摘要: Background and Purpose The accuracy of routine ultrasonography in detecting severe carotid artery stenosis was evaluated comparison with cerebral angiography. precision ultrasonographic criteria predicting the risk stroke also assessed. Methods A total 1011 symptomatic bifurcations were studied patients from North American Symptomatic Carotid Endarterectomy Trial (NASCET). Given that all considered for entry into trial, chance a verification bias affecting analyses minimized. data consisted peak systolic velocities frequency changes both internal common arteries. Angiographic calculated as NASCET. Receiver operating characteristic (ROC) curves constructed detection 70% or greater on basis an angiographic assessment. Kaplan-Meier stroke-free survival used to predict stroke. Results a...
