Background: Despite accumulated experience and improved understanding of the tools, endovascular treatment of cerebral aneurysms still has risks associated with the technique itself and with the specificity of the pathology treated. An important risk is parent vessel Guglielmi detachable coil herniation. Here we review and illustrate our experiences in using a stent to manage this complication.
Methods: We reviewed our experiences in 142 intracranial aneurysm embolizations over a four and a half year period and identified 13 cases with intravascular stent deployment. Three cases were unique in using a stent for salvage of coil herniation into the parent vessel.
Results: We reported these cases and reviewed the literature for the management of parent vessel coil herniation.
Conclusion: Parent vessel coil herniation was an uncommon but important complication of endovascular coiling of intracranial aneurysm. Intravascular stent placement provided a tool to sequester herniated coils from the lumen of the parent artery to minimize thromboembolic complications and restore flow.
