To evaluate the possible role of intraoperative cerebral emboli in the origin of perioperative stroke during major head and neck surgical procedures. ⋯ No intraoperative cerebral emboli were noted by using TCD ultrasound for embolus monitoring in patients undergoing major head and neck surgery involving carotid sheath manipulation. This detection system is easily used in appropriate head and neck cases and allows real-time, noninvasive intraoperative monitoring.
