Abstract
BACKGROUND Endovascular interventions in infrapopliteal occlusive artery disease are becoming more complex, and this frequently tests the standard method of treatment, plain old balloon angioplasty (POBA). The potential that serration angioplasty could produce a more acceptable tibial artery lumen was assessed in this study. AIM The aim of this single-center subgroup analysis was to compare acute angiographic results after endovascular treatment using the Serranator serration balloon catheter in patients participating in the PRELUDE-BTK trial with POBA of the infrapopliteal arteries. A secondary objective was to assess post-treatment hemodynamic improvements. METHODS Our center enrolled 15 subjects and treated 17 lesions within the multicenter prospective core laboratory-adjudicated PRELUDE-BTK study. A 25 lesions analyzed separately were treated with POBA and then compared with the Serranator subset. In both cohorts, lesions were treated with either plain angioplasty or Serranator as a stand-alone therapy; subsequent methods, such as drug elution technologies, were not used. Acute angiographic results were analyzed by the SynvaCor angiographic core laboratory. To assess volumetric flow rates, data were analyzed with a fluid flow simulation software and compared against Poiseuille's Law. RESULTS Final residual stenosis was 17.2%±8.2% in the Serranator group versus 33.7%±15.7% in the POBA group. The mean lumen diameter (MLD) gain for the Serranator group and the POBA group was 1.64±0.41 mm and 1.33±0.63 mm, respectively. The average atmospheric balloon inflation pressure was 5 ATM in the Serranator group versus 9 ATM in the POBA group. Neither group required a bailout stent; however, it was notable that there were significantly more chronic total occlusions (CTOs) treated in the Serranator group at 41.2% versus 12% in the POBA group. Regarding the effectiveness in improving hemodynamic blood flow for non-CTO lesions, the calculated average ratio of post-treatment to pre-treatment flow rates in the Serranator group was 238% than that for the POBA group. For CTO cases where pre-treatment flow rate was zero, final residual stenosis was used as the parameter for comparison. The Serranator group showed a 62% improvement in final residual stenosis over POBA. CONCLUSION Endovascular treatment of the infrapopliteal arteries by use of the Serranator serration balloon provides a novel and promising method of action compared with standard balloon angioplasty and, thus, may have a leading role in complex below-the-knee arterial lesions. CLINICAL IMPACT The Serranator device might help to adequately address issues with conventional routine techniques for the treatment of complex lesions in infrapopliteal arteries in patients with advanced stages of PAD and critical limb ischemia. Integrating modern technologies such as the Serranator balloon catheter into clinical routine is mandatory in order to gain a more favorable outcome in these severely diseased patients and, particularly, to reduce mortality and morbidity.

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 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
OBJECTIVE The aim of the study was to evaluate the outcome of first line hybrid treatment in patients with chronic limb threatening ischemia (CLTI) and to evaluate possible predictors of primary patency (PP) loss and limb clinical improvement (LCI). METHODS This was a retrospective non-randomized study. All patients underwent one-stage hybrid common femoral artery (CFA) endarterectomy combined with an inflow and/or outflow endovascular revascularization procedure. Demographic, clinical, and lesion characteristics for each patient were reported. Primary patency analysis was performed using Kaplan-Meier life tables, and univariate and multivariate analysis was used to assess possible predictors of PP loss and clinical improvement. RESULTS Complete data were obtained from 132 patients. Patients were divided into two groups according to their Rutherford's category (RC), group 1 (Rutherford 4) and group 2 (Rutherford 5 and 6). Technical success was 98%. The overall surgical peri-operative complication rate was 8%. At a mean follow-up of 32 ± 23 months, the rate of major adverse limb events (MALE) was 30%; only the rate of major amputation between two groups was significant statistically different (p = .006). Group 1 had significantly lower amputation rate at 36 months (p = .01). The presence of high iliac peripheral artery calcium scoring system (PACCS) grade (HR 9.43, 95% CI 2.40-36.9, p = .001), the poor run-off of leg vessels (HR 0.15, 95% CI 0.02-0.92, p = .04), and undergoing CFA endarterectomy combined with outflow endovascular revascularization procedure (HR 4.25, 95% CI 1.07-16.89, p = .04) were independent predictors of PP loss, while severe iliac artery stenosis (OR 0.09, 95% CI 0.02-0.32, p = <.001) and the presence of pre-operative patent leg vessels (OR 8.03, 95% CI 2015-29.95, p = .002) were the significant independent predictors of LCI. CONCLUSION The use of hybrid first line approach in patients with CLTI is a safe and feasible technique. From the analysis of the current study, it is clear that any effort should be made to achieve as many patency leg vessels as possible in order to obtain better and longer lasting clinical outcomes.

Abstract
We retrospectively reviewed the cases in which complications occurred during below-the-knee (BTK) endovascular treatments that were performed at our hospital from 2005 to 2014. Several interesting cases have been described herein. All the patients had diabetes and non-healing wounds on their feet and/or rest pain in their foot or leg, and therefore, endovascular treatment was performed for the BTK arteries of the affected lower extremity. The complications that occurred during the procedure were classified into six categories-vascular spasm, flow limiting dissection, perforation, broken guidewire, distal thromboembolism, and unusual puncture site bleeding. Each complication has its own solutions and management. We discuss these different classes of complications and describe how cases of each type were managed.

Midterm Outcomes of Common Femoral Endarterectomy Combined with Inflow and Outflow Endovascular Treatment for Chronic Limb Threatening Ischaemia. Eur J Vasc Endovasc Surg 2020; 59:947-955. [PMID: 32224037 DOI: 10.1016/j.ejvs.2020.02.028] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Revised: 02/06/2020] [Accepted: 02/28/2020] [Indexed: 01/26/2023]
Abstract
OBJECTIVE To assess mid term outcomes of common femoral endarterectomy combined with an inflow and outflow endovascular revascularisation procedure in patients with chronic limb threatening ischaemia (CLTI). METHODS This was a prospective study. All patients who, for the first time, underwent planned one stage hybrid common femoral artery (CFA) endarterectomy combined with an inflow and/or outflow endovascular revascularisation procedure to achieve limb salvage in patients with CLTI due to multilevel disease were included between January 2015 and May 2017. Demographics, and clinical and lesion characteristics for each patient were reported. The primary outcome was primary patency. Secondary outcomes were technical success, peri-operative morbidity and mortality, assisted primary patency, secondary patency, clinically driven target lesion revascularisation and amputation free survival. RESULTS Three groups were created according to the endovascular treatment zone: group 1 (inflow, n = 60); group 2 (outflow, n = 46); and group 3 (combined inflow and outflow, n = 53). CFA endarterectomy was a fixed step in all cases. The overall technical success was 98%. The peri-operative complication rate was 14% and the mortality rate was 2%. Patients in group 3 demonstrated a significantly lower primary patency rate (53.9% ± 7.1%; p < .001) at 24 months but improved secondary patency rate of (94.0% ± 3.4%). Based on the outcomes of the Cox regression multivariable analysis, lesion length (hazard ratio [HR] 1.10, 95% confidence interval [CI] 1.06-1.14; p < .001), chronic total occlusion (CTO) (HR 0.50, 95% CI 0.25-0.98; p = .046), peripheral artery calcium scoring system (PACSS) grade 4 (HR 2.44, 95% CI 1.27-4.68; p = .008), incomplete revascularisation (HR 3.32, 95% CI 1.64-6.73; p = .001), and dyslipidaemia (HR 0.50, 95% CI 0.27-0.93; p = .031) were the only significant independent predictors of loss of primary patency. CONCLUSION Common femoral endarterectomy combined with an inflow and outflow endovascular revascularisation procedure in patients with CLTI is safe, with acceptable patency rates, despite the need for secondary interventions. Dyslipidaemia, lesion length, CTO, PACSS grade 4, and incomplete revascularisation are independent predictors of primary patency loss. The current study analysis supports the recommendation to stage the procedure based on patient risk and degree of limb threat.

Abstract
The angiosome concept of foot perfusion was conceived based on anatomical studies of arterial circulation and used for planning surgical procedures, tissue reconstruction, and amputation. Its application is relevant in diabetic patients with critical limb ischemia and nonhealing foot ulcer or amputation. An understanding of foot angiosome anatomy is useful for predicting healing and planning arterial revascularization. A review of the literature, including the most recent systematic reviews and meta-analyses, indicates improved wound healing is achieved when the angiosome concept is followed. The greatest value of angiosome-based revascularization is in patients with lesion(s) limited to a single angiosome, or to achieve optimal healing of amputation sites. Future research should focus on proper identification of (imaging) modalities to determine the hemodynamic and functional changes before and after revascularization, thus identifying the "real" angiosome and directing optimal therapy.

Abstract
Objectives: The aim of this study is to investigate the impact of tibial runoff on outcomes of femoropopliteal interventions for atherosclerotic lesions. Methods: A retrospective review of 243 endovascular procedures for femoropopliteal atherosclerotic lesions on 243 limbs of 197 patients was performed. Results: The distribution rates of good tibial runoff (runoff score <7) and poor tibial runoff (runoff score ≥7) were 37.0% and 63.0%, respectively. In the poor tibial runoff group, the patients were older ( P = .019), and the proportion of male was lower ( P = .014). There was a significantly higher proportion of rest pain or tissue loss ( P < .001), and the prevalence of stroke ( P = .031) and renal insufficiency ( P = .005) was significantly higher in the poor runoff group. After femoropopliteal intervention, the amputation-free survival ( P = .03) and freedom from ischemia ( P = .003) were significantly lower in the poor runoff group. The interventions targeting below-the-knee (BTK) lesions performed concomitantly for critical limb ischemia or tissue loss with poor tibial runoff did not show a significant advantage in terms of freedom from ischemia; however, minor trends of longer lasting freedom from ischemia were observed when BTK intervention was combined. Conclusion: The patients with poor runoff showed significantly lower amputation-free survival and freedom from ischemia. In poor tibial runoff limbs with critical limb ischemia or tissue loss, BTK intervention did not demonstrate additional significant beneficial outcomes; however, there was a minor trend of longer lasting freedom from ischemia after concomitant BTK intervention.

Abstract
Objective Critical limb ischemia (CLI) is the most dangerous stage of peripheral artery disease (PAD). Many basic researches and clinical treatment had been focused on stem cell transplantation for CLI. This systematic review was performed to review evidence for safety and efficacy of autologous stem cell therapy in CLI. Methods A systematic literature search was performed in the SinoMed, PubMed, Embase, ClinicalTrials.gov, and Cochrane Controlled Trials Register databases from building database to January 2018. Results Meta-analysis showed that cell therapy significantly increased the probability of ulcer healing (RR = 1.73, 95% CI = 1.45–2.06), angiogenesis (RR = 5.91, 95% CI = 2.49–14.02), and reduced the amputation rates (RR = 0.59, 95% CI = 0.46–0.76). Ankle-brachial index (ABI) (MD = 0.13, 95% CI = 0.11–0.15), TcO2 (MD = 12.22, 95% CI = 5.03–19.41), and pain-free walking distance (MD = 144.84, 95% CI = 53.03–236.66) were significantly better in the cell therapy group than in the control group (P < 0.01). Conclusions The results of this meta-analysis indicate that autologous stem cell therapy is safe and effective in CLI. However, higher quality and larger RCTs are required for further investigation to support clinical application of stem cell transplantation.

Abstract
BACKGROUND Ischaemic ulcerations have been reported to persist and/or deteriorate despite technically successful revascularisations; a higher incidence of which affects patients with diabetes and critical limb ischaemia. In the context of wound healing, it is unclear if applications of the angiosome concept in 'direct revascularisation' (DR) would be able to aid the healing of chronic foot ulcerations better than the current 'best vessel' or 'indirect revascularisation' (IR) strategy in patients with co-morbid diabetes and critical limb ischaemia. METHODS A literature search was conducted in eight electronic databases, namely AMED, CINAHL, The Cochrane Library, ProQuest Health & Medicine Complete, ProQuest Nursing & Allied Health Source, PubMed, ScienceDirect and TRIP database. Articles were initially screened against a pre-established inclusion and exclusion criteria to determine eligibility and subsequently appraised using the Newcastle-Ottawa Scale. RESULTS Five retrospective studies of varying methodological quality were eligible for inclusion in this review. Critical analysis of an aggregated population (n = 280) from methodologically stronger studies indicates better wound healing outcomes in subjects who had undergone DR as compared to IR (p < 0.001; p = 0.04). DR also appears to result in a nearly twofold increase in probability of wound healing within 12 months (hazard ratio, 1.97; 95% CI, 1.34-2.90). This suggests that achieving direct arterial perfusion to the site of ulceration may be important for the healing of chronic diabetic foot ulcerations. CONCLUSION Incorporating an angiosome-directed approach in the lower limb revascularisation strategy could be a very useful adjunct to a solely indirect approach, which could increase the likelihood of wound healing. With the limited data currently available, findings appear promising and merit from further investigation. Additional research to form a solid evidence base for this revised strategy in patients with co-morbid diabetes and critical limb ischaemia is warranted.

Abstract
Purpose: To analyze the relationship between the new TransAtlantic Inter-Society Consensus (TASC II) infrapopliteal classification and limb outcomes among patients with critical limb ischemia (CLI). Methods: A single-center retrospective study was performed on 166 consecutive CLI patients (mean age 71 years; 113 men) undergoing endovascular treatment of 244 infrapopliteal lesions from 2006 to 2013. Patient, procedural, angiographic, and limb outcomes were compared for the new TASC A/B vs C/D classification for infrapopliteal lesions. Binary restenosis was determined by a peak systolic velocity ratio >2.0 by duplex ultrasound on follow-up at 1, 3, 6, and 12 months. Results: Seventy-two (43.4%) patients had TASC A/B lesions, while 94 (56.6%) had TASC C/D patterns of infrapopliteal disease. Baseline demographics and tissue loss (93% vs 94%, p=0.59) were similar between the groups. TASC A/B lesions were shorter (53±35 vs 170±83 mm, p<0.001), less severely stenosed (77%±24% vs 93%±14%, p<0.001), had a larger target vessel diameter (2.9±0.5 vs 2.6±0.5 mm, p<0.001), and were less frequently chronic total occlusions (24% vs 64%, p<0.001) compared with the TASC C/D group. Three-year freedom from both amputation (85% vs 67%, p=0.02) and major adverse limb events (79% vs 61%, p=0.02) were significantly higher in the TASC A/B group. Technical success rates (95% vs 80%, p<0.001) and 1-year primary patency (58% vs 51%, p=0.04) were higher in the A/B group. Overall 3-year survival was similar between the groups (96% A/B vs 88% C/D, p=0.2). Conclusion: TASC C/D infrapopliteal lesions are associated with higher amputation and major adverse limb events rates and lower primary patency compared with TASC A/B infrapopliteal lesions. Further studies are needed to assess the association between TASC C/D infrapopliteal lesions and clinical outcomes in patients with CLI.
