[Prehospital Stroke Rescue and Acute Stroke Care:Focusing on Acute Large Vessel Occlusion]

The implementation of standardized prehospital stroke assessments, transport decision-making, and treatment is crucial for optimizing acute stroke care. This includes the efficient utilization of intravenous thrombolysis for acute ischemic stroke and mechanical thrombectomy for acute large-vessel occlusion (LVO). In the existing acute stroke care system, it is imperative to promptly recognize a stroke, gather essential information, select an appropriate hospital with the necessary capabilities, and establish a rapid transport pathway. The Japan Stroke Association has designated primary stroke centers for intravenous thrombolysis and mechanical thrombectomy, making this information accessible to both the general public and healthcare professionals. Additionally, the JSS/JAAM standard LVO Scale, comprising six items, could be the preferred scale for predicting LVO in Japan, with efforts underway to address various challenges associated with its clinical application.
