|Condition or disease||Intervention/treatment||Phase|
|Stroke, Acute||Other: Direct Transfer to Angio Suite||Not Applicable|
Prospective, randomized, open, treatment-blinded trial of acute stroke patients with suspected large vessel occlusion within 6 hours from symptoms onset in which two strategies will be compared: Direct Transfer to Angiography Suite (DTAS) vs. Computed Tomography Suite (DTCT). The study will be unicentric however there is the possibility of incorporating new stroke centers with previous experience of at least 50 DTAS cases.
The RACE scale (Rapid Arterial oCclusion Evaluation) will be used as a prehospital screening tool to identify acute stroke patients with suspicion of LVO. Once prenotifying the imminent arrival and the verified inclusion and exclusion criteria by the Neurologist at arrival, the patient will be randomized by an app in one of both study protocols.
Subjects will be followed up to 90 days post-randomization.

Active Comparator: Direct Transfer to Angio Suite
After a fast neurological evaluation, patient will be direct transferred to angiography suite where endovascular treatment (EVT) team will be waiting for it. It will be done a cone beam-CT and if the image don't contraindicate endovascular treatment it will be performed and the large vessel occlusion will be confirmed by arteriography. If intravenous treatment have not been previously administered, it will be able to start in parallel.
Other: Direct Transfer to Angio Suite
Patient will be direct transferred to angiography suite where EVT team will be waiting for it.
No Intervention: Direct Transfer to CT Scan
After a fast neurological evaluation, patient will be transferred to CT suite where usual image protocol will be performed (CT and CT-angio). Within 6 hours from onset CT perfusion could be required to take detections. Once interpreted image results, it will be decided intravenous and/or endovascular treatment.
- Clinical outcome measurde by modified Rankin Scale score (shift analysis) [ Time Frame: 90 days ]
Modified Rankin Scale score in ischemic stroke patients with large vessel occlusion as evaluated through a structured telephone-based interview performed by a central assessor who is blinded to group assignment.
Modified Rankin Scale measures functional status with a range from 0 (asymptomatic) to 6 (dead).
- Rate of patients with treatment associated complications. [ Time Frame: 72 hours ]Lack of treatment associated complications, mainly hemorrhagic transformation.
- Delay of inhospital times [ Time Frame: 8 hours ]Time from door to groin puncture
- Rate of dramatic improvement [ Time Frame: 24 hours ]10 NIHSS points drop or NIHSS <2
- Rate of good functional outcome [ Time Frame: 90 days ]Modified Rankin Scale score ≤2
- Rate of patients treated by endovascular treatment [ Time Frame: 8 hours ]
