The effectiveness of acute ischemic stroke (AIS) management has improved considerably in recent years with thrombolysis and more recently with mechanical thrombectomy (MT). Currently, mechanical thrombectomy can only be performed in stroke unit with an interventional neuroradiology center by experienced/qualified interventional neuroradiologists. In the Rhone area, only one hospital has the authorization to perform mechanical thrombectomy. Therefore, transferring directly eligible acute ischemic stroke patients for mechanical thrombectomy to this center constitutes an important stake of the triage of suspected acute ischemic stroke patients. Some validated scores for the identification of severe strokes and large vessel occlusion, including the Cincinnati prehospital stroke severity scale (CPSSS), appear to be relevant for pre-hospital use in order to identify patients potentially eligible for mechanical thrombectomy and address them to a stoke unit with interventional radiology center.
- Questionnaire Diagnostic Test
Intervention Desc: Tests from Cincinnati prehospital stroke severity scale (CPSSS) will be carried out by the physician at emergency medical services on telephone call with firemen, paramedics or the emergency medical services team for any stroke suspicion that meets the criteria for inclusion. Emergency department physician will have to follow a standardized questionnaire to complete the different items of the score. The score will not be calculated by emergency department physician and will not influence the orientation and management of patients. The final diagnosis will be the presence or absence of a large vessel occlusion. This diagnosis will be done on cerebral imaging by a neurologist. ARM 1: Kind: Experimental Label: Patients with suspected ischemic stroke Description: The cohort will be constituted of patients treated for a stroke suspicion after calling emergency medical services of the Rhone and presenting a symptom-onset (the last time the patient was seen without deficit) less than 6 hours.
