Cerebral Hyperperfusion Syndrome following Protected Carotid Artery Stenting
Figure 2
Carotid angiogram demonstrating carotid artery stenting (CAS) with distal filter protection in a 77-year-old symptomatic patient. (a) Preprocedural angiogram showing a high-grade stenosis of the left internal carotid artery. (b) After the filter is positioned distal to the lesion the stenosis is predilated with a 3 mm balloon. (c) The self-expanding stent is deployed. (d) Stent after deployment. (e) The stent is postdilated with a 5 mm balloon. (f) The final angiogram shows that the stented site is widely patent. (g), (h) Final angiogram of the intracranial vessels.
