Diverse Use of the WEB Device: A Technical Note on WEB Stenting and WEB Coiling of Complex Aneurysms

Abstract:

The Woven EndoBridge (WEB) device, an intrasaccular flow-diverter that does not require long-term antiplatelet use, has recently emerged as an alternative to embolize complex intracranial aneurysms; however, there are limitations to the WEB device. First, it does not immediately secure the aneurysm in most subarachnoid hemorrhage cases. Second, it may not be suitable for embolization of wide-neck aneurysms with an unfavorable aspect ratio. To overcome these limitations, we have used the WEB device in conjunction with stenting and/or coiling. Here, we present a technical note with an illustrated case series and provide a detailed step-by-step description on how the WEB device can be used in adjunct to coiling and/or stenting to achieve successful angiographic results. Accurate sizing of the WEB device before deployment is critical. Larger case series are required to further assess the safety and success of these combined techniques.
