Abstract:
Carotid endarterectomy (CEA) can effectively treat symptomatic carotid stenosis, however, perioperative stroke is the most important complication of CEA. The microemboli generated before and after the operation are the most important reason for causing perioperative stroke. In addition, the hypoperfusion and postoperative hyperperfusion syndrome caused by intraoperative clipping of carotid artery, as well as carotid restenosis or occlusion after CEA are all the causes of perioperative stroke. As a non-invasive, real-time monitoring tool, transcranial Doppler (TCD) can be widely used in intraoperative monitoring of CEA, It is able to detect a variety of perioperative blood flow changes and the production of microemboli, and thus effectively predicts the occurrence of perioperative stroke, and decreases the risks of perioperative stroke.
