COMPREHENSIVE QUESTIONS AND
ACCURATE SOLUTIONS VERIFIED
◉ Arterial flow proximal to an AV fistula will be ___.
A. low resistance
B. phasic
C. high resistance
D. laminar. Answer: A. low resistance
◉ A 55yo with hx of alcoholism, jaundice and cirrhosis is referred for a
liver doppler exam. Which of the following is an expected abnormal
finding?
A. respiratory phasicity in portal vein flow
B. multiphase flow in the hepatic veins
C. dilated IVC
D. increased resistance in the hepatic artery. Answer: D. increased
resistance in the hepatic artery
Resistance in the hepatic artery will increase with the increase in
resistance to flow in the cirrhotic liver tissue. The coronary vein (a.k.a.
left gastric vein) and the umbilical vein will dilate with significant portal
HTN. The IVC is not usually affected by isolated cirrhosis. Hepatic vein
flow will be multiphasic in the normal patient. Normal portal venous
flow will demonstrate mild respiratory phasicity.
, ◉ A patient's carotid exam demonstrates 50-69% stenosis. What will be
the recommended treatment for this patient?
A. 6mo F/U exam
B. angiography
C. endarterectomy
D. stent. Answer: A. 6mo F/U exam
◉ You are performing a follow up exam on a synthetic fem-pop graft
that is 2 weeks post-op. The native arteries and graft appear normal on
the 2D and color doppler evaluation. These same segments were
evaluated using PW doppler and monophasic waveforms with mild
diastolic flow throughout the cardiac cycle are demonstrated. Which of
the following is the most likely reason for the discrepancy in findings?
A. mid graft thrombosis
B. reactive hyperemia
C. collateral formation
D. stenosis distal to the graft. Answer: B. reactive hyperemia
Reactive hyperemia is the transient increase in blood flow that occurs
after a period of ischemia. It commonly occurs following the removal of
a tourniquet, unclamping an artery during surgery, bypass graft
placement or after vessel recanalization caused by a device or
medication. Monophasic flow with increased diastolic flow may still be
identifiied in the first 1-2 months after the procedure due to reactive
hyperemia. The body needs time to adjust to the new flow pattern. The
waveform should return to a triphasic pattern after 2 months post-op.
