Acute Carotid Stent Thrombosis (ACST) is a rare complication of Carotid Artery Stenting (CAS) with a potentially fatal outcome. We report a case of ACST occurring five minutes after the end of a successful CAS procedure that was promptly treated by carotid stent-in-stent implantation using a new percutaneous strategy based on the creation of a modified embolic protection device. Following the procedure, we did not observe brain lesions suggestive of acute cerebral ischemic events at the CT scan performed at 48 hours, as well as no neurological deficits in the following days.
