Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate the hypothesis that an ultra-fast triage with one-stop in angiography suite based on cone-beam CT compared to traditional protocol offers a better outcome in the distribution of the modified Rankin Scale scores at 90 days in acute ischemic stroke patients with suspected large vessel occlusion (LVO) within 6 hours from symptoms onset.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type ACTIVE_COMPARATOR

Direct Transfer to Angio Suite

Intervention Type OTHER

Patient will be direct transferred to angiography suite where EVT team will be waiting for it.

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.
