Venous Test Q&A Flashcards
Jugular vein can be compressed with transducer pressure from skin. True or false
True
Purpose of superficial vein mapping to determine the veins ability to bypass conduit. True or false
True
used for coronary artery bypass pg 237
Purpose of venous reflux testing is see if venous is competent. True or false
False, to test for incompentacy
pg 137
What is difficult to compress during duplex imaging?
clotted veins (pg 123)
arm veins such as innominate, subclavian, and proximal axillary due to proximity to the clavicle (pg 151)
At the level of the adductor canal, femoral vein difficult to compress due to depth of vessel and proximity of femur (pg 15)
The biceps femoris tendon may prevent compression of distal popliteal (pg 116)
Three factors of the Virchow’s triad
Circulatory stasis
Hypercoagulable state
Endothelial (vein wall) injury
pg 111
What is the longest vein in the body?
Greater spahenous vein
Most important for ruling out DVT
Compression
What is the time when identifying vein reflux?
Deep veins > 1 sec
GSV, SSV > 0.5 sec
Perforating veins > 0.35sec
pg 138
Is superficial femoral vein deep or superficial?
deep
pg 97
What plane is best to use for vein duplex imaging?
longitudinal
(quizlet)
What are the risk factors for DVT?
- post operative state
- previous DVT
- cancer
- thrombophilia
- trauma
- pregnancy
- high dose estrogen RX
- “economy class syndrome”
- Bed rest > 4 days
- lower limb paralysis
- (pg 111 and beths powerpoint)
Which veins have valves and which do not
No valves: IVC, common iliac vein, and external iliac vein (in most)
Valves: femoral 4, pop 2, PTV 10, per 10, ATV 10
pg 136
CFV lies in what canal
groin crease
pg 97
Is the basilic vein deep or superficial?
superficial
pg 149
Perforators from GSV are what?
Cockett’s are ankle perforators
Sherman’s and Boyd’s are knee perforators
Dodd’s and Hunterian are thigh perforators
