Hyperacute Carotid Stent Thrombosis During Emergent Revascularization Treated with Intraarterial Eptifibatide After Systemic Administration of Recombinant Tissue Plasminogen Activator

Abstract

A 57-year-old woman with National Institutes of Health Stroke Scale (NIHSS) score of 26 was found to
have an acute left carotid occlusion with tandem left M1 thrombus within 1.5 hours of symptom onset.
After no neurologic improvement following standard-dose intravenous (IV) recombinant tissue plasminogen activator (rtPA), emergent neuroendovascular revascularization with carotid stenting and intracranial
thrombectomy were performed under conscious sedation. Thrombolysis in myocardial infarction (TIMI)-3
flow restoration and symptom resolution were achieved postprocedure; however, complete carotid stent
thrombosis was noted on final angiographic runs (25 minutes later), correlating with neurologic decline.
Rapid administration of an intraarterial (IA) bolus dose of eptifibatide resulted in TIMI-3 flow restoration,
with neurologic improvement. The patient was discharged three days postrevascularization on dual antiplatelet therapy with an NIHSS score of 1. Intraarterial (IA) eptifibatide can be an effective option for acute
stent occlusion during emergent neuroendovascular revascularization after IV rtPA administration.
