Multimodal Imaging Evaluation of Vulnerability of Atherosclerotic Plaques: A Comparison of HR-VWI, OCT, and RWS

The primary objective of this study is to evaluate the vulnerability of intracranial and extracranial atherosclerotic plaques using HR-VWI, OCT, and RWS technologies, while exploring correlations among these three imaging techniques. Secondary objectives include: 1) Investigating the relationship between RWS and plaque progression and identifying optimal RWS predictors; 2) Further evaluating the clinical value of RWS and HR-VWI in stroke prediction through two-year clinical and HR-VWI follow-up evaluations.

High-resolution Magnetic Resonance Vessel Wall Imaging of Plaques

The primary objective of this study is to investigate the predictive value of High-resolution magnetic resonance vessel wall imaging for future stroke occurrence in patients with moderate to severe intracranial and extracranial artery stenosis. The secondary objective is to explore the predictive value of baseline high-resolution magnetic resonance vessel wall imaging for plaque progression.

Standardized Procedure for Intracranial Drug-Eluting Stenting in the Treatment of Intracranial Atherosclerotic Stenosis

The primary objective of this trial is to evaluate the Safety, Efficacy, and Standardized Procedural Optimization of the Intracranial Drug-Eluting Stent System in Patients with Symptomatic Intracranial Atherosclerotic Stenosis.

SeQuent ® Please CIS for the Treatment of INtracranial Atherosclerotic Stenosis

This study is aiming to evaluate the safety and efficacy of SeQuent® Please CIS in the endovascular treatment of symptomatic intracranial atherosclerotic stenosis and restenosis after interventional therapy.

Clinical Trial of Biolimus-coated Intracranial Balloon Dilation Catheter

This test took the target lesion restenosis rate 6 months after the operation as the main endpoint to verify the effectiveness of the intracranial balloon expansion catheter of Biolimus coating. After completing the follow-up 6 months after the operation, a clinical summary report was issued for the registration application of the product, and on this basis, 12 months of postoperative follow-up was carried out to evaluate the mid-term curative effect.
