Lesser saphenous is now called?

Answer 13

Small saphenous

Question 14

Why was it necessary to change the name of long and lesser saphenous?

Answer 14

Confusion b/c of similar abbreviations of LS

Question 15

Answer 18

1. Fascia border
2. Drains into soleus muscle
3. Where you find the posterior tibials

Question 19

What is the interosseous septum?

Answer 19

1. Fascia between the bones
2. Defines back interior compartment
3. Landmark for anterior tibials

Question 20

3 reasons to scan the saphenous vein?

Answer 20

1. Assess for thrombis
2. Evaluate the veins
3. Look for reflux

Question 21

What is the probe preference for saph study?

Answer 21

7-10 mHz

Question 22

What are the 6 characteristics you can assess listening to a vein?

Answer 22

1. Patency
2. Spontaneity
3. Phasicity
4. Nonpulsatility
5. Augmentation
6. Competence

Question 23

Define patency?

Answer 23

Vessel is open and flowing

Question 24

Define Spontaneity

Answer 24

Normal characteristic w/o resorting to compressions to bring flow signal.

Question 25

Define phasicity?

Answer 25

Signal rises and falls in phase with respiration

Question 26

Inspiration does what to venous flow?

Answer 26

Increases abdominal pressure which brings less flow from legs through IVC.

Question 27

What does expiration do to venous flow?

Answer 27

Decreases abdominal pressure where flow resumes on Doppler display.

Question 28

Define non pulsatility?

Answer 28

1. Non elevated R Heart pressure 2. Fluid overload increasing central venous pressure 3. More resistance to flow

Question 29

Define augmentation?

Answer 29

Increase flow from compression distal to probe Obstruction will abolish/diminish augmentation

Question 30

Define competence?

Answer 30

1. Normal flow showing valves working | 2. Flow that stops with proximal compression resulting in no reflux

Question 31

Good compression doesn't rule out.....

Answer 31

1. Nonocclusive thrombis | 2. Isolated calf clots
