ZILVERPASS Study: ZILVER PTX Stent versus Prosthetic Above-the-Knee Bypass Surgery in Femoropopliteal Lesions, 5-year Results.
PURPOSE
To report the 60-month safety and effectiveness results of a multicenter, prospective, randomized controlled trial comparing the ZILVER PTX paclitaxel-eluting stent to prosthetic above-the-knee bypass for the treatment of symptomatic TransAtlantic Inter-Society Consensus (TASC) C and D femoropopliteal lesions.
MATERIALS AND METHODS
Patients were enrolled between October 2013 and July 2017. One of the secondary outcomes was primary patency at 60 months, defined as no evidence of binary restenosis or occlusion within the target lesion or bypass graft based on a duplex ultrasound peak systolic velocity ratio < 2.4 and no clinically-driven target lesion revascularization (TLR) in endovascular cases or reintervention to restore flow in the bypass at 60 months. Survival rates after 5 years were also analyzed.
RESULTS
220 patients (mean age 68.6 ± 10.5 years; 159 men) were included and randomized to ZILVER PTX (n = 113, 51.40%) or BYPASS group (n = 107, 48.60%). The 60-month primary patency rate was 49.3% for the ZILVER PTX group versus 40.7% for the bypass group (p = 0.6915). Freedom from TLR was 63.8% for the ZILVER PTX group versus 52.8% for the bypass group (p = 0.2637). At 5 years, no significant difference in survival rate could be seen between the ZILVER PTX and the bypass group (69.1% vs. 71% respectively, p = 0.5503).
CONCLUSION
Even at 5Â years, non-inferior safety and effectiveness results of the ZILVER PTX could be seen. These findings confirmed that the use of ZILVER PTX stents can be considered as a valid alternative for bypass surgery when treating long and complex femoropopliteal lesions
Drug-coated balloon treatment of femoropopliteal lesions for patients with intermittent claudication and ischemic rest pain : 2-year results from the IN.PACT global study
Drug-Coated Balloon Treatment of Femoropopliteal Lesions for Patients With Intermittent Claudication and Ischemic Rest Pain: 2-Year Results From the IN.PACT Global Study
OBJECTIVES The IN.PACT Global Study is the largest prospective, multicenter, independently adjudicated trial to evaluate a paclitaxel drug-coated balloon in patients with lifestyle-limiting claudication and/or ischemic rest pain due to atherosclerotic disease of the femoropopliteal artery and includes complex lesions beyond what are typically included in randomized controlled trials. BACKGROUND Randomized controlled trials have demonstrated the safety and efficacy of drug-coated balloons for the treatment of Trans-Atlantic Inter-Society Consensus Document II A and B lesions, but there is a need for large-scale prospective studies to evaluate a broader range of lesions. METHODS The IN.PACT Global Study enrolled 1,535 subjects, and 1,406 (1,773 lesions) were included in the pre-defined clinical cohort analysis. Freedom from clinically driven target lesion revascularization was evaluated at 24 months. The safety composite endpoint was freedom from device- and procedure-related death through 30 days and freedom from target limb major amputation and clinically driven target vessel revascularization within 24 months. RESULTS Mean lesion length was 12.1 cm, 35.5% were total occlusions, and 18.0% had in-stent restenosis. Freedom from clinically driven target lesion revascularization at 24 months was 83.3%, the composite safety endpoint was met in 81.7%, the 2-year all-cause mortality rate was 7.0%, and the major target limb amputation rate was 0.7%. Increased lesion length and the presence of de novo in-stent restenosis or coronary artery disease were associated with increased risk for clinically driven target lesion revascularization by 24 months. CONCLUSIONS This real-world study of femoropopliteal artery disease treatment with drug-coated balloons confirmed positive findings reported from more strictly designed randomized controlled trials and showed that outcomes are durable in this population up to 2 years after treatment.

Which is currently the best strategy for treatment of SFA in-stent restenosis?
Stents have been created to prevent vessel recoil after percutaneous transluminal angioplasty (PTA). Despite the evolution in stent design, intimal hyperplasia and stent fractures and the resulting in-stent restenosis (ISR) still occur. Different strategies to treat ISR have been described with variable results in patency rates in the short and the long-term. PTA only in the treatment of ISR showed high procedural success, but the mid and long-term patency rates were very disappointing. Atherectomy devices have showed same insufficient results. If stent fracture is the cause of the ISR, the fracture has to be overstent. The best two options are covered stents and drug eluting stents (DES). Drug eluting devices like DES and drug eluting balloons (DEBs) showed promising results, with patency rates up to over 90% after one year. DEBs have the advantage of leaving nothing behind. Combined treatment of ISR with atherectomy and DEB has a similar good result. Endovascular brachytherapy showed high patency rates after one year but this technique is limited due to the time-consuming nature of the procedure, complex radiation safety measurements, and staffing requirements. Overall drug-eluting devices are emerging as the best treatment of SFA ISR with patency rates over 90% after 2 years

Outcomes After Drug-Coated Balloon Treatment of Femoropopliteal Lesions in Patients With Critical Limb Ischemia: A Post Hoc Analysis From the IN.PACT Global Study
Purpose: To report a post hoc analysis performed to evaluate 1-year safety and efficacy of the IN.PACT Admiral drug-coated balloon (DCB) for the treatment of femoropopliteal lesions in subjects with critical limb ischemia (CLI) enrolled in the IN.PACT Global study (ClinicalTrials.gov identifier NCT01609296). Materials and Methods: Of 1535 subjects enrolled in the study, 156 participants (mean age 71.8±10.4; 87 men) with CLI (Rutherford categories 4,5) were treated with DCB angioplasty in 194 femoropopliteal lesions. This cohort was compared to the 1246 subjects (mean age 68.2±10.0 years; 864 men) with intermittent claudication (IC) treated for 1573 lesions. The CLI cohort had longer lesions (13.9±10.6 vs 11.9±9.4 cm, p=0.009) and a higher calcification rate (76.8% vs 67.7%, p=0.011). Major adverse events [MAE; composite of all-cause mortality, clinically-driven target lesion revascularization (CD-TLR), major (above-ankle) target limb amputation, and thrombosis at the target lesion site], lesion and vessel revascularization rates, and EuroQol-5D were assessed through 1 year. The Kaplan-Meier method was used to estimate survival, CD-TLR, and amputation events; estimates are presented with the 95% confidence intervals (CI). Results: Estimates of 12-month freedom from major target limb amputation were 98.6% (95% CI 96.7% to 100.0%) in subjects with CLI and 99.9% (95% CI 99.8% to 100.0%) in subjects with IC (p=0.002). Freedom from CD-TLR through 12 months was 86.3% (95% CI 80.6% to 91.9%) in CLI subjects and 93.4% (95% CI 91.9% to 94.8%) in IC subjects (p<0.001). The MAE rate through 12 months was higher in CLI subjects (22.5% vs 10.7%, p<0.001), and CLI patients had poorer overall survival (93.0%, 95% CI 88.9% to 97.2%) than IC subjects (97.0%, 95% CI 96.0% to 97.9%, p=0.011). Health status significantly improved in all domains at 6 and 12 months in both groups. Conclusion: Treatment of femoropopliteal disease with DCB in CLI patients is safe through 12-month follow-up, with a low major amputation rate of 1.4%. The rates of MAE and CD-TLR were higher in CLI subjects and reinterventions were required sooner. Additional research is needed to evaluate long-term outcomes of DCB treatment for femoropopliteal lesions in CLI patients
