Abstract
Introduction
While acute internal carotid artery (ICA) occlusions are increasingly being treated with carotid angioplasty and stenting (CAS), the utility of CAS in subacute stages is unclear.
Case Report
A 65-year-old patient with an acute left ICA occlusion and pre-existing occlusion on the right side presented with dysarthria and central right-sided facial palsy. Carbon dioxide (CO2) reactivity within the left hemisphere was markedly reduced. Due to acute deterioration despite maximal conservative therapy CAS was performed 8 days after the initial event with an excellent result and symptoms subsided.
Conclusion
CAS in subacute ICA occlusion is possible. Patients should be selected carefully. Assessment of cerebrovascular CO2 reactivity might provide valuable information.
