Woven EndoBridge embolization in the retreatment of basilar apex aneurysm

The Woven EndoBridge (WEB) device was approved by the U.S. FDA for its excellent angiographic occlusion of intracranial aneurysms and high safety profile, based on the landmark WEB-IT (WEB Intrasaccular Therapy) trial. There remains, however, a few cases of aneurysm recurrence that necessitate retreatment after the initial WEB procedure. In this technical video, the authors present the case of a middle-aged patient who showed significant basilar apex aneurysm recurrence and growth along with device compaction that required retreatment. Various aspects of treating aneurysms with a prior WEB device, including procedural technique, are discussed. The video can be found here: https://stream.cadmore.media/r10.3171/2022.7.FOCVID21152.
