Ischemic stroke


This minimally invasive model of cerebral ischemia-reperfusion is based on an endovascular transient occlusion and recanalization of the middle cerebral artery.

The model allows per-occlusion and immediate post-recanalization imaging, enables evaluation of the ischemic penumbra, target of neuroprotection intervention, in addition to acute and chronic neurofunctional assessments.
