Abstract

Near-infrared spectroscopy (NIRS) enables continuous and non-invasive monitoring of regional cerebral oxygen saturation (rSO2) during carotid endarterectomy. In this article, we report two cases of patients who underwent internal carotid endarterectomy with rSO2 monitoring throughout the surgery. The study determined the patients' baseline rSO2 and evaluated changes in regional cerebral oxygen saturation at different times during the surgery, which allowed the detection and management of instances where patients experienced rSO2 drops. Both patients in the study experienced a decrease in rSO2 during carotid artery clamping, necessitating intervention to adjust cerebral perfusion through blood pressure parameter adjustments and one patient needed to create a temporary shunt while waiting for reperfusion. Early detection of cerebral ischemia during surgery through continuous rSO2 monitoring allows for timely intervention, potentially reducing the rate of complications during and after carotid endarterectomy.
