Cerebral thrombosis

Cerebral thrombus formation occurs after development of infarcts following tMCAO. (Göb et al. 2021)

Cerebral thrombosis is not causative for secondary infarct growth during ischemic stroke

Here, we combine the model of transient middle cerebral artery occlusion (tMCAO) with light sheet fluorescence microscopy and immunohistochemistry of brain slices to investigate the kinetics of thrombus formation and infarct progression. Our data reveal that tissue damage already peaks after 8 h of reperfusion following 60 min MCAO, while cerebral thrombi are only observed at later time points.
