Evaluation of Direct Transfer to Angiography Suite vs. Computed Tomography Suite in Endovascular Treatment: Randomized Clinical Trial (ANGIOCAT)
- Conditions
- Stroke, Acute
- Interventions
- Other: Direct Transfer to Angio Suite
- Registration Number
- NCT04001738
- Lead Sponsor
- Hospital Vall d'Hebron
- Brief Summary
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
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.

Group Intervention Description Direct Transfer to Angio Suite 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.
- Primary Outcome Measures
Name Time Method Clinical outcome measurde by modified Rankin Scale score (shift analysis) 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. 72 hours Lack of treatment associated complications, mainly hemorrhagic transformation.
- Secondary Outcome Measures
Name Time Method Rate of good functional outcome 90 days Modified Rankin Scale score ≤2
Rate of patients treated by endovascular treatment 8 hours Delay of inhospital times 8 hours Time from door to groin puncture
Rate of dramatic improvement 24 hours 10 NIHSS points drop or NIHSS \<2
