Lymph node FNA techniques?

Lymph node FNA techniques?

  • I will be sampling a sublumbar lymph node tomorrow on a K9 that is an 87 lb Berner.
  • He has a 3″ soft tissue mass in the stifle that his RDVM will be sampling. (Poss. synovial cell sarcoma).
  • Are lymph nodes difficult to aspirate? I know they can be bloody, but I am more interested to know if they slough well to obtain good samples?
  • Recommended needle sizes or technique?

Thank you in advance! – microbat (U/S tech)

Here is the “You Tube” video

Here is the “You Tube” video that Dr Lindquist did showing how to do a FNA

Want to make sure you can reach the LN and there are no major vessels in the way.

Probably not all that different from aspirating a submandibular- except you are using the probe to guide you.

22 gauge to start woodpecker technique… if that doesnt slide out nice then corkscrew technique wiht a new 22 gauge… then rarely have to go to 20 gauge 1.5 inch in really hard LN. this type of lesion you describe usually exfoliates well.
