Ultrasound Evaluation of Carotid Artery Atherosclerotic Plaques and Recanalization

Summary

The purpose of this multiple-center study are: 1) To establish the ultrasound criteria for evaluating vulnerable plaques by comparing the plaque echo characteristics before CEA (carotid artery endarterectomy) and plaque specimen after CEA.

2\) To establish the carotid artery recanalization strategies based on the evaluation results of carotid artery and intracranial artery by color doppler flow imaging and TCCS/TCD (transcranial color coded sonography/transcranial doppler).

3\) To compare the success rate and the incidence of restenosis between CEA and carotid artery stenting.
