Abstract
INTRODUCTION Critical limb-threatening ischemia (CLTI) is a severe manifestation of peripheral artery disease (PAD) that can lead to limb amputation and significantly reduce quality of life. In addition to guideline-directed medical therapy (GDMT), endovascular therapy and surgical revascularization are the two revascularization options for CLTI. In recent years, there has been an ongoing debate about the best approach for CLTI patients. The purpose of this meta-analysis is to examine the current evidence and compare the clinical outcomes of endovascular therapy and surgical revascularization for CLTI. METHODS We conducted a systematic search of electronic databases (PubMed, Embase, Cochrane Library, and Web of Science) for studies comparing the outcomes of endovascular therapy versus surgery in patients with CLTI. The primary outcomes were major adverse limb events (MALE) and major adverse cardiovascular events (MACE), while secondary outcomes included risk of bleeding, wound complications, readmission, unplanned reoperation, acute renal failure, and length of hospital stay. Pooled data was analyzed using the fixed-effect model or the random-effect model in Review Manager 5.3. The Newcastle-Ottawa Scale and Cochrane risk of bias assessment tool were used to assess the bias of included studies. RESULTS A total of 16 studies (47,609 patients) were included in this meta-analysis. The overall effect favors surgery over endovascular intervention in terms of MALE [odds ratio (OR) 1.13, 95% CI (1.01-1.28), P = 0.04]. Endovascular therapy is associated with lower MACE rates compared to surgery [OR 0.62, 95% CI (0.51-0.76), P < 0.00001]. Furthermore, the risk of bleeding, wound complications, readmission, unplanned reoperation, acute renal failure as well as the length of hospital stay was lower for endovascular intervention. Finally, there was no statistically significant difference in 30-day mortality between the two groups [OR 0.94, 95% CI 0.79-1.12, P = 0.52; Fig. 3i], and the pooled studies were homogeneous [P = 0.39; I2 = 5%]. CONCLUSION Surgery may be the preferred treatment option for CLTI patients, as it is associated with a lower risk of MALE than endovascular therapy. However, endovascular therapy may be associated with a lower risk of MACE and lower rates of bleeding, wound complications, readmission, unplanned reoperation, acute renal failure, and shorter hospital stays. There was no statistically significant difference in 30-day mortality between the two groups. Ultimately, the decision to use endovascular therapy or surgery as the primary treatment strategy should be based on a multi-disciplinary team approach with careful consideration of patient characteristics and anatomy.

Abstract
BACKGROUND Chronic limb-threatening ischemia (CLTI) in patients with end-stage renal disease (ESRD) poses significant challenges in clinical management due to its unique pathology and poor treatment outcomes. This review calls for a tailored classification and risk assessment for these patients to guide better revascularization choices with early minor amputation as a first-line strategy in advanced stages. METHODS This review consolidates key findings from recent literature on CLTI in ESRD, focusing on disease mechanisms, treatment options, and patient outcomes. It evaluates the literature to clarify the decision-making process for managing CLTI in ESRD. RESULTS CLTI in ESRD patients often results in worse clinical outcomes, such as nonhealing wounds, increased limb loss, and higher mortality rates. While the literature reveals ongoing debates regarding the optimal revascularization method, recent retrospective studies and meta-analyses suggest potential benefits of endovascular treatment (EVT) over open bypass surgery (OB) in reducing mortality and wound complications, with comparable amputation-free survival rates. CONCLUSIONS The selection of revascularization methods in ESRD patients with CLTI is complex, necessitating individualized strategies. The importance of early detection and timely intervention is critical to decelerate disease progression and improve revascularization outcomes. There is a shift in these treatment strategies toward less invasive endovascular procedures, acknowledging the limitations these patients face with open revascularization surgeries. Considering early minor amputations after revascularization could prevent worse consequences, reflecting a shift in the approach to managing CLTI in ESRD patients.

Using machine learning to predict outcomes following suprainguinal bypass. J Vasc Surg 2024; 79:593-608.e8. [PMID: 37804954 DOI: 10.1016/j.jvs.2023.09.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Revised: 09/20/2023] [Accepted: 09/24/2023] [Indexed: 10/09/2023]
Abstract
OBJECTIVE Suprainguinal bypass for peripheral artery disease (PAD) carries important surgical risks; however, outcome prediction tools remain limited. We developed machine learning (ML) algorithms that predict outcomes following suprainguinal bypass. METHODS The Vascular Quality Initiative database was used to identify patients who underwent suprainguinal bypass for PAD between 2003 and 2023. We identified 100 potential predictor variables from the index hospitalization (68 preoperative [demographic/clinical], 13 intraoperative [procedural], and 19 postoperative [in-hospital course/complications]). The primary outcomes were major adverse limb events (MALE; composite of untreated loss of patency, thrombectomy/thrombolysis, surgical revision, or major amputation) or death at 1 year following suprainguinal bypass. Our data were split into training (70%) and test (30%) sets. Using 10-fold cross-validation, we trained six ML models using preoperative features (Extreme Gradient Boosting [XGBoost], random forest, Naïve Bayes classifier, support vector machine, artificial neural network, and logistic regression). The primary model evaluation metric was area under the receiver operating characteristic curve (AUROC). The best performing algorithm was further trained using intra- and postoperative data. Model robustness was evaluated using calibration plots and Brier scores. Performance was assessed on subgroups based on age, sex, race, ethnicity, rurality, median Area Deprivation Index, symptom status, procedure type, prior intervention for PAD, concurrent interventions, and urgency. RESULTS Overall, 16,832 patients underwent suprainguinal bypass, and 3136 (18.6%) developed 1-year MALE or death. Patients with 1-year MALE or death were older (mean age, 64.9 vs 63.5 years; P < .001) with more comorbidities, had poorer functional status (65.7% vs 80.9% independent at baseline; P < .001), and were more likely to have chronic limb-threatening ischemia (67.4% vs 47.6%; P < .001) than those without an outcome. Despite being at higher cardiovascular risk, they were less likely to receive acetylsalicylic acid or statins preoperatively and at discharge. Our best performing prediction model at the preoperative stage was XGBoost, achieving an AUROC of 0.92 (95% confidence interval [CI], 0.91-0.93). In comparison, logistic regression had an AUROC of 0.67 (95% CI, 0.65-0.69). Our XGBoost model maintained excellent performance at the intra- and postoperative stages, with AUROCs of 0.93 (95% CI, 0.92-0.94) and 0.98 (95% CI, 0.97-0.99), respectively. Calibration plots showed good agreement between predicted and observed event probabilities with Brier scores of 0.12 (preoperative), 0.11 (intraoperative), and 0.10 (postoperative). Of the top 10 predictors, nine were preoperative features including chronic limb-threatening ischemia, previous procedures, comorbidities, and functional status. Model performance remained robust on all subgroup analyses. CONCLUSIONS We developed ML models that accurately predict outcomes following suprainguinal bypass, performing better than logistic regression. Our algorithms have potential for important utility in guiding perioperative risk mitigation strategies to prevent adverse outcomes following suprainguinal bypass.

J Surg Res 2024; 293:357-363. [PMID: 37806222 DOI: 10.1016/j.jss.2023.09.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2023] [Revised: 08/15/2023] [Accepted: 09/11/2023] [Indexed: 10/10/2023]
Abstract
INTRODUCTION Bypass graft failure and major amputation are among the worst complications after femoropopliteal bypass surgery. In this large multicenter analysis, we examined our incidence and risk factors for failure-to-salvage (FTS) following either bypass surgery or bypass graft failure. METHODS A regional multicenter database was retrospectively queried for all femoropopliteal bypass procedures performed between 2002 and 2021. Re-do bypasses were excluded. The primary outcome was FTS, defined as major ipsilateral limb amputation within 90 d following index bypass surgery or bypass graft failure. Bypass graft failure was defined as critical stenosis or occlusion of the bypass graft requiring reintervention. Graft rescue was defined as bypass graft failure without subsequent major ipsilateral limb amputation within 90 d. Multivariable logistic regression analysis was utilized to identify factors associated with bypass graft failure and FTS. RESULTS Over the study period, 1315 femoropopliteal bypass procedures were performed across five hospitals. There were 25 major amputations within 90 d of initial bypass. Bypass graft failure was diagnosed in an additional 503 (38.3%) patients. Mean time to graft failure was 619 d. On multivariable analysis, bypass for tissue loss (adjusted odds ratio [aOR] 1.38 [95% confidence interval (CI) 1.03-1.83], P = 0.03) was associated with graft failure. Of patients with graft failure, 33 had major amputation, leading to an overall FTS incidence of 4.4% (n = 58) over a mean follow-up period of 3.4 y. Patient demographics, medical comorbidities, and bypass conduits were similar between the FTS and graft rescue groups (n = NS each). The FTS group more frequently underwent bypass for tissue loss (51.7% versus 29.8%, P = 0.002), and an infrageniculate bypass target was more frequently utilized in FTS compared to graft rescue patients (81.0% versus 60.4%, P = 0.002). Anticoagulation (34.5% in FTS versus 37.7% in rescue) and dual antiplatelet therapy (15.5% versus 22.1%, respectively) were similar between groups (P = NS each). On multivariable analysis, factors associated with FTS included infrageniculate target (aOR 2.42 [95% CI 1.22-4.08], P = 0.01), black race (aOR 2.47 [95% CI 1.04-5.84], P = 0.04), and bypass for tissue loss (aOR 4.75 [95% CI 1.41-16.0], P = 0.01). Anticoagulation and dual antiplatelet therapy were not associated with loss of graft patency or FTS. CONCLUSIONS Failure-to-salvage after femoropopliteal bypass surgery is associated with nonmodifiable factors, and may represent progression of underlying disease. These data may help inform vascular surgeons in counseling patients with failing bypass grafts. Further investigation of care delivery factors improving likelihood of graft salvage may be warranted.

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

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

Abstract
With the growing prevalence and mortality of peripheral arterial disease, preoperative assessment, risk stratification, and determining the correct indication for endovascular and open surgical procedures are essential for therapeutic decision-making. The effectiveness of interventional procedures is significantly influenced by the plaque composition and calcification pattern. Therefore, the identification of patients for whom endovascular treatment is the most appropriate therapeutic solution often remains a challenge. The most commonly used imaging techniques have their own limitations and do not provide findings detailed enough for specific, personalized treatment planning. Using state-of-the-art noninvasive and invasive imaging modalities, it is now possible to obtain a view, not only of the complex vascular anatomy and plaque burden of the lower extremity arterial system, but also of complex plaque structures and various pathologic calcium distribution patterns. In the future, as these latest advancements in diagnostic methods become more widespread, we will be able to obtain more accurate views of the plaque structure and anatomic complexity to guide optimal treatment planning and device selection. We reviewed the implications of the most recent invasive and noninvasive lower extremity imaging techniques and future directions.

Abstract
OBJECTIVE To compare the results of endovascular therapy for chronic limb-threatening ischemia (CLTI) in patients categorized under the gray and yellow zones of the patient risk, limb severity, and anatomic pattern (PLAN) concept over a 2-year follow-up period. METHODS Patients who underwent endovascular therapy for peripheral artery disease and presented with CLTI from February 2017 to February 2019 were retrospectively reviewed. The patients were grouped into yellow and gray zones based on the PLAN concept. Preoperative and postoperative walking distances, Rutherford classes, and postoperative target vessel patency rates were recorded and compared between the groups. Follow-up evaluations were performed at 1, 6, 12, and 24 months post-procedure. RESULTS Of the 387 patients evaluated, the yellow and gray groups comprised 88 patients each. The overall patency rates were similar between the groups (84 (95.45%) vs. 81 (92.05%), respectively). The occlusion-/stenosis-free survival times, amputation-free survival time, and mean survival time were not significantly different. However, the gray group had a significantly higher number of atherectomy interventions (74 vs. 59) and crosser devices used (62 vs. 42). CONCLUSION Endovascular therapy is an effective treatment option for patients in the gray zone of the PLAN color coding system.

Abstract
Chronic limb-threatening ischemia is challenging to treat because of the complex patient population, heterogeneity of limb presentations, and complicated arterial pathology. To meet this challenge, vascular surgeons need a broad range of skills to appropriately tailor interventions to each patient's specific needs. One tool in the armamentarium for patients with extensive arterial occlusive disease below the knee is an inframalleolar bypass. However, these procedures require a systematic approach to surgical planning and a high degree of technical competence. We describe our approach to inframalleolar bypass for limb preservation in suitable patients with advanced tibial artery disease.

Abstract
INTRODUCTION Treatment of long femoropopliteal lesions remains a challenge for vascular physicians as patients often present with multilevel complex pathologies and consequently face a high amputation risk and associated mortality. This review aimed to assess the current state of optimal revascularizations for the treatment of long femoropopliteal lesions. EVIDENCE ACQUISITION An online literature research of medical databases for original articles and review articles on open and endovascular revascularization of femoropopliteal lesions was conducted using mesh terms. EVIDENCE SYNTHESIS There has been an accumulation of evidence over the last years that endovascular treatment is a feasible and enduring alternative to open surgery for treatment of long femoropopliteal lesions if the lesions are restricted to the superficial femoral artery. But when disease extends to the infragenual level venous bypass remains superior with regards to long-term patency, clinical improvement and limb-salvage. CONCLUSIONS While the role of venous bypass as a first-line treatment might be declining, especially in frail patients or claudicants, the superior clinical improvement and amputation-free survival highlighted in several trials, demonstrate the relevance of bypass surgery. More randomized clinical trials are needed to verify the non-inferiority of endovascular treatment options to open surgery, especially when arterial disease extends below the knee.

Abstract
Background: Pro-oxidative stress and pro-inflammatory responses can influence each other in the development of atherosclerosis. This study evaluated the relationship between oxidative stress, inflammation, and multiple peripheral artery occlusions in elderly patients (age mean 71.2 ± 8.1 years). Methods: A total of 723 participants were enrolled: 67 healthy subjects, 214 patients with common iliac artery occlusions, 224 patients with popliteal artery occlusions, and 218 patients with femoral artery occlusions. We measured oxidative stress biomarkers (malondialdehyde [MDA], F2-isoprostane [F2-isoP], total oxidant status [TOS], and ischemia-modified albumin [IMA]) and the expressions of molecules in mimecan (MIME)/nuclear factor kappa B (NF-κB)/P53/Toll-like receptor 4 (TLR4) signaling pathway in older patients with multiple peripheral artery occlusions. Results: The levels of MDA, F2-isoP, TOS, IMA, MIME, NF-κB, P53, and TLR4 were increased in the single-site peripheral artery occlusive group when compared with healthy controls (P < .001) and were further increased in the multiple-site peripheral artery occlusive group compared with the single-site peripheral artery occlusive group (P < .001). Conclusion: Oxidative stress may promote inflammatory signaling pathways and lead to multiple peripheral artery occlusions in elderly patients.

Predictors of amputation-free survival after endovascular intervention for chronic limb-threatening ischemia in the modern era. Ann Vasc Surg 2022; 86:268-276. [PMID: 35595207 DOI: 10.1016/j.avsg.2022.04.052] [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: 03/08/2022] [Revised: 04/12/2022] [Accepted: 04/26/2022] [Indexed: 11/01/2022]
Abstract
OBJECTIVE Chronic limb-threatening (CLTI) is associated with 25% limb loss and 25% mortality at 1-year. Its lethality increases to 45% in patients subjected to a major amputation. Percutaneous peripheral intervention (PPI) constitutes an attractive and less morbid treatment option for patients with CLTI. The purpose of this study was to assess amputation-free survival in a contemporary cohort treated with endovascular recanalization and assess its predictors. METHODS Patients with CLTI undergoing endovascular revascularization at a single regional hospital between 2015-2019 were reviewed. Baseline demographic characteristics, Wound, Ischemia, and foot Infection (WIfI) stage, technical details, and clinical outcomes were tabulated. The primary endpoint was amputation-free survival; a p-value < 0.05 was used for univariate screening and inclusion in a multivariable model. RESULTS 137 limbs in 111 patients were studied. Comorbidities were prevalent and included diabetes (65%), congestive heart failure (21%), and dialysis dependence (18%). The majority of revascularized limbs presented with advanced wounds (66% WIfI stages 3-4; 47% Rutherford category 6). Presenting WIfI stages were similar across races (p=0.26). Peripheral interventions most commonly targeted femoropopliteal disease (69%) although 26% were multilevel. Percutaneous atherectomy, stenting and paclitaxel-coated or eluting devices were utilized in 68%, 28%, and 15% of cases, respectively. After a median follow-up of 16 months (IQR=4-29 months), significant independent predictors of reduced AFS included non-white race (HR=2.96 [1.42-6.17]; p=0.004) and WIfI stage 4 wounds (HR=2.23 [1.10-4.52]; p=0.026). At one year following successful revascularization, only 59%±1% of patients were alive with their limb intact. CONCLUSIONS Despite considerable and consistent advances in urban health care delivery and the techniques of PPI, CLTI remains a morbid and deadly disease. Even in the endovascular era, nearly half of all patients presenting with CLTI will lose their limb and/or life within the first year. Unfortunately, late-stage presentation continues to be commonplace. Although endovascular intervention can reliably restore patency to affected arteries, this appears insufficient to restore most patients to health.

Abstract
Chronic limb-threatening ischemia (CLTI) carries a high risk of amputation and warrants urgent intervention. CLTI involving the infrageniculate vessels, in particular, carries a considerably higher risk of major limb amputation. Open surgical bypass is the historical gold standard for the treatment of tibial arterial disease; however, endovascular therapy provides an attractive alternative in this high-risk patient population. In this article, we review the existing literature regarding distal bypass and infrageniculate endovascular intervention in patients with CLTI.

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

Abstract
Purpose: We present a hybrid technique for the treatment of chronic limb-threatening ischemia (CLTI) due to complex, multilevel infrainguinal disease. It consists of an open distal endarterectomy combined with endovascular proximal treatment (the DEEP technique). Materials and Methods: This was a prospective cohort study. Thirty-three limbs (30 patients) were treated. Main inclusion criteria were absence of significant disease in femoral bifurcation associated with a complex infrainguinal pattern. This approach was specially considered in absence of suitable vein for bypass, obesity, hostile groin, and overall high surgical risk. Results: Mean age was 72.8 ± 10 years (ranging 50–93). Most cases presented with severe limb threatening onset (90.9% Rutherford >4 and 81.8% WIfi >3) due to high-complexity infrainguinal disease pattern (Global Limb Anatomic Staging System [GLASS] stage III) in 31/33 (93.9%), chronic total occlusions (CTOs) in 24/33 (72.7%), and severe calcification (Peripheral Arterial Calcium Scoring System [PACSS] grade 4) in 22/33 (66.6%). Mean lesion length was 228.2 mm ± 83 (ranging 40–340 mm). In all procedures, a covered-stent (25 cm length Viabahn) was implanted in a retrograde fashion as the endovascular component. Effective revascularization was achieved in all cases, showing significant clinical and hemodynamic improvement (median pre- and postprocedure ankle-brachial index [ABI]: 0.3 and 0.9, respectively). Results at 12 months follow-up were as follows: 93.9% limb salvage ratio, 75.7% primary patency, 84.6% assisted primary patency, and 90.9% secondary patency. Major adverse limb events (MALE) and cardiovascular events (MACE) occurred in 8/33 (24.2%) and 2/33 (6%), respectively. Mean length of postoperative stay was 7.5 ± 6.92 days (3–27). Conclusion: This less invasive hybrid technique has promising short-term results for limb salvage and it is worth to be included in vascular armamentarium for CLTI revascularization in selected patients.

Abstract
BACKGROUND Autologous cell therapy (ACT) is a new treatment method for patients with diabetes and no-option chronic limb-threatening ischemia (NO-CLTI). We aimed to assess the impact of ACT on NO-CLTI in comparison with standard treatment (ST) in a randomized controlled trial. METHODS Diabetic patients with NO-CLTI were randomized to receive either ACT (n=21) or ST (n=19). After 12 weeks, those in the ST group, who did not improve were treated with ACT. The effect of ACT on ischemia and wound healing was assessed by changes in transcutaneous oxygen pressure (TcPO2) and the number of healed patients at 12 weeks. Pain was evaluated by Visual Analogue Scale (VAS). Amputation rates and amputation-free survival (AFS) were assessed in both groups. RESULTS During the first 12 weeks, TcPO2 increased in the ACT group from 20.8 ± 9.6 to 41.9 ± 18.3 mm Hg (p=0.005) whereas there was no change in the ST group (from 21.2 ± 11.4 to 23.9 ± 13.5 mm Hg). Difference in TcPO2 in the ACT group compared to ST group was 21.1 mm Hg (p=0.034) after 12 weeks. In the period from week 12 to week 24, when ST group received ACT, the TcPO2 in this group increased from 20.1 ± 13.9 to 41.9 ± 14.8 (p=0.005) while it did not change significantly in the ACT in this period. At 24 weeks, there was no significant difference in mean TcPO2 between the two groups. Wound healing was greater at 12 weeks in the ACT group compared to the ST group (5/16 vs. 0/13, p=0.048). Pain measured using VAS was reduced in the ACT group after 12 weeks compared to the baseline, and the difference in scores was again significant (p<0.001), but not in the ST group. There was no difference in rates of major amputation and AFS between ACT and ST groups at 12 weeks. CONCLUSIONS This study has showed that ACT treatment in patients with no-option CLTI and diabetic foot significantly improved limb ischemia and wound healing after 12 weeks compared to conservative standard therapy. Larger randomized controlled trials are needed to study the benefits of ACT in patients with NO-CLTI and diabetic foot disease. TRIAL REGISTRATION The trial was registered in the National Board of Health (EudraCT 2016-001397-15).

Abstract
Background and aims The increasing prevalence of diabetes mellitus is causing a massive growth of peripheral artery disease incidences, a disabling complication of diabetic atherosclerosis, which leads often to the amputation of the affected limb. Critical limb ischemia is the terminal disease stage, which requires a prompt intervention to relieve pain and save limbs. However, patients undergoing revascularization often suffer from cardiovascular, cerebrovascular and major adverse limb events with poor outcomes. Furthermore, the same procedure performed in apparently similar patients has various outcomes and lack of an outcome predictive support causes a high lower limb arterial revascularization rate with disastrous effects for patients. We collected the main risk factors of major adverse limb events in a more readable and immediate format of the topic, to propose an overview of parameters to manage effectively peripheral artery disease patients and to propose basics of a new predictive tool to prevent from disabling vascular complications of the disease. Methods Most recent and updated literature about the prevalence of major adverse limb events in peripheral artery disease was reviewed to identify possible main predictors. Results In this article, we summarized major risk factors of limb revascularization failure and disabling vascular complications collecting those parameters principally responsible for major adverse limb events, which provides physio-pathological explanation of their role in peripheral artery disease. Conclusion We evaluated and listed a panel of possible predictors of MALE (Major Adverse Limb Event) in order to contribute to the development of a predictive score, based on a summary of the main risk factors reported in scientific articles, which could improve the management of peripheral artery disease by preventing vascular accidents.

Abstract
Nontraumatic lower-extremity amputation is a devastating complication of peripheral artery disease (PAD) with a high mortality and medical expenditure. There are ≈150 000 nontraumatic leg amputations every year in the United States, and most cases occur in patients with diabetes. Among patients with diabetes, after an ≈40% decline between 2000 and 2009, the amputation rate increased by 50% from 2009 to 2015. A number of evidence-based diagnostic and therapeutic approaches for PAD can reduce amputation risk. However, their implementation and adherence are suboptimal. Some racial/ethnic groups have an elevated risk of PAD but less access to high-quality vascular care, leading to increased rates of amputation. To stop, and indeed reverse, the increasing trends of amputation, actionable policies that will reduce the incidence of critical limb ischemia and enhance delivery of optimal care are needed. This statement describes the impact of amputation on patients and society, summarizes medical approaches to identify PAD and prevent its progression, and proposes policy solutions to prevent limb amputation. Among the actions recommended are improving public awareness of PAD and greater use of effective PAD management strategies (eg, smoking cessation, use of statins, and foot monitoring/care in patients with diabetes). To facilitate the implementation of these recommendations, we propose several regulatory/legislative and organizational/institutional policies such as adoption of quality measures for PAD care; affordable prevention, diagnosis, and management; regulation of tobacco products; clinical decision support for PAD care; professional education; and dedicated funding opportunities to support PAD research. If these recommendations and proposed policies are implemented, we should be able to achieve the goal of reducing the rate of nontraumatic lower-extremity amputations by 20% by 2030.

Abstract
INTRODUCTION The optimal management of below the knee pathology remains one of the most challenging areas for revascularization in patients presenting with critical limb threatening ischemia. Patients commonly have multilevel lesions and have a high amputation rate and associated mortality. This review aimed to assess the outcomes of below the knee revascularization strategies. EVIDENCE ACQUISITION An online literature search of medical databases for original articles or review articles was conducted using mesh terms. EVIDENCE SYNTHESIS Bypass surgery remains the gold standard for revascularization with good long-term outcomes with regards to patency, limb salvage, and quality of life but is associated with a higher morbidity than the endovascular approach. Given the increasing frailty of our patients, endovascular treatments have become the preferred strategy with results that are now equal to bypass. Hybrid surgery is an increasingly popular option as it combines the benefits of both endovascular and open surgery and although the evidence base is small the outcomes are encouraging. CONCLUSIONS Hybrid surgery offers promising results and could be considered in the treatment of multi-level lower limb arterial disease especially in high-risk patients or those who are not suitable for either open or endovascular techniques as a sole treatment modality.

Arm Vein versus Small Saphenous Vein for Lower Extremity Bypass in the Absence of Both Great Saphenous Veins. Ann Vasc Surg 2020; 70:341-348. [PMID: 32599110 DOI: 10.1016/j.avsg.2020.06.043] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 06/16/2020] [Accepted: 06/17/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND Bypass surgery remains the gold standard for long and complex arterial occlusions in the lower limb. The vein is regarded superior to prosthetic conduits in peripheral arterial bypass surgery. However, this option is often limited because of previous bypass, stripping, or poor quality of the ipsilateral and/or contralateral great saphenous vein (GSV). Under these circumstances, the arm vein (AV) and small saphenous vein (SSV) are the only alternative autologous vein grafts. METHODS We analyzed all consecutive patients treated at an academic tertiary referral center between January 1998 and July 2018 using either the AV or SSV as the main peripheral bypass graft. Study end points were primary patency, secondary patency, limb salvage, and survival. RESULTS In total, 416 bypass procedures using exclusively AV (n = 327) or SSV (n = 89) were performed. There was a predominance of male gender. The majority of risk factors were evenly distributed between groups. The mean follow-up period was 2.3 years (0.9 to 13.3 years). Five-year primary and secondary patency rates were 39% (95% CI: 31-47%) and 67% (59-75%) for AV and 53% (41-66%) and 76% (67-86%) for SSV, respectively (P = 0.2 and 0.25). The five-year limb salvage and survival rates were 71% (68-81%) and 84% (77-90%) for AV and 78% (67-88%) and 90% (82-98%) for SSV, respectively (P = 0.52 and 0.11). CONCLUSIONS Both AV and SSV are equally effective alternatives for peripheral bypass if no GSV is available. Although there was a trend toward better results with the SSV, there was no significant difference between the 2 options.

Clinical Effectiveness and Resource Utilization of Surgery versus Endovascular Therapy for Chronic Limb-Threatening Ischemia. Ann Vasc Surg 2020; 68:510-521. [PMID: 32439522 DOI: 10.1016/j.avsg.2020.04.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Revised: 04/29/2020] [Accepted: 04/30/2020] [Indexed: 11/15/2022]
Abstract
BACKGROUND The clinical effectiveness of surgical versus endovascular therapy for chronic limb-threatening ischemia (CLTI) continues to be debated, and the resources required for each therapy are unclear. METHODS Systematic review of randomized controlled trials (RCTs) and observational studies comparing surgery with endovascular therapy for CLTI, which reported clinical effectiveness and resource utilization. Short-term and long-term clinical outcomes were examined. RESULTS The search yielded 4,231 titles, of which 17 publications met our inclusion criteria. Five publications were all from 1 RCT, and 12 publications were observational studies. In the RCT, the surgical approach had greater resource use in the first year (total hospital days across all admissions for surgery versus angioplasty: 46.14 ± 53.87 vs. 36.35 ± 51.39; P < 0.001; also true for days in high-dependency and intensive therapy units), but differences were not statistically significant in subsequent years. All-cause mortality presented a nonsignificant difference favoring angioplasty in the first 2 years (adjusted hazard ratio [aHR], 1.27; 95% confidence interval [95% CI], 0.75-2.15), but after 2 years, it favored surgical treatment (aHR, 0.34; 95% CI, 0.17-0.71). The observational studies reported short-term effectiveness and resource utilization favoring endovascular therapy, but most differences were not statistically significant. Long-term outcomes were more mixed; in particular, mortality outcomes generally favored surgery, although concluding that cause and effect is not possible as endovascularly treated patients tended to be older and may have had a shorter life expectancy regardless of therapy. CONCLUSIONS The clinical effectiveness and resource utilization of surgery compared with endovascular therapy for CLTI is not known with certainty and will not be known until ongoing trials report results. It is likely that findings will vary by the time horizon, where initial outcomes and utilization tend to favor endovascular interventions, but long-term outcomes favor surgical revascularization.

Abstract
Purpose: To determine in a chronic limb-threatening ischemia (CLTI) population who underwent endovascular therapy (EVT) how many patients would have been categorized as preferred for bypass surgery according to the Global Vascular Guidelines (GVG) and ascertain their surgical risk. Materials and Methods: The current study analyzed 1043 CLTI patients who presented WIfI (wound, ischemia, and foot infection) stage ≥2 and underwent EVT between April 2010 and December 2017. Of these, 176 were excluded for lack of angiographic or other data, leaving 867 CLTI patients (mean age 74±10 years; 523 men) for stratification according to the GVG into bypass-preferred, indeterminate, or EVT-preferred groups. The GVG recommend bypass as the first-line treatment when the wound is severe (WIfI stage ≥3) and lesions are complex (GLASS stage III). Surgical risk was estimated using the modified PREVENT III risk score. To further stratify the bypass-preferred population according to mortality risk, a survival decision tree was constructed using recursive partitioning. Results: The bypass-preferred group accounted for 55% [95% confidence interval (CI) 51% to 58%] of the overall population. The decision tree analysis extracted a low-mortality risk subgroup with a survival rate of 99% (95% CI 98% to 100%) at 1 month and 80% (95% CI 73% to 87%) at 2 years. According to the PREVENT III score, 34% (95% CI 27% to 42%) of the low mortality risk subgroup were classified as high surgical risk. Conclusion: A high proportion of patients undergoing EVT were considered bypass preferred based on the GVG, and the survival of these patients was not significantly different whether they were high or low surgical risk.

J Vasc Interv Radiol 2020; 31:202-212.

Abstract
A formal systematic review and study-level meta-analysis of randomized controlled trials investigating treatment of the infrapopliteal arteries with paclitaxel-coated balloons compared with conventional balloon angioplasty for critical limb ischemia (CLI) was conducted. Medical databases and online content were last screened in September 2019. The primary safety and efficacy endpoint was amputation-free survival defined as freedom from all-cause death and major amputation. Target lesion revascularization (TLR) constituted a secondary efficacy endpoint. Summary effects were synthesized with a random-effects model. Some 8 randomized controlled trials with 1,420 patients (97% CLI) were analyzed up to 1 year follow-up. Amputation-free survival was significantly worse in case of paclitaxel (13.7% crude risk of death or limb loss compared to 9.4% in case of uncoated balloon angioplasty; hazard ratio 1.52; 95% confidence interval: 1.12-2.07, p = .008). TLR was significantly reduced in case of paclitaxel (11.8% crude risk of TLR versus 25.6% in control; risk ratio 0.53; 95% confidence interval: 0.35-0.81, p = .004). The harm signal was evident when examining the high-dose (3.0-3.5 μg/mm2) devices, but attenuated below significance in case of a low-dose (2.0 μg/mm2) device. Actual causes remain largely unknown, but non-target paclitaxel embolization is a plausible mechanism.

Abstract
The purpose of this study was to evaluate the amputation-free survival rate and predictors of major adverse cardiovascular events (extracardiac and cardiac mortality, non-fatal myocardial infarction, non-fatal stroke) in patients with atherosclerotic occlusive-stenotic lesions of the femoropopliteal-tibial segment and critical ischaemia. We analysed the results of treating a total of 122 patients with atherosclerotic lesions of the superficial femoral artery and lower limb critical ischaemia. Of these, 35 patients had no lesions of other arterial basins, 24 patients presented with a concomitant lesion of the carotid basin, 41 subjects had lesions of the coronary basin, and 22 had lesions of the coronary and carotid basins. The patients were subjected to either bypass graft operation (n=75) or endovascular intervention (n=47). The evaluated outcome measures were amputation-free survival and the frequency of major adverse cardiovascular events. The average duration of follow up amounted to 38.2±4.3 months. The carried out multivariate logistic regression analysis demonstrated that the factors associated with lower limb amputation and the development of major adverse cardiovascular events were as follows: a concomitant lesion of the coronary (p=0.044) and coronary-carotid (p<0.05) basins, a history of endured myocardial infarction (p=0.003), a C-reactive protein level not less than 17.0 mg/l (p<0.05) and the value of the apolipoprotein B/A1 ratio above 1.0 (p=0.004).
