NCT03786666

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • The rate of combination endpoints events including death, cerebral hemorrhage , newly cerebral infarction, hyperperfusion syndrome,and residual sternosis≥50%.

    The rate of combination endpoints events, including death, cerebral hemorrhage , newly cerebral infarction, hyperperfusion syndrome, and residual sternosis≥50%

    within 30-day after recanalization.

Secondary Outcomes (1)

  • the rate of re-current cerebral artery events and the occurence of restenosis

    during the at least 1 year follow-up period

Sampling MethodNon-Probability Sample
Study Population

Patients with carotid artery moderate (50-69%), severe (70-99%) stenosis or occlusion, who needs recanalization by CEA or stenting.

You may qualify if:

  • \) Patients with carotid artery moderate (50-69%, with symptoms), severe (70-99%, with or without symptoms) stenosis or occlusion diagnosed by CDFI and confirmed by CTA or DSA.
  • \) Patient has the indications for carotid artery stenting or CEA according to the guidelines published by the Stroke Prevention Engineering Committee, the National Health Commission of China.
  • \) Patient with complete imaging evaluation and can be followed up to at least 1 year.

You may not qualify if:

  • \- 1) Patients with non-atherosclerotic carotid artery stenosis or occlusion, such as dissection, aneurysm, arteritis, cardiac embolism and et al.
  • \) Patients with cerebral hemorrhage. 3) Pregnant
