Clinical Trial Summary

In non-acute symptomatic ischemic stroke, the decision-making of medical treatment plus intracranial stenting has been more and more popular, especially in patients with intracranial large severe stenosis or occlusive artery. Nonetheless, there is no evidence from randomized controlled trials evaluating the efficacy of this treatment after the Wingspan Stent System Post Market Surveillance (WEAVE) and Wingspan One Year Vascular Imaging Events and Neurologic Outcomes (WOVEN) trial compared with medical treatment alone. This trial was to investigate whether medical treatment plus intracranial stenting would prevent the recurrent ischemic stroke in the territory of the symptomatic intracranial artery during 1-year follow-up.

Clinical Trial Description

In symptomatic ischemic stroke due to intracranial large severe stenosis or occlusive artery, the choice for treatment has remained controversial after results of the Stenting versus Aggressive Medical Therapy for Intracranial Arterial Stenosis (SAMMPRIS) trial because it demonstrated that the efficacy of medical treatment was superior to intracranial stenting in the low risk of periprocedural stroke or death. However, this conclusion has influenced the role of intracranial stenting in the ischemic stroke treatment and recovery time for a long time because of the unproper patient selection of this trial such as no evidence of medical failure, intracranial stenting earlier than 7 days after the stroke and intracranial stenting in patients with transient ischemic attacks only. Recently, the Food and Drug Administration (FDA) mandated study about intracranial stenting, WEAVE trial, reported not only 97.4% patients with no complication at 72 hours, but also a relatively low 8.5% recurrent stroke and death rate during 1 year in the WOVEN study. In case of the symptomatic stenosis greater than 70%, the probability of recurrent stroke and transient ischemic attack in the territory of the symptomatic stenotic artery in 1 year was 23% and 14%, respectively, despite treatment with antithrombotic therapy and standard management of vascular risk. Given a lot of patients with symptomatic ischemic stroke who have some adjustable indications for intracranial stenting deployment in the world and a paucity of evidence from randomized trials, the purpose of this trial was to compare this treatment versus medical one in the intracranial large severe stenosis or occlusive artery. ;
