You scanned a pt who complained of a fear of eating, and severe post prandial abd pain that has
lasted for years.
Image A is the 2-D scan you took of her celiac trunk, and image B is the Doppler you obtained of
its peak systole. Image C is what you obtained distally, in a hepatic artery in her left liver.
Obstruction of flow in the celiac artery and tarsus parvus intrahepatic ally
You obtained this spectrum in an arcuate artery of Mr Boot's transplant kidney a few hours post
surgery. What is a likely explanation of this arcuate artery Doppler?

A patient has been referred for a Doppler study with symptoms of chronic mesenteric ischemia.

The measurement of peak systole of the aorta contributes to the computation of __________ in
the assessment of patients for renal artery stenosis
RAR
, Formula for RI
PSV-EDV/PSV
In the assessment of renal artery stenosis what is the direct method?
renal artery peak systolic velocity (RPSV) and the aortic peak systolic velocity to determine the
maximal RPSV and the renal aortic ratio (RAR)
In assessments of renal artery stenosis what is the indirect method?
evaluation of the segmental or interlobar arteries within the kidney. This technique infers
stenosis of the main renal artery through recognition of alterations of the normal waveform
shape obtained from the intrarenal arteries.
What is the most common cause of renal artery stenosis in younger women?
fibromuscular disease
What type of resistance does does the SMA have while fasting?
high resistance while fasting, low after a meal
What area of TIPS is most likely to develop in a stenosis?
Distal portion at IVC
