Peripheral Arterial Exam

It helps detect Peripheral Artery Disease (PAD), a condition where arteries become narrowed or blocked due to plaque buildup.

1. Ankle-Brachial Index (ABI)

• Compares blood pressure in your ankle vs. your arm
• Lower pressure in the ankle can mean blocked arteries

2. Doppler ultrasound

Uses sound waves to:

• Visualize blood flow
• Detect blockages or narrowing

3. Segmental pressure testing

• Measures blood pressure at different points along your legs
• Helps pinpoint where a blockage may be

4. Pulse volume recordings (PVR)

• Measures changes in blood volume with each heartbeat

• Blood pressure cuffs are placed on your arms and legs
• A small ultrasound probe may be used

You may be tested:

• At rest
• After walking on a treadmill (to reveal hidden problems)

• Whether blood flow is normal or reduced
• The location and severity of any blockages
• How well your circulation responds to activity

Doctors may order it if you have:

• Leg pain when walking (claudication)
• Numbness or weakness in legs
• Cold feet or slow-healing wounds
• Known risk factors (smoking, diabetes, high cholesterol)
