Treatment of acute ischemic stroke (AIS) is an evolving field. New treatment options are still needed in order to achieve greater success rates for arterial recanalization. Intra-arterial therapy (lAT) is an option for AIS patients who are not good candidates for intravenous (i.v.) recombinant tissue plasminogen activator (rt-PA) or where it has failed. While good data establishing the role of IAT in AIS management are lacking, the potential clinical efficacy of IAT is based on the premise that recanalization and reperfusion may result in better clinical outcome. Although lAT recanalization and reperfusion rates of large vessel occlusion are much higher than they are for i.v. rt-PA, IAT's radiological efficacy is still far from perfect. Vasodilator use during IAT for AIS may increase the recanalization and reperfusion rates of such therapy. In this report, we describe the radiographic and clinical outcomes in a cohort of AIS patients who received intra-arterial (i.a.) vasodilators during IAT and summarize the role of i.a. vasodilators in the process of recanalization and reperfusion.
