When is it used?
This technique is used when a tissue diagnosis is required.
What sites can be biopsied?
This technique can be used on virtually any site in the body. Palpable
or superficial lesions are done in our pathology clinic. Deep lesions
may also be biopsied in this manner but they require image-based guidance
and are done by colleagues in the Yale Department of Diagnostic Imaging.
Who is it for?
An aspiration may be done on any patient. There are very few counterindicators
to this technique. Referrals for aspirations come from a wide range
of physicians. Although we provide FNA service in our clinic, many physicians
choose to do the aspirations themselves during the primary office visit.
We provide diagnostic services for aspirations done by any physician.
Why is it used?
The technique can provide a rapid and often definitive answer when trying
to determine the nature of a palpable mass. It is the most economical
mechanism for obtaining a tissue diagnosis. It is acceptable to patients
since it leaves no scar, is nearly painless, and the results can be
obtained in minutes.
Does it hurt?
The procedure is nearly painless, comparable to drawing blood. The needles
used for cell aspiration are the size needles that are used to draw
blood on children or infants (25 ga). Thus the procedure is very well
tolerated without any type of anesthesia.
How long will it take to get the answer?
In most cases, a preliminary diagnosis can be provided within 30 minutes
of the procedure. Generally, we can provide a final diagnosis within
24 hours of the biopsy.
How accurate is it?
Many studies have been done on FNA. The literature generally suggests
sensitivity and specificity in the 90-95%+ range, depending on the site.
How can I schedule an appointment at the Yale FNA clinic?
Clinic appointments may be scheduled by calling (203) 785-4191. Any
palpable lesion may be biopsied. New Patients should have a physicians
referral.
Last year, Yale Pathology reviewed 1148 FNAs. They included a mix of
palpable lesions and material received from image-guided procedures. Specimens
included lesions from the breast, thyroid, lymph node, liver, pancreas,
lung, soft tissues, and head and neck. Of those FNAs reviewed by our service,
65 were performed in our clinic.
