OVERVIEW
This issue contains a letter to the editor, a review on the IAC QI self-assessment tool, the usefulness of the external carotid artery in detecting internal carotid artery stenosis, a review of transcranial Doppler in detecting a patent foramen ovale, various abstracts selected for the SVU Poster Session, a case report on the migration of an Amplatzer Vascular Plug II, and images of a portal venous aneurysm.

LEARNING OBJECTIVES
After reading and studying the papers used for CME in the March 2023 Issue of the Journal for Vascular Ultrasound, participants will be able to:
1. State the various components of the IAC– QI self-assessment tool.
2. List the technical errors the vascular technologist revealed on the venous duplex exam.
3. Explain the factors that may result in an incomplete or non-optimized exam.
4. List the limitations of using CT angiography as the gold standard for external carotid artery stenosis.
5. Describe the technical limitations of visualizing the internal carotid artery with duplex ultrasound.
6. List the parameters used to categorize internal carotid stenosis with duplex ultrasound.
7. State the most common injection site for an agitated saline bubble study.
8. Explain the Muller maneuver.
9. Explain the importance of performing a Valsalva maneuver after injection of the agitated saline bubbles.
10. Describe the characteristics of juvenile temporal arteritis.
11. Describe the ultrasound characteristics of fibromuscular dysplasia.
12. State the clinical presentation of reversible cerebral vasoconstriction syndrome.
13. Describe an Amplatzer Plug II.
14. State the surgical location of an Amplatzer Plug II.
15. Explain why the left arterial pulsed Doppler waveform remained multiphasic with a greater than seventy-five percent stenosis.
16. State the most common location for portal venous aneurysms.
17. Explain hepatopetal flow.
18. Compare the difference between an acquired and congenital portal venous aneurysm.

TARGET AUDIENCE
