Using ultrasound guidance, WTVS uses a needle to safely collect small cell samples—called fine needle aspirates (FNAs)—from organs or structures within the chest (thoracic) or abdomen. These samples are then submitted for microscopic evaluation, helping your veterinarian identify the type of cells present and determine whether inflammation, infection, or cancer may be involved.
Because ultrasound allows precise visualization of internal structures as well as blood vessels, the risks of bleeding or accidental injury to surrounding tissues are low in patients without a known bleeding disorder. Sedation is sometimes recommended for chest samples and may occasionally be used for abdominal FNAs to help minimize discomfort and minimize movement during the procedure.
This minimally invasive technique provides valuable diagnostic information that supports accurate diagnosis and treatment planning—all while being performed in the comfort of your veterinarian’s facility.
