  • Pregnancy;
  • With a history of intracranial arteriovenous malformation, Moyamoya, polycystic kidney disease, Ehlers-Danlos syndrome, Gronblad-Strandberg syndrome, or Marfan syndrome;
  • Suspicion for dissecting or mycotic aneurysms or aneurysm-like lesions that were indistinguishable from the infundibulum, fenestration, dilation, or atherosclerotic remodeling on structural imaging scans.

About this study

Official title: Epidemiological Insights Into the Formation, Progression, and Rupture of Aneurysms: A Retrospective, Multi-Center Hospital-Based Study in China

This is a retrospective, hospital-based and multi-center study aiming at investigating the potential exposures associated with the formation, progression, and rupture of intracranial aneurysms in Chinese population.

Read the detailed description

A striking conflict exists between the fatal rupture of intracranial aneurysms (IA) and the passive approach to detecting IA through cerebrovascular examinations. This is attributed to a limited understanding of risk factors for IA incidence and the resulting lack of cost-effective IA screening.

This study aims to gain epidemiological insights into the exposures associated with the risk of IA incidence, including formation, progression, and rupture in the Chinese population. It integrates multi-modal data based on large-scale electronic medical records from high-volume stroke centers across China to investigate potential associations between various exposures and IA incidence.

Patients with anonymous and unique IDs were screened for the presence of IA by formal readings from digital subtraction angiography (DSA), cranial computed tomography angiography (CTA), or magnetic resonance angiography (MRA) conducted by two radiologists, which were then confirmed by two treating neurosurgeons using the raw images. Using natural language processing in conjunction with medical records and multi-modal data, patient exposures were extracted and assumed to be absent if no documentation was found across the databases.

Through a series of retrospective analyses, we aim to identify the exposures associated with IA incidence as much as possible to gather valuable insights for future prospective research.

Questions about this trial

What is this clinical trial studying?

An observational study of Intracranial Aneurysm and Subarachnoid Hemorrhage, Aneurysmal, run by Zhujiang 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 4 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: looking for participants now, as of the sponsor's last update on 13 Jun 2024. 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 Chuanzhi Duan, MD, PhD (15622311746, doctor_duanzj@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Intracranial aneurysm (time frame: 2010.01.01-2024.06.01). 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 NCT06456814, 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 13 Jun 2024; AzTrials last refreshed its copy on 8 Nov 2026.
