Name of the Procedure:

Ultrasound B-Scan and/or Real-Time with Image Documentation for Abdominal Aortic Aneurysm (AAA) Screening
Technical term: G0389

Summary

This non-invasive ultrasound procedure involves using sound waves to create real-time images of the abdominal aorta. It helps screen for the presence of an abdominal aortic aneurysm (AAA), which is a dangerous swelling of the aorta that can lead to severe health risks if not detected early.

Purpose

The procedure primarily addresses the detection of abdominal aortic aneurysms. The goal is to identify such aneurysms early and monitor their size, preventing rupture by appropriate medical intervention.

Indications

• Men aged 65 and older
• Patients with a family history of AAA
• Individuals who have ever smoked
• Patients with other risk factors such as hypertension or atherosclerosis

Preparation

• Typically, patients are instructed to fast for 6-8 hours before the procedure to reduce bowel gas, which can interfere with imaging.
• Wear comfortable, loose-fitting clothing and possibly a gown provided by the clinic.

Procedure Description

1. The patient lies on their back on an examination table.
2. A clear, water-based gel is applied to the abdomen to facilitate sound wave transmission.
3. A transducer (a hand-held device) is moved over the abdomen to obtain images.
4. The real-time images are displayed on a monitor and documented for further analysis.
5. The procedure does not typically require anesthesia.

Duration

The ultrasound procedure usually takes about 30 minutes to complete.

Setting

The procedure is commonly performed in an outpatient clinic, hospital, or diagnostic imaging center.

Personnel

• A sonographer or radiologic technologist conducts the ultrasound.
• A radiologist or a physician interprets the results.

Risks and Complications

• This is a very low-risk procedure.
• Rarely, patients may experience slight discomfort from the transducer’s pressure on the abdomen.
• No radiation exposure is involved.

Benefits

• Early detection of an AAA can significantly reduce the risk of rupture and associated complications.
• Immediate results and a painless, non-invasive experience.
• Can help guide further medical or surgical treatment if an aneurysm is detected.

Recovery

• No recovery time is needed.
• Patients can resume their normal activities immediately post-procedure.
• Follow-up appointments may be necessary based on the results.

Alternatives

• CT Angiography: Provides detailed images but involves contrast dye and radiation.
• MRI: Also provides detailed images without radiation but is more expensive and less accessible.
• Physical Examination: Not as reliable as imaging for detecting AAAs.

Patient Experience

• Some mild pressure from the transducer may be felt, but otherwise, the procedure is painless.
• Fasting might cause some discomfort or hunger beforehand.
• The patient might feel the coolness of the gel applied to the abdomen but should be comfortable during and after the procedure.
• Results are usually discussed with the patient shortly after the screening, providing immediate peace of mind or next steps if an aneurysm is detected.
