Q

Virchow’s triangle can be used to determine:

A

the presence of thrombus

17
Q

DVT is the primary disease that fals under:

A

VTE

18
Q

What is a result of damage from chronic DVT:

A

PTS

19
Q

duplex ultrasound, computed temgraphy (CTV), magnetic resonance venography (MRV) are all part of:

A

diagnostic imaging

20
Q

venography and Intravascular Ultrasound (IVUS) are part of:

A

Intraprocedural imaging

21
Q

T or F: If the vein can be compressed using duplex ultrasound, there is no DVT present

A

True

22
Q

What ultrasound can differientate acute from chronic disease?

A

CTV

23
Q

Often used when duplex ultrasound is inconclusive. Commonly used to view adominal/pelvic area in 3D image and has the ability to obtain blood flow information:

A

MRV

24
Q

Similar to arterial angioplasty. X-ray that uses contrast to help place devices and guide treatment:

A

Venography

25
Q

Used to access presence and extent of disease, examine lesion geometry and morphology, and position guidewire and stent:

A

IVUS

26
Q

Viewing on IVUS, when placing a stent, you take the avg min and max diameters and oversize by:

A

1-2 mm

27
Q

Imaging falls under 2 main categories:

A
  • diagnostic
  • intraprocedural
28
Q

______ is particulary useful to evaluate lesion severity and for accurate stent placement.

A

IVUS

29
Q

Describe what may0thurner syndrome looks like on a MRV image

A

vein is compressed and the outflow in obstructed blood flow is redistributed and collaterals are activated and/or formed

30
Q

What is the main takeaway of the VIDIO trial?

A

IVUS is more effective at visualizing venous disease than venography

31
Q

the Venovo™ Venous Stent System IFU recommends oversizing by how much?

A

1 – 3 mm

32
Q

True or False: Venography is used for both diagnostic and intraprocedural imaging.

A

True

33
Q

Which of the following is a negative aspect of venography?

A

High radiation

34
Q

Which of the following is a positive aspect of IVUS?

A

All of the above
