Intraoperative transcranial Doppler ultrasound in head and neck surgery: a preliminary report.
PURPOSE: To evaluate the possible role of intraoperative cerebral emboli in the origin of perioperative stroke during major head and neck surgical procedures. MATERIALS AND METHODS: Eleven patients undergoing major head and neck surgery that involved direct manipulation of the carotid sheath were the participants in this study. Transcranial Doppler (TCD) ultrasound was used intraoperatively to detect possible cerebral emboli. The presence or absence of intraoperative cerebral emboli in each patient was assessed by the presence or absence of typical embolic signal patterns within the TCD waveform. RESULTS: No intraoperative cerebral emboli were noted in the series, nor did any patient have a postoperative stroke. CONCLUSIONS: 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.

Stenting of symptomatic stenosis of the intracranial internal carotid artery.
Percutaneous balloon angioplasty has been reported to be useful in the treatment of intracranial atherosclerotic arterial stenoses; however, arterial dissection with increased risk of stroke has limited its widespread implementation. Although vascular stenting has improved the outcome of similar procedures in the extracranial vasculature, its intracranial application has been limited by the lack of suitable stents. We report a case of successful percutaneous stenting of a symptomatic intracranial carotid artery using a second-generation, flexible, coronary stent.
