OBJECTIVE: Most acute ischemic stroke (AIS) patients with unwitnessed symptom onset are ineligible for intravenous thrombolysis due to timing alone. Lesion evolution on FLAIR MRI correlates with stroke duration, and quantitative mismatch of diffusion-weighted MRI (DWI) with FLAIR (qDFM) might indicate stroke duration within guideline-recommended thrombolysis. We tested if intravenous thrombolysis ≤4.5 h from time of symptom discovery is safe in patients with qDFM in an open-label, phase 2a, prospective study (NCT01282242)...
