AI Summary
Time is crucial in the treatment of acute ischemic stroke, especially for large vessel occlusion (LVO). Endovascular thrombectomy (EVT) has been proven effective for LVO, but its effectiveness decreases with each 9-minute delay in treatment. Early identification of LVO is vital in order to improve outcomes.
In the treatment of acute ischemic stroke (AIS), time is a key factor in increasing the chance of good outcomes. For large vessel occlusion (LVO), which makes up 15%–30% of all AIS,1 there is clear evidence for the effectiveness of endovascular thrombectomy (EVT). The effectiveness is time dependent so that for every 9-minute delay in treatment, 1 of every 100 patients will have greater disability at 90 days.2 Early identification of patients with LVO is critical in this setting.
