Abstract:
Objective To assess the effectiveness of cerebral hemodynamical changes after carotid endarterectomy (CEA).Methods Eleven patients with symptomatic internal carotid arterial stenosis were selected.Before and after CEA,the peak systolic velocity,blood flow volume in ipsilateral internal carotid artery and the peak systolic velocity in bilateral cerebral middle artery were measured by color Doppler flow imaging (CDFI) and transcranial Doppler (TCD).Also collateral circulations via the circle of Willis and the ophthalmic artery were detected.Results After operation,the systolic peak velocity in the ispilateal internal carotid arteries decreased [( 291.70 ? 65.2 5)cm/s vs ( 100.85 ? 35.68 ) cm/s,P
