CTA registry for abdominal aortic aneurysm measurements

Official title: Abdominal Aortic Aneurysm CTA Cohort Study (AAA-CTA Registry)

Run by RenJi Hospital · NCT07039825 · Data updated 2026-11-12

This registry will collect CT angiography scans from people with abdominal aortic aneurysms to see if CTA measurements reliably describe aneurysm size and features.

Is this trial a fit for you?

Likely a good fit

Adults diagnosed with abdominal aortic aneurysm who have available CTA imaging and who were seen as inpatients, emergency patients, or outpatients at RenJi Hospital.

Probably not a fit

People without CTA imaging, with incomplete or missing clinical data, or whose care does not rely on imaging measurements are unlikely to benefit from this registry.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational registry will collect computed tomography angiography (CTA) images and measurement data from inpatient, emergency, and outpatient populations at RenJi Hospital who have abdominal aortic aneurysm. Radiologic and clinical data will be compiled to examine measurement reproducibility and detailed aneurysm morphology including diameter, wall thickness, and intraluminal thrombus. The project aims to establish standardized CTA-based assessment criteria to improve rupture risk stratification and guide timing of interventions. Data will be analyzed using descriptive statistics and reproducibility measures to inform screening protocols and surgical planning.

Why it matters

Potential benefit: If successful, the registry could lead to standardized CTA measurements that improve risk stratification and timing of interventions, potentially reducing AAA-related ruptures and deaths.

How similar studies have gone: CTA is already a widely used and accurate method for characterizing AAA morphology in prior studies, though large standardized registries to harmonize measurement criteria remain limited.
