CCI Peripheral Arterial Evaluation 2

Question 1

A patient with an ABI of 0.55 complains of calf pain after walking one block. Which classification best describes this patient's peripheral arterial disease severity?

Accepted Answer

Moderate PAD

Answer

An ABI of 0.41–0.70 with claudication at short distances indicates moderate PAD.

Question 2

During a lower extremity arterial duplex exam, you detect a peak systolic velocity (PSV) ratio of 4.2 at the superficial femoral artery. What does this ratio indicate?

Accepted Answer

75–99% stenosis

Answer

A PSV ratio greater than 4.0 at a stenotic segment indicates 75–99% diameter reduction.

Question 3

Which waveform pattern is expected at the common femoral artery in a normal, resting adult patient?

Accepted Answer

Triphasic with reverse flow component

Answer

The normal resting common femoral artery waveform is triphasic with a reverse flow component during early diastole.

Question 4

A patient's toe-brachial index (TBI) is 0.55. What is the most appropriate clinical interpretation?

Accepted Answer

Abnormal — suggests significant digital arterial disease

Answer

A TBI below 0.70 is considered abnormal and indicates significant reduction in digital perfusion.

Question 5

When performing segmental limb pressures, which cuff placement helps distinguish aortoiliac disease from femoral disease?

Accepted Answer

High-thigh and above-knee cuffs

Answer

A gradient between the high-thigh and above-knee cuff pressures localizes disease to the aortoiliac or femoral segment.
