Values are presented as mean±standard deviation or number (%).

ICA, internal carotid artery; rSO₂, regional oxygen saturation; Post/Pre (%), the ratio of post- to pre-clamp rSO₂ level representing changes in the degree of cerebral perfusion after ICA clamping; Post/End (%), the ratio of pre-clamp to post-declamp rSO₂ level representing changes in the degree of cerebral perfusion after endarterectomy.
