Neuropsychological performance one week after carotid endarterectomy reflects intra-operative ischemia

Abstract

Fourteen patients with severe bilateral carotid artery stenosis underwent carotid endarterectomy. Intra -operative ischemia was monitored by somatosensory evoked potentials (SSEP) bilaterally. Neuropsychological evaluations were completed within two days before operation and 4-9 days after operation. Complete loss of Nl-Pl or P1-N2 components of the SSEP (seen in 4 patients) was associated with a worsening of n euro psychological abilities (p
