Recognizing cerebral hyperperfusion syndrome with intracerebral hemorrhage following carotid artery stenting is critical because the mortality rate is high. This type of hemorrhage usually arises from within several hours to a few days after the procedure. Here we describe a putaminal hemorrhage with extravasation during angiography that developed immediately after carotid artery stenting. A search of the literature revealed only one other similar case report. The etiology of the intracerebral hemorrhage immediately after carotid stenting might be analogous to that of hypertensive hemorrhage.
