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

Identify velocity values that suggest severe stenosis of the mesenteric vessels.

Discuss examination technique to differentiate between celiac compression versus stenosis.

Determine symptoms of ischemic bowel disease.

Which velocity suggests greater than 70% stenosis of the superior mesenteric artery?

A. 100 cm/s

B. 180 cm/s

C. 200 cm/s

D. 275 cm/s

How can a sonographer try to differentiate between celiac compression and stenosis?

A. Use color Doppler

B. Document velocities during inspiration and expiration

C. Evaluate the vessel in the transverse scan plane

D. Scan the patient in a sitting position

Which part of the patient history was suggestive of ischemic bowel disease?

A. Elevated liver function tests

B. Cholelithiasis

C. Postprandial abdominal pain

D. Peripheral vascular disease

What is the velocity criterion for greater than 70% stenosis of the celiac artery?

A. 98 cm/s

B. 105 cm/s

C. 142 cm/s

D. 200 cm/s
