Association between changes in intracranial blood flow and higher brain function before and after carotid endarterectomy - Association between changes in intracranial blood flow and higher brain function before and after carotid endarterectomy

Significant improvement in postoperative MMSE score was observed at 6 months in all patients and at 3 and 6 months in the mild cognitive impairment group (group M). SPECT and NIRS showed no significant changes. Preoperative factors affecting MMSE score improvement from preoperative to 6 months were examined: in Group M, multivariate analysis in the backward selection method revealed statistically significant differences in preoperative MMSE score and preoperative frontal centroid and slope.
