Chapter 11 Abdominal Doppler

Question 0

What is the appropriate probe for aortic scan/Doppler?

Answer 0

3. 5 MHz

2. 5 MHz for large difficult patients

Question 1

What are the 2 basic patient positions for abdominal scanning?

Answer 1

1. Midline approach

2. Side flank approach

Question 2

What are the probe choices for aortic scans?

Answer 2

1. Curved linear

2. Phased array

Question 3

How is the right renal positioned anatomically and off the AO?

Answer 3

1. Anatomically anterolaterally

2. 10 o clock

Question 4

How is the Left Renal positioned anatomically and off the AO?

Answer 4

1. Posterolateral

2. 4:00 position

Question 5

What is the Doppler character for suprasternal aorta?

Answer 5

Monphasic due to low resistance bed.

Question 6

What is the Doppler character of the infra renal aorta?

Answer 6

Multiphasic due to higher resistance beds. Also similar to LE arteries

Question 7

Suprarenal refers to:

Answer 7

Proximal AO and is part of the distal bed

Question 8

Infra renal refers to:

Answer 8

Distal To renal arteries

Question 9

What arteries are assessed in abdominal Doppler

Answer 9

Supra renal
Infra renal
Celiac trunk

Question 10

Flow character in all branches tend to have the same as an ICA
Because?

Answer 10

They all perfuse organs with low resistance

Question 11

Renal arteries divide into what 5 segmental arteries?

Answer 11

Hilum&raquo_space;> renal pyramids&raquo_space;> interlobular arteries&raquo_space;> arcuate arteries&raquo_space;> interlobar arteries

Question 12

What is the normal length for a kidney?

Answer 12

9 to 12 cm

Less than 9 suggest renal failure

Question 13

What 2 different approaches are used to measure the kidneys?

Answer 13

1. Posterolateral (levels)

2. Anterolateral (tilts)

Question 14

Describe the banana peel view?

Answer 14

Peel view of the aorta along with renal origins on the same plane. The right will be anterior 10:00 and the left will be more posterior 4:00.

Question 15

What are we looking for in Hilum color doppler?

Answer 15

1. Early systolic peak (ESP)

2. Rapid acceleration time (rise time)

Question 16

A Postprandial patient refers to what?

Answer 16

Patient being scanned after a meal

Question 17

Which study would have less diastolic flow in the SMA. Fasting patient or a postprandial patient? And why

Answer 17

Fasting patient will have less flow because the intestine requires less perfusion in a fasting state.

Question 18

What are 3 Doppler waveforms from the flank approach?

Answer 18

1. The distal renal artery
2. The Hilum
3. The renal parenchyma

Question 19

In renal artery Doppler where do we drop our angle box?

Answer 19

1. 1-2 cm from the kidney
2. 2-3 cm proximal to that
3. Measure only PSV

Question 20

What does parenchyma refer too?

Answer 20

Organ tissue getting within the kidney.

Question 21

After a patient eats (________ state) the intestine becomes active and requires more ________.

Answer 21

Postprandial and perfusion

Question 22

The loss of diastolic flow in a postprandial superior Mesenteric artery may suggest _______ or _______.

Answer 22

Distal stenosis or occlusion.

Question 23

The loss in Doppler character w/I the kidney parachyma suggest _______ or ________.

Answer 23

Renal disease or causing organ failure
