Abstract
OBJECTIVE Restenosis and late occlusion remain a significant problem for endovascular treatment of peripheral artery disease. This meta-analysis aims to evaluate the effect of cilostazol on late outcomes after endovascular repair of occlusive femoropopliteal disease. METHODS A systematic literature review was conducted conforming to established criteria to identify articles published up to September 2023 evaluating late outcomes after endovascular treatment for atherosclerotic femoropopliteal disease. Eligible studies should compare outcomes between patients treated with cilostazol and patients not treated with cilostazol. Both prospective and retrospective studies were eligible. Late outcomes included primary patency (PP), restenosis, target lesion revascularization (TLR), and major amputation during follow-up. RESULTS Overall, 10 clinical studies were identified for analysis including 4721 patients (1831 with cilostazol vs 2890 without cilostazol) that were treated for 5703 lesions (2235 with cilostazol vs 3468 without cilostazol). All studies were performed in Japan. Mean follow-up was 24.1 ± 12.5 months. Cilostazol was associated with a lower risk for restenosis (pooled odds ratio [OR], 0.503; 95% confidence interval [CI], 0.383-0.660; P < .0001). However, no association was found between cilostazol and TLR (pooled OR, 0.918; 95% CI, 0.300-2.812; P = .881) as well as major amputation (pooled OR, 1.512; 95% CI, 0.734-3.116; P = .263). Regarding primary patency, cilostazol was associated with a higher 12-month PP (OR, 3.047; 95% CI, 1.168-7.946; P = .023), and a higher 36-month PP (OR, 1.616; 95% CI, 1.412-1.850; P < .0001). No association was found between cilostazol and mortality during follow-up (pooled OR, .755; 95% CI, 0.293-1.946; P = .561). CONCLUSIONS Cilostazol seems to have a positive effect on 1- to 3-year PP and restenosis rates among patients treated endovascularly for atherosclerotic femoropopliteal disease. A positive effect on TLR and amputation risk was not verified in this review.

Abstract
PURPOSE The purpose of this study is to assess the efficacy and safety of cilostazol prescription in patients with femoropopliteal peripheral artery disease (PAD) after endovascular therapy (EVT). MATERIALS AND METHODS We conducted a systematic review and meta-analysis of all studies reporting the outcomes of cilostazol after femoropopliteal EVT of PAD up to September 2022. Clinical outcomes of interest included primary patency, in-stent restenosis (ISR), vessel re-occlusion, freedom from target lesion revascularization (TLR), repeat revascularization, all-cause mortality, amputation, major adverse cardiovascular events (MACEs) and major adverse limb events (MALEs), and bleeding complication. RESULTS A total of 4 randomized controlled trials (RCTs) and 8 observational studies containing a total of 4898 patients met the inclusion criteria and were included in this systematic review and meta-analysis. We found that the use of cilostazol was associated with higher primary patency after femoropopliteal artery EVT (odds ratio [OR]=1.67, 95% confidence interval [CI]=1.50-1.87, p<0.001, I2=33.2%), a lower risk of ISR (OR=0.43, 95% CI=0.29-0.63, p<0.001, I2=37.6%), repeat revascularization (OR=0.43, 95% CI=0.24-0.76, p<0.005, I2=27.4%), and vessel re-occlusion (OR=0.59, 95% CI=0.38-0.93, p<0.05, I2=0%). There was an increase in freedom from TLR rate (OR=2.19, 95% CI=1.58-3.05, p<0.001, I2=0%), as well as a reduction in the occurrence of MALEs (OR=0.50, 95% CI=0.29-0.85, p<0.05, I2=0%). However, there was no significant difference in amputation, MACEs, all-cause mortality, and major bleeding complications. Subgroup analysis showed that cilostazol treatment in patients with femoropopliteal drug-eluting stents (DES) implantation remained associated with higher primary patency and a lower risk of ISR. CONCLUSIONS After EVT of femoropopliteal artery lesions, additional oral cilostazol enhances primary patency, reduces the occurrences of ISR and vessel re-occlusion, diminishes the risks associated with MALEs, lowers the need for repeat revascularization, and increases freedom from TLR rates. However, it does not impact amputation, MACEs, all-cause mortality, or major bleeding complications. These findings suggest cilostazol as a potentially safe and effective adjunct therapy in patients with femoropopliteal PAD after EVT. CLINICAL IMPACT After undergoing endovascular therapy (EVT) for femoropopliteal artery lesions, the addition of cilostazol to antiplatelet therapy can significantly improve primary patency, reducing the incidence of in-stent restenosis, repeat revascularization, vessel re-occlusion, and major adverse limb events while increasing freedom from target lesion revascularization rate. The simultaneous use of drug-eluting stents in the femoropopliteal artery lesions, combined with cilostazol, potentially results in a synergistic anti-stenotic effect. This therapeutic approach does not appear to be associated with an increased risk of major bleeding events or all-cause mortality. These findings provide additional evidence supporting the treatment of anti-stenosis in patients with femoropopliteal artery lesions after EVT.

Abstract
Cilostazol is a quinolinone-derivative selective phosphodiesterase inhibitor and is a platelet-aggregation inhibitor and arterial vasodilator for the symptomatic treatment of intermittent claudication (IC). Cilostazol has been shown to improve walking distance for patients with moderate to severe disabling intermittent claudication who do not respond to exercise therapy and who are not candidates for vascular surgical or endovascular procedures. Several studies evaluated the pharmacological effects of cilostazol for restenosis prevention and indicated a possible effect on re-endothelialization mediated by hepatocyte growth factor and endothelial precursor cells, as well as inhibiting smooth muscle cell proliferation and leukocyte adhesion to endothelium, thereby exerting an anti-inflammatory effect. These effects may suggest a potential effectiveness of cilostazol in preventing restenosis and promoting the long-term outcome of revascularization interventions. This review aimed to point out the role of cilostazol in treating patients with peripheral arterial disease, particularly with IC, and to explore its possible role in restenosis after lower limb revascularization.

Abstract
Atherosclerotic cardiovascular disease (ASCVD) stands as the leading global cause of mortality. Addressing this vital and pervasive condition requires a multifaceted approach, in which antiplatelet intervention plays a pivotal role, together with antihypertensive, antidiabetic, and lipid-lowering therapies. Among the antiplatelet agents available currently, cilostazol, a phosphodiesterase-3 inhibitor, offers a spectrum of pharmacological effects. These encompass vasodilation, the impediment of platelet activation and aggregation, thrombosis inhibition, limb blood flow augmentation, lipid profile enhancement through triglyceride reduction and high-density lipoprotein cholesterol elevation, and the suppression of vascular smooth muscle cell proliferation. However, the role of cilostazol has not been clearly documented in many guidelines for ASCVD. We comprehensively reviewed the cardiovascular effects of cilostazol within randomized clinical trials that compared it to control or active agents and involved individuals with previous coronary artery disease or stroke, as well as those with no previous history of such conditions. Our approach demonstrated that the administration of cilostazol effectively reduced adverse cardiovascular events, although there was less evidence regarding its impact on myocardial infarction. Most studies have consistently reported its favorable effects in reducing intermittent claudication and enhancing ambulatory capacity in patients with peripheral arterial disease. Furthermore, cilostazol has shown promise in mitigating restenosis following coronary stent implantation in patients with acute coronary syndrome. While research from more diverse regions is still needed, our findings shed light on the broader implications of cilostazol in the context of atherosclerosis and vascular biology, particularly for individuals at high risk of ASCVD.

Abstract
OBJECTIVES Cilostazol is used for the treatment of intermittent claudication. The impact of cilostazol on the outcomes of peripheral vascular interventions (PVI) remains controversial. This study assesses the use and impact of cilostazol on patients undergoing PVI for peripheral arterial disease (PAD). METHODS The Vascular Quality Initiative (VQI) database files for PVI were reviewed. Patients with PAD who underwent PVI for CLTI or claudication were included and divided based on the use of cilostazol preoperatively. After propensity matching for patient demographics and comorbidities, the short-term and long-term outcomes of the two groups (preoperative cilostazol use versus no pre-operative cilostazol use) were compared. The Kaplan-Meier method was used to determine outcomes. RESULTS A total of 245,309 patients underwent PVI procedures and 6.6% (N=16,366) were on cilostazol prior to intervention. Patients that received cilostazol were more likely to be male (62% vs 60%; P < .001), White (77% vs 75%; P < .001), and smokers (83% vs 77%; P < .001). They were less likely to have diabetes mellitus (50% vs 56%; P < .001) and congestive heart failure (14% vs 23%; P < .001). Patient on cilostazol were more likely to be treated for claudication (63% vs 40%, P < .001), undergo prior lower extremity revascularization (55% vs 51%, P<.001) and less likely to have undergone prior minor and major amputation (10% vs 19%; P < .001) compared to patients who did not receive cilostazol. After 3:1 propensity matching, there were 50,265 patients included in the analysis with no differences in baseline characteristics. Patients on cilostazol were less likely to develop renal complications and more likely to be discharged home. Patients on cilostazol had significantly lower rates of long-term mortality (11.5% vs 13.4%, P <.001 and major amputation (4.0% vs 4.7%, P=0.022). However, there were no significant differences in rates of reintervention, major adverse limb events, or patency after PVI. Amputation-free survival rates were significantly higher for patients on cilostazol, after four years of follow-up (89% vs 87%, P=0.03). CONCLUSION Cilostazol is underutilized in the VQI database and seems to be associated with improved amputation-free survival. Cilostazol therapy should be considered in all patients with PAD who can tolerate it prior to PVI.

Abstract
OBJECTIVES The effectiveness of postoperative medication for the prevention of late graft failure is controversial. We conducted the present study to investigate whether cilostazol improved the mid-term outcomes after infrainguinal autologous vein bypass for chronic limb-threatening ischemia (CLTI). METHODS From April 1994 to March 2022, we performed 590 de novo infrainguinal bypass procedures using autologous vein grafts (AVGs) in three hospitals. The bypass grafts were classified according to the postoperative prescription of cilostazol. The loss of graft patency and major adverse limb events (MALEs) were set as endpoints. Patients who died within 30 days and grafts that lost primary patency within 30 days after surgery were excluded. Data up to 3 years were analyzed. The cumulative primary patency (PP), assisted primary patency (AP), secondary patency (SP), and freedom from MALE (ffMALE) rates were calculated by the Kaplan-Meier method and compared between the cilostazol group and the non-cilostazol group. After a propensity score matching, same statistical analyses were performed. In addition, a Cox proportional hazards regression analysis that included preoperative factors, intraoperative factors, and postoperative medications was performed to identify whether cilostazol is an independent predictor for the outcomes. RESULTS A total of 523 AVGs met inclusion criteria. Kaplan-Meier curves showed that the cilostazol group was superior to the non-cilostazol group in all outcomes, while the cilostazol group was superior to the non-cilostazol group in AP and SP after a propensity score matching. A multivariable analysis showed that non-use of cilostazol was identified as an independent predictor for loss of AP, SP, and ffMALE. CONCLUSIONS Cilostazol improved the mid-term outcomes after infrainguinal autologous vein bypass.

Abstract
Symptoms of lower-extremity artery disease (LEAD) emerge from impaired vascularization in distal circulation of the extremities. Calcium channel blockers (CCB) can improve distal circulation when used as adjunctive therapy with endovascular treatment (EVT), but few studies have evaluated that. We investigated the relationship between CCB therapy and post-EVT outcomes. Through a consecutive EVT registry, we evaluated those relationships in whole cohort and the following 2 subgroups; the patients suffered from intermittent claudication (IC) or chronic limb-threatening ischemia (CLTI), with adjusting baseline characteristics by propensity score matchings. The primary endpoints were major adverse cardiac and cerebrovascular events (MACCE, a composite endpoint of all death, nonfatal myocardial infarction, and nonfatal stroke), and major adverse limb event (MALE, a composite of major amputation, acute limb ischemia, and surgical reintervention). The group that received CCB had less MALE in whole cohort (HR 0.31; 95% confidence interval (CI) 0.20-0.47), and less MACCE and MALE in CLTI cohort (HR 0.67; 0.50-0.89 and 0.32; 0.20-0.52 respectively) compared to the group that did not receive CCB. The relationships were common in the cohorts with baseline adjustment. MACCE and MALE in IC (HR 1.01; 0.57-1.80 and 0.60; 0.25-1.45, respectively) showed no significant differences both with and without baseline adjustment. CCB use was related to fewer MACCE and MALE events in adjusted patients who underwent EVT, and the trend was more evident, especially in the adjusted CLTI cohort. This study highlights the necessity of future studies regarding CCB. Clinical Trial Registration: URL: https://www.umin.ac.jp ; Unique identifiers: UMIN000015100.

Abstract
Optimal antiplatelet therapy after endovascular therapy (EVT) for peripheral artery disease is controversial. This trial aimed to evaluate whether sarpogrelate plus aspirin was non-inferior for preventing early restenosis after femoropopliteal (FP) EVT compared to clopidogrel plus aspirin. In this open-label, prospective randomized trial, 272 patients were enrolled after successful EVT for FP lesions. Patients in each group received aspirin 100 mg and clopidogrel 75 mg or sarpogrelate 300 mg orally once per day for 6 months. The primary outcome was target lesion restenosis at 6 months, tested for noninferiority. Patient characteristics and EVT patterns were similar, except for increased inflow procedures in the sarpogrelate group and increased outflow procedures in the clopidogrel group. The sarpogrelate group showed a tendency of less restenosis at 6 months than the clopidogrel group (13.0% vs. 19.1%, difference 6.1 percentage points, 95% CI for noninferiority - 0.047 to 0.169). Secondary endpoints related to safety outcomes were rare in both groups. Risks of target lesion restenosis of the two intervention arm were uniform across most major subgroups except for those with coronary artery disease. In conclusion, Sarpogrelate plus aspirin is non-inferior to clopidogrel plus aspirin in preventing early restenosis after FP EVT. Larger multi-ethnic trials are required to generalize these findings.

Abstract
ZusammenfassungPatienten mit peripherer arterieller Verschlusskrankheit (pAVK) oder Aortenerkrankungen haben ein hohes Risiko für kardiovaskuläre Ereignisse. Gerinnungshemmende Medikamente verbessern die
Prognose und haben daher einen hohen Stellenwert. Bei jeder gerinnungshemmenden Therapie sollte das individuelle Blutungsrisiko berücksichtigt werden und eine individuelle
Nutzen-Risiko-Abwägung durchgeführt werden. Patienten mit symptomatischer pAVK sollten einen Thrombozytenaggregationshemmer (TZAH) erhalten. Bei hohem Risiko für kardiovaskuläre Ereignisse
und niedrigem Blutungsrisiko wird die Kombination von Acetylsalicylsäure (ASS) 100 mg und Rivaroxaban 2 × 2,5 mg empfohlen. Liegt ein hohes Blutungsrisiko vor, ist Clopidogrel ASS
vorzuziehen. Bei Patienten mit Aortenerkrankungen (z. B. komplexe Plaques, Aortenaneurysma) ist die Gabe eines TZAH indiziert. Patienten mit einer atherosklerotischen Gefäßerkrankung und
Indikation für eine orale Antikoagulation wegen Vorhofflimmern oder venöser Thromboembolie sollten keinen zusätzlichen TZAH erhalten. Denn dieser erhöht das Blutungsrisiko, ohne die Prognose
zu verbessern.

Abstract
Background Patients with peripheral arterial disease (PAD) are at increased risk for major adverse cardiovascular events (MACE) such as cardiovascular death, myocardial infarction, and stroke as well as major adverse limb events (MALE) such as amputation and acute limb ischemia. Therefore, prevention of thrombotic events is crucial to improve the prognosis of PAD patients. This review article concludes current evidence and guideline recommendations about antithrombotic therapy in PAD patients.Antithrombotic therapy is highly effective to reduce MACE and MALE events in PAD patients. Recently, the concept of dual pathway inhibition (low-dose rivaroxaban plus acetylic salicylic acid (ASA) has been tested in the COMPASS and VOYAGER-PAD trial. Compared to ASA alone dual pathway inhibition was superior to prevent MACE and MALE. After peripheral revascularization, in particular the risk for acute limb ischemia was reduced. In contrast, the risk for major bleeding is increased. Therefore, current guidelines recommend the combination of low-dose rivaroxaban and ASA in PAD patients with low bleeding risk. In patients with high bleeding risk, a single antiplatelet drug (preferable clopidogrel) is indicated. In patients with atherosclerotic vascular disease and indication for oral anticoagulation, no additional antiplatelet drug is necessary, as this would increase the risk of bleeding without improving the prognosis. Conclusion Antithrombotic treatment reduces MACE and MALE and is recommended in all patients with PAD. Individual bleeding risk should always be considered based on the current data situation and an individual benefit-risk assessment must be carried out.

Abstract
Background High-quality evidence from trials directly comparing single antiplatelet therapies in symptomatic peripheral arterial disease (PAD) to dual antiplatelet therapies or acetylsalicylic acid (ASA) plus low-dose rivaroxaban is lacking. Therefore, we conducted a network meta-analysis on the effectiveness of all antithrombotic regimens studied in PAD. Methods A systematic search was conducted to identify randomized controlled trials. The primary endpoints were major adverse cardiovascular events (MACE) and major bleedings. Secondary endpoints were major adverse limb events (MALE) and acute limb ischaemia (ALI). For each outcome, a frequentist network meta-analysis was used to compare relative risks (RRs) between medication and ASA. ASA was the universal comparator since a majority of studies used ASA as in the reference group. Results Twenty-four randomized controlled trials were identified including 48,759 patients. With regard to reducing MACE, clopidogrel [RR 0.78, 95% confidence interval (CI) 0.66–0.93], ticagrelor (RR 0.79, 95% CI 0.65–0.97), ASA plus ticagrelor (RR 0.79, 95% CI 0.64–0.97), and ASA plus low-dose rivaroxaban (RR 0.84, 95% CI 0.76–0.93) were more effective than ASA, and equally effective to one another. As compared to ASA, major bleedings occurred more frequently with vitamin K antagonists, rivaroxaban, ASA plus vitamin K antagonists, and ASA plus low-dose rivaroxaban. All regimens were similar to ASA concerning MALE, while ASA plus low-dose rivaroxaban was more effective in preventing ALI (RR 0.67, 95% CI 0.55–0.80). Subgroup analysis in patients undergoing peripheral revascularization revealed that ≥ 3 months after intervention, evidence of benefit regarding clopidogrel, ticagrelor, and ASA plus ticagrelor was lacking, while ASA plus low-dose rivaroxaban was more effective in preventing MACE (RR 0.87, 95% CI 0.78–0.97) and MALE (RR 0.89, 95% CI 0.81–0.97) compared to ASA. ASA plus clopidogrel was not superior to ASA in preventing MACE ≥ 3 months after revascularization. Evidence regarding antithrombotic treatment strategies within 3 months after a peripheral intervention was lacking. Conclusion Clopidogrel, ticagrelor, ASA plus ticagrelor, and ASA plus low-dose rivaroxaban are superior to ASA monotherapy and equally effective to one another in preventing MACE in PAD. Of these four therapies, only ASA plus low-dose rivaroxaban provides a higher risk of major bleedings. More than 3 months after peripheral vascular intervention, ASA plus low-dose rivaroxaban is superior in preventing MACE and MALE compared to ASA but again at the cost of a higher risk of bleeding, while other treatment regimens show non-superiority. Based on the current evidence, clopidogrel may be considered the antithrombotic therapy of choice for most PAD patients, while in patients who underwent a peripheral vascular intervention, ASA plus low-dose rivaroxaban could be considered for the long-term (> 3 months) prevention of MACE and MALE.

Abstract
Chronic deep venous disease (CVD) can result in significant morbidity and impact on quality of life due to a spectrum of symptoms, including lower extremity edema, venous claudication, and venous ulcers. CVD can be secondary to both thrombotic and nonthrombotic disease processes, including postthrombotic syndrome from prior deep vein thrombosis (DVT) or iliac vein compression syndrome. Endovascular therapy has become a mainstay therapy for CVD patients, with venous stent placement frequently performed. However, the management of anticoagulation following venous stent placement is not well-studied, with no large trials or consensus guidelines establishing an optimal regimen. The current knowledge gap in antithrombotic therapy is magnified by heterogeneity in practice and data collection, along with incomplete reporting in available studies. Furthermore, most published datasets are antiquated in the setting of rapid evolution in technique and technology available for deep venous intervention. Herein, we summarize the current available literature and offer an approach to anticoagulation and antiplatelet management following deep venous intervention for CVD.

Cilostazol effectiveness in reducing drug-coated stent restenosis in the superficial femoral artery: The ZERO study. PLoS One 2022; 17:e0270992. [PMID: 35797395 PMCID: PMC9262206 DOI: 10.1371/journal.pone.0270992] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Accepted: 06/11/2022] [Indexed: 11/26/2022] Open
Abstract
Purpose Drug-eluting stents (DESs) play an important role in endovascular therapy (EVT) for femoropopliteal (FP) lesions. Cilostazol improves patency after bare-metal nitinol stent (BNS) implantation for femoropopliteal lesions. This study aimed to establish whether cilostazol is effective in improving the patency of DESs and determine whether BNS or DESs with or without cilostazol are more effective in improving the 12-month patency after EVT for FP lesions. Materials and methods In this prospective, open-label, multicenter study, 85 patients with symptomatic peripheral artery disease due to de novo FP lesions were enrolled and treated with DESs with cilostazol from eight cardiovascular centers between April 2018 and May 2019. They were compared with 255 patients from the DEBATE SFA study, in which patients were randomly assigned to the BNS, BNS with cilostazol, or DES groups. The primary endpoint was the 12-month patency rate using duplex ultrasound (peak systolic velocity ratio < 2.5). This study was approved by the ethics committee of each hospital. Results The 12-month patency rates for the BNS, BNS with cilostazol, DES, and DES with cilostazol groups were 77.6%, 93.1%, 82.8%, and 94.2%, respectively (p = 0.007). The 12-month patency rate was higher in the DES with cilostazol group than in the DES group (p = 0.044). In small vessels, the DES with cilostazol group had a higher patency rate than the DES group (100.0% vs. 83.4%, p = 0.023). Conclusions DES with cilostazol showed better patency than DES alone. Cilostazol improved patency after EVT with DES in FP lesions and small vessels. Clinical trial registration University Hospital Medical Information Network Clinical Trials Registry (no.

Abstract
Endovascular treatment (EVT) is the main treatment for peripheral artery disease (PAD). Despite advances in device development, the restenosis rate remains high in patients with femoropopliteal lesions (FP). This study aimed to evaluate the effectiveness of exercise training in reducing the 1-year in-stent restenosis rate of bare metal nitinol stents for FPs. This prospective, randomized, open-label, multicenter study was conducted from January 2017 to March 2019. We randomized 44 patients who had claudication with de novo stenosis or occlusion of the FP into an intensive exercise group (n = 22) and non-intensive exercise group (n = 22). Non-intensive exercise was defined as walking for less than 30 min per session, fewer than three times a week. We assessed exercise tolerance using an activity meter at 1, 3, 6, and 12 months, and physiotherapists ensured maintenance of exercise quality every month. The primary endpoint was instant restenosis defined as a peak systolic velocity ratio > 2.5 on duplex ultrasound imaging. Kaplan–Meier analysis was used to evaluate the data. There were no significant differences in background characteristics between the groups. Six patients dropped out of the study within 1 year. In terms of the primary endpoint, intensive exercise significantly improved the patency rate of bare nitinol stents at 12 months. The 1-year freedom from in-stent restenosis rates were 81.3% in the intensive exercise group and 47.6% in the non-intensive exercise group (p = 0.043). No cases of stent fracture were observed in the intensive exercise group. Intensive exercise is safe and reduces in-stent restenosis in FP lesions after endovascular therapy for PAD.

Abstract
Background This study was to assess the clinical outcome and associated parameters of endovascular therapy (EVT group) and bypass surgery (bypass group) in patients with long femoropopliteal TransAtlantic Inter-Society Consensus II (TASC II) C and D peripheral artery disease (PAD). Methods 187 patients who underwent successful EVT or bypass surgery were assessed. The endpoints included the events of cardiovascular disease (CVD) and lower-extremity amputation (LEA), 3-year primary patency, and 3-year amputation-free survival (AFS). Results The 3-year primary and secondary patency rates were better in the bypass group (P=0.007 and P=0.039, respectively), while the incidences of LEA, new CVD events, and mortality were comparable between groups. Weighted multivariate Cox analyses showed that cilostazol treatment (hazard ratio (HR): 0.46, 95% confidence interval (CI): 0.3–0.72, P=0.001), statin treatment (HR: 0.54, 95% CI: 0.33–0.9, P=0.014), and direct revascularization (DR) (HR: 0.47, 95% CI: 0.29–0.74, P=0.001) were predictive factors of 3-year primary patency. Kaplan–Meier curve analyses of time-to-primary cumulative AFS showed that nondiabetes mellitus, mild PAD, and cilostazol and statin treatment were correlated with a superior 3-year AFS (log rank test, P=0.001, P < 0.001, P=0.009, and P=0.044, respectively). Conclusions Endovascular stenting based on the angiosome concept and bypass surgery provide comparable benefits for the treatment of long, advanced femoropopliteal lesions after a short follow-up period, whereas cilostazol therapy for more than 3 months, aggressive treatment of dyslipidemia, and surgical revascularization were associated with higher primary patency.

Abstract
Although symptomatic peripheral arterial disease (PAD) is common in patients with hemodialysis (HD), few studies have evaluated the long-term clinical outcomes of revascularization in this population. The aim of the current study was to investigate the 10-year clinical outcomes of HD patients with PAD undergoing endovascular therapy (EVT). We retrospectively analyzed 750 limbs from 578 HD patients with symptomatic PAD due to infrainguinal lesions, treated with EVT, between May 2004 and November 2011. The primary outcome was 10-year mortality and the secondary outcome was 10-year freedom from major adverse limb events (MALEs). Predictors for each outcome were evaluated by Cox proportional-hazards model. The 10-year rate of survival and freedom from MALEs was 23.6 ± 3.1% and 76.4 ± 2.9%, respectively. In the multivariate analysis, patients with over 80 years [hazard ratio (HR) 2.10; 95% confidence interval (CI) 1.58-2.80; p < 0.001], non-ambulatory status (HR 1.55; 95% CI 1.19-2.03; p = 0.001), absence of hypertension (HR 1.59; 95% CI 1.19-2.08; p = 0.001), heart failure (HR 1.36; 95% CI 1.02-1.80; p = 0.03), and tissue loss (HR 1.65; 95% CI 1.28-2.12; p < 0.001) were at an increased risk of 10-year mortality. Cerebrovascular diseases (HR 1.60; 95% CI 1.03-2.49; p = 0.038), no cilostazol use (HR 1.69; 95% CI 1.09-2.70; p = 0.021), tissue loss (HR 3.87; 95% CI 2.37-6.34; p < 0.001), and poor below-the-knee (BTK) run-off (HR 1.68; 95% CI 1.04-2.71; p = 0.035) were significantly associated with MALEs. After risk stratification analysis based on risk score assignment according to number of predictors, 10-year survival and freedom from MALE were lower in the higher score groups (10-year survival rates according to number of risk factors: 0, 35.1%; 1, 20.3%; 2-5, 10.8%; respectively, p < 0.001, 10-year freedom from MALE rates in patients with greater number of risk factors: 0-1, 90.2%; 2-3, 65.5%; 4-5, 61.6%; respectively, p < 0.001). The 10-year clinical outcomes after EVT for HD patients with PAD due to infrainguinal disease were clinically suboptimal. Risk stratification based on these predictors before EVT would be useful in estimating future adverse outcome.

Abstract
Peripheral arterial disease (PAD) represents a major health issue that significantly impacts patient's survival and quality of life. In addition to limb-related events, patients with PAD have an increased risk of myocardial infarction, stroke, and death. However, compared with coronary and cerebrovascular disease, studies addressing optimal risk reduction modalities including antithrombotic therapies in patients with PAD have been underrepresented in the literature. This publication serves as a narrative review of existing evidence on the effectiveness of antithrombotic therapy in patients with PAD. In patients with chronic stable PAD or post-revascularization, antithrombotic therapies including single or dual antiplatelet agents, anticoagulation, or a combination of these treatments have been shown to reduce cardiovascular and limb events. This narrative review provides a summary of the available literature on the management of patients with PAD, categorized into treatment strategies for chronic, post-endovascular treatment, and post-open surgical revascularization and to discuss the antithrombotic protocol utilized at our institution while providing a rational for our treatment algorithm.

Abstract
Cilostazol, a phosphodiesterase III inhibitor, has vasodilating and antiplatelet properties with a low rate of bleeding complications. It has been used over the past 25 years for improving intermittent claudication in patients with peripheral artery disease (PAD). Cilostazol also has demonstrated efficacy in patients undergoing percutaneous revascularization procedures for both PAD and coronary artery disease. In addition to its antithrombotic and vasodilating actions, cilostazol also inhibits vascular smooth muscle cell proliferation via phosphodiesterase III inhibition, thus mitigating restenosis. Accumulated evidence has shown that cilostazol, due to its "pleiotropic" effects, is a useful, albeit underutilized, agent for both coronary artery disease and PAD. It is also potentially useful after ischemic stroke and is an alternative in those who are allergic or intolerant to classical antithrombotic agents (eg, aspirin or clopidogrel). These issues are herein reviewed together with the pharmacology and pharmacodynamics of cilostazol. Large studies and meta-analyses are presented and evaluated. Current guidelines are also discussed, and the spectrum of cilostazol's actions and therapeutic applications are illustrated.

Abstract
PURPOSE To identify the risk factors associated with patency loss after bailout stenting with third-generation hybrid heparin-bonded nitinol stent of the femoropopliteal segment. METHODS Prospective, multicenter, single-arm registry including 156 patients (50 females, mean age 72 ± 11 years) subjected, from February 2017 to December 2018, to provisional stenting with Gore Tigris vascular stent of the distal superficial femoral artery, with or without involvement of the popliteal artery, in 9 different centers. The 194 lesions, with Rutherford score ≥ 3, were stented in case of recoil, dissection or residual stenosis not responding to percutaneous trans-luminal angioplasty (PTA). The follow-up (FU) was performed with clinical evaluation and duplex ultrasound (DUS) at 1, 6 and 12 months. RESULTS The primary patency rate was 99(95%CI 98-100)% at 1 month, 86(80-92)% at 6 months and 81(74-88)% at-12 months. After patency loss, 13/23 (56.5%) patients were re-treated, yielding a primary assisted patency of 91(86-96)% at 6 months and 88(82-94)% at 12 months and a secondary patency of 94(90-98)% at 6 months and 90(84-95)% at 12 months. Rutherford score ≥ 4 (p = 0.03) and previous severe treatments (p = 0.01) were identified as risk factors for early patency loss during FU. The involvement of the popliteal artery was not an independent risk factor for loss of patency. CONCLUSIONS The bailout stenting of the femoropopliteal segment with third-generation nitinol stents is a safe and effective option in case of recoil, dissection or residual stenosis not responding to PTA. Critical limb ischemia and history of previous major treatment at the same level are significant prognostic factors for patency loss during FU.

Abstract
Peripheral artery disease (PAD) is one of the most frequent manifestations of atherosclerosis with high rates of morbidity and mortality. Platelets and coagulation are involved in the progression of atherosclerosis and thromboembolic complications. PAD patients have increased prothrombotic potential, which includes platelet hyperaggregability and increased pro-coagulant state. Therefore, antithrombotic treatment is of utmost importance for the prevention of cardiovascular events in this group of patients. Aspirin is the basic antiplatelet drug, but with limited efficacy in PAD. In contrast to coronary artery disease, its effect on the prevention of cardiovascular events in PAD has been limited proven. Particularly in asymptomatic PAD, there is no evidence for risk reduction with aspirin. Clopidogrel and ticagrelor are more effective than aspirin. Clopidogrel is thus an effective alternative to aspirin for prevention of cardiovascular events in symptomatic PAD. In patients who are non-responders to clopidogrel, ticagrelor is indicated. Dual antiplatelet treatment (DAPT) with aspirin and ticagrelor in patients with coronary artery disease and concomitant PAD significantly decreased the rate of major adverse cardiovascular events, including adverse limb events. However, in the CHARISMA Trial, aspirin and clopidogrel were not more effective than aspirin alone and increased bleeding complications. Therefore, DAPT seems effective only in PAD accompanied by coronary artery disease. Anticoagulant treatment for symptomatic PAD with vitamin K antagonists alone or in combination with aspirin is not more effective than single antiplatelet treatment but increases the rate of major bleeding. Low dose rivaroxaban combined with aspirin in PAD patients significantly reduces cardiovascular events, including limb-threatening ischemia and limb amputations. Anticoagulation and antiplatelet treatment after percutaneous or surgical revascularization of PAD improve the patency of treated vessels. Aspirin with or without dipyridamole improved patency of infra-inguinal by-pass grafts at one year. The combination of clopidogrel with aspirin was more effective than aspirin alone in the prevention of prosthetic graft occlusions in patients undergoing below-knee by-pass-grafting. Oral vitamin K antagonists were not more effective than aspirin in the prevention of infra-inguinal by-pass occlusion. The combination of low dose rivaroxaban and aspirin was effective in preventing major adverse cardiovascular events and adverse limb events after infrainguinal endovascular or surgical revascularization in patients with intermittent claudication. However, the data on antithrombotic treatment after revascularization for limb-threatening ischemia is scanty and inconclusive. In conclusion: Antithrombotic treatment of PAD is a cornerstone for the management of these patients. Antiplatelet drugs prevent the initiation and progression of atherosclerosis and are effective also in the prevention of thromboembolic events. Simultaneous use of antiplatelet and anticoagulation drugs is accompanied by an increased risk of bleeding. However, combined treatment with aspirin and low-dose rivaroxaban is more effective than single antithrombotic treatment and safer than full-dose combined treatment.

Abstract
Critical limb ischemia (CLI) constitutes the most advanced form of peripheral artery disease (PAD) and is characterized by ischemic rest pain, tissue loss and/or gangrene. Optimized medical care and risk factor modification in addition to revascularization could reduce the incidence of cardiovascular events and major adverse limb events, improving patients' quality of life and promising higher survival rates. Adequate adherence to cardioprotective medications, including antithrombotic therapy (e.g., antiplatelets, anticoagulants), cholesterol-lowering agents (e.g., statins, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors), angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), and smoking cessation should be strongly encouraged for patients with CLI. This review examines these guideline-recommended therapies in terms of cardiovascular and limb-related risk reduction in patients with CLI.

Abstract
Bare-metal stents (BMSs) have been generally applied for the treatment of peripheral artery disease in patients with femoropopliteal disease. However, very long-term pathological findings after BMS implantation have not been elucidated to date. We experienced an autopsy case in which we performed a pathological evaluation 18 years after BMS implantation in the right superficial femoral artery. The BMS was totally occluded and filled with remarkable neointima formation. Neointima was mainly composed of a lot of rather atrophic smooth muscles and intercellular spaces containing dense collagenous fibers. Furthermore, regional fatty infiltration was also observed, but inflammatory cell infiltration, such as macrophages and lymphocytes, was not recognized obviously even around the struts. Judging from the pathological findings, the main mechanism of the very long-term in-stent restenosis in the patients with femoropopliteal disease was continuous proliferation of smooth muscle cells that led to the totally occlusive disease. This observation leads us to speculate that continuous elution of an anti-proliferating drug over a longer duration, at least beyond 1 year, would be effective to prevent chronic-phase restenosis. Further development of devices that can be used in the femoropopliteal artery is needed in light of this speculation. <Learning objective: Very long-term pathological findings after bare-metal stent (BMS) implantation in the femoropopliteal (FP) artery have not been elucidated to date. The BMS which was implanted in the FP artery 18 years before was totally occluded and filled with remarkable neointima formation due to smooth muscle cell (SMC) proliferation without any infiltration of inflammatory cells around the struts. The main mechanism of the very long-term in-stent restenosis of FP disease was continuous proliferation of SMC.>.

Abstract
Patients with lower extremity arterial disease are at increased risk for cardiovascular events. Antithrombotic therapy improves prognosis in these patients especially after peripheral revascularization. After endovascular revascularization duale anti-platelet therapy with Aspirin and Clopidogrel is used for up to 3 months in most cases, although there is only little evidence for this practice. Following peripheral bypass grafting most guidelines recommend single anti-platelet therapy. In some patients, anticoagulation with Vitamin K antagonists or dual anti-platelet therapy is indicated. But this practice is also based on small studies. The Vascular Outcomes Study of ASA Along With Rivaroxaban in Endovascular or Surgical Limb Revascularization for Peripheral Artery Disease (VOYAGER PAD) study is the largest randomized trial concerning antithrombotic therapy after peripheral revascularization. In total 6564 patients were included after successful surgical or endovascular lower-extremity revascularization. Rivaroxaban 2.5 mg twice daily plus Aspirin 100 mg reduced cardiac and peripheral events compared with Aspirin 100 mg alone with increased risk for relevant but not for critical bleeding complications. In addition to antithrombotic medication risk factor management and regular follow-up examinations are important improve long-term prognosis after peripheral revascularization.

Abstract
BACKGROUND Clopidogrel monotherapy is guideline-recommended in symptomatic peripheral artery disease (PAD). The advent of new antithrombotic strategies prompts an updated analysis of available evidence on antiplatelet therapy for PAD. METHODS We searched MEDLINE, Embase and CENTRAL through January 2019 for randomised controlled trials and observational studies comparing antiplatelet therapies as monotherapy, dual therapy, or combination with anticoagulants. Efficacy (major adverse cardiovascular events, acute or chronic limb ischaemia, vascular amputation, peripheral revascularisation) and safety (all-cause mortality and overall bleeding) outcomes were evaluated via Bayesian network meta-analyses. RESULTS We analysed 26 randomised controlled trials. Clopidogrel (hazard ratio, HR, 0.78; 95% credible interval [CrI] 0.65-0.93) and ticagrelor (HR 0.80; 95% CrI 0.65-0.98) significantly reduced major adverse cardiovascular events risk compared with aspirin. No significant difference was observed for dual antiplatelet therapy with clopidogrel and aspirin. Vorapaxar significantly reduced limb ischaemia and revascularisation compared with placebo, while dual antiplatelet therapy with clopidogrel and aspirin showed a trend for reduced risk of amputation compared with aspirin (risk ratio 0.68; 95% CrI 0.43-1.04). For all-cause mortality, picotamide, vorapaxar, dipyridamole with aspirin, and ticlopidine showed a significantly lower risk of all-cause mortality vs aspirin. Clopidogrel and ticagrelor showed similar overall bleeding risk vs aspirin, while dual antiplatelet therapy with clopidogrel and aspirin significantly increased bleeding risk. CONCLUSION This updated network meta-analysis confirms that clopidogrel significantly decreases the risk of major adverse cardiovascular events compared with aspirin, without increasing bleeding risk. Clopidogrel should remain a mainstay of PAD treatment, at least in patients at higher bleeding risk.

Abstract
AIMS To conduct a prospective randomized study to evaluate cilostazol, a phosphodiesterase 3 inhibitor, and compare it with aspirin for the prevention of the progression of atherosclerosis in patients with type 2 diabetes (T2D). MATERIALS AND METHODS Fifty patients with T2D and carotid atherosclerotic plaques were randomly assigned to either a 200 mg/d cilostazol (CTZ) group or a 100 mg/d aspirin (ASA) group for 6 months. The primary endpoint was change in plaque volume measured by carotid three-dimensional ultrasonography. The secondary endpoints were changes in carotid intima-media thickness (IMT) and endothelial function, assessed by laser Doppler. RESULTS Twenty-four patients in the CTZ group and 23 in the ASA group were included in the final analysis. The mean ± SD age of male (n = 20) and female (n = 16) patients was 62.2 and 59.1 years, respectively. The total plaque volume was slightly decreased in the CTZ group (from 183.8 ± 52.5 to 181.5 ± 54.0 mm3 ; P = .567), but significantly increased in the ASA group (from 112.9 ± 21.2 to 128.5 ± 23.3 mm3 ; P = .043). A significant regression in the maximum IMT was observed only in the CTZ group (right: from 2.19 ± 0.17 to 1.96 ± 0.12 mm; left: from 2.02 ± 0.20 to 1.72 ± 0.19 mm). The CTZ group exhibited an increase in HDL cholesterol and a decrease in triglycerides and liver enzymes. CONCLUSIONS Cilostazol treatment for 6 months significantly attenuated the progression of carotid plaque compared with aspirin in patients with T2D (NCT03248401).

Abstract
PURPOSE Evidence on the use of antithrombotic pharmacotherapy in patients undergoing revascularization of lower extremities for symptomatic peripheral arterial disease (PAD) is reviewed. SUMMARY Individuals with PAD can experience leg pain, intermittent claudication, critical limb ischemia, and acute limb ischemia. In such patients, revascularization may be indicated to improve the quality of life and to prevent amputations. Antithrombotic therapy is often intensified in the postrevascularization period to prevent restenosis of the index artery and to counteract the prothrombotic state induced by the intervention. Therapeutic modalities include dual antiplatelet therapy (DAPT), anticoagulation, a combination of antiplatelet and anticoagulation therapy, and addition of cilostazol to single antiplatelet therapy. Subgroup analyses of data from randomized clinical trials provided low-quality evidence for the use of DAPT in patients with a below-knee prosthetic bypass graft and anticoagulation for those with a venous bypass graft. Cilostazol, when added to aspirin therapy, has been shown to prevent index vessel reocclusion after an endovascular intervention in patients at low risk for thrombosis in several small randomized trials. CONCLUSION There is a considerable paucity of high-quality evidence on the optimal antithrombotic regimen for patients undergoing lower extremity revascularization, with no particular therapy shown to consistently improve patient outcomes. The decision to initiate intensified antithrombotic therapy should include a close examination of its risk-benefit profile. The demonstrated benefit of such treatment is restricted to the prevention of index artery reocclusion, while an increased risk of bleeding may lead to significant morbidity and mortality.

Abstract
This article presents a review of the literature on studying Cilostazol, a type 3 phosphodiesterase inhibitor, also providing the Russian and foreign statistics on the prevalence of peripheral artery disease. It is underlined that the majority of patients with peripheral artery disease have atherosclerotic lesions in the coronary and cerebral vascular basins. Cilostazol deservedly occupies the first lines in the sections of pharmacotherapy for intermittent claudication in international and Russian consensus documents on peripheral artery disease. The drug has an extensive evidence base for the following pharmacological effects: vasodilating, antiplatelet, endothelial protective, and vasculogenic. Clinical efficacy of Cilostazol was confirmed in 15 randomized clinical trials (3 718 patients with intermittent claudication) studying the use of Cilostazol taken twice daily at doses of 50 mg, 100 mg, and 150 mg as compared with placebo or versus pentoxifylline given in a dose of 400 mg three times daily, with a demonstrable increase in the pain-free walking distance and the maximal walking distance on the background of taking Cilostazol. The drug significantly improves the outcomes of endovascular interventions on arteries of lower extremities, decreasing the incidence of restenosis, prolonging limb survival, and reducing the frequency of major amputations. Many studies addressing the use of Cilostazol in patients with coronary and cerebral atherosclerosis have investigated the effect of the drug as a component of dual antiplatelet therapy (aspirin + Cilostazol) and triple antiplatelet therapy (aspirin + clopidogrel + Cilostazol) after endovascular interventions. The addition of Cilostazol to treatment resulted in a significant decrease in the occurrence of re-stenosis, with no increase in the incidence of haemorrhage. Cilostazol may be recommended for patients with multifocal atherosclerosis and resistance to aspirin and clopidogrel. Also presented in the article are the results of a Russian clinical trial studying comparative efficacy of Cilostazol and pentoxifylline in patients with intermittent claudication.

Abstract
Chronic deep venous disease (CVD) affects millions of Americans and can result in significant morbidity, such as debilitating lower extremity oedema, venous claudication, and in severe cases, venous ulcers. CVD can be caused by thrombotic and non-thrombotic disease processes, such as deep venous thrombosis and iliac compression syndrome. Recently, endovascular intervention with percutaneous transluminal angioplasty and venous stent placement has become the mainstay therapy for these patients, with several studies demonstrating its safety and efficacy. However, anticoagulation management following venous stent placement is largely unstudied, and there are no large randomised controlled trials or official guidelines establishing an optimal regimen. Most published studies are plagued with data heterogeneity and incomplete reporting. This is further complicated by rapidly evolving improvements in technique and dedicated devices in endovenous intervention. In this article, the authors discuss the current literature to date and offer an approach to anticoagulation and antiplatelet management following venous stent placement in CVD.

Abstract
BACKGROUND Current clinical guidelines recommend the use of cilostazol in the treatment of patients with infrainguinal peripheral artery disease (PAD) who experience intermittent claudication. However, the role of cilostazol therapy in patients with advanced PAD and critical limb ischemia (CLI) remains unclear. To conduct a meta-analysis of randomized controlled trials and cohort studies that evaluated the effect of cilostazol vs standard antiplatelet therapy on limb-related and arterial patency-related outcomes. We also reviewed literature pertinent to the effect of cilostazol on wound healing in patients with advanced PAD. METHODS We performed a MEDLINE, EMBASE, COCHRANE (CENTRAL), SCOPUS, and US Clinical Trials database search for all trials and studies since 1999 that compared cilostazol with standard antiplatelet therapy in the setting of infrainguinal PAD revascularization procedures (endovascular or open). Aggregate data was collected from four randomized control trials and six retrospective cohort studies. The end point incidence ratios and treatment effects were generated from each study and reported as hazard ratios (HR) using a random-effect model. We also reviewed 10 studies that evaluated the effect of cilostazol on wound healing in patients with advanced PAD. RESULTS From more than 25,000 total patients, 3136 patients met our inclusion criteria. All patients had at least lifestyle-impacting intermittent claudication, and more than 50% met the definition of CLI (Rutherford class ≥4). Patient age range was 53 to 83 years, and the majority were male (66%). The mean follow-up time averaged 2 years across all studies. Meta-analysis revealed that cilostazol treatment favored amputation-free survival (hazard ratio [HR], 0.79; 95% confidence interval [CI], 0.69-0.91), limb salvage rate (HR, 0.42; 95% CI, 0.27-0.66), decreased repeat revascularization (risk ratio [RR], 0.44; 95% CI, 0.37-0.52), and decreased restenosis (RR, 0.68; 95% CI, 0.61-0.76). Cilostazol treatment also increased freedom from target lesion revascularization (RR, 1.35; 95% CI, 1.21-1.53) with no difference in all-cause mortality. Effective wound healing was found to be an inconsistent outcome measure in patients receiving cilostazol therapy. CONCLUSIONS We observed that cilostazol therapy has a beneficial impact on all limb-related and arterial patency-related outcomes, but no effect on all-cause mortality in patients with advanced PAD and CLI undergoing revascularization procedures. Additional studies are needed to evaluate the effect of cilostazol therapy on wound healing in patients with advanced PAD.

Abstract
OBJECTIVE In-stent stenosis is a frequent complication of superficial femoral artery (SFA) endovascular intervention and can lead to stent occlusion or symptom recurrence. Arterial duplex stent imaging (ADSI) can be used in the surveillance for recurrent stenosis; however, its uniform application is controversial. In this study, we aimed to determine, in patients undergoing SFA stent implantation, whether surveillance with ADSI yielded a better outcome than in those with only ankle-brachial index (ABI) follow-up. METHODS We performed a retrospective analysis of all patients undergoing SFA stent implantation for occlusive disease at a tertiary care referral center between 2009 and 2016. The patients were divided into those with ADSI and those with ABI follow-up only. Life-table analysis comparing stent patency, major adverse limb events (MALEs), limb salvage, and mortality between groups was performed. RESULTS There were 248 patients with SFA stent implantation included, 160 in the ADSI group and 88 in the ABI group. Groups were homogeneous in clinical indications of claudication and critical limb-threatening ischemia (for ADSI, 39% and 61%; for ABI, 38% and 62%; P = .982) and TransAtlantic Inter-Society Consensus class A, B, C, and D lesions (for ADSI, 17%, 45%, 16%, and 22%; for ABI, 21%, 43%, 16%, and 20%; P = .874). Primary patency was similar between groups at 12, 36, and 56 months (ADSI, 65%, 43%, and 32%; ABI, 69%, 34%, and 34%; P = .770), whereas ADSI patients showed an improved assisted primary patency (84%, 68%, and 54%) vs ABI patients (76%, 38%, and 38%; P = .008) and secondary patency. There was greater freedom from MALEs in the ADSI group (91%, 76%, and 64%) vs the ABI group (79%, 46%, and 46%; P < .001) at 12, 36, and 56 months of follow-up. ADSI patients were more likely to undergo an endovascular procedure as their initial post-SFA stent implantation intervention (P = .001), whereas ABI patients were more likely to undergo an amputation (P < .001). CONCLUSIONS In SFA stent implantation, patients with ADSI follow-up demonstrate an advantage in assisted primary patency and secondary patency and are more likely to undergo an endovascular reintervention. These factors are likely to have effected a decrease in MALEs, indicating the benefit of a more universal adoption of post-SFA stent implantation follow-up ADSI.

Abstract
Endovascular intervention devices for femoral-popliteal arterial disease have evolved in the last decade to more effectively treat patients with symptoms of claudication, improve tissue healing, and prevent amputation in patients with critical limb ischemia. Drug-eluting stents and drug-coated balloon therapies have demonstrated significant improvements in short- and mid-term patency and decreases in future target vessel interventions over uncoated balloon angioplasty. Adjunctive lesion preparation options including atherectomy devices are available to treat more complex and calcified lesions, but comparative data are still required.

Abstract
Purpose: To identify intravascular ultrasound (IVUS) findings that predict midterm stent patency in femoropopliteal (FP) lesions. Materials and Methods: A retrospective analysis was undertaken of 335 de novo FP lesions in 274 consecutive patients (mean age 72.4±8.2 years; 210 men) who had IVUS assessment before and after successful stent implantation. The mean lesion length was 13.2±9.8 cm. The primary outcome was primary patency at 24 months, defined as freedom from major adverse limb event (MALE) and in-stent restenosis (ISR). MALE was defined as major amputation or any target lesion revascularization (TLR). ISR was defined by a peak systolic velocity ratio >2.4 by duplex ultrasonography. Logistic regression analyses were performed to identify independent predictors of stent patency at 24 months; the results are presented as the odds ratio (OR) and 95% confidence interval (CI). Receiver operator characteristic (ROC) curve analysis was performed to determine the optimal threshold for prediction of stent patency at 24 months. Results: Over the 24-month follow-up, 18 (7%) patients died and 43 (15%) of 286 lesions were responsible for MALE (42 TLRs and 1 major amputation). Primary patency was estimated at 82.5% (95% CI 78.1% to 86.9%) at 12 months and 73.2% (95% CI 67.9% to 78.5%) at 24 months. Multivariable analysis revealed that longer lesion length (OR 0.89, 95% CI 0.82 to 0.97, p<0.01) was an independent predictor of declining patency, while cilostazol use (OR 3.45, 95% CI 1.10 to 10.78, p=0.03) and increasing distal reference external elastic membrane (EEM) area (OR 1.18, 95% CI 1.02 to 1.37, p=0.03) were associated with midterm stent patency. ROC curve analysis identified a distal reference EEM area of 29.0 mm2 as the optimal cut-point for prediction of 24-month stent patency (area under the ROC curve 0.764). Kaplan-Meier estimates of 24-month primary patency were 83.7% (95% CI 78.3% to 89.2%) in lesions with a distal EEM area >29.0 mm2 vs 53.1% (95% CI 42.9% to 63.3%) in those with a distal EEM area ≤29.0 mm2 (p<0.001). Conclusion: In FP lesions with a larger distal vessel area estimated with IVUS, stent implantation can be considered as a reasonable treatment option, with the likelihood of acceptable midterm results.

Abstract
Abstract
Background
The literature on antiplatelet therapy for peripheral artery disease has historically been summarized inconsistently, leading to conflict between international guidelines. An umbrella review and meta-analysis was performed to summarize the literature, allow assessment of competing safety risks and clinical benefits, and identify weak areas for future research.
Methods
MEDLINE, Embase, DARE, PROSPERO and Cochrane databases were searched from inception until January 2019. All meta-analyses of antiplatelet therapy in peripheral artery disease were included. Quality was assessed using AMSTAR scores, and GRADE analysis was used to quantify the strength of evidence. Data were pooled using random-effects models.
Results
Twenty-eight meta-analyses were included. Thirty-three clinical outcomes and 41 antiplatelet comparisons in 72 181 patients were analysed. High-quality evidence showed that antiplatelet monotherapy reduced non-fatal strokes (3 (95 per cent c.i. 0 to 6) fewer per 1000 patients), In symptomatic patients, it reduced cardiovascular deaths (8 (0 to 16) fewer per 1000 patients), but increased the risk of major bleeding (7 (3 to 14) more events per 1000). In asymptomatic patients, monotherapy reduced non-fatal strokes (5 (0 to 8) fewer per 1000), but had no other clinical benefit. Dual antiplatelet therapy caused more major bleeding after intervention than monotherapy (37 (8 to 102) more events per 1000), with very low-quality evidence of improved endovascular patency (risk ratio 4·00, 95 per cent c.i. 0·91 to 17·68).
Conclusion
Antiplatelet monotherapy has minimal clinical benefit for asymptomatic peripheral artery disease, and limited benefit for symptomatic disease, with a clear risk of major bleeding. There is a lack of evidence to guide antiplatelet prescribing after peripheral endovascular intervention.

Abstract
Endovascular intervention is often used to treat critical limb ischemia (CLI). Post-intervention treatment with antiplatelet and/or anticoagulant therapy has reduced morbidity and mortality due to cardiovascular complications. The purpose of this review is to shed light on the various pharmacologic treatment protocols for treating CLI following endovascular procedures. We reviewed the literature comparing outcomes after antithrombotic treatment for patients with CLI. We characterized antithrombotic therapies into three categories: (1) mono-antiplatelet therapy (MAPT) vs. dual antiplatelet therapy (DAPT), (2) MAPT vs. antiplatelet (AP) + anticoagulant (AC) therapy, and (3) AC vs. AP + AC therapy. Relevant results and statistics were extracted to determine differences in the rates of the following outcomes: (1) re-stenosis, (2) occlusion, (3) target limb revascularization (TLR), (4) major amputation, (5) major adverse cardiac events, (6) all-cause death, and (7) bleeding. Studies suggest that DAPT reduces post-surgical restenosis, TLR, and amputation for diabetic patients, without increasing major bleeding incidences, compared to MAPT. Also, AP + AC therapy provides overall superior efficacy, with no difference in bleeding incidences, compared to antiplatelet alone. Additionally, the effects were significant for restenosis, limb salvage, survival rates, and cumulative rate of above ankle amputation or death. These results suggest that treatment with DAPT and AP + AC might provide better outcomes than MAPT following the endovascular intervention for CLI, and that the ideal treatment may be related to the condition of the individual patient. However, the studies were few and heterogenous with small patient populations. Therefore, further large controlled studies are warranted to confirm these outcomes.

Abstract
BACKGROUND New-generation bare-metal nitinol (BNS) and drug-eluting stents have improved long-term outcomes in patients undergoing endovascular therapy for femoropopliteal lesions. Furthermore, cilostazol reduces in-stent restenosis (ISR) after first-generation BNS implantation for femoropopliteal lesions. METHODS AND RESULTS We studied 255 patients with femoropopliteal lesions treated at 25 cardiovascular centers. Patients were randomly assigned to the BNS group (Misago stent implantation without cilostazol), BNS with cilostazol group (Misago stent implantation with cilostazol), or drug-eluting stents group (Zilver PTX stent implantation without cilostazol). Primary end point was 1-year restenosis noted using duplex ultrasound (peak systolic velocity ratio, >2.0). Secondary end point was major adverse limb events (limb-related death, target lesion revascularization, major amputation, and major bleeding). During the 1-year follow-up, 12 patients (4.7%) died and 237 (92.9%) had relevant ultrasound findings. The 1-year ISR rate did not differ significantly among the BNS, BNS with cilostazol, and drug-eluting stents groups (28.4% versus 12.2% versus 21.0%; P=0.052). Although the 1-year ISR rate was significantly lower in the BNS with cilostazol group than in the BNS group, it was similar to that in the drug-eluting stents group ( P=0.16). Major adverse limb event was significantly higher in the BNS group (16.9% versus 6.5% versus 6.3%; P=0.034); however, target lesion revascularization and major bleeding were similar (9.7% versus 5.1% versus 3.6%; P=0.25, 4.8% versus 1.2% versus 2.4%; P=0.37, respectively). CONCLUSIONS Misago stent implantation with cilostazol showed a comparable 1-year ISR rate with Zilver PTX. Cilostazol reduced the 1-year ISR rate after endovascular therapy when used with new-generation BNS. CLINICAL TRIAL REGISTRATION URL: http://www.umin.ac.jp/ctr/ . Unique identifier: UMIN 000010071.

Abstract
Purpose: To evaluate the effect of vessel calcification on in-stent restenosis (ISR) after drug-coated stent (DCS) placement in the femoropopliteal segment. Materials and Methods: A retrospective multicenter study was undertaken involving 220 consecutive symptomatic patients (mean age 73.1±8.3 years; 175 men) with femoropopliteal lesions in 230 limbs treated with the Zilver PTX DCS and having duplex surveillance after the endovascular procedures. Mean lesion length was 16.4±9.8 cm (range 2–40); there were 104 (45.2%) total occlusions and 68 (29.6%) in-stent restenoses (ISR). Twenty (8.7%) vessels had no runoff. The majority of lesions (148, 64.3%) were calcified according to the peripheral arterial calcium scoring system (PACSS). Primary patency was evaluated by duplex. Lesions were classified as either PACSS 0–2 (none or unilateral wall calcification) or PACSS 3 and 4 (bilateral wall calcification). Multivariate analysis was performed to identify variables associated with ISR; the results are given as the hazard ratio (HR) and 95% confidence interval (CI). Results: The 1-, 2-, and 5-year primary patency and freedom from clinically-driven target lesion revascularization estimates were 75.9%, 63.6%, and 45.0%, and 84.7%, 73.7%, and 54.2%, respectively. Major amputations were performed on 4 limbs during follow-up. In multivariate analysis, vessel calcification (adjusted HR 1.718, 95% CI 1.035 to 2.851, p=0.036) was significantly correlated with the occurrence of ISR, along with lesion length (adjusted HR 1.041, 95% CI 1.013 to 1.070, p=0.003), and cilostazol administration (adjusted HR 0.476, 95% CI 0.259 to 0.876, p=0.017). Conclusion: This study suggested that bilateral vessel wall calcification was an independent risk factor for ISR in complex femoropopliteal lesions after Zilver PTX DCS placement, along with lesion length; cilostazol administration had a protective effect.

Abstract
GUIDELINE SUMMARY Chronic limb-threatening ischemia (CLTI) is associated with mortality, amputation, and impaired quality of life. These Global Vascular Guidelines (GVG) are focused on definition, evaluation, and management of CLTI with the goals of improving evidence-based care and highlighting critical research needs. The term CLTI is preferred over critical limb ischemia, as the latter implies threshold values of impaired perfusion rather than a continuum. CLTI is a clinical syndrome defined by the presence of peripheral artery disease (PAD) in combination with rest pain, gangrene, or a lower limb ulceration >2 weeks duration. Venous, traumatic, embolic, and nonatherosclerotic etiologies are excluded. All patients with suspected CLTI should be referred urgently to a vascular specialist.

Abstract
Chronic limb-threatening ischemia (CLTI) is associated with mortality, amputation, and impaired quality of life. These Global Vascular Guidelines (GVG) are focused on definition, evaluation, and management of CLTI with the goals of improving evidence-based care and highlighting critical research needs. The term CLTI is preferred over critical limb ischemia, as the latter implies threshold values of impaired perfusion rather than a continuum. CLTI is a clinical syndrome defined by the presence of peripheral artery disease (PAD) in combination with rest pain, gangrene, or a lower limb ulceration >2 weeks duration. Venous, traumatic, embolic, and nonatherosclerotic etiologies are excluded. All patients with suspected CLTI should be referred urgently to a vascular specialist. Accurately staging the severity of limb threat is fundamental, and the Society for Vascular Surgery Threatened Limb Classification system, based on grading of Wounds, Ischemia, and foot Infection (WIfI) is endorsed. Objective hemodynamic testing, including toe pressures as the preferred measure, is required to assess CLTI. Evidence-based revascularization (EBR) hinges on three independent axes: Patient risk, Limb severity, and ANatomic complexity (PLAN). Average-risk and high-risk patients are defined by estimated procedural and 2-year all-cause mortality. The GVG proposes a new Global Anatomic Staging System (GLASS), which involves defining a preferred target artery path (TAP) and then estimating limb-based patency (LBP), resulting in three stages of complexity for intervention. The optimal revascularization strategy is also influenced by the availability of autogenous vein for open bypass surgery. Recommendations for EBR are based on best available data, pending level 1 evidence from ongoing trials. Vein bypass may be preferred for average-risk patients with advanced limb threat and high complexity disease, while those with less complex anatomy, intermediate severity limb threat, or high patient risk may be favored for endovascular intervention. All patients with CLTI should be afforded best medical therapy including the use of antithrombotic, lipid-lowering, antihypertensive, and glycemic control agents, as well as counseling on smoking cessation, diet, exercise, and preventive foot care. Following EBR, long-term limb surveillance is advised. The effectiveness of nonrevascularization therapies (eg, spinal stimulation, pneumatic compression, prostanoids, and hyperbaric oxygen) has not been established. Regenerative medicine approaches (eg, cell, gene therapies) for CLTI should be restricted to rigorously conducted randomizsed clinical trials. The GVG promotes standardization of study designs and end points for clinical trials in CLTI. The importance of multidisciplinary teams and centers of excellence for amputation prevention is stressed as a key health system initiative.

Antithrombotic therapy after femoropopliteal artery stenting: 12-month results from Japan Postmarketing Surveillance. HEART ASIA 2019; 11:e011114.

Abstract
Objective To investigate the effects of antithrombotic therapy on target lesion revascularisation (TLR) and major adverse cardiovascular and cerebrovascular events (MACCEs) at 12 months after femoropopliteal intervention with second-generation bare metal nitinol stents. Methods A total of 277 lesions in 258 limbs of 248 patients with de novo atherosclerosis in the above-the-knee femoropopliteal segment were analysed from the Japan multicentre postmarketing surveillance. Results At discharge, dual antiplatelet therapy (DAPT) was prescribed in 68.5% and cilostazol in 30.2% of patients. At 12 months of follow-up, prescriptions of DAPT significantly (p=0.0001) decreased to 51.2% and prescription of cilostazol remained unchanged (p=0.592) at 28.0%. Prescription of warfarin also remained unchanged (14.5% at discharge, 13.3% at 12 months, p=0.70). At 12 months, freedoms from TLR and MACCE were 89.4% and 89.7%, respectively. In a multivariate Cox proportional hazards model, neither DAPT nor cilostazol at discharge was associated with both TLR and MACCE at 12 months. However, warfarin at discharge was only independently associated with TLR at 12 months. Kaplan-Meier estimates demonstrated that warfarin at discharge yielded a significantly (p=0.013) lower freedom from TLR at 12 months than no warfarin at discharge. Freedom from TLR at 12 months by the Kaplan-Meier estimates was 77.8% (95% CI 59.0% to 88.8%) in patients with warfarin at discharge and 91.2% (95% CI 86.3% to 94.3%) in those without warfarin at discharge. Conclusions Clinical benefits of DAPT or cilostazol might be small in terms of TLR and MACCE at 12 months. Anticoagulation with warfarin at discharge might increase TLR at 12 months.

Abstract
The role of cilostazol after endovascular therapy (EVT) of peripheral artery disease (PAD) remains unclear. We conducted a meta-analysis for all studies reporting the outcomes of cilostazol after EVT of PAD from January 2000 through November 2018 with the outcomes of interest including primary patency, major adverse limb events (MALE), target lesion revascularization (TLR), and major amputation. We included eight studies (three randomized controlled trials (RCTs) and five observational studies) with a total of 3846 patients (4713 lesions). During a mean follow-up duration of 12.5 ± 5 months, the use of cilostazol was associated with higher primary patency (OR 2.28, 95% CI (1.77, 2.94), p < 0.001, I2 = 24%), lower risk of TLR (OR 0.37, 95% CI (0.26, 0.52), p < 0.001, I2 = 0%), and lower risk of major amputation (OR 0.15, 95% CI (0.04, 0.62), p = 0.008, I2 = 0%). The use of cilostazol in RCTs was associated with significantly higher odds of primary patency compared with observational studies (OR 3.37 vs 2.28, p-interaction = 0.03). After further subgroup analysis, cilostazol remained associated with higher primary patency regardless of the use of anticoagulants (warfarin) (p-interaction = 0.49). We conclude that the use of cilostazol after EVT of femoropopliteal and iliac lesions is associated with improved primary patency and lower risk of major amputation and TLR. The favorable impact of cilostazol is independent of the use of warfarin. PROSPERO identifier: CRD42018092715.

Abstract
BACKGROUND AND OBJECTIVE The results of studies on cilostazol-based triple antiplatelet therapy (TAT) after drug-eluting stent (DES) implantation were inconsistent. To assess the effects of TAT compared with dual antiplatelet therapy (DAT) after DES/second-generation DES implantation, we performed a meta-analysis of randomized controlled trials (RCTs). METHODS All relevant studies evaluated were identified by searching the PubMed, EMBASE, Cochrane Library, and ISI Web of Science databases without time and language limitation. Subgroup analyses were performed to evaluate the efficacy and safety of TAT after second-generation DES implantation. RESULTS Eleven RCTs involving a total of 4684 patients were included. The meta-analysis showed TAT was associated with significant beneficial effects on angiographic findings of in-stent restenosis [risk ratio (RR) 0.645, 95% confidence interval (CI) 0.470-0.885; P = 0.007], in-segment restenosis (RR 0.606, 95% CI 0.450-0.817; P = 0.001), in-stent late loss (RR - 0.095, 95% CI - 0.136 to - 0.054; P < 0.0001), in-segment late loss (RR - 0.100, 95% CI - 0.139 to - 0.061; P < 0.0001), target lesion revascularization (TLR) (RR 0.570, 95% CI 0.430-0.755; P < 0.0001), and target vessel revascularization (TVR) (RR 0.523, 95% CI 0.380-0.719; P < 0.0001). No significant difference was found in outcomes of all-cause death, cardiac death, definite/probable stent thrombosis (ST), non-fatal myocardial infarction (MI), overall bleeding, and major bleeding between the two groups, as well as some minor adverse effects including palpitations, thrombocytopenia, neutropenia, and hepatic dysfunction. However, the incidence rate of rash, gastrointestinal disorders, and headache was significantly higher in TAT. The second-generation DES subgroup showed similar results, except for the indicators of all-cause death (RR 2.161, 95% CI 1.007-4.635; P = 0.048) and hepatic dysfunction (RR 0.176, 95% CI 0.031-0.995; P = 0.049). CONCLUSIONS Compared with DAT, cilostazol-based TAT can significantly improve the angiographic findings of in-stent and in-segment late loss, in-stent and in-segment restenosis, TLR, and TVR after DES/second-generation DES implantation. However, no benefits were observed in outcomes of all-cause death, cardiac death, ST, and MI.

Abstract
Aim: Although the Innova™ self-expanding nitinol stent (Boston Scientific, Marlborough, MA) exhibits acceptable performance in long-term safety and efficacy when used for the treatment of femoropopliteal (FP) lesions, clinical outcomes following its implantation have not been systematically studied in real-world settings. We investigated the one-year clinical outcomes after implantation of Innova™ self-expanding nitinol stents for the treatment of FP lesions in real-world settings. Methods: In this multicenter study, 481 lesions in 453 consecutive patients with peripheral artery disease (PAD) (74 ± 9 years; male, 70%; diabetes mellitus, 61%; dialysis, 27%; critical limb ischemia, 37%) who underwent endovascular therapy with the implantation of Innova™ self-expanding nitinol stents for FP lesions were analyzed from February 2016 to April 2017. The primary endpoint was one-year restenosis, whereas the secondary endpoints included one-year major adverse limb events and predictors for one-year restenosis. Results: The mean lesion length was 18 ± 10 cm. One-year restenosis and major adverse limb event rates were 36% and 18%, respectively. Multivariate analysis revealed that the presence of diabetes mellitus (odds ratio [OR]: 1.83; 95% confidence interval [CI]: 1.07–3.13), distal reference vessel diameter (OR: 1.86; 95% CI: 1.09–3.16), spot stenting (OR: 2.27; 95% CI: 1.27–4.06), and lack of one-year cilostazol treatment (OR: 0.58; 95% CI: 0.33–1.00) were independent risk factors for one-year restenosis. Conclusion: The current study demonstrated one-year clinical outcomes after Innova™ self-expanding nitinol stent placement for the treatment of FP lesions, including challenging cases in real-world settings.

Abstract
BACKGROUND The prevalence of diabetes has increased significantly in well-developed countries during the last decade and it continues to grow. Diabetes increases the risk of restenosis in patients treated percutaneously for peripheral artery disease. The present study sought to compare outcomes of atherectomy treatment in diabetic (DM) vs. non-diabetic (nDM) patients suffering from peripheral artery disease. METHOD Between 2008 and 2012, 204 revascularization atherectomy procedures were performed on arteries of the lower extremities. The endpoints included target lesion revascularization (TLR), amputation and death. The type of atherectomy (excisional-soft plaque, orbital-calcified plaque, with active aspiration - with a thrombus) was left to operator discretion. RESULTS This study contains 132 DM (66% male, age 68 ± 11.2 years) and 72 nDM (63% male, age 75 ± 11.3 years) subjects. DM were younger but had a higher prevalence of coronary artery disease (DM: 91% vs. nDM: 62%, p < 0.0001) and end-stage renal disease (DM: 22% vs. nDM: 2.5%, p < 0.0001). There were no differences in critical limb ischemia between the groups (DM: 21% vs. nDM: 12%, p = = 0.13). Mean time of follow-up was 384 and 411 days in DM and nDM, respectively (p = 0.43). There were no significant differences in TLR (DM: 15.2% vs. nDM: 22.2%, p = 0.249), amputations (DM: 3.0% vs. nDM: 1.5%, p = NS) or death rates (DM: 2.2% vs. nDM: 2.7%, p = NS). Kaplan-Mayer analysis showed no significant differences between the groups in the time to TLR, amputation or death. CONCLUSIONS Plaque modification with adjusted atherectomy appears to have similar outcomes in diabetic as well as in non-diabetic patients. Nonetheless, a randomized study would be warranted to confirm the findings of the current study.

Abstract
Atherosclerotic cardiovascular (CV) disease represents one of leading cause of mortality and morbidity in Western countries. An increased risk of CV events was identified in patients with peripheral arterial diseases (PADs), which include all arterial diseases, other than coronary arteries and the aorta. In particular, lower extremity artery disease (LEAD) and/or carotid artery disease present growing incidence in general population and a consequent increase in mortality and morbidity. Medical treatment, including antiplatelet therapy, is a cornerstone in management of these patients, even when they are treated with endovascular or surgical procedures. Despite their clinical relevance, data on optimal antiplatelet treatment in this clinical setting are lacking and often derived from clinical trials on coronary artery disease and by subgroups analysis. The purpose of this review is to examine the available data from registries, randomized trials and meta-analysis on antiplatelet treatment in patients with LEAD and carotid stenosis with the aim to provide evidence to support clinical decision making.

Abstract
BACKGROUND Currently, there exist limited data on patient outcomes following the use of drug-coated balloons (DCBs) to treat complex femoropopliteal arterial occlusive lesions. The aim of the this study is to investigate the outcomes of patient treated with DCBs and to identify the predictors of restenosis. METHODS We retrospectively investigated medical records from 120 patients (137 limbs) treated with DCBs for femoropopliteal lesions at a single center between 2013 and 2016. Primary patency, target lesion revascularization (TLR), and risk factors of restenosis were analyzed. RESULTS There were 80 de novo and 57 in-stent restenosis lesions. Mean lesion length was 22.2 ± 11.6 cm. The clinical primary patency was 85.2% at 1 year and 65.3% after 2 years. The TLR-free survival rate was 93.0% at 1 year and 87.1% after 2 years. Critical limb ischemia (CLI; hazard ratio [HR] 5.80, 95% confidence interval [CI] 1.26-26.68, P = 0.024) and hypercholesterolemia (HR 4.66, 95% CI 1.30-16.76, P = 0.018) were identified as independent predictors of restenosis. In addition, nonuse of cilostazol and popliteal artery involvement showed trends toward an increased risk of restenosis. CONCLUSIONS Treatment with DCBs showed excellent primary patency and TLR-free survival at 1 year after the procedure. However, the primary patency continuously deteriorated beyond 1 year, suggesting a late catch-up phenomenon. The risk of restenosis after treatment with DCBs was significantly associated with CLI and hypercholesterolemia.
