11 describe the waveform characteristics of the arterial side of an
arteriovenous fistula: the waveform of the arterial side of an arteriovenous fistula
demonstrates an abnormally low resistive arterial flow pattern. This means a
waveform with increased and sustained diastolic flow.
12. Describe the waveform characteristics of the venous side of an
arteriovenous fistula: the venous side of an arteriovenous fistula demonstrates a
waveform with increased velocity, pulsatility and with spectral broadening due to
turbulence.
13. List 4 sonographic criteria for determining renal artery stenosis: 1.
Kidney size less than 9 cm in length
2. Peak main renal artery velocity > 180 cm/sec
, .
3. Renal artery/aorta ratio > 3.5
4. Intrarenal parvus tardus waveform
14. Describe the sonographic appearance of a ureterocele: round, cystic
structures that project into the bladder lumen at the ureterovesical junction
15. Name the structure that connects the apex of the bladder to the umbilicus-
: median umbilical ligament ( urachus)
16. What is the term that describes cystic dilatation of the median umbilical
ligament (urachus): urachal cyst - seen as an echo-free tubular structure in the
lower abdomen that extends from the umbilicus to the dome of the bladder
17. What object is placed in the ivc to prevent the ascension of lower extremity
thrombus into the lungs?: greenfield filter
18. What role can ultrasound play in the evaluation of the greenfield filter?:
can determine location
19. Trace the sequence of branching renal arteries from the aorta to the renal
capsule: main renal artery segmental arteries interlobar arteries arcuate
arteries interlobar arteries
20. Which arteries of the kidneys are positioned between the medullary
pyramids?: interlobar arteries
