Name of the Procedure:

Duplex Scan of Aorta, Inferior Vena Cava, Iliac Vasculature, or Bypass Grafts; Complete Study (Commonly known as Duplex Ultrasonography)

Summary

A duplex scan is a non-invasive imaging procedure that uses ultrasound technology to assess blood flow and anatomy of the aorta, inferior vena cava, iliac vessels, and any bypass grafts. This complete study helps in identifying any blockages, narrowing, or abnormalities in these major blood vessels.

Purpose

Medical Conditions Addressed:

• Aneurysms
• Blood clots
• Vascular stenosis (narrowing of vessels)
• Post-surgical assessment of bypass grafts

Goals:

• To evaluate the structure and function of major blood vessels.
• To detect any abnormalities, clots, or blockages.
• To monitor the patency and functionality of bypass grafts.

Indications

Symptoms:

• Leg pain while walking (claudication)
• Swelling of the legs or abdomen
• Sudden severe chest or abdominal pain
• Known vascular disease follow-up

Patient Criteria:

• History of vascular surgeries
• Patients with risk factors for vascular disease (e.g., high cholesterol, hypertension)
• Follow-up for previously diagnosed vascular conditions

Preparation

• No specific fasting required.
• Inform the healthcare provider about any medications you are taking.
• Wear comfortable, loose-fitting clothing.
• A recent blood test may be required to check kidney function, especially if contrast material is used.

Procedure Description

• You will lie on an examination table.
• A gel is applied to the skin over the area to be examined.
• A transducer (a device that sends and receives ultrasound waves) is moved over the area.
• The ultrasound generates images of blood flow and vessel structure on a computer screen.
• In some cases, Doppler ultrasound may be used to measure the speed and direction of blood flow.

Technology Used:

• Ultrasound machine
• Transducer
• Gel for transducer-skin contact enhancement

Anesthesia:

• No anesthesia or sedation is typically required.

Duration

The procedure typically takes between 30 minutes to 1 hour.

Setting

The duplex scan is usually performed in a hospital, outpatient clinic, or a specialized imaging center.

Personnel

• Radiologist or Vascular Technician
• Sometimes a Vascular Surgeon is available for consult

Risks and Complications

Common Risks:

• Generally, a very low-risk procedure

Rare Complications:

• Discomfort from the transducer pressing on the skin
• Rare allergic reaction to the gel used

Benefits

Expected Benefits:

• Non-invasive and painless
• Provides detailed information about blood flow and vessel condition
• Helps in early detection of vascular issues

Realized Benefits:

• Results are typically available immediately or shortly after the procedure.

Recovery

Post-Procedure Care:

• No specific post-procedure care required.
• Patients can resume normal activities immediately.

Recovery Time:

• Immediate return to normal activities with no downtime.

Follow-Up:

• Follow-up appointments depend on the findings of the scan and patient’s condition.

Alternatives

Other Treatment Options:

• MRI Angiography
• CT Angiography
• Traditional Angiography

Pros and Cons:

• MRI and CT angiograms provide detailed images but involve radiation or contrast material.
• Traditional angiography is more invasive and involves catheterization but provides very detailed vessel images.

Patient Experience

During the Procedure:

• You might feel slight pressure from the transducer.
• The gel might feel cold on the skin.

After the Procedure:

• You might experience some minor discomfort from the gel but no pain.
• Pain management is not typically necessary as the procedure is non-invasive and painless.
