ABSTRACT
Objective To investigate the value of magnetic resonance imaging (MRI)-based intravenous thrombolysis in patients with wake-up ischemic strokes (WUIS).Methods Patients presenting within 12 hours of acute stroke symptom onset and those with WUIS confirmed by CT,excluding intracranial hemorrhage,were encouraged to perform an emergent brain MRI scan to confirm the diagnosis of hyperacute ischemic stroke (hyper-intense in DWI without hyper-intense change in T2WI or fluid attenuated inversion recovery (FLAIR)).These patients then received intravenous thrombolytic therapy with recombinant tissue plasminogen activator (rt-PA).All patients were divided into either stroke presenting within 12 hours or WUIS.The clinical outcomes were assessed by the modified Rankin scale (mRS) and the Barthal index (BI) at baseline and at 90 days after the thrombolysis therapy.Results Two hundred and sixty-one patients (261/563,56.4%) had confirmed diagnosis of hyperacute ischemic stroke (WUIS,n =73,73/121 =60.3% vs within 12 hours,n =188,188/342 =55.0%).Altogether,192 patients (139 in within 12 hours group,and 53 in WUIS group) received intravenous thrombolytic therapy with rt-PA.No significant differences were found between the 2 groups at the baseline characteristics and at 90 days outcomes after the thrombolysis therapy(x2 =1.296 and 1.473,P =0.538 and 0.489,respectively).Also no significant differences were found in the incidence rate of secondary hemorrhage (including both of asymptomatic and symptomatic) and mortality rate between the 2 groups.Conclusion MRI-based intravenous thrombolysis is safe and effective in the treatment of patients with hyperacute WUIS.
