Background: The publication of the MR CLEAN trial in January 2015 changed the face of ischemic stroke care. This was the first study demonstrating a benefit to endovascular treatment of a specific subset of ischemic stroke patients: those with a large vessel occlusion (LVO) presenting within 6 hours of symptom onset. MR CLEAN was followed by a flurry of publications seeking to replicate and refine treatment as well as expand the window for treatment. The REBEL EM team reviewed this literature back in 2018 and, with the help of Dr. Evie Marcolini, created a workflow (shown below).

One major component of LVO management is the use of systemic thrombolytics in patients presenting within the current thrombolytic treatment window prior to endovascular intervention. However, it’s unclear if systemic thrombolytic administration results in better outcomes or if it simply exposes the patient to increased risks at a higher cost. Limited evidence questions the utility of the current approach with lytics + endovascular therapy (Phan 2017, Rai 2018). There is a clear need for further research into systemic thrombolytics dosing and use.

The Novel Coronavirus 2019, was first reported on in Wuhan, China in late December 2019.  The outbreak was declared a public health emergency of international concern in January 2020 and on March 11th, 2020, the outbreak was declared a global pandemic. The spread of this virus is now global with lots of media attention.  The virus has been named SARS-CoV-2 and the disease it causes has become known as coronavirus disease 2019 (COVID-19).  This post will serve as a summary of emerging available evidence in regard to neurologic manifestations associated with COVID-19.

Background Information: The administration of alteplase (tPA) in acute ischemic stroke (AIS) continues to remain a highly debated topic. As hospital systems continue to undergo major changes to facilitate this controversial drug’s administration, more studies are coming out focusing on neuroimaging and how it plays a role in the time window of AIS. The WAKE-UP trial was one of the first studies to identify MRI patterns suggestive of a stroke in patient whose onset time was unknown.1,2 Over the past 10+ years, other studies have also attempted to identify the role of advanced neuroimaging guiding tPA administration for improved functional outcomes. The authors conducted a meta-analysis to test the hypothesis that tPA improves functional outcomes compared with placebo 4.5 - 9 hours after onset in AIS patients who received advanced neuroimaging. Before getting into the study, we need to better understand the terminology and different types of neuroimaging modalities available and how they play a role in strokes.
