title: De novo basilar artery aneurysm formation after placement of a Wingspan stent.
abstract: Report the de novo formation of an aneurysm after wingspan placement and describe the treatment modality. We report a patient with symptomatic basilar stenosis who underwent placement of a wingspan stent. On 9-month follow-up, the patient was found to have a new 5-mm aneurysm adjacent to the proximal tines of the stent. The patient subsequently underwent placement of an enterprise stent and coils for aneurysm occlusion. We reviewed the literature and discussed possible etiologies for the development of this unique de novo aneurysm.
