Safety and efficacy of the woven endobridge device for treatment of ruptured intracranial aneurysms: A systematic review and meta-analysis

BACKGROUND: The Woven EndoBridge device has been increasingly used to treat wide-neck aneurysms, particularly ruptured ones. PURPOSE: Our aim was to investigate the safety and efficacy of the Woven EndoBridge device in the treatment of ruptured intracranial aneurysms. DATA SOURCES: All studies evaluating the outcomes of Woven EndoBridge device use in the treatment of ruptured intracranial aneurysms from inception through 2020 were searched on Ovid Evidence-Based Medicine Reviews, EMBASE, MEDLINE, Scopus, and the Web of Science Core Collection. STUDY SELECTION: Eighteen studies encompassing 487 patients with 496 ruptured aneurysms treated with the Woven EndoBridge device were included. DATA ANALYSIS: We studied rates of rerupture and retreatment, angiographic outcomes at the last follow-up point, complications, and mortality rates. Data were collected on anticoagulation and antiplatelet use. Meta-analysis was performed using the random effects model. DATA SYNTHESIS: The rate of late rebleeding was 1.1% (95% CI, 0.1%-2.1%). The treatment-related perioperative complication rate and the overall clinical complication rate were 13.2% (95% CI, 9.2%-17.2%) and 3.2% (95% CI, 1.6%-4.7%), respectively. Thirteen hemorrhagic (2%; 95% CI, 0.8%-3.3%) and 41 thromboembolic (6.8%; 95% CI, 4.6%-9%) complications occurred. Favorable clinical outcomes were achieved in 85% of patients. Procedure-related mortality and overall mortality rates were 2.1% (95% CI, 0.8%-3.3%) and 11.5% (95% CI, 7%-16%), respectively. At last follow-up, an adequate occlusion rate was 87.3% (95% CI, 82.1%-92.4%) and the retreatment rate was 5.1% (95% CI, 3%-7.3%). LIMITATIONS: Our meta-analysis is limited by selection bias and high heterogeneity. CONCLUSIONS: This meta-analysis demonstrated the safety and efficacy of the Woven EndoBridge device in the management of ruptured aneurysms, but further studies are needed.
