Whether preoperative cerebral small vessel disease and carotid near-occlusion are associated with cerebral hyperperfusion (CH) after carotid endarterectomy has not been reported. This study demonstrated that preoperative Fazekas score ≥ 3, number of lacunes ≥ 2 combined with the presence of carotid near-occlusion can accurately predict CH after carotid endarterectomy. This encourages preoperative MRI scans and suggests we should pay particular attention to patients with CSVD and carotid near-occlusion.
