Lower Extremity Arterial

How should the normal lining of the arterial blood vessels be?

• Thick

• Thin

• Rough

• Smooth

Answer explanation

The inner lining of arterial blood vessels is normally smooth, allowing blood to flow easily.

In lower extremity arterial disease, the lining becomes damaged, leading to buildup of cholesterol and other lipids, causing the arterial wall inner lining to become rough and thickened.

What is the name of the disease in which cholesterol and other lipids accumulate on the walls of the artery?

• Atherosclerosis

• Peripheral Arterial Disease

• Stenosis

• Thrombosis

What is the name of the diseases when the arteries become narrowed or blocked resulting in decreased blood flow?

• Atherosclerosis

• Peripheral Arterial Disease

• Stenosis

• Thrombosis

What is the most common symptom of peripheral arterial disease?

• Claudication

• Ischemic Rest Pain

• Tissue Loss

• Extremity Discoloration

When does claudication occur?

• During standing

• During rest

• During exercise

• All of the time

Answer explanation

Claudication occurs due to inadequate blood supply during exercise and subsides with rest.

Where does the dorsalis pedis artery originate?

• Posterior Tibial Artery

• Anterior Tibial Artery

• Popliteal Artery

• Superficial Femoral Artery

What are severe symptoms of peripheral arterial disease?

• Claudication

• Tissue Loss/Necrosis

• Ischemic Rest Pain

• Calf Pain

Where does the common femoral artery originate?

• Aorta

• Internal Iliac Artery

• External Iliac Artery

• Superficial Femoral Artery

How is the amount of narrowing of an artery determined?

• Gray scale visual estimation

• Presence of color doppler aliasing

• Appearance of doppler spectral waveform

• Peak systolic velocity measuring on a spectral waveform

Which of these are a sign of >50% stenosis?

• Peak systolic velocity of 90 cm/sec

• Peak systolic velocity of 200 cm/sec

• Monophasic waveform

• Spectral broadening
