Abstract
|
|
|
|
Symptomatic cerebral air embolism during cerebral angiography is extremely rare. We report on the case of a 69-year-old woman undergoing elective stent-assisted coiling of an unruptured right middle cerebral artery (MCA) bifurcation aneurysm, who was found to have severe attenuation of somatosensory evoked potential (SSEP) and electroencephalography (EEG) during the procedure. Intra-operative DynaCT showed hypodense cortical vessels consistent with cerebral air embolism. Diagnostic and management strategies for this rare complication are reviewed.
