URR AO & IVC

The iliac arteries originate:

• At the level of the kidneys

• At the level of the symphysis pubis

• At the level of the umbilicus

• At the level of the inguinal ligament

How can you demonstrate a longitudinal view of the aorta and IVC on the same image?

• Use a coronal view with decubitus patient positioning

• Use a transverse view with decubitus patient positioning

• Use a transverse view with supine patient positioning

• Use a longitudinal view with supine patient positioning

The AP dimensions of the aorta:

• Are most accurately measured in the transverse plane

• Are most accurately measured with color Doppler activated

• Are most accurately measured with the sound beam parallel to the aorta

• Are most accurately measured with a longitudinal plane

What changes occur in the normal aortic flow as it moves from the diaphragm to the legs?

• The resistance to the flow increases as you move toward the extremities

• The resistance to the flow decreases as you move toward the extremities

• The flow pattern changes from triphasic to biphasic

• The flow pattern demonstrates more antegrade diastolic flow as you move toward the extremities

An abdominal aortic aneurysm is diagnosed when the diameter exceeds:

• 4 cm

• 3 cm

• 2.5 cm

• 3.5 cm

What is the most common complication of an aortic aneurysm?

• Rupture

• Dissection

• System HTN

• Ischemia of the legs

The yin-yang sign on color Doppler evaluation is related to what aortic abnormality?

• Dissection

• Coarctation

• Aneurysm

• Bovine arch

Anemia and low hematocrit levels can be indicator for

• Slow leak of an AAA

• Dissection

• Leriche Syndrome

• Ormond disease

Identifying which two structures guarantees a complete evaluation of the abdominal aorta?

• Coronary arteries and iliac arteries

• Celiac axis and iliac arteries

• Superior and inferior mesenteric arteries

• Hepatic and splenic arteries

What is a hallmark sonographic sign of an endoleak in an aortic graft?

• Increase in aortic sac size

• Changes in echogenicity of the graft

• Increase in aortic lumen size

• Abdomen pain while scanning
