About this study

Official title: Imaging Research on Anatomical Variation of Cerebral Venous Sinus in Healthy Individuals

The anatomical characteristics of veins and venous sinus result in great differences between cerebral venous system diseases and cerebral artery diseases in etiology, pathophysiology and clinical features.Therefore, understanding the anatomy and variation of normal venous sinuses is essential to identify the intracranial venous lesions.

Read the detailed description

The classification of venous sinus and its variation based on the autopsy of patients can not fully reflect the real anatomy and variation of venous sinus in human, and the targeted research on healthy people is still unknown. The main purpose of this research is to use multimodal magnetic resonance technology to study the variation of venous sinus in Chinese healthy population, to preliminarily improve the anatomical classification of venous sinus in Chinese , to verify the the correlation between venous sinus variation and various non-genetic factors at the same time, as well as establishing reliable quantitative evaluation indicators.

Being tested
anotomy and variation of venous sinus, the level of biomarker in bood
Keywords
venous sinus, anatomy
Medical subject headings

What participants receive

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

  • anotomy and variation of venous sinusDiagnostic test

    Contrast enhanced-magnatic resonance venography(CE-MRV)and other magnetic resonance imaging methods are used to estimate the anatomy of cerebral venous sinus.

  • the level of biomarker in boodDiagnostic test

    Elisa or omics analysis is used to test the level of biomarker in blood.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The anotomy and variation of venous sinus in Chinese healthy individuals

    According to the connection types of superior sagittal sinus and transverse sinus at the the torcular Herophili assessed with contrast-enhanced MR venography and phase-contrast MR venography, describe the anatomical classification of venous sinus based on the anatomical descriptions of Osborn and describe the anatomical variations that are not included in the existing classification. Calculating the proportion of each type.

    Measured: On the day of examination

Secondary outcomes (2)
  1. The diameters of venous sinus and small veins in Chinese healthy individuals

    Measuring the diameters of venous sinus and small veins assessed with contrast-enhanced MR venography

    Measured: On the day of examination

  2. Serum biomarkers in Chinese healthy individuals

    The level of biomarkers are detected using Elisa or omics analysis

    Measured: On the day of examination

Questions about this trial

What is this clinical trial studying?

An observational study of Venous Sinus Thrombosis, Cranial, run by Capital Medical University 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 3 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 18 Apr 2023. 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?

Results are not available in the source record.

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

Contact Xunming Ji, MD.PhD (010-83199430, jixm@ccmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The anotomy and variation of venous sinus in Chinese healthy individuals (time frame: On the day of examination). 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 NCT05413837, 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 18 Apr 2023.
