Subgroup analyses by IA rupture status were also conducted for the primary outcomes.</p><p><strong>Results: </strong>Eleven studies with 880 patients and 933 IAs were included. Regarding efficacy, the rate of adequate occlusion at last follow-up was 91% (95% CI 86%-94%) and the complete occlusion rate was 69% (95% CI 65%-73%). Safety outcomes demonstrated a composite complication rate of 7% (95% CI 4%-11%), an intraprocedural complication rate of 7% (95% CI 5%-9%; I2 = 0%), and a postprocedural complication rate of 2% (95% CI 1%-5%; I2 = 0%). No differences were found between WEB-17 and pvWEB in terms of adequate occlusion (WEB-17: 87.7% vs pvWEB: 80.4%; OR = 1.35, 95% CI 0.71-2.55) and safety composite outcome (WEB-17: 8.7% vs pvWEB: 10%; OR = 1.05, 95% CI 0.51-2.16). Subgroup analysis did not evidence heterogeneity between subgroups.</p><p><strong>Conclusions: </strong>The WEB-17 device demonstrates promising efficacy and safety profiles for the treatment of IAs. However, these results should be interpreted with caution due to the limited quality of evidence in the included studies. Further prospective, randomized studies are needed to validate these findings.</p>","PeriodicalId":47358,"journal":{"name":"Neuroradiology Journal","volume":" ","pages":"19714009251317505"},"PeriodicalIF":1.3,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11775924/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143053862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
