Thrombus Composition in Cerebral Infarctions: Study of Its Association With Plasma Biomarkers, Treatment Efficacy, Etiology and Prognosis.

Sponsor: François Delvoye

Summary

This study focuses on thrombi collected during mechanical thrombectomy procedures, as well as on plasma biomarkers analyzed concomitantly. The primary objective of the study is to investigate associations and correlations between, on the one hand, the composition of thrombi retrieved during thrombectomy and, on the other hand, plasma biomarkers, treatment response, etiology, and prognosis of ischemic stroke and cerebral venous thrombosis. The secondary objectives of this study are to precisely characterize the biochemical composition of the thrombi (notably using techniques such as enzyme-linked immunosorbent assay \[ELISA\] following extraction of proteins contained within the thrombus), their histological structure (using standard histology with hematoxylin-eosin staining and immunohistochemistry), and their biological activity (in particular through in vitro assays assessing resistance to thrombolysis and the endothelial-adhesive or destructive properties of thrombi). Additional secondary objectives include testing new therapeutic methods for the lysis of thrombi collected by mechanical thrombectomy and establishing a link between thrombus transcriptomics and their confirmed etiology, particularly for thrombi initially described as having an embolic appearance and of undetermined etiology.
