Revascularization of acute stent thrombosis after carotid artery stenting in a CYP2C19*2 heterozygote patient.

Carotid artery stenting (CAS) is an alternative strategy to carotid endarterectomy for the prevention of ischemic stroke. Acute carotid stent thrombosis (ACST) is an extremely rare but devastating complication of CAS. Although cases of successful recanalization have been reported, there is still a lack of experience regarding the choice of ACST treatment methods and the timing of such treatments, especially when patients are confirmed CYP2C19*2 heterozygotes. Here, we report a case of successful revascularization after ACST in a patient with CYP2C19*2 heterozygosity. We also review the literature and discuss appropriate treatment strategies for this devastating and rare event.
