About this study

Official title: Cohort of Optimized Assessment Strategy of Carotid Artery Stenosis

The goal of this observational study is to learn about how to utilize multiple evaluation techniques in carotid artery stenosis patients for optimizing assessment of diagnosis and treatment strategy.

The main questions it aims to answer are:

  • Identify best strategy that use multi-modal MRI and CT to assess patients' cerebral lesions and perfusion.
  • Identify best strategy that use multi-modal MRI, PET-MRI ultrasound and CT to assess components and characters of patients' carotid plaques.

Participants will accept imaging examination before and after surgery. And doctors will collect basic characteristics, imaging results and biological samples of patients for analysis.

Being tested
Carotid revascularization, MRI-PWI, CTA, PET/MRI, Ultrasound
Keywords
carotid artery stenosis, Perfusion, plaque, MRI, CT, PET/MRI, Ultrasound
Medical subject headings
Carotid Stenosis, Plaque, Amyloid

What participants receive

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

  • MRI-PWIDiagnostic test

    Multi-modal MRI before and after surgery.

  • CTADiagnostic test

    CTA before and after surgery.

  • PET/MRIDiagnostic test

    PET/MRI before surgery.

  • UltrasoundDiagnostic test

    Ultrasound before and after surgery.

Questions about this trial

What is this clinical trial studying?

An observational study of Carotid Artery Stenosis, run by Peking Union Medical College Hospital 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 2 inclusion and 1 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: looking for participants now, as of the sponsor's last update on 29 Nov 2022. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Zhichao Lai, MD (01069152500, zhichao_lai@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

stroke (time frame: During hospital stay, usually 7-30 days post operation). The study lists 5 primary outcomes in all. 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 NCT05629000, which also lists 1 linked publication.

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 29 Nov 2022.
