Week 12 B

Question 1

What qualifies as an abnormal BCV?

Answer 1

• Non-phasic / Non- pulsatile
• Low velocity = partial or Total occlusion
• Retrograde flow in IJV or SCV = BCV obstruction

Question 2

An obstruction in the BCV will result in retrograde flow where?

Answer 2

IJV or SCV

Question 3

An IJV obstruction will result in what collaterals?

Answer 3

Facial V or Superior Thyroid V

Question 4

A BCV occlusion will result in what collaterals?

Answer 4

EJV with AJV, or IJV

Question 5

A Prox. SCV occlusion will result in what collaterals?

Answer 5

Thyrocervical Trunk

Question 6

A Dist. SCV occlusion will result in what collaterals?

Answer 6

Thoracic V or Cephalic V

Question 7

Thrombus in UE veins is identified with what properties?

Answer 7

• Incompressibility
• Lack of Color
• No Doppler within Thrombus
• Collaterals Seen

Question 8

Thrombus resulting in occlusion will have what properties in UE veins?

Answer 8

• No Color Flow

- Doppler distal = No pulsatility / No phasicity

Question 9
