Abstract
PURPOSE To examine the effect of end-stage renal disease (ESRD) on the likelihood of major adverse limb events (MALEs) in patients with Rutherford Category 4-6 critical limb ischemia (CLI) who underwent percutaneous vascular intervention (PVI). MATERIALS AND METHODS Two contemporaneous cohorts of patients who underwent PVI for symptomatic CLI from 2012 to 2022, differing in ESRD status, were matched using propensity score methods. This database identified 628 patients who underwent 1,297 lower extremity revascularization procedures; propensity score matching yielded 147 patients (180 limbs, 90 limbs in each group). Kaplan-Meier and Cox proportional hazard analyses were used to assess the effect of ESRD status on MALEs, stratified into major amputation (further stratified into above-knee amputation and below-knee amputation [BKA]) and reintervention (PVI or bypass). RESULTS After PVI, 31.3% of patients in the matched cohorts experienced a MALE (45.7% ESRD vs 18.2% non-ESRD), and 15.6% experienced a major amputation (27.1% ESRD vs 5.2% non-ESRD). Cox proportional hazards analysis revealed that ESRD was an independent predictor of MALE (hazard ratio [HR], 3.15; 95% CI, 1.58-6.29; P = .001), major amputation (HR, 7.00; 95% CI, 2.06-23.79; P = .002), and BKA (HR, 7.56; 95% CI, 1.71-33.50; P = .008). CONCLUSIONS ESRD is strongly predictive of MALE and major amputation risk, specifically BKA, in patients undergoing PVI for Rutherford Category 4-6 CLI. These patients warrant closer follow-up, and new methods may become necessary to predict and further reduce their amputation risk.

Vadia R, Malyar N, Stargardt T. Cost-utility analysis of early versus delayed endovascular intervention in critical limb-threatening ischemia patients with rest pain. J Vasc Surg 2023; 77:299-308.e2. [PMID: 35843509 DOI: 10.1016/j.jvs.2022.07.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Revised: 05/22/2022] [Accepted: 07/07/2022] [Indexed: 02/03/2023]
Abstract
OBJECTIVE The prevalence of chronic limb-threatening ischemia (CLTI) and poor health outcomes are high in Germany. Serious consequences of CLTI such as amputation and mortality can be effectively prevented by the early use of evidence-based therapeutic measures such as endovascular intervention. We have developed a cost-utility analysis to compare endovascular intervention with bare metal stents (BMSs) and endovascular intervention after conservative treatment from the German payer perspective. METHODS A Markov model, with a 5-year time horizon and seven states, was developed: (1) intervention, (2) stable 1, (3) major amputation, (4) reintervention, (5) stable 2, (6) care, and (7) all-cause death. Transition probabilities were obtained by pooling the outcomes from multiple clinical studies. The costs were estimated using data from the German diagnosis-related group system, the German rehabilitation fund, and related literature. Health-state utilities were obtained from the reported data. The primary outcomes were the quality-adjusted life-years (QALYs) and costs. RESULTS Early BMS intervention after 5 years resulted in a cost of €23,913 and an increase of 2.5 QALYs per patient, and endovascular intervention with BMS after conservative treatment after 5 years resulted in a cost of €18,323 and an increase of 2 QALYs per patient. The incremental cost-effectiveness ratio was €12,438. The number of major amputations was reduced by 6%. The results of the structural, deterministic, and probabilistic sensitivity analyses were robust. CONCLUSIONS Early endovascular intervention with BMS resulted in more QALYs and a reduced risk of major amputation for early-stage CLTI patients. Our results showed that early endovascular intervention is very cost-effective according to World Health Organization recommended cost-effectiveness thresholds. However, the clinical decision regarding the use of early endovascular intervention should be determined by individual patient-level eligibility and the physician's judgment.

The Society for Vascular Surgery Objective Performance Goals for Critical Limb Ischemia are attainable in select patients with ischemic wounds managed with wound care alone. Ann Vasc Surg 2021; 78:28-35. [PMID: 34543715 DOI: 10.1016/j.avsg.2021.06.034] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Revised: 06/28/2021] [Accepted: 06/30/2021] [Indexed: 01/22/2023]
Abstract
BACKGROUND To set therapeutic benchmarks, in 2009 the Society for Vascular Surgery defined objective performance goals (OPG) for treatment of patients with chronic limb threatening ischemia (CLTI) with either open surgical bypass or endovascular intervention. The goal of these OPGs are to set standards of care from a revascularization standpoint and to provide performance benchmarks for 1 year patency rates for new endovascular therapies. While OPGs are useful in this regard, a critical decision point in the treatment of patients with CLTI is determining when revascularization is necessary. There is little guidance in the comprehensive treatment of this patient population, especially in the nonoperative cohort. Guidelines are needed for the CLTI patient population as a whole and not just those revascularized, and our aim was to assess whether CLTI OPGs could be attained with nonoperative management alone. METHODS Our cohort included patients with an incident diagnosis of CLTI (by hemodynamic and symptomatic criteria) at our institution from 2013-2017. The primary outcome measured was mortality. Secondary outcomes were limb loss and failure of amputation-free survival. Descriptive statistics were used to define the 2 groups - patients undergoing primary revascularization and patients undergoing primary wound management. The risk difference in outcomes between the 2 groups was estimated using collaborative-targeted maximum likelihood estimation. RESULTS Our cohort included 349 incident CLTI patients; 60% male, 51% white, mean age 63 +/- 13 years, 20% Rutherford 4, and 80% Rutherford 5. Most patients (277, 79%) underwent primary revascularization, and 72 (21%) were treated with wound care alone. Demographics and presenting characteristics were similar between groups. Although the revascularized patients were more likely to have femoropopliteal disease (72% vs. 36%), both groups had a high rate of infrapopliteal disease (62% vs. 57%). Not surprisingly, the patients in the revascularization group were less likely to have congestive heart failure (34% vs. 42%), complicated diabetes (52% vs. 79%), obesity (19% vs. 33%), and end stage renal disease (14% vs. 28%). In the wound care group, 2-year outcomes were 65% survival, 51% amputation free survival, 19% major limb amputation, and 17% major adverse cardiac event. The wound care cohort had a 13% greater risk of death at 2 years; however, the risk of limb loss at 2 years was 12% less in the wound care cohort. CONCLUSIONS A comprehensive set treatment goals and expected amputation free survival outcomes can guide revascularization, but also assure that appropriate outcomes are achieved for patients treated without revascularization. The 2-year outcomes achieved in this cohort provide an estimate of outcomes for nonrevascularized CLTI patients. Although multi-center or prospective studies are needed, we demonstrate that equal, even improved, limb salvage rates are possible.

Abstract
BACKGROUND The impact of end-stage renal disease (ESRD) on peripheral vascular intervention (PVI) outcome remains incompletely elucidated. OBJECTIVES We sought to compare the outcome of PVI in dialysis patients with those with normal kidney function. METHODS Using weighted data from the National Inpatient Sample database between 2002 and 2014, we identified all peripheral artery disease (PAD) patients aged ≥18 years that underwent PVI. Multivariate logistic regression analysis was performed to examine in-hospital outcomes. RESULTS Of 1,186,192 patients who underwent PVI, 1,066,830 had normal kidney function (89.9%) and 119,362 had ESRD requiring dialysis (10.1%). Critical limb ischemia was more prevalent in dialysis patients (63.2 vs. 34.0%, p < .001). Compared with normal kidney function group, ESRD requiring dialysis was associated with higher in-hospital mortality (1.5 vs. 4.2%, adjusted OR: 2.13 [95% CI: 2.04-2.23]) and longer length of hospital stay (median 3 days, Interquartile range [IQR] (0-6) vs. 7 days, IQR (4-18); p < .001). Dialysis patients had higher incidence of major adverse cardiovascular events (composite of death, myocardial infarction, or stroke; 14.3 vs. 9.8%, p < .001) and net adverse cardiovascular events (composite of MACE, major bleeding, or vascular complications; 40.8 vs. 29.1%, p < .001). ESRD patients less frequently underwent open bypass (5.6 vs. 8.5%, p < .001) and more frequently had major amputation (10.3 vs. 3.0%, p < .001) compared with normal kidney function group. CONCLUSION PAD patients on dialysis who underwent PVI have higher rates of mortality and adverse outcomes as compared to those with normal kidney function.

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
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 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.

Abstract
The prevalence of peripheral artery disease is substantially higher in patients on chronic hemodialysis than in the general population. The presence of calcified lesions characteristic of hemodialysis patients has an adverse influence on the initial success and long-term outcomes of both surgical bypass and endovascular therapy. Although the selection of revascularization strategy depends on whether an autologous vein is available and if the patient has a life expectancy of at least two years, it is difficult to predict the life expectancy in a real-world clinical situation. Endovascular therapy may be appropriate for many hemodialysis patients with poor general condition because of the high risk of perioperative complications and the poor long-term prognosis. Deciding which treatment option is more appropriate should be done on a case-by-case basis, especially in hemodialysis patients with critical limb ischemia.

Abstract
BACKGROUND The 1-year restenosis rate after standard balloon angioplasty (BA) of long lesions in below-the-knee arteries may be as high as 70%. Our aim was to investigate the efficacy and safety of paclitaxel drug-eluting balloon (DEB) for treatment of below the knee lesions in end stage renal disease patients (ESRD) with critical limb ischemia (CLI). METHODS Our study is a retrospective, single-center study. Inclusion criteria were ESRD, critical limb ischemia (Rutherford class 4 or higher) and significant stenosis or occlusion of at least 1 below-the-knee vessel. Target vessel restenosis and reocclusion at 1-year follow-up was the primary end point. Major amputation, was the secondary end point. RESULTS From July 2012 to February 2015, 50 patients identified with ESRD, with CLI, treated with DEB angioplasty. Six patients were lost to follow-up, leaving 44 patients with 55 vessels (mean age, 58.0 ± 6.9 years; 54.5% male). The mean lesion length was 113.4 ± 55.4 mm. BA confined to the infra-popliteal segment alone in 81.8% of cases. Primary patency was 90.4% at 6 months and 62.2% at 12 months. At a mean follow-up of 13.9 ± 3.5 months all cause mortality was 8.1% (N = 3). The ankle brachial index increased from 0.45 ± 0.04 preoperative to 0.88 ± 0.07 postoperative. There was one major amputation (2.7%) and 5 minor amputations at one year (13.5%). CONCLUSION DEB is effective in the treatment of below the knee critical stenosis and occlusions in ESRD patients with critical limb ischemia.

Abstract
Patients with end-stage renal disease (ESRD) who present with critical limb ischemia (CLI) have become an increasingly common and complex treatment problem for vascular surgeons. Dialysis patients have high short-term mortality rates regardless of whether revascularization is pursued. ESRD patients with CLI can be managed with: local wound care, endovascular or surgical revascularization, or amputation. Some patients may heal small foot wounds with local wound care alone, even if distal perfusion is marginal, as long as any infectious process has been controlled. Surgical revascularization has a mortality rate of 5-10% but has a high chance of limb salvage. However, overall 5-year survival may be as low as 28%. Endovascular therapy also carries a high perioperative mortality risk in this population with similar limb salvage rates. Amputation is indicated in patients with advanced stage CLI, as described by the Society for Vascular Surgery’s Wound, Ischemia and foot Infection (WIfI) system. Statistical models predict that endovascular or surgical revascularization strategies are less costly and more functionally beneficial to patients than primary amputation alone. Decisions on how to manage ESRD patients with CLI are complex but revascularization can often result in limb salvage, despite limited overall survival. Dialysis patients with good life expectancy and good quality conduit may benefit most from surgical bypass.

Abstract
OBJECTIVE Analysis of in-hospital outcomes in patients treated for critical limb ischemia (CLI) and end-stage renal disease (ESRD) compared to CLI patients with normal renal function. METHODS A subgroup analysis of the German CRITISCH registry, a prospective multicenter registry, assessing the first-line treatment strategies in CLI patients in 27 vascular centers in Germany was performed. The study cohort was divided into ESRD patients (n = 102) and patients with normal renal function (n = 674; glomerular filtration rate >60/mL/min/1.73 m(2)). The following first-line treatment strategies were assessed: endovascular therapy (EVT), bypass surgery, patch plasty, and no vascular intervention (conservative treatment, primary amputation). Uni- and multivariate analyses were performed to identify differences between groups as to six end points: amputation or death (composite end point), amputation, death, hemodynamic failure, major adverse cardiac and cerebrovascular events, and reintervention. RESULTS Differences between the ESRD and non-ESRD group were found regarding the applied first-line therapy (P = .016): The first-line treatment strategies in ESRD patients were EVT in 64% (n = 65), bypass surgery in 13% (n = 13), patch plasty in 11% (n = 11), and no vascular intervention in 13% (n = 13). In non-ESRD patients, EVT was applied in 48% (n = 326), bypass surgery in 27% (n = 185), patch plasty in 13% (n = 86), and no vascular intervention in 11% (n = 77). For ESRD patients, a noticeably increased risk of the composite end point (odds ratio [OR], 2.62; 95% confidence interval [CI], 1.19-5.79; P = .017), amputation (OR, 3.14; 95% CI, 1.35-7.31; P = .008), and hemodynamic failure (OR, 2.19; 95% CI, 1.19-4.04; P = .012) was observed. CONCLUSIONS CLI patients on dialysis represent a challenging cohort prone to in-hospital death, amputation, and hemodynamic failure. Two-thirds of these high-risk patients are treated with EVT. Present data suggest that this modality is generally considered as the most favorable treatment option in this patient subgroup.

Abstract
Renal insufficiency is associated with an increased incidence of poor outcomes, including cardiovascular events and death, in the general population. Renal dysfunction appears to have a particularly negative impact in patients undergoing vascular surgery and endovascular therapy. Although the exact mechanism is unknown, increased levels of inflammatory and biochemical modulators associated with adverse cardiovascular outcomes, as well as endothelial dysfunction, appear to play a role in the association between renal insufficiency and adverse outcomes. Outcomes after the surgical and endovascular treatment of abdominal aortic aneurysms, carotid disease, and peripheral arterial disease are all negatively affected by renal insufficiency. Patients with renal dysfunction may warrant intervention for the treatment of critical limb ischemia and symptomatic carotid stenosis, given the comparatively worse outcomes associated with medical management. Open repair of aortic aneurysms and carotid intervention for asymptomatic disease in patients with severe renal dysfunction should be performed with significant caution, as the risks of repair may outweigh the benefits in this population. Further study is needed to better delineate the risks of medical management for these conditions in patients with coexisting severe renal dysfunction. Lastly, current guidelines for the management of vascular diseases, including objective performance goals for critical limb ischemia, are likely not applicable in patients with severe renal insufficiency.
