Q

What are some tips to find TRANS LT/RT FV MID

A
  1. Take this image when the probe is halfway between the inguinal crease and the knee
  2. You may also observe that this is the area just proximal to where the vein dives entering the adductor canal

Q

What are some tips to finding the TRANS RT/LT FV DIST?

A
  1. take this image when the probe is just proximal to the medial condyle of the knee.
  2. Use either the anterior or posterior window
  3. Anterior window uses the muscle as a window to visualize the vessels
  4. Angling the probe slightly towards the patients head can help get perpendicular

Q

What is the acceptable annotation for getting the transverse popliteal vein in 2D?

A

TRANS RT/ LT POP V

19
Q

What are some tips to getting the transverse image of the popliteal?

A
  1. Place probe in the crease behind the knee (this will make the vein more superficial than the artery)
  2. Interrogate proximally to try overlapping the distal FV and distally to evaluate the tibial peroneal trunk
20
Q

What is the acceptable annotation for a sagittal image of the common femoral vein?

A

SAG RT/ LT CFV

21
Q

What are some tips to getting the sagittal common femoral vein?

A
  1. take the image above where the GSV dumps into the CFV
  2. The angle of the vessel will usually slope upwards from left to right on the screen.
  3. Angle the color box parallel to this
  4. Adjust the colour gain and scale accordingly
22
Q

What is an acceptable annotation for getting a spectral image of the CFV?

A

SAG RT/LT CFV

23
Q

What are some tips to getting the spectral image of the CFV? Is an augment required? What do we access for?

A
  1. All spectral image will use the same window as the colour image.
  2. An augmentation is not required
  3. access for direction, spontaneity and phasicity
24
Q

What is an acceptable annotation for sagittal GSV colour image?

A

SAG RT/LT GSV

25
Q

What are some tips in getting the SAG RT/LT GSV with colour? 2

A
  1. Slide the transducer medially while rotating counter- clockwise slightly
  2. pay attention to the colour scale as flow in the GSV is typically slower than the CFV
26
Q

What is the acceptable annotation for the profunda vein with color?

A

RT/LT prof V

27
Q

what are some tips to getting the profunda vein with color? 3

A
  1. Located approximately 2-3 cm distal to the GSV/ CFV confluence
  2. profunda vein should drop straight off the bottom of the CFV and course with the FA
  3. Find the blue pants
28
Q

What is the acceptable annotation for the sagittal femoral vein proximal with color?

A

SAG RT/LT FV PROX

29
Q

What are some tips to getting the sagittal femoral vein proximal with color? 3

A
  1. Taken a few cm from the profunda confluence
  2. Use the artery as a guide to ensure that you are on the vein
  3. blood filled artery acts as a window
30
Q

What is the acceptable annotation for the sagittal femoral vein proximal spectral image?

A

SAG RT/LT FV PROX/ AUG

31
Q

What are some tips to finding the sagittal femoral proximal spectral image?

A
  1. May need to reposition your body to perform proper augmentation of the vessel
  2. Augmentation should be shown after spontaneous, respirophasic flow and should alias
32
Q

What is the acceptable annotation for a sagittal femoral vein middle colour image?

A

SAG RT/LT FV MID

33
Q

What are some tips to finding the sagittal femoral vein middle color image?

A
  1. Take this image when the probe is halfway between the inguinal crease and the knee

Q

What is the acceptable annotation for the sagittal femoral middle spectral image?

A

SAG RT/LT FV MID/AUG

35
Q

What are some tips to finding the FV mid spectral? Augmentations should be shown to have what?

A
  1. May have to reposition your body to perform proper augmentation of the vessel
  2. Augmentations should be shown after spontaneous, respirophasic flow and should alias
36
Q

What is the acceptable annotation for the sagittal distal femoral vein picture with color?

A

SAG RT/LT FV DIST

37
Q

What are some tips to finding the sagittal femoral vein distal with color? What can we do in terms of pressure to get better doppler?

A
  1. take image immediately proximal to the medial condyle of the knee
  2. increased transducer pressure and using a more posterior window will give better color and spectral doppler
38
Q

What is the acceptable annotation for a sagittal distal spectral image?

A

SAG RT/LT FV DIST/AUG

39
Q

What are some tips in finding the sagittal femoral vein distal image with spectral?

A
  1. Understand that flow in the distal FV may be slower and require adjustments to the doppler scale and gain

40
Q

What is the acceptable annotation for a sagittal popliteal image with color?

A

SAG RT/LT POP V

41
Q

What are some tips to finding the sagittal popliteal image with color?

A
  1. Take image behind the knee noting the veins position superficial to the artery

42
Q

What is the acceptable annotation for the sagittal popliteal vein spectral?

A

SAG RT/LT POP V/AUG

43
Q

What are some tips to find the sagittal popliteal vein with spectral?
