Analyzing brain blood clots to understand stroke outcomes

Interest of Molecular Analysis of Cerebral Thrombi in Determining the Prognosis and Etiology of Cerebral Infarction

Observational Assistance Publique Hopitaux De Marseille · NCT05658835

What this trial studies

The MATISSE project investigates how the molecular composition of cerebral thrombi, including metabolites, lipids, and proteins, influences the clinical prognosis of ischemic stroke at three months post-infarction. By collecting and analyzing thrombi during mechanical thrombectomy, the study aims to determine the etiology of the stroke and improve understanding of patient outcomes. This observational study focuses on patients who have undergone endovascular treatment for cerebral infarction, allowing for a detailed examination of the thrombus characteristics.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have experienced a cerebral infarction and received mechanical thrombectomy with thrombus collection.

Not a fit: Patients who have had a cerebral infarction but did not have a thrombus collected during their treatment will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved prognostic assessments and tailored treatments for patients who have suffered an ischemic stroke.

How similar studies have performed: While the specific approach of analyzing cerebral thrombi for prognosis is relatively novel, similar studies have shown promise in understanding stroke mechanisms and outcomes.

Eligibility criteria
