Needle Biopsy of the Lung and Pleura(Transthoracic Needle Aspiration, Percutaneous Needle Aspiration)
by
Julie J. Martin, MS A needle biopsy of the lung or pleural is a procedure that allows doctors to use a needle to take a small sample of tissue so that it can be tested in the laboratory. - Lungs
- Pleura—The pleura is a slippery membrane that covers both the lungs and the chest wall.
- Chest Cavity—The lungs are located in the chest cavity. This space is protected by the breastbone in the front of the body, and the spine in the back, as well as 12 pairs of ribs, which curve around the sides.
This procedure is used to diagnose abnormal tissue on the surface of the lung, in tissue surrounding the lung, or on the chest wall. Possible reasons for abnormal tissue are:
Needle biopsy is very accurate for diagnosing cancer.
A needle biopsy should not be performed if you have the following:
- Certain conditions associated with lung disease, such as bullae and cor pulmonale
- Cysts
- Problems with blood clotting
- Severe hypoxia
- Pulmonary hypertension
- Need for mechanical ventilation
Also, tell your doctor if you are pregnant. - In the days leading up to your procedure, do not start taking any new medications without consulting your doctor.
- The night before, eat a light meal and don’t not eat or drink anything after midnight.
- You may be given pre-procedure medications to prevent or account for certain conditions (e.g., to suppress a cough).
- Before the procedure begins, you will be asked to sign a consent form.
- You may receive a mild sedative to help you relax about an hour before the procedure.
- You may also have an injection of a local anesthetic, usually lidocaine, to numb the area where the needle will be inserted.
Your skin is cleaned with an antiseptic solution. The procedure is done while you are awake and in a seated position, leaning forward, with your arms resting on a table for support. You should remain as still as possible and not cough. The doctor makes a small cut in your skin. Then, while you hold your breath, a biopsy needle, which is a long hollow needle, is inserted through the cut. The needle is inserted between your ribs until it reaches the lung or pleura. The location of the tissue to be tested must be determined. An imaging machine (usually ultrasound or CT) is used to help guide the needle to the exact spot. Your doctor then withdraws some cells through the biopsy needle. - Pressure is put on the site of the incision
- When bleeding has stopped, a bandage is applied
- A few hours after the procedure, a chest x-ray or other imaging technique is used to make sure a lung has not collapsed and that there is no bleeding
A typical procedure takes between 30 and 60 minutes. - Before the procedure, when the local anesthetic is injected, you may feel a brief sting.
- During the procedure, when the needle is inserted, you will probably feel some pressure. If you are having a lung biopsy, you will feel a quick, sharp pain when the needle touches your lung
The biopsy is regarded as a safe procedure. It is seldom associated with any negative effects, but risks include:
- Collapsed lung
(pneumothorax)
- Bleeding
- Infection
- Rarely, the needle can puncture the liver or spleen
- After a lung or pleural biopsy, the recovery time is very short. You may rest for several hours after the procedure so that a nurse can check on you and monitor your recovery. If there are no complications after four hours, you may go home.
- You are advised to rest at home for a day or two
- Avoid strenuous activities for one week
You may remove the bandage after a day or two.
Abnormal results could indicate:
-
Noncancerous tumors (eg, hamatoma or
lipoma
)
-
Cancer (eg, lung cancer,
mesothelioma
, or another cancer that metastasized to the lung)
- Fibrosis (scarring of the lung tissue that occurs after exposure to certain irritants such as coal, asbestos or silica dust)
- Pneumonia
-
Other infections (eg,
tuberculosis
or histoplasmosis)
- Abnormal blood vessels in the lung (arteriovenous malformations, AVMs)
- As a consequence of certain systemic diseases (eg, rheumatoid arthritis, sarcoidosis, or Wegener’s granulomatosis)
Contact your doctor immediately if you experience any of the following:
- Bleeding
- Shortness of breath
- Fast heart beat
- Bluish skin
