Abstract
INTRODUCTION: Wake-up strokes are challenging to manage due to unknown time of onset. Recently, the wake-up trial demonstrated that recombinant tissue plasminogen activator (rtPA) could be administered based on the magnetic resonance imaging (MRI)- diffusion weighted imaging/fluid attenuated inversion recovery mismatch. Many still doubt the safety results due to the higher rate of hemorrhagic conversion reported. Although it was statistically insignificant, the study was terminated early. Furthermore, Corona virus disease-19 is associated with coagulopathy and a higher risk of hemorrhagic conversion. CASE REPORT: A 46-year-old fully functioning male presented with a wake-up right hemiparesis, right facial droop, and expressive aphasia. His National Institute of Health Stroke Scale was 4 upon arrival. Last known well state was >4.5 hours. He tested positive for SARS-CoV-2 viral infection. He had left distal-M2 occlusion. He was deemed not a candidate for rtPA. Hyperacute-MRI protocol showed diffusion weighted imaging/fluid attenuated inversion recovery mismatch. The patient received rtPA at 6.5 hours from the last knwn well state. Follow-up MRI-susceptibility weighted imaging revealed fragmented clot. The stroke burden was less than that shown on the initial computed tomography-perfusion scans implying saved penumbra. There was no hemorrhagic conversion despite low fibrinogen levels. CONCLUSION: The hyperacute-MRI protocol for wake-up COVID-19 associated strokes might be a safe option.
