Multiple intra-aneurysmal WEB devices: Case discussions and operative technique

Abstract:

The Woven Endobridge (WEB, Sequent Medical, Aliso Viejo, California) device has emerged as an FDA approved endosaccular flow diverting alternative for patients with complex aneurysm morphology. We describe for the first time, in patients with dual anti platelet therapy (DAPT) non compliance, two cases during which multiple WEB devices were deployed within the aneurysm sac to achieve flow disruption. Two ophthalmic segment internal carotid artery aneurysms are treated by the deployment of an additional WEB device within the sac. We subsequently discuss the techniques utilized to ensure parent vessel patency. We demonstrate that patients with contraindications to endovascular modalities requiring DAPT may be candidates for a multi WEB intra-aneurysmal construct.
