Society for Vascular Ultrasound 2022 Annual Conference Abstracts Selected for the Oral Case Study Session for CME Credit December 2022

1. (Late Embolization of an Amplatzer Vascular Plug: A Very Rare Complication Following Mitral Paravalvular Leak Repair). The Amplatzer vascular plug was visualized on ultrasound and resembled a ___________ figure eight shape within the artery.

A. Anechoic

B. Hypoechoic

C. Hyperechoic

D. Radiopaque

2. (Mid Aortic Syndrome) Mid aortic syndrome is a diffuse narrowing in the abdominal aorta. Clinical signs and symptoms include all of the following except:

A. Perivascular inflammation

B. Nausea and vomiting

C. Post-prandial pain

D. Renovascular hypertension

3. (Mid Aortic Syndrome) Mid aortic syndrome occurs most often in men age 65 and older.

A. True

B. False

4. (Arterial Duplex Studies of Imaging Amplatzer Plugs II as Foreign Bodies in the Right Arm) On duplex ultrasound, an Amplatzer Plug II was detected in the right proximal brachial artery. A monophasic Doppler waveform was seen proximal to the detection site suggesting a severe stenosis.

A. True

B. False

5. (Arterial Duplex Studies of Imaging Amplatzer Plugs II as Foreign Bodies in the Right Arm) In this case, the Amplatzer Plug II, although usually resistant to migration, became a migrating foreign body, impacting the patient’s upper and lower extremity arterial circulation.

A. True

B. False

6. (Left Internal Carotid Artery Dissection with Aneurysm on Carotid Duplex in a Patient with Habitual Chiropractic Manipulation) In this case, additional imaging was performed of the internal carotid and vertebral arteries which demonstrated all of the following findings except:

A. Non-mobile echogenic striation

B. Tortuous loop

C. Pre-steal waveform

D. Hemodynamically significant stenosis

7. (Transient Perivascular Inflammation [TIPIC] of the Common Carotid Artery Bifurcation Using Ultrasonographic B-Mode Imaging). Transient perivascular inflammation of the common carotid bifurcation is visualized on ultrasound as wall thickening with hypoechoic, homogenous tissue engulfing the arterial wall.

A. True

B. False

8. (Non-Anastomotic Pseudoaneurysm of Axillobifemoral Bypass Graft) A 75-year-old male presented with a rare pseudoaneurysm which formed in the _________ segment of the axillobifemoral graft, which may be due to a small defect in the graft material.

A. Origin

B. Proximal

C. Mid

D. Distal

9. (Rare Case of Internal Jugular Vein Invasion by Thyroid Carcinoma) Internal jugular vein tumor thrombosis is a rare occurrence. Color duplex ultrasound revealed increased vessel distention, tumor invasion into the vessel wall, and neovascularity within the thrombus.

A. True

B. False

10. (Benefits of Ultrasound-Guided Cannulation for Dialysis Vascular Access: A Vascular Technologist’s Perspective) The complications seen in patients receiving ultrasound-guided arteriovenous fistula cannulation included all of the following except:

A. Development of thrombus

B. Needling complications

C. Pseudoaneurysm formation

D. Post-cannulation bleeding
