Abdominal Aortic Aneurysm (AAA) screening is a non-invasive ultrasound test that examines the abdominal aorta for enlargement or aneurysm formation. It helps detect aneurysms early to prevent life-threatening rupture.
Procedure Breakdown:
- Preparation:
- Patients may be asked to fast for 6–8 hours before the test to minimize interference from bowel gas.
- Gel Application:
- A water-based gel is applied to the abdomen to enhance sound wave transmission.
- Ultrasound Imaging:
- A handheld transducer is moved over the abdomen to visualize the aorta.
- The technician takes measurements of the aortic diameter.
- Aneurysm Detection:
- The test identifies any enlargement of the aorta.
- If an aneurysm is present, its size and risk factors are evaluated.
- Completion & Results:
- The procedure takes about 15–30 minutes.
- A vascular specialist reviews the images and provides results to the referring doctor.
AAA screening is a quick, painless, and effective method for detecting aneurysms early and preventing complications.
