Abstract
Cytologic evaluation of hepatic tissue is an important aspect of the clinical work-up of patients
with liver disease and is routinely based on percutaneous ultrasound-guided fine needle aspirates
(FNA). This study compared the cytologic quality of liver FNAs in dogs and cats obtained with
25-gauge hypodermic or styletted needles. Cytologic criteria included cellularity, blood
contamination, amount of cellular debris, degree of cellular trauma and if a diagnosis was made.
A total of 95 sites were sampled resulting in 380 slides evaluated.
The study showed that it is more likely to have a diagnostic outcome with styletted needles for
hepatic aspirates than hypodermic needles. In all cytologic categories evaluated the styletted
needles had a significant better outcome. However, there was no difference in the cytologic
diagnosis in the majority of cases. The most common cause for a non-diagnostic sample was lack
of cellularity and it was more common with hypodermic needles.
