Abstract

Background: Unfavorable aneurysm anatomy can make microwire navigation challenging, increasing the risk of complications. We present our experience of WEB-assisted microcatheterization in complex aneurysms.

Clinical presentation: Flow diversion was performed for three wide-neck large/giant intracranial aneurysms. A WEB was placed inside the sac, blocking the aneurysm neck and providing a contact surface to redirect the microwire across the aneurysm.

Conclusion: WEB-assisted microcatheterization appears an alternative strategy for the treatment of complex aneurysms.
