Objective: A case that developed unilateral posterior reversible encephalopathy syndrome (PRES) after carotid artery stenting (CAS) is reported.
Case Presentation: The patient was a 79-year-old man who underwent CAS for symptomatic right internal carotid artery stenosis. Left hemiparesis and unilateral spatial neglect appeared on the day after the procedure. MRI presented findings characteristic of PRES although unilaterally. Temporary disruption of the blood–brain barrier due to blood pressure fluctuations in chronic unilateral hypoperfusion caused by stenosis of the right internal carotid artery or toxicity of the contrast medium was suspected.
Conclusion: PRES is considered to be a complication worth attention in CAS.
