“…We reviewed 4 studies (3 retrospective cohorts and 1 prospective cohort) with a total of 527 patients. Three studies focused on comparative outcomes between Ellipsys Vascular Access System and surgery 16 , 17 , 18 and 1 focused on the WavelinQ EndoAVF System. 19 The baseline characteristics are presented in Table 1 , and the results of our studies are summarized in Table 2 .…”

“…We reviewed the articles on the following parameters: the representativeness of exposed cohort, selection of nonexposed cohort, ascertainment of exposure, demonstration that outcome of interest was not present at the start of study, comparability of cohorts on the basis of design or analysis, assessment of outcome, follow-up length, and loss to follow-up. Most studies scored higher than 6; however, the study by Harika et al 16 reported bias for comparability of cohorts, Osofsky et al 18 reported bias due to patients lost to follow-up, and Shahverdyan et al 17 reported bias due to the limited follow-up time of patients.…”

“…Several single-arm studies have demonstrated promising results with both WavelinQ (Beckton Dickinson and Company, Franklin Lakes, New Jersey, USA) and the Ellipsys Vascular Access System (Medtronic, Minneapolis, Minnesota, USA) [21][22][23][24][25][26][27][28][29] . Moreover, limited single-center comparison studies have been published, comparing WavelinQ pAVF to RCAVF, and Ellipsys pAVF to surgical RCAVF and BCAVF 30 as well as to similarly located surgical proximal forearm "Gracz" AVF 31 . These provide insightful comparable data between sAVF and pAVF that should be considered in conjunction with several limitations preventing accurate comparison (i.e., AVF location, anatomical suitability for pAVF, blood vessels and different AVF creation techniques).…”

“…After removing duplicates, we identified 2838 studies during the search conducted until May 2021. We identified eight studies that fulfilled all eligibility criteria and we included them in the qualitative synthesis [ 15 - 22 ]. After excluding one ongoing study (protocol without results) [ 22 ], a total pooled sample of 860 patients (eAVF group, n = 429 patients; sAVF group, n = 431) from seven studies (six single-center observational studies and one population-based study) was included in the quantitative synthesis (Figure 1 ).…”

An endovascular arteriovenous fistula is a recent technological advancement in hemodialysis vascular access. This systematic review and meta-analysis aimed to investigate the efficacy and safety of endovascular arteriovenous fistula (eAVF) creation compared with surgical arteriovenous fistula (sAVF) creation among patients with chronic kidney disease. We searched Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Clinical Trials.gov , and the WHO International Clinical Trials Registry Platform until May 2021 to perform meta-analyses using random-effects models. Pre-specified primary outcomes were fistula maturation, procedure-related complications, and patient satisfaction. Secondary outcomes were procedural technical success, procedure time, all adverse events, and medical expenditure. The risk of bias in non-randomized studies of the interventions assessment tool, and the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) approach were used to assess the quality of individual studies and the body of evidence, respectively. In seven studies including 860 patients, endovascular arteriovenous fistula creation had little to no effect on fistula maturation (odds ratio, 0.58; 95% confidence intervals, 0.05 to 6.91). Meta-analysis could not be performed for procedure-related complications and patient satisfaction due to insufficient data. For secondary outcomes, endovascular arteriovenous fistula resulted in a slight to no difference in procedural technical success (odds ratio, 0.69: 95% confidence intervals, 0.04 to 11.98) and all adverse events (odds ratio, 6.31; 95% confidence intervals, 0.64 to 62.22). Endovascular fistula creation incurred less medical expenditure than sAVF (mean difference, USD 12760; 95% confidence intervals, -19710 to -5820). Meta-analysis for procedure time was not performed because one of the studies had a critical risk of bias. All of these outcomes were of low certainty of evidence or very low certainty of evidence. There was limited evidence for supporting endovascular arteriovenous fistula creation over conventional surgical arteriovenous fistula creation for patients with chronic kidney disease. Multicenter randomized controlled trials are needed to confirm the efficacy and safety of eAVFs in selected populations.
