Abstract

The Woven EndoBridge (WEB; MicroVention, Aliso Viejo, CA, USA) intrasaccular flow disruptor is a therapeutic option for wide neck bifurcation intracranial aneurysms that does not require the use of adjunctive techniques such as stents or balloon remodeling. As with other endovascular devices, displacement of the WEB is a recognized complication. Few reports have been published regarding the management of this type of complication. We describe a case of retrieval of a displaced WEB using a Solitaire Platinum revascularization device (Medtronic, Minneapolis, MN, USA). Interventionists should be aware of this option in the management of such a complication.

  Fig. 1. Displacement of Woven EndoBridge (WEB; MicroVention, Aliso Viejo, CA, USA) device. (A) 3-D angiograms showed basilar tip aneurysm. (B) WEB device initially deployed within aneurysm lumen; arrows indicate proximal and distal markers of the WEB. (C) During detachment, the WEB (arrows) was displaced into the distal basilar artery.

  Fig. 2. Retrieval of Woven EndoBridge (WEB; MicroVention, Aliso Viejo, CA, USA) device. (A) Microwire and microcatheter (white arrow) were navigated past WEB (black arrows) into the left posterior cerebral artery. (B) Solitaire Platinum (Medtronic, Minneapolis, MN, USA) (white arrows indicate distal markers) was deployed past WEB (black arrows). (C) WEB (black arrows) was captured inside SOFIA catheter (MicroVention) (white arrow denotes catheter tip). (D) New WEB device (arrows) was satisfactorily deployed and detached. Slightly increased opacification inside the aneurysm lumen denotes stasis of flow. (E) Follow-up magnetic resonance angiography at 3 months shows occlusion of the aneurysm.
