Name 3 things Veins do for our bodies
Carry deoxygenated blood, Store blood, Thermoregulate
Where are Deep Veins found?
Muscular compartments, below the fascia
Where are Superficial Veins?
Above the fascia, close to the skin
What are the 3 different types of veins?
Deep, Superficial, Perforating
Where can perforating veins be found?
connecting deep to superficial veins
What is the term for when two veins come together?
Junction or confluence
What is the superficial vein that runs the length of the thigh?
Great Saphenous Vein (GSV)
What position should a patient be placed in bed for optimal scanning?
Reversed Trendelenburg
What is a secondary position that can be used for optimal scanning?
Semi-Fowler
What other two factors can you as a technologist mediate in order to assist in vein dilation?
- Keeping the patient warm (vein dilation)
- Keeping the patient relaxed (Tension = vasoconstriction)
What is the term meaning “toward the head”?

What is a valve?
an inward projection of the intimal layer of a vein wall producing two semilunar leaflets that prevent the retrograde movement of blood flow
What was the name of the study, before ultrasound technology, used to look at veins?
Venography
What is a major risk of venous duplex imaging?
It is extremely examiner-dependent
What three things is the examiner trying to assess using venous duplex ultrasound?
- the presence or absence of thrombus
- The risk of the thrombus dislodging and traveling to the lungs
- The competence of the contained valves
What are the freeways of the venous system?
the deep veins
