Persistent flow inside the Woven EndoBridge at angiographic follow-up: A multicenter study.

ABSTRACT: BackgroundThe occurrence of persistent intra-device filling (BOSS 1, using the Bicêtre Occlusion Scale Score (BOSS)) in aneurysms treated with a Woven Endobridge (WEB) device is infrequent based on angiographic follow-up. To date, three monocentric case series were published studying BOSS 1 cases. Through a multicenter retrospective study, we aimed to report the incidence, and risk factors of intra-WEB persistent filling.MethodsWe reached out to European academic centers that treat patients using WEB devices and requested de-identified data of patients treated with a WEB device and underwent angiographic follow-up, at least 3 months after embolization, to assess the BOSS 1 occlusion score. We compared baseline characteristics, treatment modalities, and aneurysm data of the included BOSS 1
