Intrasaccular flow disruption is a new and innovative treatment for intracranial aneurysms. In the first clinical experience with WEB dual layer (WEB-DL), the indications for treatment were ruptured or unruptured, wide-neck bifurcation aneurysms often challenging for the endovascular treatment. Initial series of the literature have shown a high feasibility of the treatment with low morbidity and no mortality. Anatomical results show a high rate of adequate occlusion (complete occlusion and neck remnant), some neck remnants being in fact just opacification of the proximal recess of the device. New WEB devices were recently developed (WEB-SL and WEB-SLS) and their introduction in clinical practice wills potentially enlarged indications for this treatment.
