Brief Summary

Background: For moderate to severe carotid artery atherosclerotic stenosis, in the past decades, carotid artery stenting (CAS) has been an alternative to carotid endarterectomy (CEA) for the treatment of carotid artery stenosis. The transfemoral artery (TFA) using Seldinger's technique has been the most commonly used approach for CAS. The radial artery is an ideal puncture site for cerebrovascular intervention. Studies have shown that nerve intervention through radial artery approach can complete most cerebrovascular intervention procedures, including cerebral angiography, carotid artery stent implantation, vertebral artery stent implantation, intracranial artery stent implantation, mechanical thrombectomy, aspiration, intra-arterial thrombolysis and so on. However, the current studies are based on single center small sample studies, and there has been still a lack of large sample randomized controlled experiments to verify the safety and effectiveness of CAS in transradial artery (TRA) .

Objective: To evaluate the efficacy and safety of CAS via TRA in patients with carotid artery stenosis through a multicenter, prospective and randomized study.

Study design: This study is a randomized, open label, multicenter, parallel controlled trial. A non-inferiority test is performed to compare the primary end point between the experimental group and the control group. The experimental group will undergo carotid stent implantation via radial artery approach, while the control group will use femoral artery approach.

Study population: Adult patients with symptomatic carotid-artery stenosis ≥50% or asymptomatic stenosis ≥70%.

Study outcomes: Primary end points: The incidence of death, or new-onset stroke, or myocardial infarction, or severe hemorrhage events within 30 days post-procedure Secondary end points:1. The incidence of death, new-onset stroke and myocardial infarction within 48 hours / 30 days post-procedure. 2. The incidence of death within 48 hours / 30 days post-procedure. 3. The incidence of new-onset stroke within 48 hours / 30 days post-procedure. 4. The incidence of myocardial infarction within 48 hours / 30 days post-procedure. 5. The incidence of severe hemorrhage events within 48 hours / 30 days post-procedure. Other end points: 1. Successful rate of DSA. 2. Successful rate of endovascular treatment. 3. Degree of patient-reported comfort. 4. Operation time 5. NIHSS score changes post-operation.6. mRS score score changes post-operation. 7. X-ray exposure. Safety outcomes: 1.Occurrence of all adverse events. 2. AEs related to operation and device. 3. Incidence of adverse event of special interest.

Study Groups

Transradial artery

Carotid stent implantation via radial artery approach

Group Type: ACTIVE_COMPARATOR

Carotid Artery Stenting (CAS)

Intervention Type: PROCEDURE

CAS involves insertion of a catheter or tube into an artery in the groin or the radial, and then threading the catheter through the arteries of the body to the location of the plaque within the carotid artery in the neck. A stent is then placed to cover the plaque and hold the artery open.

Transfemoral artery

Carotid stent implantation via femoral artery approach

Group Type: ACTIVE_COMPARATOR

Carotid Artery Stenting (CAS)

Intervention Type: PROCEDURE

CAS involves insertion of a catheter or tube into an artery in the groin or the radial, and then threading the catheter through the arteries of the body to the location of the plaque within the carotid artery in the neck. A stent is then placed to cover the plaque and hold the artery open.

Eligibility Criteria

Inclusion Criteria

1) Age≥18 years old

1. Symptomatic stenosis: patients had a transient ischemic attack (TIA), amaurosis, or minor nondisabling stroke involving the target carotid artery within 180 days before randomization.

2. Asymptomatic stenosis: The results of medical history, physical examination and neurological examination do not suggest ischemic symptoms in the target carotid artery. If artery stenosis degree reache the standard, but there are any one or more of the following symptoms including: non-carotid artery symptoms; contralateral carotid artery symptoms; time from symptom to randomization more than 180 days; and vertebrobasilar artery symptoms. In these situations, patients are considered to be asymptomatic.
