Résumé
The 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. We 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 patients with those of a control group consisting of non-BOSS 1 patients ( Among the pooled sample of 591 aneurysms treated with WEB, the rate of persistent flow (BOSS 1) at angiographic follow-up was 5.2% ( Persistent blood flow within the WEB device during angiographic follow-up (BOSS 1) is an uncommon occurrence. Our findings indicate that post-procedural dual antiplatelet therapy and undersizing of the WEB device are independently associated with the presence of BOSS 1 at follow-up.

CONCLUSION
CONCLUSIONS
Persistent blood flow within the WEB device during angiographic follow-up (BOSS 1) is an uncommon occurrence. Our findings indicate that post-procedural dual antiplatelet therapy and undersizing of the WEB device are independently associated with the presence of BOSS 1 at follow-up.
