Objectives: After studying the article, you should be able to:

• Recall criteria for duplex sonographic appearance of graft types in patients who underwent femoral artery reconstruction surgery.

• Summarize the role of duplex ultrasonography (DUS) in patients with peripheral artery disease (PAD).

• Describe the importance of documenting the relationship and hemodynamics of grafts and vascular landmarks in post-op bypass patients.

1. How many patients in the study from the article had above the knee femoropopliteal 8mm synthetic graft bypass with end-to-end proximal anastomosis?

2. In the cohort of authors from the article, what native vessel was observed increasing in diameter when evaluated with sonography post bypass?

3. The Table 1 results indicate a one-year post-treatment patency percentage rate of ____ for patients who underwent femoropopliteal saphenous vein revascularization with end-to-side anastomosis.

4. What is the number 2 arrow pointing to on the grayscale image B of Figure 4 in the article?

5. Figure 9, which shows a longitudinal section of the CFA bifurcation area in a patient after a femoropopliteal bypass graft using an end-to-end anastomotic technique, displays the PFA at what degree of angulation?

6. One of the limitations listed in the study was ________.

7. What is the arrow pointing to in Figure 6?
