About this study

Official title: Radial Versus Femoral Access For Carotid Artery Stenting In Patients With Carotid-Artery Stenosis :a Prospective, Randomized, Multicenter, Noninferiority Trial

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, or new-onset stroke, or myocardial infarction, or severe hemorrhage events within 48 hours post-procedure. 2. The incidence of death, new-onset stroke and myocardial infarction within 48 hours / 30 days post-procedure. 3. The incidence of death within 48 hours / 30 days post-procedure. 4. The incidence of new-onset stroke within 48 hours / 30 days post-procedure. 5. The incidence of myocardial infarction within 48 hours / 30 days post-procedure. 6. The incidence of severe hemorrhage events within 48 hours / 30 days post-procedure. Other end points: 1. Successful rate of cerebral angiography. 2. Successful rate of CAS. 3. Degree of patient-reported comfort. 4. Operation time. 5. NIHSS score changes within 5-7 days post-procedure. 6. mRS score score within 30 days post-procedure.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Carotid Artery Stenting (CAS)Procedure or surgery

    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.

A study testing Carotid Artery Stenting (CAS) in people with Ischemic Stroke and Carotid Stenosis, run by The First Affiliated Hospital of University of Science and Technology of China at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 14 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The incidence of death, or new-onset stroke, or myocardial infarction, or severe hemorrhage events within 30 days post-procedure (time frame: 30 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05416853, which also lists 10 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jul 2026.
