Coil Embolization Assisted by Balloon-expandable Stent for Vertebral Broad Neck Aneurysm

Abstract

We performed coil embolizations assisted by balloon-expandable stent for vertebral aneurysms in 7 patients. None of the patients were indicated for parent artery occlusion, due to aplasia or hypoplasia of the contralateral vertebral artery, or for other anatomical reasons. Five aneurysms were successfully embolized, although 2 patients died of rebleeding or ischemic complication. We offer tips and discuss pitfalls of coil embolization assisted by balloon-expandable stent.
