AA Doppler

Abdominal Aortic Doppler​

The non-invasive abdominal aortic Doppler test utilizes Doppler ultrasound to measure blood flow in the abdominal aorta. It aids in evaluating aortic aneurysms, monitoring blood flow, and detecting related complications.

Why you need a diagnostic test

Usually, abdominal aortic Doppler is used to:

1. Determine whether there is an abdominal aortic aneurysm (AAA), which is a bulge or weak region in the aorta’s wall.

2. Track the expansion of an existing AAA.

3. Analyze the aorta’s blood flow.

4. Analyze the possibility of a known or suspected AAA rupturing.

5. Help in making decisions about whether a AAA needs to be treated or repaired.

The non-invasive test gives medical professionals a good view of the abdominal aorta’s condition, which is crucial for monitoring and averting future consequences.

How does it work?

Abdominal aortic Doppler employs Doppler ultrasound to measure blood flow velocity in the abdominal aorta. Using a transducer on the abdomen, high-frequency sound waves bounce off red blood cells, producing echoes. These echoes are converted into images, revealing aortic blood flow. The Doppler effect measures velocity, offering insights into aorta health and aneurysm presence.

The procedure

The non-invasive abdominal aortic Doppler technique usually takes 30 minutes to perform. An summary of the process is provided here:

1. Preparation – In order to increase the transmission of the sound waves, the patient is typically instructed to lie down on an exam table while a gel is placed to the abdomen.

2. Ultrasound exam – To get clear images of the abdominal aorta, the technician will position the transducer on the abdomen and move it around.

3. Data collection – The abdominal aorta’s blood flow velocity and direction are measured by the Doppler ultrasound, and the results are shown on a monitor. The technician may record a video or take still pictures to show the doctor the blood flow.

4. Results interpretation – The results of the test will be interpreted by a healthcare professional to establish the size and likelihood of rupture of any abdominal aortic aneurysms, as well as any problems with blood flow in the aorta.

The test does not require any specific preparation, and it is often a simple and painless process. Following the examination, the patient can resume regular activities.
