Ch. 9 Vascular Quiz Flashcards
_________ is the largest artery in the abdomen.
aorta
The aorta increases with age. (T/F)
true
The first anterior branch of the aorta is __________.
celiac axis
The lateral branches off the aorta just below the SMA are __________.
renal arteries
Name one limitation that can occur while scanning the aorta & what can be done about it.
bowel gas; move the transducer to the left and angle to the midline
What is the most accurate measurement when documenting an AAA?
AP transverse
Name a landmark that helps us determine where to measure the aorta at each location:
Prox ________________
Mid ________________
Distal ________________
Prox = left lobe of the liver/esophageal junction Mid = below the SMA, above the renal arteries Distal = above bifurcation
Name two clinical indications for an aorta exam.
abdominal pain radiating to the back, pulsating abdominal mass
When is surgery considered for a AAA, what measurment?
over 5 cm
Why is it important to document the relationship between a AAA and the renal arteries?
pressure on the renal arteries could restrict blood flow to kidneys causing ischemia
At what size do we consinder an enlarged portion of the aorta a AAA?
increase in diameter of greater than 1.5 times its normal
The portal vein is formed by _________________ vessels and carries ___________ rich blood to the liver.
SMV, IMV, splenic vein; nutrient
Name two reasons we use Doppler when evaluating vessels. (What info. we gather from Doppler)
presence of flow and direction of flow
The SMA waveform changes depending on the patient status, fasting vs. non-fasting. Please describe the waveform for each.
Fasting: high resistive, low end diastolic
Non-fasting: low resistive, high end diastolic
Thrombosis of the hepatic vein is called
budd-chiari syndrome
