P-046 Factors associated with incomplete occlusion of intracranial aneurysms at follow up after treatment with woven endobridge (WEB) device

Purpose We present core-lab adjudicated immediate post-proce-dural angiographic outcomes following endovascular treatment of side wall and bifurcation wide-necked aneurysms using MICRUSFRAME and GALAXY coils and various adjunctive devices within the STERLING registry. Methods STERLING is an ongoing single-arm prospective post-market surveillance registry evaluating ruptured/unrup-tured aneurysms treated with MICRUSFRAME and GALAXY coils (Cerenovus, Irvine, CA). All cases of wide-neck aneurysm treatment (neck > 4 mm or dome-to-neck ratio < 2) were extracted from the registry. Subgroups were defined according to the adjunctive devices (if any) used during treatment. The primary outcome measures were core-lab adjudicated modified Raymond-Roy (mRR) occlusion at final procedural angiogram, and procedure-related adverse events.
