C. The IVC is located to the left of the abdominal aorta

The first main visceral branch of the abdominal aorta is the:

Celiac artery

What vessel may attach to the splenic vein before reaching the portal confluence?

Inferior mesenteric vein

What vessel travels directly anterior to the left renal artery?

Left renal vein

A disorder of the connective tissue characterized by tall stature and aortic and mitral valve insufficiency is:

Marfan syndrome

An aneurysm associated with infection is termed

Mycotic

In the sagittal plane, you recognize a circular, anechoic vascular structure posterior to the IVC. Which of the following would this structure be most likely?

Right renal artery

Enlargement of the IVC, with subsequent enlargement of the hepatic veins, is seen in cases of

Right sided heart failure

Which of the following vessels would most likely yield a high-resistance flow pattern?

fasting SMA

The hepatic artery should demonstrate:

low resistance

Clinical findings of an AAA include all of the following:

pulsatile abdominal mass abdominal bruit back pain abdominal pain lower extremity pain

The IVC and the abdominal aorta are intra/retro peritoneal?

retroperitoneal

The IVC terminates at the:

right atrium

What vessel is shortest in length?

right renal vein

The inner wall layer of a vessel, closest to the passing blood, is the:

tunica intima

Which of the following would most likely yield a high-resistance flow pattern? A. celiac artery B. Common iliac artery C. Splenic artery D. Right renal artery

B. Common iliac artery

Occlusion of the hepatic veins describes:

Budd-Chiari syndrome

The aorta originates at the:

left ventricle

A patient presents with unexplained abdominal pain for vascular assessment of the SMA. Sonographically, you note that the patient's SMA yields a persistent high-resistive flow patter. This is indicative of:

small bowel ischemia

Which vascular structure may be confused for the main pancreatic duct?

splenic artery

The outer wall layer of a vessel is the:

tunica adventitia

The diameter of the IVC should never exceed:

2.5cm

What vessel can be often noted coursing between the SMA and the abdominal aorta in the transverse scan plane?

Left renal vein

What should the postprandial flow pattern be within the SMA?

Low resistance

The second main branch of the abdominal aorta is the:

SMA

Which of the following vessels show a different flow pattering after eating?

SMA

What abnormality would the failure of an EVAR to isolate an aneurysm from circulation most likely results in?

endoleak

The most common shape of an AAA is:

fusiform

The veins seen attaching to the IVC just below the diaphragm are the:

hepatic veins

left renal vein

Which of the following is not a section of the IVC?

pancreatic

What branch and its tributaries of the abdominal aorta appears as a "seagull" in the transverse plane?
