Endovascular Treatment of 2 Synchronous Extracranial Carotid Artery Aneurysms Using Stent-Assisted Coil Embolization and Double Bare-Metal Stenting

Abstract

Extracranial carotid artery aneurysms located in the cervical region in close proximity to the skull are difficult to access using open surgical methods. Endovascular treatment has emerged as an alternative option for anatomically challenging internal carotid artery aneurysms. However, data comparing various endovascular techniques including stent grafting, coil embolization, double stenting, and stent-assisted coil embolization are lacking, making it difficult to determine the optimal treatment. We present a case of a patient with 2 fusiform extracranial carotid artery aneurysms treated successfully with a combination of double stenting and stent-assisted coil embolization. We also discuss technical considerations for selecting the appropriate endovascular intervention.
