Intraaneurysmal balloon assistance for navigation across a wide-necked aneurysm.
Endovascular obliteration of wide-necked aneurysms may be precluded by the inability to navigate across the aneurysm neck. The authors present a technique in which a Hyperform balloon is inflated within the aneurysm and used as a contact surface to "bounce" the remodeling balloon across the aneurysm neck. They have successfully used this technique in 3 patients to efficiently overcome vessel tortuosity, aneurysmal dead space, and balloon prolapse, allowing for obliteration of large, wide-necked aneurysms.
