Woven Endobridge Device (WEB)-assisted coiling of a large MCA-aneurysm: Case report and technical note

The Woven Endobridge (WEB) device serves as an endosaccular flow-disruptor in the treatment of wide-necked cerebral aneurysms. Despite the varying availability of different WEB sizes, there are still limitations. Especially aneurysms with an width and height larger than 10 mm and 10.4 mm pose a particular challenge. Here we present a case report and technical note in the treatment of a large middle cerebral artery (MCA) aneurysm using the WEB device and adjunctive coiling. WEB-assisted coiling (WAC) of large aneurysms is a rarely described technique that allows intrasaccular embolization alone without the need for intracerebral stent-ing. Accurate sizing of the WEB device is very important in such cases. However, aneurysm recurrence must be considered and may require further treatment. More research is needed to further evaluate the safety and success of this technique.
