Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with acute ischemic stroke in the posterior circulation and a National Institutes of Health Stroke Scale (NIHSS) score of 4 or higher.

Probably not a fit

Patients with intracerebral hemorrhage, severe respiratory instability, or those who are intubated prior to randomization may not benefit from this study.

What this trial studies

This clinical trial aims to determine the feasibility of using procedural sedation compared to general anesthesia for patients undergoing endovascular treatment for vertebrobasilar stroke. The study will involve a prospective randomized design with a parallel-group approach, where patients will be assigned to either sedation or general anesthesia during their procedure. The goal is to gather high-level evidence on the impact of anesthetic modality on functional outcomes in this specific patient population, which has been under-researched compared to anterior circulation strokes.

Why it matters

Potential benefit: If successful, this study could lead to less burdensome sedation methods for patients undergoing endovascular treatment, potentially improving recovery outcomes.

How similar studies have gone: While some retrospective studies and a small single-center trial have suggested that procedural sedation may be feasible, this study aims to provide more robust evidence in a prospective randomized format.

Inclusion Criteria:

1. Decision for thrombectomy according to local protocol for acute recanalizing stroke treatment
2. Age 18 years or older, either sex
