Arcuate ligament syndrome
Evaluation of abdominal aortic aneurysm is facilitated if the study is done:
After lunch but before dinner
After breakfast but before lunch
This study does not depend on patient preparation
What is the first major branch arising from the abdominal aorta?
Right renal artery
Left renal artery
What is the most common location for AAA?
At the level of the SMA

Thrombus extension from DVT in the legs
Tumor extension from renal cell carcinoma
What shape are most aortic aneurysms?
Patients being evaluated for portal hypertension may have liver dysfunction symptoms including all of the following except
A 65 year old male presents to the vascular lab for evaluation of the abdomen after involvement in a car accident. During the duplex exam, an asymmetric outpouching is identified in the mid to distal aorta. What are these findings most consistent with?
The abdominal aorta is considered aneurysmal when the diameter measures greater than what?
A patient has a 7 cm abdominal aortic aneurysm. The patient elects not to have an operation, despite the surgeon's recommendation. Which of the following is false?
The risk of death from cardiac disease is greater than the risk of death from rupture of the aneurysm
There is little risk for aortic occlusion
The surgeon's recommendation is sound based on the natural history of AAA
There is little risk for distal embolization
The mortality of rupture, even with prompt care, is at least 50%
On sonographic evaluation, which of the following describes the appearance of an IVC filter?
Hyperechoic, circular rings within the ICV lumen
Echogenic lines that converge to a point
Hypoechoic lines that converge to a point
Hypoechoic, circular rings within the IVC lumen
Your measurement of a patient's abdominal aorta gives a diameter of 6.5cm. the probable management of this patient would likely involve:
Follow-up scan in one year
No course of action; this finding is within normal limits
Demonstration of vein wall coaptation of the subclavian vein is best performed with:
Firm arm compression
The subclavian vein cannot be assessed for vein wall coaptation
The patient taking a quick, deep breath
The abdominal vessel that is most commonly compromised by compression of the median arcuate ligament of the diaphragm is the:
LT gastric artery
None of the above

Patients with significant mesenteric artery obstructive disease generally have symptoms of:
Preprandial pain, relieve by eating
Preprandial bloating, relieved by eating
Postprandial hypertensive state
Because of the abdominal pain associated with chronic mesenteric ischemia, patients often experience which of the following?
Overeating and weight gain
Fear of exercise
Nausea and vomitting
Fear of food and weight loss

Free of discernable symptoms
Where does the left sided IVC in a duplicate system typically terminate?
Right renal vein
Left renal vein
To evaluate blood flow within the splanchnic arteries, you should examine the following vessels:

All of the above
What is a filter placement in the IVC designed to prevent?
