3D-fusion-imaging-assisted carotid artery stenting is safe and feasible.

Background: Renal insufficiency and allergy to iodine contrast are relative contraindications to carotid artery stenting (CAS). The primary aim of this pilot study was to evaluate the feasibility and safety of the CAS assisted by 3D fusion of previously performed computed tomography (CTA) and magnetic resonance angiography (MRA) images and DynaCT, the secondary aim was to determine if 3D fusion decreases radiation exposure and the amount of contrast needed during the procedure.

Methods: Retrospective review of patients who underwent CAS between October 1st, 2012 and November 30th, 2014 was performed.
