Not applicable Interventional Hopital Foch · NCT05595876

This study is testing which of two techniques for removing blood clots, stent retriever or contact aspiration, works better for people having an acute stroke with a specific type of blockage.

What this trial studies

This clinical trial investigates the effectiveness of two techniques, stent retriever thrombectomy and contact aspiration thrombectomy, in patients with acute stroke who exhibit a specific clinico-neuroradiological mismatch pattern. The study aims to determine which method leads to better recanalization outcomes and overall clinical prognosis. Patients eligible for the trial must have a certain type of occlusion in the middle cerebral artery and meet specific imaging criteria. Statistical analyses will be conducted by the Biostatistics Department of the University of Lille to ensure robust evaluation of the results.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with M1-Middle Cerebral Artery occlusions who are eligible for mechanical thrombectomy.

Not a fit: Patients with isolated M2 occlusions or severe comorbidities that would prevent improvement are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve treatment outcomes for patients suffering from acute strokes by identifying the most effective thrombectomy technique.

How similar studies have performed: Previous studies, such as the ASTER Trial, have shown comparable results between stent-retrievers and contact aspiration, indicating that this approach is grounded in existing research.
