WITH COMPLETE SOLUTIONS
Which vessel does the axillary vein drain? Correct Answer: Subclavian
Which vessel does the common anterior tibial vein drain into? Correct Answer:
Popliteal
A venous Photoplethysmographic study (PPG) is ordered on your next patient. The
initial refill time (VRT) is 13 seconds with a VRT of 15 seconds following
application of a tourniquet. What do these values suggest? Correct Answer:
Incompetence of the deep system
How is flow to the upper extremity affected when a patient with acute superior
vena cava syndrome takes in a breath? Correct Answer: The flow remains the
same
How is the left renal vein anatomically related to the aorta? Correct Answer: The
vein is anterior to the artery
During muscle contraction, what is the normal direction of blood flow in the
perforating veins of the lower extremity? Correct Answer: Moves cephalad from
the superficial into the deep
Mrs. CS is complaining of swelling of her left lower extremity. As you proceed
with your venous duplex study, you document continuous flow in the left common
femoral vein. How would you most likely interpret that finding? Correct Answer:
Indicative of a proximal obstruction
During a CW Doppler evaluation of a swollen right lower extremity, you are not
able to discern a spontaneous signal at the PTV site. However, you can document
augmentation with distal compression. What is the significiance of these findings
in the PTV? Correct Answer: Within normal limits
A venous duplex study is ordered on a pt with a swollen right arm 4 days after the
insertion of a PICC line. If that line was inserted into the cephalic vin (V), what is
the most likely course it will follow? Correct Answer: Cephalic V into subclavian
V into Innominate V
, What is the most likely reason that a patient might have pulsatile flow in the
common femoral veins? Correct Answer: The patient's hx of congestive heart
failure explains this finding.
Which of the following statements about the portal vein (PV) is the least accurate?
Correct Answer: The PV carries approximately 30% of the blood flow into the
liver.
What is the most likely venous pressure measured at the ankle level of a supine
patient? Correct Answer: 15mm Hg
You detected a thrombosed femoral vein on your pt, Mrs. GH. Within the vessel
lumen, you are able to document areas of cephalad flow and two linear structures
that are brightly echoic. What are these findings most likely consistent with?
Correct Answer: Recanalization
Your next patient has an APG study ordered. During that procedure you calculate
ejection fraction which measures calf muscle pump function. What percentage of
blood should be ejected for calf muscle pump function to be effective? Correct
Answer: >60%
Your next pt is the star pitcher on your alumni's baseball team, a previously healthy
18 year old with recent onset of pain and swelling of his right upper extremity.
What is the most likely cause of his problem? Correct Answer: Paget-Schroetter
Syndrome
Your venous duplex study documents spontaneous, phasic flow in the femoral vein
which is displayed below the baseline. As you manually compress the external
ilian vein just above the inguinal ligament, flow is above the baseline. What is the
significance of that finding? Correct Answer: This signifies venous reflux
What is the expected flow pattern in the hepatic vein? Correct Answer:
Hepatofugal (flow away from liver)
Mr. LM, is complaining of a 6 month hx of swelling in his left lower extremity
with increasing discomfort, not exactly pain, but a heaviness. What is the most
likely cause of his signs/symptoms (S/S)? Correct Answer: Incompetent venous
valves
