RVT ARDMS EXAM REVIEW
How do you decrease risk for venous stasis? - ANSWERS--limiting
long periods of inactivity or bed rest, promoting venous drainage
when inactive
-leg elevation
-support stockings
-pneumatic compression devices
-weight management
What are varicose veins? - ANSWERS-Enlarged veins that appear as
purple or blue and may appear twisted and/or bulging near skin
surface.
-very small varicosities,"spider veins(telangiectasias)", usually not
medically significant.
-large veins may be painful and/or symptomatic of venous disease
leading to serious venous complication.
What causes varicose veins? - ANSWERS-1. Chronic ambulatory
venous hypertension, or high pressure in veins due to loss of valve
function or obstruction.
2. Pregnancy (increased blood volume along with increased
abdominal pressure).
3. Heredity
4. Prolonged standing(pressure in legs remains elevated for long
periods of time).
, 5. Trauma
6. Age (when veins lose Thierry elasticity and more easily stretch,
allow blood to pool).
7. Obesity May be considered
Most common cause of varicose veins? - ANSWERS-Incompetence
of the greater saphenous vein
What is venous ablation? - ANSWERS-Uses heat energy to close off
the diseases vein.
-if cannot be performed microphlebectomy, the surgical removal of
the diseases vein, may be considered
What is sclerotheraphy? - ANSWERS-The injection of a sclerosing
solution, an irratant, into the vessel, resulting in its closure
-larger veins may be treated with this but foam sclerotheraphy is more
successful.
What is foam sclerotheraphy? - ANSWERS-A solution is injected as a
foam instead of a liquid.
Advantages of foam sclerotheraphy? - ANSWERS-1. Better
visualization while it spreads through targeted veins
2. Ability to use smaller amounts of solution
3. Better contact inside the veins due to the foam medium (it stays
longer and is not diluted by mixing with blood inside vein.)
