Coil Migration under Stent-Assisted Embolization. A Case Report

Detachable coils are established as a safe and effective treatment option for some patients with intracranial aneurysms. However this treatment is not useful for the treatment of certain types of complicated aneurysms.Wide-necked or broadbased aneurysms are still complicated to embolize because of the risk of coil migration or coil protrusion into the parent vessel. The Neuroform stent has recently been introduced for the treatment of complex aneurysms. The stent functions primarily to provide durable parent vessel protection during embolization. This report demonstrates coil migration occurring as a delayed complication of Neuroform stent-assisedt coil embolization of a small intracranial aneurysm.
