Discussion & Conclusion:

• The WEB device offers a promising intrasaccular alternative to traditional coiling, particularly in wide-necked bifurcation aneurysms
• Procedure was completed successfully with no intra- or post-procedural complications
• This demonstrates feasibility and safety of the WEB device in acute aneurysmal settings
• Compared to conventional coiling, the WEB may provide:
  • Shorter procedure times
  • Less radiation to patient and surgeon
• Continued follow-up and imaging will be essential to assess long-term durability and occlusion status
