Abstract
Recurrent intracranial aneurysms (IAs) often present with more complex morphology such as irregular shape, shallow height, and wide neck, which can make for challenging endovascular treatments.1 Initial rupture and interventions are associated with fibrotic changes and considerable alteration in the aneurysm configuration, which limits retreatment options and increases the risk of complications during retreatment.2 The Woven Endobridge (WEB) embolization device has demonstrated high efficacy, flexibility, and safety for the treatment of wide-neck bifurcation IAs, including ruptured and recurrent IAs, as shown in multiple retrospective studies and meta-analyses.3–8 Due to its optimal barrel shape, the WEB device is useful in the setting of previously treated aneurysms, particularly with wide-neck previously coiled aneurysms.1 9 10 In this technical video of four cases (video 1), we describe the technical nuances of WEB embolization for recurrent IAs, which were initially either coiled or clipped and demonstrated progressive growth with a wide-neck presentation on follow-up.
