RT Journal Article SR Electronic T1 Hyperacute Intracerebral Hemorrhage Complicating Carotid Stenting Should Be Distinguished from Hyperperfusion Syndrome JF American Journal of Neuroradiology JO Am.

In the few similar cases published there were no prodromata, but hyperacute onset of severe neurologic deterioration corresponding to intracerebral hemorrhage (ICH). Our findings suggest that besides the delayed ICH that is associated with hyperperfusion syndrome (HPS), a second type of hyperacute and usually fatal ICH exists that resembles hypertensive hemorrhage.
