Flashcards in Venous Test Q&A Deck (34):
1

Jugular vein can be compressed with transducer pressure from skin. True or false

True

2

Purpose of superficial vein mapping to determine the veins ability to bypass conduit. True or false

True

used for coronary artery bypass pg 237

3

Purpose of venous reflux testing is see if venous is competent.  True or false

False, to test for incompentacy

pg 137

4

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)

5

Three factors of the Virchow's triad

Circulatory stasis

Hypercoagulable state

Endothelial (vein wall) injury

pg 111

6

What is the longest vein in the body?

Greater spahenous vein

7

Most important for ruling out DVT

Compression

8

What is the time when identifying vein reflux?

Deep veins > 1 sec

GSV, SSV > 0.5 sec

Perforating veins > 0.35sec

pg 138

9

Is superficial femoral vein deep or superficial?

deep 

pg 97

10

What plane is best to use for vein duplex imaging?

longitudinal

(quizlet)

11

What are the risk factors for DVT?

  • post operative state
  • previous DVT
  • cancer
  • thrombophilia
  • trauma
  • pregnancy

  • (pg 111 and beths powerpoint)

12

Which veins have valves and which do not

Dodd's and Hunterian are thigh perforators

(powerpoint)

16

When is adequate pressure applied to compress a vein?

When the companion artery is deformed

(quizlet)

17

Which veins are pulsatile?

internal jugular, subclavian, innominate, axillary

(powerpoint and pg 105)

18

Compression technique is not used when?

When a free-floating clot is present

pg 124

What is the lethal complication of acute DVT?

Pulmonary embolisom

(powerpoint)

Signs and symptoms of acute DVT

(powerpoint)

 

21

In the presents of incompetent valves, what does distal aug produce?

flow above the baseline

22

Identify deep veins

deep arm veins: superior vena cava, innominate, subclavian, axillary, brachial, radial, and unlar

deep leg veins: IVC, CIV, IIV, EIV, common fem, femoral, deep femoral vein, pop vein, anterior tibials, posterior tibials, abd peroneal

Chronic DVT

Implies thrombus is at least several months old

increased echogenicity

vein is contracted

may be so contracted that it may not be apparent on ultrasound

34

DVT annual estimates
