Ultrasound-guided fine-needle aspiration (FNA) of lymph node(s), (1–2 nodes)

Fine-needle aspiration of a lymph node under ultrasound guidance is a minimally invasive procedure that allows precise collection of cells from the lymph node for cytological examination. Ultrasound ensures accurate needle placement and minimizes the risk of damage to surrounding tissues. The procedure is usually performed for evaluation of 1–2 lymph nodes.

Indications

• Enlargement of lymph nodes of unknown origin
• Suspected infectious, inflammatory, or malignant processes
• Need for precise assessment of lymph node condition prior to treatment

Procedure / Duration

• Local skin preparation and disinfection
• Insertion of a thin needle under ultrasound guidance and collection of material for analysis
• The procedure takes approximately 15–20 minutes and is usually performed on an outpatient basis

Contraindications

• Coagulation disorders or use of anticoagulants without adjustment
• Infections or inflammation at the puncture site
• Allergy to anesthetic agents

Recovery / Restrictions

• Mild discomfort or minor hematoma at the puncture site for 1–2 days
• Avoid pressure or massage on the lymph node for the first 24 hours
• Normal daily activity is not restricted; light physical activity may be limited if necessary

Benefits

• High accuracy of sampling due to ultrasound guidance
• Minimally invasive and quick procedure
• Performed on an outpatient basis without hospitalization
• Fast recovery and minimal discomfort

It is crucial to remember that the information provided here is not intended for self-diagnosis or self-treatment. If you experience any symptoms or exacerbation of a condition, it is essential to seek medical attention for proper diagnostic testing. Only a qualified healthcare professional can make an accurate diagnosis and determine appropriate treatment. To ensure the most accurate and consistent evaluation of test results, it is recommended to have them performed at the same laboratory, as different laboratories may use varying methods and units of measurement for similar tests.
