Network Meta-analysis of Randomised Controlled Trials Comparing the Outcomes of Different Endovascular Revascularisation Treatments for Infra-inguinal Peripheral Arterial Disease Causing Chronic Limb Threatening Ischaemia. Eur J Vasc Endovasc Surg 2024; 68:246-254. [PMID: 38754723 DOI: 10.1016/j.ejvs.2024.05.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 04/19/2024] [Accepted: 05/09/2024] [Indexed: 05/18/2024]
Abstract
OBJECTIVE The aim of this study was to compare the efficacy of different endovascular revascularisation procedures for treating chronic limb threatening ischaemia (CLTI) using network meta-analysis (NMA). DATA SOURCES The databases PubMed and Cochrane Central Register for Controlled Trials were searched on 14 March 2023. REVIEW METHODS A NMA of randomised controlled trials (RCTs) reporting the efficacy of different endovascular revascularisation techniques for treating CLTI was performed according to PRISMA guidelines. The primary and secondary outcomes were major amputation and death, respectively. Random effects models were developed and the results were presented using surface under the cumulative ranking curve plots and forest plots. A p value of ≤ .050 was considered statistically significant. The Cochrane collaborative tool was used to assess risk of bias. RESULTS A total of 2 655 participants of whom 94.8% had CLTI were included. Eleven trials compared plain balloon angioplasty (PBA) vs. drug coated balloon (DCB) angioplasty (n = 1 771), five trials compared bare metal stent (BMS) vs. drug coated stent (DCS) (n = 466), three trials compared atherectomy vs. DCB (n = 194), two trials compared PBA vs. BMS (n = 70), one trial compared PBA vs. atherectomy (n = 50), and one trial compared BMS vs. DCB (n = 104). None of the revascularisation strategies significantly reduced the risk of major amputation or death compared with PBA. Using the network estimates, GRADE certainty of evidence for improvement in major amputation outcomes for DCB was moderate, for atherectomy and BMS was low, and for DCS was very low compared with PBA. Risk of bias was low in 16 trials, of some concerns in six trials, and high in one trial, respectively. CONCLUSION There is no current evidence from RCTs to reliably conclude that BMS, DCB, DCS, or atherectomy are superior to PBA in preventing major amputation and death in patients with CLTI. Larger comparative RCTs are needed to identify the best endovascular revascularisation strategy.

Abstract
PURPOSE This study aimed to evaluate the benefits and risks of patients with peripheral artery disease (PAD) treated with Absorb everolimus-eluting bioresorbable vascular scaffold (BVS) by analyzing all the published studies on the clinical characteristics of patients with PAD. MATERIALS AND METHODS PubMed, Embase, and the Cochrane Library were searched for relevant studies. Efficacy, safety, and basic characteristics were analyzed. RESULTS Four studies were included in meta-analysis, including a total number of 155 patients with PAD. The pooled overall primary patency, freedom from target lesion revascularization (TLR), symptom resolution, and wound healing were 90%, 96%, 94%, and 86%, respectively. The pooled perioperative complication and all-cause mortality were 4% and 9%, respectively. Preoperative total occlusion was detected in 43 of 192 lesions (22%). The mean lesion length was 27.26 mm. In terms of comorbidities, the pooled percentage of hypertension, hyperlipidemia, diabetes mellitus, coronary artery disease, chronic kidney disease history, and smoking were 65%, 74%, 49%, 43%, 20%, and 57%, respectively. CONCLUSION Among these studies, hypertension, hyperlipidemia, and diabetes mellitus were the most common comorbidities in patients with PAD. The Absorb everolimus-eluting BVS was safe and showed the favorable clinical outcomes in both patency and TLR, especially in infrapopliteal disease with heavy calcification. The conclusions of this meta-analysis still needed to be verified by more relevant studies with more careful design, more rigorous execution, and larger sample size.

Abstract
PURPOSE Endovascular treatment of femoropopliteal arterial diseases remains controversial. We conducted a Bayesian network meta-analysis of randomized controlled trials aiming to investigate the efficacy differences between paclitaxel- or sirolimus-eluting stents, covered stents, drug-coated balloons, bare metal stents, and percutaneous transluminal angioplasty. METHOD MEDLINE, Embase, Ovid, and other relevant online material were searched up to October 21, 2020. Primary endpoints were primary patency and target lesion revascularization at 6, 12, and more than 24 months. RESULTS Thirty-eight eligible trials included 6026 patients. In terms of primary patency, drug eluting stents were ranked as the most effective treatment based on the surface under the cumulative ranking curve values at 6 (80.6), 12 (78.4), and more than 24 months (96.5) of follow-ups. In terms of target lesion revascularization, drug eluting stents were ranked as the most effective treatment based on the surface under the cumulative ranking curve values at 6 (90.3), 12 (71.3), and more than 24 months (82.1) of follow-ups. Covered stents and bare metal stents had higher ranks in target lesion revascularization than those in primary patency. Sirolimus stents had a higher rank than paclitaxel stents. CONCLUSION Drug eluting stents showed encouraging results in primary patency rates and freedom from target lesion revascularization at all phases of follow-up for femoropopliteal arterial diseases. Sirolimus stents appear to be more effective in femoropopliteal segment than paclitaxel stent.

Long-term clinical outcome and mortality risks after paclitaxel-coated balloon angioplasty in patients with peripheral artery disease: An observational clinical study. Health Sci Rep 2021; 4:e236. [PMID: 33532599 PMCID: PMC7837675 DOI: 10.1002/hsr2.236] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Revised: 12/16/2020] [Accepted: 12/30/2020] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND AND AIMS Drug-eluting devices (DEDs) are usually used as a standard therapy for revascularization in femoropopliteal artery disease. Randomized controlled trails have found that DEDs with paclitaxel result in superior patency rates and decreased target lesion revascularization. A meta-analysis by Katsanos et al indicated an increased long-term mortality in patients treated with paclitaxel-coated devices. The aim of this observational clinical study was to assess the long-term clinical outcomes and mortality risk after paclitaxel-coated balloon angioplasty in patients with symptomatic peripheral artery disease. METHODS We retrospectively evaluated 287 patients with peripheral interventions, including 173 drug-coated balloon (DCB) angioplasties and 114 plain old balloon angioplasties (POBA), performed at our center between 2015 and 2018. RESULTS There were no significant differences in mortality rates between patients who received DCB angioplasty and those who received POBA. In the first year, the hazard ratio (HR) for DCB angioplasty was 0.59 (95% confidence interval [CI] 0.31 to 1.12, P = .104). After 2 years, this HR was 0.64 (95% CI 0.36-1.17, P = .145), while the 3-year and 4-year HR increased to 0.71 and 1.30 (3-year: 95% CI 0.37-1.33, P = ,283; 4-year: 95% CI 0.55-3.08, P = .546). No paclitaxel dose-response relationship with mortality rate was identified when adjusted for key predictors of mortality. CONCLUSIONS Analyses of patient level data identified no significant mortality differences between DCB angioplasty and POBA after 4 years of follow-up. Furthermore, there was no dose-response relationship between paclitaxel and mortality. These findings demonstrate that paclitaxel DCB is safe. Further long-term multicenter studies are needed to determine the risk of late mortality.

Abstract
BACKGROUND Endovascular therapy is often the preferred first treatment option for chronic limb threatening ischemia (CLTI) patients. Drug coated balloons (DCB) reduce restenosis rates compared to percutaneous transluminal angioplasty (PTA), however DCB use has not been studied systematically in patients with CLTI. Thus, the optimal treatment option for these complex lesions remains controversial. METHODS We report on 327 patients with CLTI treated either with DCB (n = 105) or non-DCB (n = 222) for femoropopliteal disease. Data were retrieved from the Excellence in Peripheral Artery Disease (XLPAD) registry (NCT01904851). Two DCB types were used at the discretion of the operator: Lutonix® (BARD Peripheral Vascular, Inc., Tempe, AZ, USA) and IN.PACT AdmiralTM (Medtronic, Santa Rosa, CA, USA). Odds ratios and the respective 95% confidence interval were synthesized to examine the association between the two groups in terms of all-cause mortality, target limb repeat endovascular or surgical revascularization, target vessel revascularization (TVR), major and minor amputation at 12 months of follow up. RESULTS The mean lesion length was 150.0 mm (SD:123.2) and 151.2 mm (SD:108.3) for the DCB and non-DCB group respectively. No difference between the two groups was detected in terms of all-cause mortality (2.86%vs2.7%,p = .94), target limb repeat endovascular or surgical revascularization (16.19%vs12.61%,p = .25), TVR (16.19%vs.11.71%,p = .26) or minor amputation (15.24%vs10.81%,p = .25) at 12 months of follow up. Although a higher incidence of 12 months major amputation was observed in the DCB group (11%vs.4%,p = .01), after adjusting for several risk factors the odds of major amputation were not statistically different between the DCB and non-DCB groups (OR:1.54;95%CI:0.53-4.51;p = .43). CONCLUSIONS Both DCB and non-DCB strategies are effective modalities for revascularization of patients with CLTI. No differences were identified between the DCB and non-DCB group in terms of late outcomes during 12 months of follow up.

Abstract
INTRODUCTION Endovascular treatment represents nowadays the preferred therapeutic approach for disabling femoro-popliteal arterial occlusive disease in fit patients. In the latest years, in order to improve short- and long-term outcomes, drug eluting devices have been developed. Drug coated balloons (DCB) and drug eluting stents (DES) are today employed in clinical practice, and several studies has been completed to assess their performance in different clinical scenarios. Objective of the present review and meta-analysis is to compare clinical results of different endovascular treatment modalities in the published literature in the last 10 years. EVIDENCE ACQUISITION A systematic review and meta-analysis following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement on the literature regarding direct comparisons between DCB, DES, bare metal stents (BMS) and Plain Old Balloon Angioplasty (POBA) has been conducted. Primary outcomes were considered Primary Patency and Target Lesion Revascularization (TLR) at 12 months. Analysis of late survival in different treatment groups was outside the scope of the present study and was therefore not included as main end point. EVIDENCE SYNTHESIS Meta analysis results confirm that DCB outperforms POBA in both primary patency (estimate OR=3.17, 95% CI: 2.10-4.76) and TLR (POBA estimate OR=3.59, 95% CI= 2.31-5.56). No clear evidences emerged comparing DES and BMS; however, DES were shown to fare better than BMS in terms of TLR when analyzing lesions <15 cm (OR 0.36, 95% CI: 0.35-0.36). Comparison of DCB and DES revealed higher rates of TLR for DES (OR 1.26 95% CI: 1.07-1.49), however no significant differences have been found regarding primary patency analyzing such long lesions (range 14-19.4 cm) as those included in the studies. CONCLUSIONS While confirming that DCB outperforms POBA in terms of primary patency and TLR at 12 months, only TLR benefits are noted for DES vs. BMS and DCB vs. DES in limited clinical settings. Further RCTs are needed to strongly assess the compared performance of drug eluting devices in relation to lesion length and controlling possible confounders.

Abstract
Vascular smooth muscle cell (SMC) phenotypic modulation contributes to the development of restenosis. A sorafenib-eluting stent was specifically designed to target SMC phenotypic modulation to inhibit in-stent restenosis in the present study. SMC contractile protein from the freshly isolated rat aorta was expressed at a high level, but its expression was dramatically reduced after SMCs were cultured in 10% FBS for 1 wk. After sorafenib treatment, SMC contractile protein expression was markedly upregulated. We further observed that Yes-associated protein (YAP) expression was attenuated after sorafenib treatment in a dose-dependent manner. Overexpression of YAP by lentivirus reversed the expression of sorafenib-induced SMC contractile protein and increased the expression of cyclin D. Mechanistically, sorafenib regulated the serum response factor-myocardin (SRF-Myocd) complex through competitive binding of YAP to Myocd and increased SRF binding to CArG-containing regions of SMC-specific contractile genes within intact chromatin, thereby controlling the activity of smooth muscle-specific gene transcription. In a rabbit carotid model, the sorafenib-eluting stent (SFES) dramatically inhibited in-stent restenosis and upregulated SMC contractile protein expression. Overexpression of YAP blocked the antirestenosis effect of SFES and repressed contractile smooth muscle-specific genes in vivo, indicating that SFES attenuated in-stent restenosis through YAP-mediated SMC phenotypic modulation. We demonstrated that SFES attenuated in-stent restenosis through YAP-mediated SMC phenotypic modulation. Targeting SMC phenotypic modulation by drug-eluting stent represents an attractive therapeutic approach for the treatment of occlusive vascular diseases.NEW & NOTEWORTHY In the present study, we demonstrated that sorafenib regulates smooth muscle cell (SMC) phenotypic modulation from a proliferative to a contractile state. Sorafenib induced a myocardin-serum response factor interaction and increased SMC contractile gene transcription through the Yes-associated protein pathway. Moreover, local delivery of sorafenib regulating SMC phenotypic modulation represents a promising strategy in the design of drug-eluting stents.
