Caption: *Estimation of the percentage reduction in vessel diameter caused by plaques seen in Doppler VPSM: Maximum peak systolic velocity; SVI: Systolic Velocity Index, obtained by dividing the peak systolic velocity in the internal carotid artery by the peak systolic velocity in the common carotid artery. PSV: Peak Systolic Velocity; ICA: Internal Carotid Artery; CCA: Common Carotid Artery.
Note: In patients undergoing CEA with intraoperative videoangiography with fluorescein (March 2021 to July 2023) - Belo Horizonte, MG, Brazil.
