[PMID: 38815902 DOI: 10.1016/j.avsg.2024.03.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 02/27/2024] [Accepted: 03/07/2024] [Indexed: 06/01/2024]
Abstract
BACKGROUND In India, a significant scarcity of published data exists regarding chronic limb-threatening ischemia (CLTI) and its management, especially among the elderly population. CLTI, often accompanied by frailty poses a significant healthcare challenge. While endovascular interventions offer hope, there remains a dearth of outcome data for this age group. This study seeks to address this critical gap by investigating the impact of frailty on outcomes, emphasizing amputation-free survival (AFS), wound healing, and health-related quality of life (HRQoL). METHODS Our study included 131 elderly CLTI patients aged ≥70 years who underwent infrainguinal endovascular interventions between April 2018 and August 2021, with a follow-up period of 2 years. Among the patients, 93.9% had diabetes mellitus and 82.4% had hypertension. Clinical frailty was assessed using the clinical frailty scale (CFS). Patients were categorized into group 1 (CFS 1-5) and group 2 (CFS 6-9). Primary outcomes were AFS, wound healing, HRQoL, and their association with frailty. Secondary outcomes included technical success, procedure-related complications, major adverse limb events, major adverse cardiac events, vessel patency, re-intervention rates, and mortality rates including periprocedural and overall mortality. RESULTS Technical success was achieved in 86.3% of patients, with frailty significantly influencing this outcome. Group 2 exhibited reduced technical success (80.8%) compared to group 1 (93.1%). The major amputation rate was 9.2%, with higher rates in group 2 [univariate hazard ratio: 5.20; P = 0.033]. Similarly, group 2 showed elevated overall mortality [univariate hazard ratio: 5.18; P < 0.001]. AFS at 1 and 2 years were 67.9% and 55%, respectively, with higher rates in group 1. Wound healing was achieved in 76.1% of patients (83/109), with frailty significantly associated with delayed wound healing (P < 0.001). Vessel patency at 1 year was observed in 88.8% of patients. HRQoL significantly improved postintervention, with vascular quality of life questionnaire-6 (VascuQol-6) scores increasing from an average of 9 of 24 at baseline to 20 of 24 at 2 years. Frailty score significantly correlated with VascuQol-6 scores at 1 and 2 years (P < 0.0012). Group 1 exhibited higher VascuQol-6 scores than group 2, indicating improved HRQoL during follow-up. CONCLUSIONS Successful endovascular treatments in high-risk CLTI patients promote improved wound healing and post-treatment quality of life. Frailty should be assessed before endovascular interventions as it correlates with adverse outcomes, including amputations and mortality. While revascularization holds promise, caution is advised for frailer patients, emphasizing the importance of personalized care and tailored treatments for elderly CLTI patients.

Abstract
BACKGROUND Critical limb ischemia (CLI) patients take too many medications because they are elderly and frail patients with multiple comorbidities. Polypharmacy is associated with frailty, although its prognostic significance in CLI patients is unknown. In this study, we aimed to determine the prevalence of hyperpolypharmacy among adults with CLI and its effect on 1-year amputation and mortality. METHODS A total of 200 patients with CLI who underwent endovascular therapy (EVT) for below-knee (CTC) lesions were included in this study. Hyperpolypharmacy was defined as using ≥10 drugs. Patients were divided into two groups according to the presence of hyperpolypharmacy. RESULTS We detected hyperpolypharmacy in 66 patients. The incidence of 1-year amputation [24 (36.4) versus 12 (9), p<.001] and mortality [28 (42.4) versus 12 (9), p<.001] were higher in patients with hyperpolypharmacy. Univariate and multivariate cox regression analyses were used to determine the independent predictors of amputation and mortality. In the receiver operating characteristic curve analysis, the cut-off value was defined as 10 or more drug use was able to detect the presence of 1-year mortality with 67.5% sensitivity and 79.4% specificity. The Kaplan-Meier method showed a significant difference (rank p <.001 between log groups), and hyperpolypharmacy was associated with 1-year amputation and mortality. CONCLUSION Hyperpolypharmacy was significantly associated with 1-year mortality and major amputation in CLI patients. Hyperpolypharmacy can be a valuable aid in patient risk assessment in the CLI.

Abstract
OBJECTIVE To assess the comparative effectiveness and temporal changes in quality of life (QoL) outcomes after revascularisation, major lower extremity amputation (MLEA), and conservative management (CM) in chronic limb threatening ischaemia (CLTI). DATA SOURCES MEDLINE, Embase, PsycINFO, CINAHL, and Web of Science. REVIEW METHODS A systematic review and meta-analysis were performed on QoL measured by any QoL instrument in adult patients with CLTI after open surgery (OS), endovascular intervention (EVI), MLEA, or CM. Randomised controlled trials and prospective observational studies published in any language between 1 January 1990 and 21 May 2021 were included. There was a pre-specified measurement time point of six months. Random effects meta-analysis was conducted on total scores for each QoL instrument. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations approach (PROSPERO registration: CRD42021253953). RESULTS Fifty-five studies with 8 909 patients were included. There was significant heterogeneity in the methods used to measure QoL, and the study characteristics. In particular, 14 different QoL instruments were used with various combinations of disease specific and generic instruments within each study. A narrative summary is therefore presented. Comparative effectiveness data showed there was reasonable certainty that QoL was similar between OS and EVI at six months. Temporal outcomes suggested small to moderate improvements in QOL six months after OS and EVI compared with baseline. Limited data indicated that QoL can be maintained or slightly improved after MLEA or CM. Treatment effects were overestimated owing to small study effects, selective non-reporting, attrition, and survivorship bias. CONCLUSION QoL after OS and EVI appears to be similar. Revascularisation may provide modest QoL benefits, while MLEA or CM can maintain QoL. However, certainty of evidence is generally low or very low, and interpretation is hampered by significant heterogeneity. There is a need for a CLTI specific QoL instrument and methodological standardisation in QoL studies.

Abstract
OBJECTIVE Critical limb ischemia (CLI) is a progressive form of peripheral artery disease (PAD). Patients with CLI have poor long-term prognosis. The aim of this study was to investigate the value of sarcopenia in terms of 1-year mortality in patients with below-the-knee lesions who underwent endovascular treatment for CLI. METHODS A total of 190 patients with critical limb ischemia who underwent endovascular treatment (EVT) for below-the-knee (BTK) lesions were enrolled in this study. Sarcopenia was defined using the psoas muscle index (PMI). PMI was obtained by calculating the average psoas muscle area (APMA) of the left and right psoas muscles at the third lumbar vertebra level and dividing by the square of the height (cm2/m2). The primary endpoint of the study was 1-year mortality and the secondary endpoint was 1-year amputation. Patients were divided into 2 groups according to presence of sarcopenia. RESULTS We detected sarcopenia in 64 patients. The mean age, height, and EF were higher in sarcopenia group. The psoas muscle area, weight, psoas muscle index, body-mass index, albumin level, and GFR were lower in sarcopenia group. The incidence of amputation (11.9% vs 29.7%, p = 0.003) and mortality (15.1% vs 35.9%, p = 0.001) were higher in patients with sarcopenia. Univariate and multivariate logistic regression analyses were used to determine the independent predictors of amputation and mortality. The survival curve for 1-year using the sarcopenia was analyzed using the Kaplan-Meier method, and statistical analysis was performed with the log-rank test. The presence of sarcopenia, glomerular filtration rate level, and low ejection fraction were found to be independent predictors of mortality. CONCLUSIONS Sarcopenia was associated with 1-year mortality in patients with CLI undergoing EVT for BTK lesions. Also, patients with sacropenia had higher 1-year amputation rates. Sarcopenia may be a simple method to help patient selection, assessment, and intervention strategy for EVT and may improve patient outcomes.

Abstract
BACKGROUND Treatment of chronic limb threatening ischemia (CLTI) poses a significant clinical challenge despite recent medical advancements. Chronic total occlusion (CTO) lesions make endovascular approaches to CLTI particularly challenging. Open proximal exposure with retrograde access and stenting (OPERAS) aims to solve this challenge through retrograde subintimal crossing of a CTO with direct visualization of proximal re-entry into the true lumen. We describe this novel technique and present its efficacy in eight patients. METHODS We conducted a retrospective case series at a single tertiary academic center. Data for patients who received OPERAS intervention included demographics, peri-operative details, and follow-up information. Statistical analysis was performed on length of stay, major post-operative complications, further intervention, clinical progression at 1 year, and amputation-free survival at 1 year. Immediate technical failure (ITF) and limb-based patency (LBP) at 1 year were calculated. RESULTS Nine limbs underwent OPERAS between January 2019 and March 2020. Inflow was achieved with common femoral artery endarterectomy. All limbs underwent balloon angioplasty and stenting of the SFA, and seven underwent the same procedure in the popliteal artery. ITF was 0% for all nine cases. There were no major post-operative complications, and ankle-brachial index significantly improved pre-and post-operatively (P < .001). Eight limbs (88.9%) sustained amputation-free survival at 1 year, and overall LBP was 67% at 1 year. CONCLUSION Our study presents a hybrid revascularization option to address severe, anatomically complex limbs (GLASS III) that lack a single autogenous conduit for open surgical revascularization. OPERAS addresses a main point of technical failure of subintimal techniques by directly visualizing the wire in the true lumen. Our data suggest that OPERAS can be effective to: (1) improve technical success of luminal re-entry following a subintimal approach; (2) address inflow concurrently with severe femoropopliteal disease; and (3) can be utilized when distal tissue loss is involved.

Abstract
Chronic limb-threatening ischemia (CLTI) causes significant morbidity with profound negative effects on health-related quality of life. As the prevalence of peripheral artery disease and diabetes continue to rise in our aging population, the public health impact of CLTI has escalated. Patient-reported outcome measures (PROMs) have become common and important measures for clinical evaluation in both clinical care and research. PROMs are important for the measurement of clinical effectiveness and cost effectiveness and for shared decision-making on treatment options. However, the PROMs used to describe the experience of patients with CLTI are heterogeneous, incomplete, and lack specific applicability to the underlying disease processes and diverse populations. For example, certain PROMs exist for patients with extremity wounds, and other PROMs exist for patients with pain, and still others exist for patients with vascular disease. Despite this multiplicity of tools, no single PROM encompasses all of the components necessary to describe the experiences of patients with CLTI. This significant unmet need is evident from both published reports and contemporary large-scale clinical trials in the field. In this systematic review, we review the current use of PROMs for patients with CLTI in clinical practice and in research trials and highlight the gaps that need to be addressed to develop a unifying PROM instrument for CLTI.

Abstract
BACKGROUND There are limited data on differences in angiographic distribution of peripheral artery disease and endovascular revascularization strategies in patients presenting with intermittent claudication (IC) and critical limb ischemia (CLI). We aimed to compare anatomic features, treatment strategies, and clinical outcomes between patients with IC and CLI undergoing endovascular revascularization. METHODS We examined 3326 patients enrolled in the Excellence in Peripheral Artery Disease registry from 2006 to 2019 who were referred for endovascular intervention for IC (n=1983) or CLI (n=1343). The primary outcome was 1-year major adverse limb events, which included death, repeat target limb revascularization, or target limb amputation. RESULTS Patients with CLI were older and more likely to have diabetes and chronic kidney disease and less likely to receive optimal medical therapy compared with IC. Patients with IC had higher femoropopliteal artery interventions (IC 87% versus CLI 65%; P<0.001), while below the knee interventions were more frequent in CLI (CLI 47% versus IC 12%; P<0.001). Patients with CLI were more likely to have multilevel peripheral artery disease (CLI 32% versus IC 15%, P<0.001). Patients with IC were predominantly revascularized with stents (IC 48% versus CLI 37%; P<0.001) while balloon angioplasty was more frequent in CLI (CLI 37% versus IC 25%; P<0.001). All-cause mortality was higher in patients with CLI (CLI 4% versus IC 2%; P=0.014). Major adverse limb event rates for patients with IC and CLI were 16% and 26%, respectively (P<0.001) and remained higher in CLI after multivariable adjustment of baseline risk factors. CONCLUSIONS Patients with IC and CLI have significant anatomic, lesion, and treatment differences with significantly higher mortality and adverse limb outcomes in CLI.

Abstract
Background: Significant geographical variations exist in amputation rates and utilization of diagnostic and therapeutic vascular procedures before lower extremity amputations in the United States. The purpose of this study was to evaluate the rates of diagnostic and therapeutic vascular procedures in the year prior to amputation in a contemporary population and correlate with pathological findings of the amputation specimens. Methods: A retrospective analysis was conducted of non-traumatic amputations from 2011 to 2017 at a rural community hospital. We reviewed the proportion of patients undergoing diagnostic (ankle brachial index with duplex ultrasound, computerized tomography angiogram and invasive angiogram) and therapeutic (endovascular and surgical revascularization) vascular procedures in the year prior to amputation. Prevalence of tissue viability and osteomyelitis were evaluated in all amputated specimens and atherosclerotic vascular disease (ASVD) was evaluated in major amputations. We also analyzed primary amputation rates among different subgroups. Results: 698 patients were included with 248 (36%) major amputations and 450 (64%) minor amputations. Any diagnostic procedure was performed in 59% of the major amputations and 49% of the minor amputations (P = 0.01). Any therapeutic revascularization procedure was performed in 34% of the major amputations and 28% of the minor amputations (P = 0.08). The pathology of major amputation specimens revealed severe ASVD in 57% and mild-moderate ASVD in 27% of specimens. Tissue viability was significantly higher in major amputations (90% vs 30%, P = 0.04) and osteomyelitis was significantly higher in minor amputations (50% vs 14%, P = 0.03). Primary amputations were performed in 66% of major amputations, 72% of minor amputations, 81% with mild to moderate ASVD and 54% with severe ASVD. Conclusion: Diagnostic and therapeutic vascular procedures appear under-utilized for patients undergoing lower extremity amputations at a rural community hospital. ASVD rates and tissue viability imply that revascularization could be of significant benefit to avoid major amputation.

Abstract
BACKGROUND/PURPOSE Although the incidence of peripheral artery disease (PAD) and amputations is higher in Native Americans (NA) than Caucasians, the study of revascularization NA is limited, resulting in their under representation in clinical studies. Orbital atherectomy (OA) is widely utilized for endovascular revascularization of significantly calcified peripheral arteries and has been shown to improve limb salvage rates. METHODS/MATERIALS A cohort of 74 consecutive PAD subjects undergoing OA treatment was retrospectively analyzed via Kaplan Meier (KM) and Propensity Score Matched (PSM) analysis. RESULTS A significant proportion of the subjects were NA (16.2%). Compared to the non-NA, the NA had higher numerical baseline rates of wounds, dialysis, chronic kidney disease (CKD), and critical limb ischemia, but were numerically less likely to smoke and had similar rates of diabetes. There were very high rates of severe calcification (100% vs. 87%) and pre-procedure diameter stenosis (99% vs. 95%) in both groups. The NA and non-NA had good angiographic outcomes, resulting in low rates of post-procedure residual diameter stenosis (10% vs. 11%). Lastly, KM analysis indicated high freedom from amputation in both groups at 1 year (89% vs. 95%), as well as in the PSM subjects (89% vs. 100%). CONCLUSIONS Despite numerically higher rates of co-morbidities at baseline (e.g., CKD, dialysis, and presence of non-healing wounds), the NA underwent successful revascularization with OA, resulting in high freedom from amputation at 1-year. Given the small sample size of NA, these results may not be generalizable-thus, larger studies on NA are warranted.

Abstract
The complexity of critical limb ischemia (CLI) requires dedicated multidisciplinary teams of different care providers, who will supervise the full cycle of CLI care. Until CLI treatment is fully centralized, such dedicated teams may work as second-opinion tools before major amputation is undertaken in CLI patients. The aim of the study is to assess the effectiveness of a well-timed referral to a dedicated CLI-center of patients scheduled to major amputation elsewhere. A retrospective analysis of all CLI-patients treated in our department between January 2019 and March 2020 was conducted. Only patients scheduled for a major amputation elsewhere and referred to our clinic were included. Primary endpoint was amputation-free survival, whereas technical success, limb salvage, minor amputation rate, re-admission at 30 days, and frequency of medication change from other disciplines were the secondary endpoints. Sixteen patients with 19 treated limbs were identified and included in this analysis. The WIfI (wound, infection and foot ischemia) clinical stage on admission was 2 in 4 limbs (21%), 3 in 5 limbs (26%), and 4 in 10 limbs (53%). All patients underwent advanced endovascular revascularization. Minor amputation was performed in 8 patients (42%). Amputation-free survival at 6 months was 93% with limb salvage rate of 100%. Technical success and re-admission rates at 30 days was 95% and 6%, respectively. There was a medication adjustment from other specialties in 13 (81%) patients. Patients in severe stages of CLI scheduled to major amputation reached high limb salvage and survival rate, since they are referred for a second opinion to a dedicated multidisciplinary CLI team.
