OVERVIEW

This issue includes a review of factors influencing accreditation in extracranial ultrasound studies, an overview of CO2 reactivity in the brain and its dependance on blood pressure regulation and arteriolar vasoreactivity, a report assessing the testicular artery resistive index in men with oligoastenospermic infertility, a case report on carotid body tumors, a case report on idiopathic popliteal arteriovenous fistula, images in vascular ultrasound highlighting Amussat’s sign, a blunt traumatic carotid dissection, an educational article featuring a simulated ballistic gelatin mold designed to mimic a pseudo aneurysm, and a technical note assessing left renal vein compression using diagnostic ultrasound.

LEARNING OBJECTIVES

After reading and studying the papers used for CME in the September 2025 issue of the Journal of Vascular Ultrasound, participants will be able to:

1. List the significant factors that contribute to “delayed” accreditation in extracranial carotid artery ultrasound studies.
2. Explain the Delphi method.
3. List key parameters used during the accreditation review process.
4. Explain arterial acceleration with duplex ultrasound.
5. Explain why the heart rate increases with hyperventilation compared to normal ventilation.
6. List the symptoms associated with hyperventilation-induced cerebral ischemia.
7. State the ages when fertility in men peak and sharply dimmish.
8. List risk factors that cause infertility in men.
9. State the formula used to calculate a resistive index.
10. Define paraganglioma.
11. Explain the location of the flow divider on a carotid duplex examination.
12. Explain why patients living in a higher altitude are at a higher risk of developing a carotid body tumor.
13. Define an arteriovenous fistula.
14. Describe the flow characteristics of an arteriovenous fistula.
15. List treatment options for patients with an arteriovenous fistula.
16. Describe the characteristics of the Amussat’s sign seen on computed tomography.
17. Define pseudoaneurysm.
18. List treatment options for repairing a pseudoaneurysm.
19. State the cause of a pseudoaneurysm.
20. Describe superior mesenteric syndrome.
21. Describe nutcracker syndrome.
22. Explain the common anatomical configuration of nutcracker syndrome.
