Correlation Between Intraoperative Near-infrared Spectroscopy Values and Neurologic Outcomes in Patients Undergoing Total Aortic Arch Replacement Using the Frozen Elephant Trunk Technique.
To correlate intraoperative near-infrared spectroscopy (NIRS) values with neurologic outcomes in patients undergoing total aortic arch replacement using the frozen elephant trunk (FET) technique. ⋯ NIRS is a reliable tool to monitor intraoperative frontal lobe cerebral oxygen saturation. However, its use to predict postoperative stroke remains limited. Further refinements are needed to develop the technique into a prediction tool.
