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....Read More
