Pleural needle biopsy   

Overview | Risks | Results

Alternative names:

Closed pleural biopsy; needle biopsy of the pleura

Definition:

The pleura is a thin membrane that lines the lungs and inside of the chest wall. A pleural biopsy involves taking a sample of the pleural tissue to be examined under a microscope. The pleural needle biopsy is done under a local anesthetic.

How the Test is Performed

This test does not have to be done in the hospital. You will be sitting up for the biopsy. The skin at the biopsy site will be cleansed, and a local anesthetic will be injected into the skin and into the pleural membrane. A larger, hollow needle is then inserted through the skin and into the chest cavity. The needle is rotated and as it is taken out, tissue samples are collected. In general, three biopsy samples are taken.  The biopsy site is then bandaged.

At various times during the procedure, you will be asked to sing, hum, or say "eee."  This helps prevent air from getting into the chest cavity, causing pneumothorax (lung collapse).

How to Prepare for the Test

Blood tests will be done before the biopsy, and a chest X-ray may also be taken. You must sign consent forms.

Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:

How the Test will Feel

With the injection of the local anesthetic, there may be a brief prick and a burning sensation.  When the biopsy needle is inserted, you may feel pressure; as it is being withdrawn, you may feel a tugging sensation.

Why the Test is Performed

Pleural biopsy is usually done to determine the cause of a persistent pleural effusion (collection of fluid around the lung) or other abnormality of the pleural membrane.  Common diseases diagnosed by pleural biopsy include tuberculosis and cancer.
