  • 文章类型: Journal Article
    背景:关于复杂股pop血管内血运重建的不同介入策略的比较数据有限。
    目的:在本研究中,作者旨在比较支架避免(SA)和支架优先(SP)策略,促进最佳的病变准备和药物洗脱技术的使用。
    方法:在预期的范围内,多中心,试点研究,120例有症状的股pop复杂病变(Rutherford分类2-4,平均病变长度187.7±78.3mm,79.2%的总闭塞)以1:1的方式随机分配给紫杉醇涂层球囊或聚合物涂层的血管内治疗,紫杉醇洗脱支架。在两个治疗组中,包括使用装置进行斑块修饰和/或去除,由操作者自行决定。
    结果:在SA组中,病变准备更频繁(71.7%SA[43/60]vs51.7%[31/60]SP;P=0.038),临时支架置入率高(48.3%[29/60])。在12个月的随访中,SA组为78.2%(43/55),SP组为78.6%(44/56)(P=1.0;相对危险度:0.995;95%CI:0.818-1.210).SA组为93.1%(54/58),SP组为94.9%(56/59)(P=0.717;相对危险度:0.981;95%CI:0.895-1.075),所有不良事件均归因于临床驱动的靶病变血运重建。
    结论:在使用药物洗脱装置之前促进病变准备的两种血管内策略均表明,在复杂的股pop手术中具有良好的疗效和安全性,并且在12个月内总闭塞的比例很高。持续的后续行动将显示随着时间的推移是否会出现不同的结果。(股浅动脉复杂病变的最佳血管内治疗策略[BEST-SFA];NCT03776799)。
    BACKGROUND: Limited comparative data exist on different interventional strategies for endovascular revascularization of complex femoropopliteal interventions.
    OBJECTIVE: In this study, the authors aimed to compare a stent-avoiding (SA) vs a stent-preferred (SP) strategy, promoting optimal lesion preparation and the use of drug-eluting technologies in both arms.
    METHODS: Within a prospective, multicenter, pilot study, 120 patients with symptomatic complex femoropopliteal lesions (Rutherford classification 2-4, mean lesion length 187.7 ± 78.3 mm, 79.2% total occlusions) were randomly assigned in a 1:1 fashion to endovascular treatment with either paclitaxel-coated balloons or polymer-coated, paclitaxel-eluting stents. Lesion preparation including the use of devices for plaque modification and/or removal was at the operators\' discretion in both treatment arms.
    RESULTS: In the SA group, lesion preparation was more frequently performed (71.7% SA [43/60] vs 51.7% [31/60] SP; P = 0.038) with a high provisional stenting rate (48.3% [29/60]). At the 12-month follow-up, primary patency was 78.2% (43/55) in the SA group and 78.6% (44/56) in the SP group (P = 1.0; relative risk: 0.995; 95% CI: 0.818-1.210). Freedom from major adverse events was determined in 93.1% (54/58) in the SA group and in 94.9% (56/59) in the SP group (P = 0.717; relative risk: 0.981; 95% CI: 0.895-1.075), with all adverse events attributable to clinically driven target lesion revascularization.
    CONCLUSIONS: Both endovascular strategies promoting lesion preparation before the use of drug-eluting devices suggest promising efficacy and safety results in complex femoropopliteal procedures with a high proportion of total occlusions through 12 months. Ongoing follow-up will show whether different results emerge over time. (Best Endovascular Strategy for Complex Lesions of the Superficial Femoral Artery [BEST-SFA]; NCT03776799).

  • 文章类型: Meta-Analysis
    背景:根据随机临床试验的荟萃分析,用于下肢血管内血运重建的紫杉醇涂层装置(PCDs)可能与晚期死亡风险增加相关。
    目的:本研究的目的是确定在现实环境中PCDs是否与全因死亡率相关。
    方法:检测是全国性的,详尽的回顾性队列研究使用来自法国国家医疗保健系统的医学管理数据,代表>99%的人口。主要选择标准是第一个感兴趣的程序:2011年10月1日至2019年12月31日期间进行的涉及≥1个球囊和/或支架的下肢外周动脉疾病的血管内血运重建。在2021年12月31日之前,对有或没有PCDs的患者的全因死亡率进行比较。
    结果:共分析了259,137例患者,20,083(7.7%)接受≥1PCD治疗。经过4.1年的中位数随访(Q1-Q3:2.3-6.4年),PCD组和对照组共观察到5,385例死亡/73,923人年(PY)(7.3/100PY)和109,844例死亡/1,060,513PY(10.4/100PY),分别。在对混杂因素进行调整后,在多变量Cox分析中,PCD治疗与较低的死亡风险相关(HR:0.86;95%CI:0.84-0.89;P<0.001)。使用基于最近邻或精确匹配的倾向评分匹配方法观察到类似的结果。
    结论:在基于大规模现实世界数据的全国性分析中,在接受下肢外周动脉疾病血管内血运重建术的患者中,PCDs暴露与较高的死亡风险无关.(检测项目;NCT05254106)。
    BACKGROUND: According to a meta-analysis of randomized clinical trials, paclitaxel-coated devices (PCDs) for lower limb endovascular revascularization may be associated with increased risk of late mortality.
    OBJECTIVE: The purpose of this study was to determine whether PCDs are associated with all-cause mortality in a real-world setting.
    METHODS: DETECT is a nationwide, exhaustive retrospective cohort study using medico-administrative data from the French National Healthcare System representing >99% of the population. The main selection criterion was the first procedure of interest: endovascular revascularization for lower limb peripheral artery disease involving ≥1 balloon and/or stent performed between October 1, 2011, and December 31, 2019. Patients with or without PCDs were compared for all-cause mortality until December 31, 2021.
    RESULTS: A total of 259,137 patients were analyzed, with 20,083 (7.7%) treated with ≥1 PCD. After a median follow-up of 4.1 years (Q1-Q3: 2.3-6.4 years), a total of 5,385 deaths/73,923 person-years (PY) (7.3/100 PY) and 109,844 deaths/1,060,513 PY (10.4/100 PY) were observed in the PCD and control groups, respectively. After adjustment for confounding factors, PCD treatment was associated with a lower risk of mortality in multivariable Cox analyses (HR: 0.86; 95% CI: 0.84-0.89; P < 0.001). Similar results were observed using propensity score matching approaches based on either nearest-neighbor or exact matching.
    CONCLUSIONS: In a nationwide analysis based on large-scale real-world data, exposure to PCDs was not associated with a higher risk of mortality in patients undergoing endovascular revascularization for lower limb peripheral artery disease. (The DETECT Project; NCT05254106).

    BACKGROUND: Paclitaxel-eluting devices (PED) reduce restenosis and target lesion revascularization (TLR) in femoropopliteal intervention. Recent data suggest a two-fold increased long-term mortality in patients treated with PED. The aim of our study is to evaluate if endovascular therapy (EVT) with PED increases mortality risk in patients with symptomatic lower limb peripheral artery disease (PAD) compared to non-eluting devices (NED).
    METHODS: The study is a retrospective, single-center registry on patients undergoing EVT for PAD from January 2009 to June 2018. Propensity score analysis on logistic regression model for independent predictors of long-term mortality was used to match PED and NED patients. Mortality was assessed at 2, 5 and 7 years in the entired matched population and in a sub-group of patients ≤75 years.
    RESULTS: During the study period, 1294 patients, 718 NED and 576 PED, met the inclusion/exclusion criteria and entered in the study. Propensity score matching analysis identified 854 matched patients, 414 PED and 440 NED. The population was mainly characterized by diabetic patients with CLI (80%) and high prevalence of CAD (30%), heart failure (15%) and renal insufficiency (20%). Mean follow-up length was 58 ± 34 months, (median 52.5). Mortality was 18% in NED vs 12% in PED patients at two years (p = 0.01), 36% vs 30% at 5 years (p = 0.03) and 41% vs 39% at seven years (p = 0.2) respectively. In patients ≤75 years, mortality at 7-year was 28% in PED vs 36% in NED, p = 0.07.
    CONCLUSIONS: These results suggest a reduced mortality at 2 and 5 years with PED as compare to NED treatment in a real-world CLI scenario. At 7-year follow-up, the advantage was numerically evident only in patients ≤75 years.
