Beschreibung
Inclusion Criteria:
- Aged between 18 and 80 years (inclusive), with no gender restriction.
- Imaging diagnosis indicates symptomatic carotid artery stenosis (by NASCET method) ≥50% or asymptomatic carotid artery stenosis (by NASCET method) ≥70%.
- Suitable for carotid artery stenting.
- Good compliance, voluntarily signed the informed consent form, and able to follow up as required.
Exclusion Criteria:
- Severe tortuosity or calcification of the diseased vessel, preventing device delivery.
- Patients with ipsilateral external carotid artery occlusion or severe stenosis of the intracranial segment of the internal carotid artery.
- Patients with contralateral common carotid artery occlusion or severe stenosis or occlusion of the internal carotid artery.
- Patients with severe stenosis or occlusion of the vertebrobasilar artery (excluding non-dominant vertebral artery).
- Spontaneous intracranial hemorrhage, massive cerebral infarction, progressive stroke, or myocardial infarction within the past 3 months.
- Presence of substantial acute or subacute thrombus adjacent to the lesion.
- mRS > 3.
- Patients with a clear risk of cardioembolism, such as atrial fibrillation, or those with definite indications for anticoagulation.
- Chronic obstructive pulmonary disease requiring long-term continuous oxygen therapy.
- Patients with prior stent treatment in the ipsilateral head and neck vessels.
- Patients with end-stage renal failure requiring dialysis.
- Life expectancy less than 6 months.
- Patients unsuitable for magnetic resonance imaging (MRI) for any reason.
- Patients with absolute or relative contraindications to antiplatelet therapy.
- Inability to cooperate with the study due to dementia or mental disorder.

Intervention / BehandlungIntervention / Behandlung |
|---|---|
|
Experimental: Combined Cerebral Protection (BGC + Filter + intermediate catheter)
Participants in this arm will undergo carotid artery stenting (CAS) with a multimodal cerebral embolic protection strategy, incorporating proximal balloon occlusion via a Balloon Guide Catheter (BGC), distal filter protection, and active aspiration through an intermediate catheter.
|
Balloon guide catheter for proximal flow arrest and debris aspiration during carotid stenting.
|
|
Aktiver Komparator: Standard Protection Group (Filter Alone)
Participants in this arm will undergo carotid artery stenting (CAS) with distal filter protection.
|
Distal embolic filter deployed beyond the stenosis to capture debris during stent placement.

Maßnahmenbeschreibung |
Zeitfenster |
|---|---|---|
|
Number of new infarcts on cerebral diffusion-weighted imaging (DWI) within 48 hours (±24 hours) post-procedure
Zeitfenster: within 48 hours (±24 hours) post-procedure
|
Total number of new DWI positive lesions on post procedural brain MRI within 48 hours (±24 hours).
New lesions are defined as foci of hyperintensity not seen on baseline DWI (if available), or otherwise as lesions consistent with acute embolic infarction.

|
Incidence of Major Adverse Events (MAE) within 30 days, including any stroke, death, and myocardial infarction.
Zeitfenster: within 30-day post-procedure
|
The rate of major adverse events (MAE), defined as the cumulative incidence of any death, stroke, or myocardial infarction within 30-day post-procedure.

|
|
Changes in mRS score at 30 days and 90 days post-procedure.
Zeitfenster: 30 days and 90 days post-procedure

30 days and 90 days post-procedure
|
|
Incidence of ipsilateral target vessel stroke at 30 days and 90 days post-procedure.
Zeitfenster: 30 days and 90 days post-procedure

30 days and 90 days post-procedure
|
|
Incidence of transient ischemic attacks (TIA) at 30 days and 90 days post-procedure.
Zeitfenster: 30 days and 90 days post-procedure
|
Transient ischemic attacks (TIA) was defined as transient focal neurological deficit of vascular origin lasting <24 hours with no acute infarct on neuroimaging.
|
30 days and 90 days post-procedure
|
|
Incidence of Procedure-related complications (e.g., vessel dissection, hyperperfusion syndrome, etc.).
Zeitfenster: during the procedure
|
Procedure related complications include vessel dissection, hyperperfusion syndrome, access site events, and other adverse events directly attributable to carotid artery stenting (CAS).
