Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients admitted with acute ischemic stroke confirmed by MRI, specifically those with vertebrobasilar artery occlusion.

Probably not a fit

Patients who cannot undergo MRI due to contraindications will not benefit from this study.

What this trial studies

This observational study evaluates the effectiveness of preoperative magnetic resonance imaging (MRI) in selecting patients with posterior circulation ischemic stroke who are likely to benefit from mechanical thrombectomy. It focuses on the pons-midbrain-medulla index (PMMI) to assess the degree of ischemia and correlate it with clinical outcomes 90 days post-surgery. By analyzing MRI images, the study aims to improve patient selection for endovascular thrombectomy, potentially leading to better recovery outcomes. The study is conducted as a multicenter, prospective cohort analysis involving several hospitals in Tianjin.

Why it matters

Potential benefit: If successful, this study could enhance patient selection for mechanical thrombectomy, leading to improved clinical outcomes for those with posterior circulation ischemic strokes.

How similar studies have gone: Previous studies have indicated that MRI can lead to better clinical outcomes compared to CT in similar patient populations, suggesting a promising approach.
