription of both an antiplatelet therapy and an angiotensin-converting enzyme inhibitor (all P < 0.05). FP atherosclerotic progression was also associated with an increased longer term mortality rate. A total of 272 CR arterial segments (190 men; median age 74 years) were assessed with 86 limbs showing atherosclerotic disease progression. CR atherosclerotic disease progression was associated with a diagnosis of diabetes mellitus at baseline (P = 0.019). CONCLUSIONS A number of variable factors predict atherosclerotic progression. Differences exist between factors and the arterial segments affected (FP/CR). This suggests that underlying atherosclerotic processes may vary depending on arterial segment, warranting further investigation.

Abstract
AIMS The association of coronary arterial calcification with cardiovascular morbidity and mortality is well-recognized. Lower limb arterial calcification (LLAC) is common in PAD but its impact on subsequent health is poorly described. We aimed to determine the association between a LLAC score and subsequent cardiovascular events in patients with symptomatic peripheral arterial disease (PAD). METHODS LLAC scoring, and the established Bollinger score, were derived from a database of unenhanced CT scans, from patients presenting with symptomatic PAD. We determined the association between these scores outcomes. The primary outcome was combined cardiac mortality and morbidity (CM/M) with a secondary outcome of all-cause mortality. RESULTS 220 patients (66% male; median age 69 years) were included with follow-up for a median 46 [IQR 31-64] months. Median total LLAC scores were higher in those patients suffering a primary outcome (6831 vs. 1652; p = 0.012). Diabetes mellitus (p = 0.039), ischaemic heart disease (p = 0.028), chronic kidney disease (p = 0.026) and all-cause mortality (p = 0.012) were more common in patients in the highest quartile of LLAC scores. The area under the curve of the receiver operator curve for the LLAC score was greater (0.929: 95% CI [0.884-0.974]) than for the Bollinger score (0.824: 95% CI [0.758-0.890]) for the primary outcome. A LLAC score ≥ 4400 had the best diagnostic accuracy to determine the outcome measure. CONCLUSION This is the largest study to investigate links between lower limb arterial calcification and cardiovascular events in symptomatic PAD. We describe a straightforward, reproducible, CT-derived measure of calcification-the LLAC score.

Patient selection and perioperative outcomes of bypass and endovascular intervention as first revascularization strategy for infrainguinal arterial disease. J Vasc Surg 2017; 67:206-216.e2.

Abstract
OBJECTIVE The optimal initial revascularization strategy remains uncertain for patients with peripheral arterial disease. The purpose of this study was to evaluate current nationwide selection and perioperative outcomes of patients undergoing bypass or endovascular intervention for infrainguinal disease in those with no prior ipsilateral revascularization. METHODS Patients undergoing nonemergent first-time infrainguinal revascularization were identified in the Targeted Vascular module of the National Surgical Quality Improvement Program (NSQIP) for 2011 to 2014 and stratified by symptom status (chronic limb-threatening ischemia [CLTI] or claudication). Patients treated with endovascular intervention were compared with those who underwent bypass. Multivariable logistic regression was used to evaluate current selection of patients and to establish independent associations between first-time procedures and postoperative outcomes. RESULTS Of 5998 first-time infrainguinal revascularizations performed, 3193 were bypass procedures (63% for CLTI) and 2805 were endovascular interventions (64% for CLTI). Current patient characteristics associated with an endovascular-first approach as opposed to bypass-first in CLTI patients were age ≥80 years, tissue loss, nonsmoking, functional dependence, diabetes, dialysis, and tibial lesions, whereas age ≥80 years, nonwhite race, nonsmoking, diabetes, and tibial lesions were associated with an endovascular approach for claudication. In comparing first-time endovascular intervention with bypass, there was no difference in 30-day mortality in CLTI patients (univariate: 2.1% vs 2.2%; adjusted: odds ratio [OR], 0.7; 95% confidence interval [CI], 0.4-1.1) or claudication patients (0.3% vs 0.6%). Among CLTI patients, endovascular-first intervention was associated with lower rates of major adverse cardiovascular event (3.6% vs 4.7%; OR, 0.6; 95% CI, 0.4-0.9), surgical site infection (0.9% vs 7.7%; OR, 0.1; 95% CI, 0.1-0.2), bleeding (8.5% vs 17%; OR, 0.4; 95% CI, 0.3-0.5), unplanned reoperation (13% vs 17%; OR, 0.7; 95% CI, 0.5-0.8), and unplanned readmission (17% vs 18%; OR, 0.8; 95% CI, 0.7-0.9). Patients with claudication undergoing endovascular-first intervention also had lower rates of major adverse cardiovascular event (0.8% vs 1.6%; OR, 0.4; 95% CI, 0.2-0.95), surgical site infection (0.7% vs 6.6%; OR, 0.1; 95% CI, 0.04-0.2), bleeding (2.3% vs 6.0%; OR, 0.3; 95% CI, 0.2-0.5), unplanned reoperation (4.3% vs 6.6%; OR, 0.6; 95% CI, 0.4-0.9), and unplanned readmission (5.9% vs 9.0%; OR, 0.6; 95% CI, 0.4-0.8). Conversely, endovascular-first intervention was associated with a higher rate of secondary revascularizations within 30 days for CLTI (4.3% vs 3.1%; OR, 1.6; 95% CI, 1.04-2.3) but not for claudication (2.6% vs 1.9%; OR, 1.7; 95% CI, 0.9-3.4). CONCLUSIONS An endovascular-first approach as a revascularization strategy for infrainguinal disease was associated with substantially lower early morbidity but not mortality, at the cost of higher rates of postoperative secondary revascularizations. As a national representation of first-time revascularizations, this study highlights the early endovascular perioperative benefit, although more robust long-term data are needed to adopt either one strategy or the other in select patients with peripheral arterial disease.

Abstract
BACKGROUND Diabetes is one of the major risk factors for peripheral arterial disease. In patients in whom surgery cannot be performed, cell therapy may be an alternative treatment. Since time is crucial for these patients, we propose the use of allogenic mesenchymal cells. METHODS We obtained mesenchymal cells derived from the fat tissue of a healthy Sprague-Dawley rat. Previous diabetic induction with streptozotocin in 40 male Sprague-Dawley rats, ligation plus left iliac and femoral artery sections were performed as a previously described model of ischemia. After 10 days of follow-up, macroscopic and histo-pathological analysis was performed to evaluate angiogenic and inflammatory parameters in the repair of the injured limb. All samples were evaluated by the same blind researcher. Statistical analysis was performed using the SPSS v.11.5 program (P < 0.05). RESULTS Seventy percent of the rats treated with streptozotocin met the criteria for diabetes. Macroscopically, cell-treated rats presented better general and lower ischemic clinical status, and histologically, a better trend towards angiogenesis, greater infiltration of type 2 macrophages and a shortening of the inflammatory process. However, only the inflammatory variables were statistically significant. No immunological reaction was observed with the use of allogeneic cells. DISCUSSION The application of allogeneic ASCs in a hind limb ischemic model in diabetic animals shows no rejection reactions and a reduction in inflammatory parameters in favor of better repair of damaged tissue. These results are consistent with other lines of research in allogeneic cell therapy. This approach might be a safe, effective treatment option that makes it feasible to avoid the time involved in the process of isolation, expansion and production of the use of autologous cells.
