Analyzing blood clots in stroke patients to improve treatment outcomes

Thrombus Composition in Ischemic Stroke: Analysis of the Correlation With Plasma Biomarkers, Efficacy of Treatment, Etiology and Prognosis

Observational Fondation Ophtalmologique Adolphe de Rothschild · NCT03268668

This study looks at the blood clots from stroke patients who had a procedure to remove them to see if understanding their makeup can help improve treatment and outcomes.

What this trial studies

This observational study focuses on patients who have experienced an ischemic stroke and have undergone thrombectomy, a procedure to remove blood clots. It aims to collect and analyze the composition of the thrombus along with plasma biomarkers to understand their correlation with stroke etiology and prognosis. By examining the characteristics of the clots retrieved during treatment, the study seeks to identify patterns that could inform better management strategies for acute strokes. The findings may help clarify the relationship between thrombus composition and patient outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have suffered a cerebral infarction due to arterial occlusion and have undergone thrombectomy.

Not a fit: Patients who are pregnant, breastfeeding, or under legal protection measures will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment protocols for stroke patients based on the specific characteristics of their blood clots.

How similar studies have performed: Previous studies have shown varying results regarding thrombus composition and stroke etiology, indicating that this area of research is still evolving and may yield novel insights.
