Waffle-cone technique with Solitaire™ AB remodeling device: endovascular treatment of highly selected complex cerebral aneurysms.

Introduction: To evaluate patients with complex aneurysms who underwent waffle-cone stent-assisted coil embolization.

Methods: From February 2008 to February 2010, consecutive data were collected from 80 patients with aneurysms treated with the Solitaire™ AB Remodeling Device followed by a standard coiling procedure using bare or/and bioactive coils. Six of these patients were treated using the "waffle-cone-technique" placing the distal end of a stent directly into the base of a bifurcation aneurysm and coiling through the expanded and cone-shaped distal end of the stent allowing for preservation of parent artery patency.
