    AbstractBackground: Prospective single and multicenter studies have shown improved outcomes of patients who underwent carotid artery stenting with the novel CGuard dual-layer mesh stent at 1 year. Objectives: The aim of this study is to conduct a systematic review and meta-analysis of all published studies to assess 1-year efficacy and outcomes of CGuard in patients with carotid stenting. Methods: A systematic search was performed. All studies enrolling at least 20 patients were included in our analysis. The primary endpoints were death (all-cause, cardiovascular and ipsilateral stroke-related death) and stroke rate at 1 year. The secondary endpoint was in-stent restenosis at 1 year. Results: The final analysis included 1709 patients. The one-year all-cause mortality rate was 2.97% (39/1699, 95% CI: 1.26-6.86%, I2 = 67%, t2 = 0.3442, p < 0.01), cardiovascular-related death was 0.92% (10/1616, 95% CI: 0.35-2.39%, I2 = 34%, t2 = 0.2302, p = 0.18), and ipsilateral stroke-related death was 0.3% (1/1649, 95% CI: 0.1-0.87%, I2 = 0%, t2 = 0, p = 0.69). The one-year ipsilateral stroke rate was 1.21% (16/1649, 95% CI: 0.58-2.5%, I2 = 28%, t2 = 0.1433, p = 0.23), transient ischemic attacks (TIAs) rate was 1.78% (19/1149, 95% CI: 1.11-2.84%, I2 = 0%, t2 = 0, p = 0.69), and total composite 1-year stroke/TIA rate was 2.97% (32/1149, 95% CI: 1.84-4.77%, I2 = 0%, t2 = 0, p = 0.41). The in-stent restenosis rate at 1 year was 1.06% (13/1653, 95% CI: 0.48-2.34%, I2 = 28%, t2 = 0.2308, p = 0.22). Conclusions: This meta-analysis shows that CAS with CGuard is safe with minimal neurological adverse events and in-stent restenosis rate at 1 year.
