Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are patients who have experienced an acute ischemic stroke within the last 24 hours and have specific imaging results indicating an extra-large infarct core.

Probably not a fit

Patients with evidence of hemorrhage, severe comorbid conditions, or those who are pregnant may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to collect data on the outcomes of endovascular thrombectomy in patients suffering from acute ischemic stroke with extra-large infarct cores, defined as having a volume greater than 100ml. It builds on previous randomized trials that have demonstrated the efficacy of thrombectomy in patients with large vessel occlusion. The study will enroll patients within 24 hours of stroke onset and will assess their eligibility based on specific imaging criteria. The goal is to better understand the safety and effectiveness of this intervention in a population that has been underrepresented in prior studies.

Why it matters

Potential benefit: If successful, this study could provide critical insights into the treatment of patients with extra-large ischemic strokes, potentially improving their functional outcomes.

How similar studies have gone: Previous studies have shown success with endovascular thrombectomy in large infarct patients, but this specific focus on extra-large infarct cores is relatively novel.
