Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To investigate the efficacy and safety of carotid stenting for vulnerable carotid plaques. All patients with carotid artery stenosis underwent carotid arterial contrast-enhanced ultrasonography before operation. According to the examination results, they were divided into two groups: vulnerable plaque group and stable plaque group. The incidence of perioperative stroke events in the two groups was compared. The incidence of stroke events in the two groups within 1 year was compared.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

1. To enroll 100 cases of patients suffering from carotid artery stenosis。the investigators perform contrast enhanced ultrasound on patients for identifying the vulnerable plagues
2. The investigators divide patients into the stable group and the vulnerable group based on the results of CEUS inspection.
3. All patients undergo carotid stent. To analysis the incidence of postoperative complications such as stroke and mortality within 30 days and to compare the differences between the two groups.
