Intravenous (IV) recombinant tissue plasminogen activator is the standard of care for patients with acute ischemic stroke (AIS) who present to the hospital within 4.5 hours of symptom onset. However, IV thrombolysis, even bridging thrombolysis (combining intravenous thrombolysis and mechanical thrombectomy) has limited efficacy among patients who had occlusive lesions associated with highgrade arterial stenosis requiring revascularization to improve neurological deficits. The investigators evaluated whether rescue stenting results in good outcomes among patients after the failure of intravenous thrombolysis and bridging thrombolysis.
