OBJECTIVE: To compare contrast-enhanced MR angiography (CE-MRA) and DSA for the follow-up of intracranial aneurysms (IAs) treated with the Woven EndoBridge embolization system DL (WEB DL; Sequent Medical, Aliso Viejo, California, USA). MATERIALS AND METHODS: We retrospectively identified all patients treated with a WEB DL between November 2010 and February 2013 in 2 hospitals. The IA occlusion was graded on follow-up CE-MRA and DSA by 4 independent readers and by 2 readers reaching a consensus, respectively...

BACKGROUND AND PURPOSE: WEBCAST is a European study dedicated to the evaluation of the feasibility, safety, and efficacy of endovascular treatment with WEB of intracranial aneurysms. MATERIALS AND METHODS: The study was conducted in 10 European centers. Inclusion criteria were aneurysms located at internal carotid artery bifurcation, middle cerebral artery, basilar artery, and anterior communicating artery with a neck ≥4 mm and a dome to neck ratio ≥ 1. Recanalized aneurysms were not included...

BACKGROUND AND PURPOSE: Flow disruption with the WEB-DL device has been used safely for the treatment of wide-necked bifurcation aneurysms but the stability of aneurysm occlusion after this treatment is unknown. This retrospective multicenter European study analyzed short- and midterm data in patients treated with WEB-DL. METHODS: Twelve European neurointerventional centers participated to the study. Clinical data, pre- and post-operative, short-, and midterm images were collected...

OBJECTIVE: The WEB (WEB aneurysm embolization system, Sequent Medical, Aliso Viejo, California, USA) is a self-expanding, nitinol, mesh device designed to achieve aneurysm occlusion after endosaccular deployment. The WEB Occlusion Scale (WOS) is a standardized angiographic assessment scale for reporting aneurysm occlusion achieved with intrasaccular mesh implants. This study was performed to assess the interobserver variability of the WOS. METHODS: Seven experienced neurovascular specialists were trained to apply the WOS...

INTRODUCTION: The Woven Endobridge (WEB II) device (Sequent Medical, Inc., Aliso Viejo, CA, USA) is an intra-saccular, oblate, braided-wire embolization device designed to provide flow disruption at the aneurysm neck-parent artery interface. The purpose of this study was to evaluate the acute and short-term performance of the WEB II device regarding the immediacy, degree, and durability of aneurysm occlusion in two patients. METHODS: The WEB II device was implanted in one patient with an unruptured MCA trifurcation aneurysm and one patient with an unruptured basilar tip aneurysm...
