Carotid artery stenting for acute ischemic stroke patients after intravenous recombinant tissue plasminogen activator treatment

Abstract

We herein report three ischemic stroke patients who underwent emergency carotid artery stenting after receiving intravenous tissue plasminogen activator (t-PA) treatment. All patients received antiplatelet medications immediately before stent placement for loading as well as dual antiplatelet therapy after stenting. Under high-dose and dual antiplatelet therapy, none of the three patients showed symptomatic intracranial hemorrhaging. However, one case showed reocclusion of the placed stent after acute thrombosis. As a result, new treatment strategies for the use of antiplatelet agents during emergency stent placement must be developed, particularly for patients who have received intravenous t-PA therapy.
