When it comes to heart disease, an abdominal ultrasound is used as a diagnostic tool for screening “AAA,” or an abdominal aortic aneurysm. The aorta is the main blood vessel that supplies blood to our abdomen, pelvis, and legs. An abdominal aortic aneurysm occurs when part of the aorta becomes very large or bulges out.
The larger the aneurysm, the more likely it is to rupture, and unfortunately this can be life-threatening. Some of the risk factors can be:
- Age 65 or older
- High blood pressure
- Male gender
- Family history or genetics
Aneurysms can progress slowly over a long period of time, often without symptoms. Symptoms may come on suddenly if the aneurysm expands rapidly, splits open or seeps blood within the wall of the aorta (aortic dissection). The rupture of an abdominal aortic aneurysm is a serious medical emergency. Call 911 and seek immediate medical attention if you have extreme pain in your abdomen or back that does not go away.
Symptoms of a rupture that require abdominal ultrasound:
- Severe, sudden or throbbing pain in the abdomen or back that remains constant
- Nausea or vomiting
- Rapid heart rate
If you are without symptoms and the aneurysm is small:
- Surgery is usually not necessary
- Risks of surgery should be weighed, considered and discussed
- Dr. Fenster may want to schedule regular follow-up appointments to re-check the AAA.
Surgery is usually done if the aneurysm is more than 2 inches (5.5 cm) across or growing rapidly. The objective is to do surgery before complications develop.
To reduce the risk of aneurysms:
- Eat a low-fat, high-fiber diet, exercise, reduce stress, and stop smoking
- Take your medications as directed
- If you have ever smoked and are over age 65, you should have at least one screening ultrasound
To prepare for the test:
- Fast for 8 hours prior to the ultrasound
A specially trained technician (sonographer) will perform your abdominal ultrasound. A small amount of warm gel is applied to your abdomen and the technician will press an instrument called a transducer over your skin, moving from area to area in order to view the aorta from all angles. These images will be viewed on the computer screen so the technician can monitor blood flow through your aorta and check for an aneurysm.
Dr. Fenster will review the images from your ultrasound to see if you have an abdominal aortic aneurysm and will discuss the results with you as soon as they are available. He may recommend the following if you have one:
- No treatment, just follow up. In the case that your aneurysm is smaller than 2 inches in diameter, we may ask to recheck your condition regularly for changes, using additional ultrasound exams or other imaging tests.
- Open repair. In the case that your aneurysm requires surgery, one option is to have an open aneurysm repair. A board-certified cardiac surgeon would be recommended for this procedure.
- Endovascular surgery. Another option is to have a surgeon perform an endovascular stent graft. This reinforces the weakened portion of the abdominal aorta by threading a graft through a catheter. The graft helps to support the weakened portion of your aorta so that it won’t rupture.
Where will the abdominal ultrasound be performed?
The ultrasound will be performed right in Dr. Fenster’s office:
Cardiac Institute of the Palm Beaches, PA
108 Intracoastal Pointe Drive
Jupiter, FL 33477
If you have any questions about your procedure, please call us.
