Q

Why is thrombosis in the UEVs now more common?

A

B/c there is an increase in injury to the vein walls, due to frequent intro of needles + catheters into arm veins

Q

What is the pt prep + positioning for a UEV exam?

A

-Clothing + jewelry around arm removed
-Pt gown provided
-When imaging the subclavian + jugular veins, the bed must be flat with arm at side + head turned in opposite direction
-Imaging reset of veins can be done with bed flat or with head elevated
-The arm may be abducted to allow access to view the axillary vein

Q

Can we compress the brachiocephalic vein?

A

No

17
Q

Which vein terminates into the subclavian vein?

A

The cephalic vein

18
Q

The subclavian vein becomes the ___ vein?

A

Axillary

19
Q

Because we can not compress the subclavian vein due to the clavicle, what other maneuver can be performed?

A

The sniff test - this quick inspiration should cause the vein to collapse

20
Q

What are the 2 main superficial UEVs?

A

Cephalic + basilic (use high frequency)

21
Q

We use a mid-frequency linear probe for which UEVs?

A

IJV, brachiocephalic, subclavian, axillary + brachial veins

22
Q

What is the median cubital vein?

A

A vein that connects the cephalic + basilic veins at the antecubital fossa

23
Q

Why is the MCV a common site for thrombus?

A

B/c it is used for venipuncture

24
Q

The axillary vein begins at the junction of the ___ + ___ veins?

A

Cephalic + subclavian

25
Q

The basilic vein terminates into the ___ vein along the medial part of upper arm?

A

Axillary

26
Q

Which vein is m/c a bifid system (meaning duplicated)?

A

The brachial vein

27
Q

The brachial veins are formed at what level?

A

Level of antecubital fossa (by junction of 2 radial + ulnar veins)

28
Q

Which veins are very small + not often a site for venous thrombosis?

A

Radial veins (they are technically deep veins, but are not in the routine exam)

29
Q

Are the ulnar veins normally examined?

A

No

30
Q

Why is the basilic vein a common site for thrombosis?

A

B/c commonly used for PICC lines

31
Q

Will an acute or chronic DVT appear contracted?

A

Chronic

32
Q

Will an acute or chronic DVT appear dilated?

A

Acute

33
Q

Which UEVs have normal pulsatile flow due to the close proximity to the heart?

A

The IJV, brachiocephalic + subclavian veins

34
Q

If both subclavian veins have non-pulsatile continuous flow, what disease should be suspected?

A

SVC disease

35
Q

How would the PW appear in partially thrombosed veins?

A

Continuous with augmentation with distal compression

36
Q

SF of a catheter?

A

Bright, straight, parallel echoes

37
Q

What is the m/c treatment for a DVT?

A

Anticoagulation
