Bidirectional Transradial and Transfemoral Approach for Stent-Assisted Coil Embolization of Right Subclavian Artery Saccular Aneurysm.

Subclavian artery aneurysms are rare lesions that usually require treatment for complications. Bidirectional stent-assisted coil embolization is the most effective treatment of complex wide-necked aneurysms. The stents provide a rigid scaffold that allows coil deposition with reduced risk of coil herniation into the parent vessel lumen. Bidirectional transradial and transfemoral approaches contribute to stable procedure. We report a successful bidirectional stent-assisted coil embolization of a saccular aneurysm of the subclavian artery as an alternative to stent graft implantation to diminish the risk of right vertebral artery occlusion.
