Abstract

Objective: We report a case of right hemisphere hypoperfusion following right carotid artery stenting (CAS).<br>Case presentation: A 72-year-old man presented with severe asymptomatic stenosis in the right internal carotid artery. CAS was performed for stenosis of the right internal carotid artery using a distal filter and open cell stent. However, he experienced left hemispatial neglect, left hemianopsia, and left hemiparesis 13 hours after the CAS procedure. Angiography revealed diffuse vasospasm occurring primarily in the distal portion of the right middle cerebral artery. Perfusion CT images indicated hypoperfusion in the ipsilateral hemisphere. These findings were temporary, and the patient was discharged without any neurological deficits.<br>Conclusion: These results suggest that reversible cerebral vasoconstriction can occur after CAS, resulting in transient ischemic complications.
