Comparison of Clinical Effectiveness and Safety of Drug-Coated Balloons versus Percutaneous Transluminal Angioplasty in Arteriovenous Fistulae: A Review of Systematic Reviews and Updated Meta-Analysis. J Vasc Interv Radiol 2024:S1051-0443(24)00266-5. [PMID: 38554948 DOI: 10.1016/j.jvir.2024.03.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 02/14/2024] [Accepted: 03/23/2024] [Indexed: 04/02/2024] Open
Abstract
PURPOSE To evaluate the clinical effectiveness and safety of drug-coated balloons (DCBs) compared with those of percutaneous transluminal angioplasty (PTA) for arteriovenous fistula (AVF) stenosis via a review of systematic reviews (SRs) and an update of the current meta-analysis. MATERIALS AND METHODS Literature was searched to retrieve SRs comparing DCBs and PTA for AVFs. A narrative review of SRs and pooled analysis were performed. RESULTS Eleven SRs were included. DCBs demonstrated favorable outcomes at 6 and 12 months compared with PTA, with improved patency in 7 SRs and a trend toward favorable outcomes without statistical significance in 3 SRs. Target lesion revascularization (TLR) was reported in 3 SRs; 2 reviews reported a significantly lower incidence in the DCB group than in the PTA group, whereas 1 review reported no significant differences at 12 months. Four studies reporting all-cause mortality revealed no significant difference between the 2 treatments. In the updated meta-analysis including 23 studies, DCBs demonstrated improved primary patency at 6 months (risk ratio [RR], 1.27; 95% CI, 1.07-1.50) and 12 months (RR, 1.36; 95% CI, 1.19-1.55) and were associated with a lower incidence of TLR at 6 months (RR, 0.54; 95% CI, 0.41-0.73) and 12 months (RR, 0.78; 95% CI, 0.62-0.99). There was no difference in mortality between the 2 groups for 24 months. CONCLUSIONS A review of SRs and meta-analysis update revealed the consistent benefits of DCBs over PTA in treating AVFs in terms of primary patency and TLR. Compared with PTA, DCBs do not increase mortality risk.

Abstract
Objective To compare the efficacy of angioplasty using drug-eluting balloons (DEB) compared with plain old balloon angioplasty (POBA) to reduce the rate of restenosis. Methods This prospective, single-centre, single-blinded, 1:1 randomized, clinical trial enrolled patients that had primary or restenotic lesions in native upper extremity arteriovenous (AV) fistulas or at the graft-venous anastomosis. Patients were randomized to angioplasty with a POBA or a DEB. The primary effectiveness endpoints were freedom from target lesion revascularization (TLR) and functional status of access circuit at 12 months. Results A total of 42 (28 male, 14 female; age range, 42–83 years) patients were enrolled. Patients were followed for 12 months. No significant differences were detected between the POBA and DEB groups regarding total number of TLR procedures (31 versus 36, respectively), freedom from TLR (3 versus 4, respectively) and functional status of the access circuit at 12 months (14 of 20 patients [70%] versus 17 of 22 patients [77%], respectively). Conclusion This clinical trial did not demonstrate any significant differences between DEB angioplasty and standard balloon angioplasty when treating dysfunctional haemodialysis access.

Abstract
Purpose To compare the efficacy and safety between paclitaxel coated balloon (PCB) angioplasty and conventional balloon (CB) angioplasty in the treatment of dysfunctional arteriovenous fistula (AVF). Methods We searched four major electronic databases (PubMed, EMBASE, Web of Science and the Cochrane Library) for randomized controlled trials (RCTs) published from inception through November 28, 2021. Outcomes of interest included target lesion primary patency (TLPP), technical success and all-cause mortality. The STATA package version 15.1 was utilized to undertake meta-analyses. Results Fourteen RCTs totaling 1535 patients were analyzed. The available data showed that there were no significant differences of TLPP rates at 3, 6, 9 and 12 months between the PCB group and the CB group (risk ratio (RR) 1.00, 95% confidence interval (CI) 0.93–1.07, p = 1.000, I2 = 33.5%, Cochrane Q test p = 0.185, fixed-effect model; RR 1.17, 95% CI 0.99–1.39, p = 0.065, I2 = 75.4%, Cochrane Q test p = 0.000, random-effect model; RR 0.81, 95% CI 0.35–1.89, p = 0.625, I2 = 62.8%, Cochrane Q test p = 0.045, random-effect model; RR 1.19, 95% CI 0.97–1.47, p = 0.096, I2 = 40.5%, Cochrane Q test p = 0.071, random-effect model). In addition, two groups had similar technical success rates (RR 1.00, 95% CI 0.97–1.03, p = 1.000, I2 = 0.0%, Cochrane Q test p = 0.596, fixed-effect model) and all-cause mortality rates (RR 1.00, 95% CI 0.54–1.84, p = 1.000, I2 = 0.0%, Cochrane Q test p = 0.599, fixed-effect model). Conclusions PCB angioplasty did not appear to convey any obvious advantage over CB angioplasty in the treatment of dysfunctional AVF. However, further multi-center, large-scale and well-designed RCTs are needed to prove outcomes.

Morphological Lesion Types Are Associated with Primary and Secondary Patency Rates after High-Pressure Balloon Angioplasty for Dysfunctional Arteriovenous Fistulas. Blood Purif 2021; 51:425-434. [PMID: 34320498 DOI: 10.1159/000516883] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Accepted: 04/07/2021] [Indexed: 11/19/2022]
Abstract
BACKGROUND Neointimal hyperplasia (NIH) is believed to be the main reason for arteriovenous fistula (AVF) dysfunction, but other mechanisms are also recognized to be involved in the pathophysiological process. This study investigated whether different morphological types of AVF lesions are associated with the patency rate after percutaneous transluminal angioplasty (PTA). METHODS This retrospective study included 120 patients who underwent PTA for autogenous AVF dysfunction. All the cases were evaluated under Doppler ultrasound (DU) before intervention and divided into 3 types: Type I (NIH type), Type II (non-NIH type), and Type III (mixed type). Prognostic and clinical data were analyzed by Kaplan-Meier analysis and the Cox proportional hazards model. RESULTS There was no statistical difference in baseline variables among groups, except for lumen diameter. The primary patency rates in Type I, Type II, and Type III groups were 78.4, 93.2, and 83.2% at 6 months and 59.5, 84.7, and 75.5% at 1 year, respectively. The secondary patency rates in Type I, Type II, and Type III groups were 94.4, 97.1, and 100% at 6 months and 90.5, 97.1, and 94.7% at 1 year, respectively. The Kaplan-Meier curve showed that the primary and secondary patency rates of Type I group were lower than those of Type II group. Multivariable Cox regression analysis demonstrated that postoperative primary patency was correlated with end-to-end anastomosis (hazard ratio [HR] = 2.997, p = 0.008, 95% confidence interval [CI]: 1.328-6.764) and Type I lesion (HR = 5.395, p = 0.004, 95% CI: 1.730-16.824). CONCLUSIONS NIH-dominant lesions of AVF evaluated by DU preoperatively were a risk factor for poor primary and secondary patency rate after PTA in hemodialysis patients.

Abstract
Advances in standards of care have extended the life expectancy of patients with kidney failure. However, options for chronic vascular access for haemodialysis - an essential part of kidney replacement therapy - have remained unchanged for decades. The high morbidity and mortality associated with current vascular access complications highlights an unmet clinical need for novel techniques in vascular access and is driving innovation in vascular access care. The development of devices, biological approaches and novel access techniques has led to new approaches to controlling fistula geometry and manipulating the underlying cellular and molecular pathways of the vascular endothelium, and influencing fistula maturation and formation through the use of external mechanical methods. Innovations in arteriovenous graft materials range from small modifications to the graft lumen to the creation of completely novel bioengineered grafts. Steps have even been taken to create new devices for the treatment of patients with central vein stenosis. However, these emerging therapies face difficult hurdles, and truly creative approaches to vascular access need resources that include well-designed clinical trials, frequent interaction with regulators, interventionalist education and sufficient funding. In addition, the heterogeneity of patients with kidney failure suggests it is unlikely that a 'one-size-fits-all' approach for effective vascular access will be feasible in the current environment.

Abstract
Objective To report the mid-term results of a single-center randomized controlled trial comparing drug-coated balloon angioplasty (DBA) and plain balloon angioplasty (PBA) for the treatment of dysfunctional radiocephalic arteriovenous fistulas (RCAVFs). Materials and Methods In this prospective study, 39 patients (mean age, 62.2 years; 21 males, 18 females) with RCAVFs failing due to juxta-anastomotic stenosis were randomly assigned to undergo either both DBA and PBA (n = 20, DBA group) or PBA alone (n = 19, PBA group) between June 2016 and June 2018. Primary endpoints were technical and clinical success and target lesion primary patency (TLPP); secondary outcomes were target lesion secondary patency (TLSP) and complication rates. Statistical analysis was performed using the Kaplan-Meier product limit estimator. Results Demographic data and baseline clinical characteristics were comparable between the groups. Technical and clinical success rates were 100% in both groups. There was no significant difference between the groups in the mean duration of TLPP (DBA group: 26.7 ± 3.6 months; PBA group: 27.0 ± 3.8 months; p = 0.902) and TLSP (DBA group: 37.3 ± 2.6 months; PBA group: 40.4 ± 1.5 months; p = 0.585). No procedural or post-procedural complications were identified. Conclusion Paclitaxel-coated balloon use did not significantly improve TLPP or TLSP in the treatment of juxta-anastomotic stenosis of dysfunctional RCAVFs.

Abstract
OBJECTIVE The comparison between paclitaxel-coated balloon (PCB) angioplasty and plain balloon angioplasty (PBA) for hemodialysis (HD) access stenosis or occlusion has not been well investigated. The objectives of this systematic review and meta-analysis were to compare all-cause mortality, HD access primary patency, and circuit primary patency after endovascular maintenance procedures using PCB angioplasty vs PBA. METHODS MEDLINE, Embase, and Cochrane Databases were systematically searched to identify all the relevant studies on paclitaxel-coated devices for stenosis or thrombosis of HD access. A random effects model was applied to pool the effect measures. Dichotomous data were presented using an odds ratio (OR). Effect data were presented using pooled hazard ratio (HR) with 95% confidence interval (CI). RESULTS A total of 16 studies were included in this meta-analysis, 12 randomized controlled trials and 4 cohort studies involving 1086 patients who underwent endovascular treatment for HD access stenosis or occlusion. All-cause mortality rates at 6, 12, and 24 months after intervention were similar between the PCB and PBA groups (6 months: OR, 1.06 [95% CI, 0.38-2.96; P = .907; I2 = 19.2%]; 12 months: OR, 1.20 [95% CI, 0.66-2.16; P = .554; I2 = 0%]; 24 months: OR, 1.43 [95% CI, 0.83-2.45; P = .195; I2 = 0%]). There was a significant improvement of primary patency in the PCB group compared with the PBA group (HR, 0.47; 95% CI, 0.33-0.69; P < .001; I2 = 67.3%). This benefit was consistent with the analysis of randomized controlled trials, whereas cohort studies were excluded. Further subgroup analysis of target lesions demonstrated that primary patency was significantly higher in the PCB group than in the PBA group, not only for arteriovenous fistula (HR, 0.54; 95% CI, 0.30-0.98; P = .041; I2 = 76.8%) but also for central venous stenosis (HR, 0.39; 95% CI, 0.22-0.71; P = .002; I2 = 0%). The PCB group was associated with higher 6-month (OR, 0.40; 95% CI, 0.27-0.59; P < .001) and 24-month lesion primary patency (OR, 0.28; 95% CI, 0.11-0.72; P = .009) than PBA and was marginally associated with 12-month lesion primary patency (OR, 0.52; 95% CI, 0.26-1.03; P = .06). Circuit primary patency analysis showed a marginal trend toward better outcome in the PCB group (HR, 0.63; 95% CI, 0.40-1.00) but no statistical significance (P = .052). CONCLUSIONS This systematic review and meta-analysis demonstrated that PCB angioplasty is associated with significantly improved primary patency of arteriovenous fistula and central venous stenosis for HD access maintenance, with no evidence of increasing all-cause mortality based on short-term and midterm follow-up. Further large cohort study is needed to investigate long-term mortality.

Abstract
Endovascular salvage plays an important role in dialysis access care. Angioplasty using standard high- and ultrahigh-pressure balloon is the mainstay of therapy, while the use of cutting balloons and balloons designed to deliver pharmacologically active agents to the site of recurrent stenosis is demonstrating improved performance for specific targets that have to be further defined. Stents and stent grafts are additional tools for use at access segments predisposed for inward remodeling such as the cephalic arch or basilic swing point. The juxta-anastomotic segment has particular relevance in maturation of autogenous accesses as well as maintenance of access flow volume. Depending on the location of the access in the forearm or upper arm, and which artery is feeding into the access vein, any type of balloon angioplasty and stent or stent graft placement may be used to establish and maintain patency. Successful management of dialysis access options relies on preservation of venous real estate during the chronic kidney disease phase of kidney disease as well as on knowledgeable evaluation of arm veins and the access by physical examination, bed side ultrasound, and angiographic studies.

Abstract
BACKGROUND Juxta-anastomotic stenosis is a common issue of arteriovenous fistulas. We aimed to evaluate the results of percutaneous transluminal angioplasty with drug-coated balloon versus plain balloon for the treatment of juxta-anastomotic stenoses of mature but failing distal radiocephalic arteriovenous fistulas. METHODS A total of 80 patients with a juxta-anastomotic stenosis of distal radiocephalic arteriovenous fistula in our clinic between January 2016 and September 2017 were retrospectively analyzed. Patients were divided into two groups according to the type of treatment as drug-coated balloon - percutaneous transluminal angioplasty (n = 44) and plain balloon - percutaneous transluminal angioplasty (n = 43). Intra- and post-procedural data were recorded. Target lesion primary patency rate was evaluated at 6 and 12 months. Of all patients, 48 were females and 39 were males with a mean age of 56.3 ± 10.4 (range, 24-75) years. Both groups had mature fistulas, and the mean age of fistula was 11.3 ± 9.1 months in the drug-coated balloon - percutaneous transluminal angioplasty group and 10.3 ± 8.8 months in the plain balloon - percutaneous transluminal angioplasty group (p = 0.24). RESULTS There was no significant difference in the target lesion stenosis rate and the median lesion length between the groups. Technical and clinical success were achieved in both groups. Target lesion primary patency was similar at 6 months between the two groups (93.1% vs 81.3%, respectively; p = 0.14) but significantly higher for the drug-coated balloon - percutaneous transluminal angioplasty group at 12 months (81.8% vs 51.1%, respectively; p = 0.01). CONCLUSION Our study results suggest that the use of drug-coated balloon combined with percutaneous transluminal angioplasty is an effective treatment for juxta-anastomotic stenoses of mature but failing distal radiocephalic arteriovenous fistulas with significantly improved target lesion primary patency rates and reduced need for juxta-anastomotic reinterventions.

Abstract
BACKGROUND Arteriovenous fistula is the most preferred form of vascular access, but stenosis treated by balloon angioplasty is prone to restenosis. Multiple trials have been published with regard to the use of paclitaxel-coated balloon to prolong lesion patency compared to conventional balloon. Although paclitaxel-coated balloon has theoretical appeal, its use has not been widespread nationwide due to cost and lack of large-scale multicenter studies. We performed this meta-analysis to evaluate whether paclitaxel-coated balloon outperforms conventional balloon to prolong target lesion patency. METHODS PubMed/Medline, Clinical Trials.gov, EMBASE, Scopus, Web of Science, and Cochrane Central were searched from inception through April 2019 for studies that investigated the use of paclitaxel-coated balloon in arteriovenous fistula. RESULTS Ten studies were included in the final meta-analysis: six studies were randomized controlled trials and four studies were cohort studies. There were 911 participants with a mean age of 64.78 (±5.96) years, and 61.89% were male. Outcome of interest was target lesion primary patency, recorded at 1, 3, 6, 7, 12, and 24 months. Meta-analysis of randomized controlled trials shows that paclitaxel-coated balloons did not statistically improve target lesion primary patency compared to conventional balloons at months 1 (odds ratio = 1.54, p = 0.6373), 3 (odds ratio = 0.57, p = 0.0575), 6 (odds ratio = 0.65, p = 0.3644), 7 (odds ratio = 0.63, p = 0.0582), 12 (odds ratio = 0.64, p = 0.0612), and 24 (odds ratio = 0.43, p = 0.3452). Effect of paclitaxel-coated balloons was statistically significant for cohort studies at months 6 (odds ratio = 0.26, p = 0.0007), 12 (odds ratio = 0.21, p = 0.0001), and 24 (odds ratio = 0.23, p = 0.01). CONCLUSION Paclitaxel-coated balloon showed no statistically significant improvement over conventional balloons in decreasing fistula stenosis in randomized controlled trial but were significant for cohort studies.
