Chapter 9 ABDOMINAL VASCULATURE
An AAA is present when the diameter of the abdominal aorta exceeds:
3 cm
Which of the following statement about the IVC is not true? A. The diameter of the IVC is variable B. Respiration can affect the size of the IVC C. The IVC is located to the left of the abdominal aorta D. The IVC is considered retroperitoneal in location
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
What flow pattern would the postprandial SMA yield in a small bowel ischemia?
high resistance
The left gonadal vein drains directly into the:
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?
celiac artery
