Abdominal Aortic Aneurysm, Image
Conditions
Brief summary
The aim of this study is to investigate the measurement of abdominal aortic aneurysm by computed tomography angiography. The research will collected the results of computed tomography angiography from inpatient, emergency, and outpatient populations with abdominal aortic aneurysm.
Detailed description
Abdominal aortic aneurysm (AAA) is a life-threatening vascular disorder characterized by irreversible dilation of the abdominal aorta, posing a significant risk of rupture and catastrophic hemorrhage, with mortality rates reaching 65-85% upon rupture. Given the often asymptomatic nature of AAA until rupture, early detection and precise monitoring are critical to prevent fatal outcomes, underscoring the urgent need for reliable diagnostic tools. Computed tomography angiography (CTA) has emerged as a gold-standard non-invasive imaging technique, offering high-resolution visualization of AAA morphology, including aneurysm diameter, wall thickness, thrombus formation, and spatial relationship to adjacent structures, which are essential for accurate diagnosis, rupture risk stratification, and surgical planning. This study aims to investigate the precision and clinical utility of CTA in AAA measurement, with the potential to optimize screening protocols, improve intervention timing, and ultimately reduce AAA-related mortality. By establishing standardized CTA-based assessment criteria, this research may contribute to enhanced diagnostic workflows, better patient risk stratification, and more personalized treatment strategies, thereby addressing a critical gap in vascular disease management.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Maximal abdominal aortic diameter | 1 month | The images of computed tomography angiography on abdominal aortic aneurysm are collected and the maximal diameter of abdominal artery is measured by medical specialists. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Rupture | 1 month | The images of computed tomography angiography on abdominal aortic aneurysm are collected and the rupture of AAA is judged by medical specialists. |
