Interventionnal Study to investigate the accuracy of our clinical based algorithm performed by using a visioconference device to assess the eligibility of acute recanalisation treatment (intraveinous thrombolysis (IVT) and/or mechanical thrombectomie (TM). Clinical identification of type of treatment is needed is pre-hospital triage of these patients.
The outcome of ischemic stroke (IS) with large artery occlusion (LVO) is related to the volume of infarcted brain witch is related to the delay of arterial recanalisation. IVT is available in multiple stroke units in France but, in case of LVO, the association with TM is needed. The availability of endovascular capable centers is limited to tertiary care hospitals. As a result, pre-hospital identification of these patients is a priority and the optimization of the triage can be done by a clinical algorithm carried out by a neurological tele-evaluation. OPTIC-AVC is a multi-phase study. This phase is about the evaluation of accuracy of our algorithm performed by a quick and standardized neurological tele-evaluation to predict the eligibility for recanalisation treatment (IVT and/or TM) of patients suspected of acute stroke in the emergency setting. The effective therapeutic decision for each patient, performed by another neurologist, will be blind to the theoretical therapeutic decision resulting from the algorithm. Theoretical and effective therapeutic decision will be compared a posteriori

NONE
Enrollment
215
Standard neurological tele-evaluation (limited to 15minutes) remotely carried out by a first neurologist via a tablet (DVCM) and an operator. A second neurologist assist at the assessment without intervention next to the patient. Once the remote assessment is complet, the second neurologist ensure the continuation of standard patient care.
