BACKGROUND: The WEB device is a recent intrasaccular flow disruption technique developed for the treatment of wide-necked @entity438 . To date, a single report on the WEB Single-Layer (SL) treatment of @entity438 has been published with 1-months' safety results. The aim of this study is to report our experience and 6-month clinical and angiographic follow-up of endovascular treatment of @entity439 with the WEB SL. METHODS: Ten @entity1 with 10 unruptured wide-necked @entity439 were prospectively enrolled in this study. Feasibility, intraoperative and postoperative complications, and outcomes were recorded. Immediate and 6-month clinical and angiographic results were evaluated. RESULTS: Failure of WEB SL placement occurred in two cases. Eight @entity439 were successfully treated using one WEB SL without additional treatment. Three middle cerebral artery, four anterior communicating artery, and one basilar artery @entity439 were treated. Average dome width was 7.5   mm (range 5.4-10.7   mm), and average neck size was 4.9   mm (range 2.6-6.5   mm). No periprocedural complication was observed, and morbi-mortality at discharge and 6 months was 0.0%. Angiographic follow-up at 6 months demonstrated complete @entity439 in 2/8 @entity439 , neck remnant in 5/8 @entity439 , and @entity439 remnant in 1/8 @entity439 . CONCLUSIONS: From this preliminary study, treatment of bifurcation @entity438 using WEB SL is feasible. WEB SL treatment seems safe at 6 months; however, the rate of neck remnants is not negligible due to compression of the WEB SL. Further technical improvements may be needed in order to ameliorate the occlusion in the WEB SL treatment.
