Objectives: After studying the article entitled “Lower Extremity Arterial Duplex, Toe-Brachial Index, and Computed Tomography Angiography Examinations in Peripheral Arterial Disease: A Case Presentation,” you will be able to:

1. Understand the role of non-invasive arterial duplex and toe-brachial index for peripheral arterial disease

2. Understand the supportive role of the toe-brachial index

3. Compare arterial duplex, arterial physiologic testing, and computed tomography angiography in diagnosis peripheral arterial disease

1. What is the maximum normal range in mmHg between arm blood pressure recordings that is acceptable?

2. 1-5 mmHg

3. 10-15 mmHg

4. >20 mmHg

What did the computed tomographic angiogram demonstrate that correlated with the arterial duplex exam?

Mid SFA occlusion

Popliteal artery and proximal anterior tibial artery stenosis

Distal SFA stent extending into the proximal PTA was occluded

Mid and distal SFA, popliteal artery, tibioperoneal trunk artery occlusion

When is a segmental pressure examination not contraindicated?

Arterial bypass graft

Arterial wound on the lateral ankle

Arterio-venous fistula presence

Arterial stent presence

The most common arterial stenosis site in the legs is located where?

Distal SFA

Common femoral and proximal superficial femoral artery bifurcation

Tibioperoneal arterial trunk location

Anterial tibial arterial ostial segment

What does photoplethsymography detect?

Photo sensitive capillary dilation

Transmetatarsal arterial volume

Variations in cutaneous blood flow

Amount of infrared light absorption of the digital artery
